Time-domain investigation of wave propagation in effective metamaterial models
Authors: Lombard Bruno
Published: December 2021

Wave propagation in microstructured media is often expressed in the frequency domain. This is particularly the case for resonant media, where resonance frequencies are explicitly involved in the PDE (e.g. Helmholtz resonators, high contrast media, etc.). However, it is possible to describe these phenomena based on the auxiliary field formalism. It then becomes possible to use the powerful mathematical and numerical tools specific to hyperbolic systems. The temporal approach allows to study the time of the establishment of periodic phenomena with a single simulation, and is particularly useful when the studied system presents nonlinearities.

We will illustrate the subject by reviewing different cases of interest for the “metamaterials” community:

1. High contrast volume homogenization (coll: Cédric Bellis)
2. Resonant outer cloak (coll: Sébastien Guenneau and Cédric Bellis)
3. Resonant metasurfaces (Marie Touboul’s PhD thesis, coll: Cédric Bellis, Agnès Maurel, Kim Pham and Jean-Jacques Marigo)
4. Dynamics of solids with nonlinear cracks (coll. Raphaël Assier, Cédric Bellis, Marie Touboul)
Theoretical thermotics and thermal metamaterials: A brief review
Authors: Huang Jiping
Published: December 2021

Transformation thermotics [1-5] is a kind of theoretical method which is based on the coordinate transformation between two different spaces, which can precisely couple geometric structure parameters into physical quantities such as thermal conductivity. This method makes it possible to artificially tailor the geometric structure to accurately control the flow of heat. Free control of heat flux is always a dream of human beings. For this purpose, thermal metamaterials come to appear [6,7], which just originate from the theory of transformation thermotics. Here, I review the crucial theoretical and experimental research progresses in this field after the birth of transformation thermotics for steady-state thermal conduction in 2008 [1,2]. They mainly include the following novel thermal phenomena or functional metamaterial devices: thermal cloak, thermal concentrator, thermal rotator, macroscopic thermal diode, thermal camouflage, thermal transparency, thermal imitator, thermal golden touch, ultra-low thermal conductivity, thermocrystal, zero-energy consumption and negative-energy consumption in ambient temperature difference, thermal anti-parity-time symmetry, thermal convection cloak/concentrator/camouflage, and daily radiation cooling. I will present the relevant microscopic or macroscopic heat-transfer mechanisms and make some prospects for the future.
Self-collimation, Veselago lens, Dirac cones and embedded states in continuum in acoustics without phononic crystals and metamaterials
Authors: Maznev Alexei
Published: December 2021

The concepts of photonic crystals and metamaterials initially appeared in optics and electromagnetism, and were subsequently extended to acoustic waves. However, a number of phenomena thought to be specific to these “artificial” media have been observed in solid state acoustics with conventional materials – in some cases well before the advent of metamaterials and photonic/phononic crystals. In this talk, which will cover both historical and recent research, we will discuss several such phenomena: (i) “self-collimation” of bulk and surface acoustic waves in natural crystals; (ii) negative group velocity, Veselago lens and Dirac cones exhibited by guided acoustic waves in plates; (iii) robust embedded states in continuum on natural crystal surfaces and in simple layered structures.
On the compact wave dynamics of tensegrity metamaterials
Authors: Fraternali Fernando
Published: December 2021

A research subject attracting remarkable attention from many areas of engineering concerns the use of noninvasive tools to target defects in materials, as well as devices for monitoring structural health in materials and structures. Most of current methods for the focusing and defocusing of acoustic waves (based mainly on exploiting linear acoustic effects) present the problem of having essentially little to no tunability ranges and poorly scalable dimensions. The use of highly nonlinear systems, allowing for a high level of control over the acoustic speed may enable the creation of revolutionary types of devices with far more advanced wave-focusing methodologies.This talk illustrates the employment of tensegrity metamaterials featuring elastically stiffening/hardening response for the fabrication of tunable focus acoustic lenses or innovative devices for monitoring structural health and damage detection in materials and structures. These devices support extremely compact compression waves in multiple dimensions. Previous research on 1D systems is generalized to 2D and 3D tensegrity beams and plates with stiffening-type response (acting as phononic crystals). The presented results reveal that the dynamics of such systems is characterized by the thermalization of the lattice nearby the impacted regions of the boundary. The portion of the absorbed energy moving along the longitudinal direction is transported by compression waves with compact support. Such waves emerge with nearly constant speed, and slight modifications of their spatial shape and amplitude, after collisions with compression waves traveling in opposite direction.
Topological metamaterials for robust signal and energy manipulation
Authors: Fleury Romain
Published: December 2021

Topological metamaterials are artificially engineered structures that confer to the waves that propagate through them a property, for example the presence of a given mode, that is robust to continuous modifications of the metamaterial, such as geometrical deformations, local defects, or irregularities in the wave path. In this talk, I will first explore how robust topological modes can be leveraged as building blocks to engineer resilient scattering responses1,2. Such topological scattering, which enables filtering signals without stringent requirements on the system’s geometry3, is experimentally demonstrated with acoustic waves. We will then discuss the relevance of topology to robust energy concentration or manipulation, in particular using second order topological wave insulators leveraging non-linearity4, or combining topological concepts with classical metamaterial effects such as near-zero-index supercoupling5. Altogether, this talk demonstrates that the field of topology is now sufficiently mature to move from purely physics-driven explorations towards exciting application-oriented developments6.
Acoustic metasurfaces and their application to turbulent flow
Authors: Starkey Tim
Published: December 2021

The use of surface structures can have a significant impact on the pressure fluctuations that manifest above them. Acoustic metamaterials that comprise structured surfaces have been designed to influence the acoustic pressure field for a variety of applications such as acoustic filtering, focusing, and absorption, whilst in the aerodynamics of turbulent boundary layer flows, surface treatments can cause significant changes to the sound generated from, and pressure fluctuations present within, the flow. So, the question arises, can we apply acoustic metamaterial concepts as a strategy to influence a turbulent flow?

In principle, metasurfaces used to control acoustic fields should also respond to evanescent pressure fluctuations generated by turbulence. However, interfacing a metasurface and boundary layer poses some challenges, not least in the large disparity between acoustic and flow scales at low Mach number, and the need to avoid metasurface configurations that generate drag or other undesirable flow effects.

In this talk I will discuss our recent work on acoustic surface waves and their application to a turbulent fluid flow. First I will talk about the characteristics and structures that support acoustic surface wave propagation in a quiescent ‘wholly acoustics’ environment. I will then present the strategy developed with collaborators at Virginia Tech, that interfaces a cavity-type metasurface with a turbulent flow using a hydrodynamically smooth but acoustically transparent membrane. Our experiments demonstrate the excitation of a bound acoustic mode using the stochastic near-field pressure fluctuations of a turbulent flow. The tested metasurfaces demonstrate a route for acoustic surface mode dispersions with reduced phase velocities to match to the convective velocity of the turbulent structures.We view this as an important first step in interfacing flows and metamaterials, with potential applications to the control of flow-generated edge noise or energy harvesting.
3D chiral mechanical metamaterials
Authors: Wegener Martin
Published: December 2021

Calling an object or a metamaterial handed or “chiral” requires it to exhibit (i) broken space-inversion symmetry, (ii) no mirror planes, and (iii) no rotation-reflection symmetries. The absence of these symmetries allows for certain effective material behaviour that would otherwise be forbidden by symmetry. Here, we review our recent progress on three-dimensional (3D) chiral mechanical metamaterials in the linear elastic regime. This includes tailored characteristic length scales of push-to-twist conversion behaviour, ultrasound experiments on acoustical activity with transient nanometer-precision displacement-detection, the mapping of this dynamic behaviour (as well as of the static behaviour) onto effective-medium descriptions beyond Cauchy elasticity, and the possibility of isotropic acoustical activity in rationally designed 3D chiral quasi-crystalline mechanical metamaterials.
Scattering electromagnetic eigenstates of a two-constituent composite and their exploitation for calculating a physical field
Authors: Bergman David
Published: December 2021

The spectral representation of an electric field in a two-constituent composite medium is revisited. A theory is developed for calculating the electromagnetic (EM) eigenstates of Maxwell’s equations for such a composite where the magnetic permeability as well as the electric permittivity have different uniform values in the two constituents. The physical electric field E(r) produced in the system either by a given incident field or by a given source current density is expanded in this set of biorthogonal eigenstates for any position r. If the microstructure consists of a cluster of separate inclusions in a uniform host medium then the EM eigenstates of all the isolated inclusions can also be used to calculate E(r). Once all these eigenstates are known for a given host and a given microstructure then calculation of E(r) only involves performing three-dimensional integrals of known functions and solving sets of linear algebraic equations.
Metastructures for Wave and Diffusion Phenomena
Authors: Engheta Nader
Published: December 2021

