Acute respiratory failure (ARF) is defined as a condition in which the patient's arterial oxygen pressure (PaO2) is less than 60 mmHg and/or arterial carbon dioxide pressure (PaCO2) is more than 45 mmHg. This result occurs when the weakness of the respiratory system leads to the inability to transfer oxygen from the air to the blood or to remove carbon dioxide from the blood and transfer it to the surrounding air, and various mechanisms such as hypoventilation, diffusion disorder, shunt, ventila
