Tracheal intubation is a medical procedure used to secure a patient's airway by inserting a tube into the trachea, or windpipe. This is typically done in emergency situations, during surgery, or in intensive care units. Tracheal intubation allows for the delivery of oxygen and other gases directly into the lungs and helps prevent aspiration of fluids or debris into the lungs. It is a critical procedure that requires skill and training to perform safely and effectively. Research in this area focuses on improving techniques, equipment, and training methods to enhance success rates and reduce complications associated with tracheal intubation.