Materials are often used to manipulate waves and fields. Metamaterials have provided far-reaching possibilities in achieving “extremes” in such wave-matter interaction. Various exciting functionalities have been achieved in exploiting metamaterials and metasurfaces in nanophotonics and nano-optics. We have been exploring how spatiotemporal metamaterials can give us new platforms in structuring light for exploiting waves to do certain useful functions for us. Several scenarios are being investigated in my group. As one scenario, we have been developing metastructure platforms that can perform analog computation, such as solving integral and differential equations and inverting matrices, with waves as waves interact with them. Such “metamaterial machines” can function as wave-based analog computing machines, suitable for micro- and nanoscale integration. Another scenario deals with 4-dimensional (4D) metamaterials, in which temporal variation of material parameters is added to the tools of spatial inhomogeneities for manipulating light-matter interaction with spatiotemporal platforms. These 4D structures can also be used for manipulation of diffusion to achieve asymmetric diffusion and trapping. The third category of structured waves is achieved in the near-zero-index materials and associated photonic doping that exhibit unique features in light-matter interaction, opening doors to exciting new wave-based and quantum optical features. In this talk, I will present some of our ongoing work in the above topics, and will forecast possible future research directions in these paradigms.
Nanophononic metamaterials: Thermal conductivity reduction by “millions” of local resonances
Authors: Hussein Mahmoud I.
Published: December 2021

The concept of a metamaterial has been introduced in electromagnetics and acoustics as an artificially structured locally resonant material that exhibits unique, and often extreme, effective properties in the subwavelength regime. Here we introduce the notion of a locally resonant metamaterial to the area of heat transfer at the nanoscale. In contrast to electromagnetic and acoustic metamaterials, the underlying phenomenon is not limited to the subwavelength regime and does not depend on an effective properties characterization. This new type of metamaterial–termed nanophononic metamaterial (NPM) [1-3]–is also fundamentally different from what is known as thermal metamaterials, which are primarily concerned with transformation heat diffusion and not wave-based phenomena.

One realization of an NPM is a freestanding silicon membrane (thin film) with a periodic array of nanoscale pillars erected on one or both free surfaces. Heat is transported along the membrane portion of this nanostructured material as a succession of propagating vibrational waves, phonons. The atoms making up the minuscule pillars on their part generate resonant vibrational waves, which we describe as vibrons. These two types of waves linearly interact causing a mode coupling for each pair which appears as an avoided crossing in the pillared membrane’s phonon band structure. This in turn (1) enables the generation of new modes localized in the nanopillar portion(s) and (2) reduces the base membrane phonon group velocities around the coupling regions. In addition, the phonon lifetimes drop due to changes in the scattering environment, including both phonon-phonon scattering and boundary scattering. These three effects inhibit the in-plane thermal transport. Given that the number of vibrons scales with the number of degrees of freedom of a nanopillar, these effects intensify as the size of the nanopillar(s) increases–possibly reaching millions of vibrons–and in principle may be tuned to influence the entire phonon spectrum (which for silicon extends up to over 17 THz). This novel phenomenon thus provides an opportunity for achieving exceptionally strong reductions in the thermal conductivity, with excellent potential for utilization in thermoelectric energy conversion.
Towards the engineering design of metamaterials’ structures through micromorphic enriched continuum modeling
Authors: Madeo Angela
Published: December 2021

In this talk, I will show how enriched continuum models of the micromorphic type can be used to describe the dynamical behavior of anisotropic mechanical metamaterials. I will show to which extent one of the the proposed models, that I contributed to pioneer, is able to capture all the main microscopic and macroscopic characteristics of the targeted metamaterials, namely, stiffness, anisotropy, dispersion and band-gaps. The simple structure of our material model, which simultaneously lives on a micro-, a meso- and a macroscopic scale, requires only the identification of a limited number of frequency-independent parameters thus allowing the introduction of pertinent boundary conditions to be imposed at metamaterials’ boundaries when the model is framed in the context of Variational Principles. I will show how this model can be applied to the study of the scattering properties of finite-size metamaterials’ structures thus opening new perspectives for metastructural engineering design.
Reflectionless Modes: an alternative spectrum for wave scattering
Authors: Pagneux Vincent
Published: December 2021

To characterize scattering resonances, a useful tool is the complex resonance spectrum corresponding to eigenmodes (QNM) able to leak energy. However, for reflection/transmission problems (e.g. waveguides, gratings or screens), the complex resonance spectrum does not directly quantify transmission efficiency, and the question of good or perfect transmission is of tremendous importance in many topics of intense study in wave physics: extraordinary optical transmission, topological states immune to backscattering, perfect transmission resonances, transmission eigenchannels through disordered media, reflectionless metamaterials or metasurfaces.

