Endotracheal Intubation I: Procedure
7.3K
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...

Cardiopulmonary Resuscitation II: ACLS Airway Management
514
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Endotracheal Tube Extubation
3.6K
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....

Mechanical Ventilation I: Indication and Settings
2.5K
Mechanical ventilation is a life-saving technique for managing acute respiratory failure and other respiratory complications. The process involves using a machine known as a ventilator to supply oxygen to the lungs and assist in removing carbon dioxide. It serves as a bridge to long-term mechanical ventilation or a temporary measure until ventilatory support is discontinued. The ventilator can maintain this function for a prolonged period, providing critical support for patients until they can...

Mechanical Ventilation II: Invasive Ventilation
620
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Endotracheal Intubation II: Nursing Management
2.4K
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.
