How to Use Non Invasive Ventilation in Acute Respiratory Failure due to Covid ۱۹? Early, Short Time, Low Drive Pressure

It is recommended that patients who are candidates for non-invasive ventilation be admitted to the ICU or a ward reserved only for non-invasive ventilated patients with Covid ۱۹ disease. Due to the risk of transmission of the disease to the patient's staff and nurse, all instructions related to hospital infection control should be followed especially wearing masks and hats and glasses and clothing. Use ventilators with both inhaled and exhaled arms and non-vented masks to reduce the risk of infection with low leakage (۱, ۲).Non-invasive ventilation (NIV) should be started in the early stages of Covid ۱۹ disease. This means that non-invasive ventilation is helpful when the lungs have not yet reached a low compliance level, and the oxygen saturation is not too low, especially in obese patients when atelectasis occurs, the lungs will not open with non-invasive ventilation. Moreover, if recruiting maneuvers are performed, it has many complications such as cardiac arrest, subcutaneous emphysema, pneumomediastinum, and pneumothorax.
