monitoring devices (e.g., electroencephalography and photoelectric devices for the saturation of partial pressure oxygen) to make diagnostic and treatment decisions [5; 6]. Ventilator monitoring, the hallmark of the ICU, keeps patients with respiratory failure alive by delivering oxygen to the alveoli during artificially controlled breathing. Mechanical ventilation is used to rest respiratory muscles and manipulate breathing patterns to enhance ventilation and oxidation when normal gas exchange cannot be expected from spontaneous breathing alone. Unlike spontaneous breathing, which starts through negative pressure due to the contraction of the diaphragm, most ventilators induce inspiration through positive pressure [7]. These ventilators can help clinical staff make a comprehensive judgment by providing various characteristic waveforms, such as the volume-pressure loop, flow-pressure loop, auto-positive end-expiratory pressure, and air leak [8; 9]. For instance, the monitor for mechanical ventilation displays the patient's response after adjusting the ventilation system and can select the optimal control parameters for patients with respiratory failure [10]. These parameters are monitored in real time by clinical staff and require immediate attention, as they play a critical role in acute hypoxic and hypercapnic respiratory failure, as well as severe metabolic acidosis or alkalosis [11; 12]. Although it is very important to monitor the ventilator in real time, there are several limitations in terms of monitoring patients in the ICU. First, the ability to comprehensively diagnose and treat incidents caused by ventilator-induced lung injuries and customize responses for each patient is limited [7; 13]. Appropriate parameter control is required based on continuous observation and trend review by the clinical staff to provide gas exchange with a ventilator that can minimize lung damage. In this case, it is necessary to comprehensively store and manage the patient's whole-cycle information and provide it to the clinical staff. This can play a crucial role in preventing lung damage caused by ventilators through breathing management tailored to precision medicine [13]. Second, the noise level in an ICU with various monitoring devices and many clinical staff members is very high, which can distract the clinical staff from focusing on individual patient ventilator monitoring. Excessive sound pressure levels in ICUs are often reported to be in the 50-70 dB(A) range, with levels above 40 dB(A) known to cause difficulty in concentration [14; 15; 16; 17]. The World Health Organization (WHO) guidelines recommend that levels should not exceed 35 dB(A) in most spaces where patients are treated or observed, as patients are less able to cope with stress [18]. In addition, when false and nonactionable alarms that do not require specific intervention are excluded from the total number of alarms in the ICU, the number of actionable alarms ranges from <1% to 26% [19]. Therefore, excessive alarms can cause clinical staff to lose focus on patients, which means that they may disable or silence alarms [17; 19]. Ultimately, there is a need to reduce alarm fatigue among the clinical staff through central monitoring. Finally, respiratory diseases, such as the coronavirus disease 2019 (COVID-19), require new treatment protocols for respiratory monitoring in the ICU. Respiratory infectious diseases readily transmit to others, increasing the infection risk for clinical staff and demand for additional isolation beds [20]. Monitoring patients with respiratory failure who are on mechanical ventilator or extracorporeal membrane oxygenation (ECMO) therapy in an isolated room is difficult [21; 22; 23]. Contactless real-time integration of ventilator monitoring is required to minimize infections in clinical staff and reduce the nursing workload in ICUs. Tele-ICUs can be an alternative to overcome these problems.