We present here an alternative spectrum allowing one to identify situations where perfect transmissions occur [1]. The operator yielding the spectrum of reflectionless modes is non-selfadjoint, and it is PT-symmetric for systems with spatial mirror symmetry. Eigenmodes (reflectionless modes) and eigenvalues (reflectionless complex frequencies) will be presented in various scattering situation, from the simplest 1D setup to several 2D waveguide geometries.
Quasiperiodic composites: Forward and inverse homogenization
Authors: Cherkaev Elena
Published: December 2021

Quasiperiodic materials present a novel class of metamaterials that possess extraordinary mechanical, thermal, and electromagnetic properties, such as superconductivity, extremely low thermal conductivity, unusual mechanical properties, and diffraction patterns forbidden by crystallographic symmetries. The properties of such materials critically depend on the microstructure of the media. The talk will discuss the effective properties and homogenized equations governing the effective behavior of quasiperiodic composites. I will also address an inverse homogenization problem of reconstructing information about microstructural parameters from known effective properties. An approach to the inverse homogenization problem is based on the Stieltjes analytic representation which involves a spectral measure of a self-adjoint operator. The spectral measure contains all information about the geometry of the composite and can be uniquely recovered from effective measurements given in an interval of frequency. Stieltjes analytic representation also allows us to determine spectral characteristics and establish an analogy between Anderson transition in quantum transport and transition from ordered to disordered behavior in classical transport in composites without scattering or wave interference effects.
Multistable inflatable origami – from deployable structures to robots
Authors: Bertoldi Katia
Published: December 2021

Multistable structures can reversibly change between multiple stable configurations when a sufficient energetic input is provided. While originally the field focused on understanding what governs the snapping, more recently it has been shown that these systems also provide a powerful platform to design a wide range of smart structures. In this talk, I will first show that pressure-deployable origami structures characterized by two stable configurations provide opportunities for a new generation of large-scale inflatable structures that lock in place after deployment and provide a robust enclosure through their rigid faces. Then, I will demonstrate that the bistable origami modules provide an ideal platform to design actuators that can switch between different configurations, reach multiple, pre-defined targets in space, and move along complex trajectories. Unlike previously proposed robots that require complex input control of multiple actuators, a single input signal suffices to activate our robot, as all features required for functionality are embedded into the architecture of the building blocks.
Topological mode steering across wave physics
Authors: Makwana Mehul
Published: December 2021

Steering waves around sharp bends and splitting their energy between different channels, in a robust and lossless manner, is of interest across many areas of engineering and physics. The seminal work of Mekis et. al [Phys. Rev. Lett. 18, 3787, 1996] in photonic crystals using cavity waveguides to perform this is now used widely in devices. A very active area of current research involves trying to use ideas originating in quantum mechanics, and from topological insulators, for similar purposes, but with the added potential of broadband performance, and enhanced robustness. In this presentation, I will relay the main principles of topological modes in classical wave systems and elucidate their benefits and shortcomings. Theoretical, computation and experimental results will be used to highlight a particular class of these insulators that contain passive elements and are solely reliant upon geometrical properties of the structured media.

Feminist Food Justice and Food Sovereignty
Authors: Sachs Carolyn
Published: December 2021

Feminist food justice builds on the food sovereignty and food justice movements and aims to overcome intersectional inequities in the food system. Feminist food justice emphasizes four strategies: supporting food production at multiple scales, justice for workers beyond the farm, revaluing food work that feeds families, and providing good food for all. This article, written at the time of the global coronavirus pandemic in 2020–2021, revisits the vision for feminist food justice, discusses how it relates to the food sovereignty and food justice movements, and then reframes feminist food justice given what we have learned about global and local food systems during the pandemic.

