Mechanical Ventilation (MV) is a life-saving medical intervention used to assist or replace the breathing of critically ill patients who cannot breathe on their own. MV involves the use of a machine to deliver oxygen to the patient's lungs and remove carbon dioxide from the body. It is typically used in intensive care units and emergency departments for patients with respiratory failure or other severe respiratory conditions. MV can be invasive or noninvasive, depending on the patient's condition and the type of support required. Proper management of MV is crucial, as it can cause complications and increase the risk of infection if not properly monitored.
