The only way for the air to get inside is through the insides of the ET tube. Secondly, they completely seal the airways.
The air escapes through gaps between the mask and the patient’s face or goes through the throat into the patient’s stomach. In comparison, when ventilating through a mask that we put on the patient’s face, there is a huge air leak. Thanks to that, they achieve two major goals.įirstly, they ensure that all of the air pumped during ventilation (e.g., with an Ambu bag) goes directly into the lungs of the patient. Endotracheal intubation is a medical procedure in which a doctor, normally an anesthesiologist, inserts a special plastic tube – an endotracheal tube – into a patient's airways.