Context: Neurofibromatosis type 1 (NF1) is a genetic condition characterized by “café au lait” spots, axillary and inguinal ephelides and cutaneous neurofibromas. Case report: A 16 year-old famele patient with description that her father and other family members had the “café au lait” spots. From the age of 5, she started with slight facial asymmetry, which increased over time. On physical exam at 16 years old, she had facial asymmetry, convergent strabismus with a left lower eyelid cleft than the contralateral cleft, in addition to left eyelid ptosis and left eye proptosis. There were also “café au lait” spots and ephelides on the body. Computerized tomography scan of the skull showed an important architecture distortion of the skull base’s bones of the anterior and middle fossa of the skull, sphenoid dysplasia and left orbital encephalocele. In the ophthalmological evaluation, corneal opacity and ocular proptosis involving the left eye were found. At the age of 17, she underwent a complex craniotomy with craniofacial reconstruction due to temporo-fronto-orbital dysplasia. Conclusions: The clinical findings and the patient’s family history were compatible with the diagnosis of NF1. Bone changes, such as sphenoid dysplasia, may be present and lead to symptoms. In this case, bone changes in the skull led to the occurrence of an encephalocele, which in turn caused an ocular proptosis.

Published: December 2021

Context: Inversion-duplication-deletion (invdupdel) involving the short arm of chromosome 5 is considered a complex and extremely rare alteration. Case report: A female patient was born prematurely at 32 weeks and was delivered by cesarean section, weighing 2,086 grams, with an Apgar score in the fifth minute of 7. After birth, she needed invasive mechanical ventilation. A nasofibrolaryngoscopy was performed, which revealed the rear projection of the tongue base. The speech-language evaluation showed a swallowing disorder. The patient needed to be tracheostomized and evolved with episodes of cardiorespiratory arrest. A zone 2 of immaturity was identified in both eyes. Then, gastroesophageal reflux was also diagnosed. Cerebral ultrasound showed moderate lateral ventricles dilation. High resolution GTG-banding karyotype identified an inverted and partial duplication of the chromosome’s 5 short arm, with a probable deletion of its distal segment: 46,XX,invdup(5) (p13.3->p15.33:: p15.33->qter) [23]. The parents’ karyotype was normal. At 2 months, the patient had dolichocephaly; bitemporal narrowing; hypertelorism; and down slanting palpebral fissures with blepharophimosis; low-set and posteriorly rotated ears; leftover skin at neck and bilateral plantar creases between the first, second and third toes. Conclusions: Invdupdel of the short arm of chromosome 5 is a very rare chromosomal alteration. Neurological findings seem to be part of its clinical manifestations, especially dilated lateral ventricles. More reports will be essential for understanding its clinical spectrum.

Published: December 2021

Background: Glioblastoma is a primary malignant tumor of the central nervous system with 12 to 15 month survival. Its prognosis, considering the initial diagnosis, equals to stage 4 of other types of cancer, being recommended to consider palliative care, with advanced care planning, at an early stage of the disease. Such care is complex due to the significant symptoms, being necessary to reduce the symptomatic charge to maintain the patient’s quality of life. Objective: Analyze the early practice of palliation in patients with glioblastoma. Methods: A literature review was carried out on the PubMed, BVS and Scielo platforms using the descriptors: “Glioblastoma” AND “Palliative Care.” 7 articles were selected in the english language, published in the last 5 years. Results: The quality of life of patients with glioblastoma gradually reduces. In that sense, cognitive decline compromises end-of-life care with relation to patient autonomy. However, antecipate guidelines were found completed late to the course of the disease, possibly after loss of decisionmaking capacity. Moreover, despite the proven benefits of palliation, early involvement of palliative care is rare in neuro- oncology, with the excessive use of chemotherapy among terminal patients. Conclusions: The late practice of palliation and of early guidelines in patients with glioblastoma affect the management of symptoms and quality of life of those patients.

