Endotracheal Tube Extubation
1.4K
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 I: Procedure
3.0K
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 Intubation II: Nursing Management
1.2K
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.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Tracheostomy: Procedure and Tubes
1.2K
A tracheostomy is a surgical procedure that creates an artificial opening into the trachea, typically at the second or third cartilaginous ring level. This opening allows the insertion of a tracheostomy tube, which can replace an endotracheal tube, provide mechanical ventilation, bypass an upper airway obstruction, or remove accumulated tracheobronchial secretions.
Tracheostomy tubes can be made of semiflexible plastic (polyurethane or silicone), rigid plastic, or metal, and they come in...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
82
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway...

Tracheostomy Decannulation
387
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...
