Endotracheal Intubation I: Procedure
525
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Endotracheal Tube Extubation
306
Endotracheal tube extubation is a critical procedure in weaning patients from mechanical ventilation. It involves physically removing the oral or nasal endotracheal (ET) tube, marking the final step in liberating a patient from ventilatory support.
Procedure
Extubation removes the endotracheal tube (ETT) from the patient on mechanical ventilation. It requires a well-coordinated, multidisciplinary approach involving physicians, nurses, respiratory therapists, and other healthcare professionals....

Endotracheal Intubation II: Nursing Management
406
Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