Background: Stroke is the second leading cause of death in the world, causing thousands of hospital admissions and whose morbidity and health care costs are high. Objectives: To analyze the temporal behavior of hospitalization of elderly people due to stroke in Brazil, regions and Federation Units (UF), 2008- 2019. Design and setting: Ecological study. The space units were Brazil, its regions and Federation Units. Methods: Data were collected on the DATASUS online platform: number of admissions, number of Hospitalization Authorizations approved (AIH), total AIH value (R$), average AIH value (R$), and average value hospitalizations (R$). Was used the joinpoint regression model to calculate the Annual Percentage Change (APC) and the Average Annual Percent Change (AAPC) with 95% confidence interval and a 5% significance level. Results: Approximately 1.4 million hospitalizations were identified in Brazil, with a total cost of R$ 1.6 billion reais and an average of 1.1 thousand reais. The Southeast region stood out in the number of hospitalizations (n = 574399; 42.1%), approved AIH (n = 574625; 42.1%) and total amount (R $ 677,444,257.54; 43.4%). Throughout the time series, the number of hospitalizations increased by 52.3% and the number of approved AIH increased by 52.4%. The mean values of hospitalizations and AIH increased, respectively, 55.4% (AAPC: 3.9; CI: 3.2; 4.5) and 55.3% (AAPC: 3.9; CI: 3, 2; 4.5), while the total value of hospitalizations increased by 134.9% (AAPC 8.0; CI: 6.9; 9.1). Conclusions: There was an increase in variables related to hospitalization and stroke costs in the elderly in Brazil.

Aim: Prevalence and determining factors of refractive errors among the medical students in FMU, Faisalabad. Methodology: Cross-sectional quantitative study conducted in Faisalabad Medical University from 01-03-2020 to 15-12-2020 after approval from institutional review committee. All students of MBBS in FMU were included in this study. A structured questionnaire was used to collect the required quantitative information. SPSS version 26 was used for analysis. Results: Prevalence of refractive error is 49%. Females were 59% and males were 41%. More students i.e. 85.2% were suffering from myopia. In our study, usage of electronic devices i.e. mobile phones especially was one of the risk factors in developing refractive errors. 20.6% students having refractive error said that they use mobile phone for 4 hours, 30.2% having refractive error said that they watch TV for one hour, 23.3% having refractive error said that they play video games for one hour. For the correction of the refractive error, 184 students i.e. 97.4% used spectacles whereas only 5 (2.6%) students used contact lenses. It is observed in this study that contact lenses were only used by those students having refractive error <1.5. Conclusion: Refractive errors were a significant cause of visual impairment among medical students. The prolonged use of electronic devices especially mobile phones should be discouraged. Keywords: Refractive errors, myopia, electronic devices, mobile phone

Published: December 2021

Background: Ovulation induction with clomiphene citrate in women with infertility has been practiced more than 40% years but in infertile patients this treatment plan proved to be ineffective with multiple complication. Body weight plays an important role modulating reproductive development and functioning. Aim: To observe the effects on body weight of female albino rat after use of clomiphene citrate and letrozole for consecutive 1-4 estrous cycles Method: Eighty four adult female Albino rats were equally divided into three groups for this research. Body weight of each rat was measured before and after the experiment. Vaginal smear cytology of each rat was performed to study different phases of estrous cycle. Control group A was given normal saline orally , In Experimental group B rats were given letrozole (Femara) at dose 5mg/kg orally and in Experimental group C rats were given clomiphene citrate at dose 100ug/kg orally. Results: Significant weight gain is observed in rats taking clomiphene citrate as compared to letrozole Conclusion : Comiphene citrate directly affects the body weight which indirectly reduces the ovulation induction and pregnancy rate. Letrozole is good alternate for ovulation induction and for CC resistant patients. Keywords: Estrous cycle, body weight, citrate and letrozole

Background: The Covid-19 pandemic has wreaked havoc throughout the world, with 150 million cases to date and over 3 million lives claimed worldwide. Aim: To explored the difference in levels of SaO2 of COVID-19 positive patients with and without COPD. Study design: Experimental Study. Methodology: From May2020 to 2021 patients admitted at Aziz Bhatti Shaheed hospital were included in this studies. COVID-19 was confirmed by RT-PCR.COPD was confirmed by using GOLD standard of diagnostic criteria. SaO2 was measured by using pulse oximeter and confirmed by blood samples measurement of SaO2. Statistical analysis: SPSS version 22 was used for data analysis. Paired sample t test was performed to evaluate the hypoxia levels between three pairs among the time distribution of 1st, 3rd, and 6th, day. Results: Levels of SaO2 were statistically significant between COVID-19 positive patients and COVID-19 positive patients with COPD. We calculated the levels of SaO2 at day1, 3rd, and 6th day and results were significant to show that COPD might be having some protective effect against hypoxia and that might be due to use of medications or adaptation of pulmonary cells. Conclusion: It was concluded that levels of SaO2 was significantly reduced in COVID-19 patients without COPD in comparison to patients without COPD. Keywords: COVID-19, COPD and SaO2.
