Mechanical ventilation
Intervention
Diagram of an endotracheal tube used in mechanical ventilation. The tube is inserted into the trachea in order to provide air to the lungs. A) Endotracheal tube, which sits in the trachea. B) Inflatable Cuff, which facilitates the inflation of the balloon at the end of the tube to allow it to sit securely in the airway. The balloon can also be deflated via this cuff upon extubation. C) Trachea D) Esophagus

Mechanical ventilation is the medical term for artificial ventilation where mechanical means is used to assist or replace spontaneous breathing. This may involve a machine called a ventilator or the breathing may be assisted by an Anesthesiologist, certified registered nurse anesthetist, physician, physician assistant, respiratory therapist, paramedic, or other suitable person compressing a bag or set of bellows. Mechanical ventilation is termed "invasive" if it involves any instrument penetrating through the mouth (such as an endotracheal tube) or the skin (such as a tracheostomy tube). There are two main modes of mechanical ventilation within the two divisions: positive pressure ventilation, where air (or another gas mix) is pushed into the trachea, and negative pressure ventilation, where air is, in essence, sucked into the lungs.

Mechanical ventilation is indicated when the patient's spontaneous ventilation is inadequate to maintain life. It is also indicated as prophylaxis for imminent collapse of other physiologic functions, or ineffective gas exchange in the lungs. Because mechanical ventilation serves only to provide assistance for breathing and does not cure a disease, the patient's underlying condition should be correctable and should resolve over time. In addition, other factors must be taken into consideration because mechanical ventilation is not without its complications
