Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Tracheostomy Care I: Pre-procedural Steps

Tracheostomy Care I: Pre-procedural Steps

A tracheostomy is a surgical technique that involves making an incision in the neck to provide access to the trachea. It is frequently used in medical conditions such as airway obstruction and prolonged mechanical ventilation. Effective nursing management is crucial for the long-term success of a tracheostomy.
Required Equipment
The equipment necessary for tracheostomy care includes:

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy Suctioning I: Pre-Procedural Steps

Tracheostomy suctioning is a critical procedure healthcare professionals perform to maintain a patent airway in patients with a tracheostomy tube. This procedure is necessary when secretions accumulate in the airway, causing respiratory distress. Here is a step-wise procedural guide for performing tracheostomy suctioning using an open system.
Equipment Required
First, gather all necessary equipment: a sterile suction catheter, a sterile disposable container, sterile gloves, a towel or...

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques

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 interventions are...

Tracheostomy Care II: Procedure

Tracheostomy Care II: Procedure

Tracheostomy care is an essential nursing skill that involves cleaning and maintaining a tracheostomy tube to prevent infection and other complications. Here's a step-by-step guide explaining each procedure with its rationale. Note that disposable gloves are to be worn at all times and changed as often as needed to maintain a sterile work environment, and to protect both patient and healthcare worker.
Step 1: Perform hand hygiene, and put on personal protective equipment: gown, gloves, mask and...

Tracheostomy: Procedure and Tubes

Tracheostomy: Procedure and Tubes

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...
