Accepts healthy volunteers: no
Observational model: COHORT
Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Adult patients scheduled for elective surgery using general anesthesia

Brief summary: The Intubation Assist Clinical Study is an observational study of adult patients scheduled for elective surgery under general anesthesia to assess the user interface, assess transthoracic impedance by the ventilation volume and assess transthoracic impedance. Monitoring will begin at the time the patient is pre-oxygenated in preparation for endotracheal intubation and will continue until 30 minutes after intubation is achieved.


Eligibility criteria: Inclusion Criteria:

* 18 years of age or older
* Requiring intubation and assisted ventilation
* Patient undergoing elective surgery
* Able to give informed consent

Exclusion Criteria:

* Skin condition that would interfere with electrodes
* Inability/failure to intubate
* Pregnancy
* Surgery that prevents the application of electrodes and monitoring equipment.
* Previous excision of complete or partial lung; congenital lung abnormalities.

Primary outcomes:
measure: Assessment of the user interface
timeFrame: Assessment will be made after using Intubation Assist approximately 30 minutes after successful intubation
Secondary outcomes:
measure: Assessment of transthoracic impedance
timeFrame: Impedance measurements will be collected during intubation and will not exceed 30 minutes from the start of intubation
Other outcomes:
