Abstract
Acute respiratory failure is a common disease with numerous complications and high mortality rate. The ventilatory support is a cornerstone in management of ARF when the conservative measures fail. The use of invasive MV sometimes is inevitable life saving step in management of advanced cases of ARF. However, being associated with numerous complications, the invasive MV should be discontinued at the earliest possible time in the course of a patient’s illness.
There are numerous indications for endotracheal intubation and mechanical ventilation, but in general, mechanical ventilation should be considered when there are clinical or laboratory signs that the patient cannot maintain an airway or adequate oxygenation or ventilation. The decision to initiate mechanical ventilation should be based on clinical judgment that considers the entire clinical situation and should not be delayed until the patient is in extremis.
