Trachea01:22

Trachea

1.4K
The trachea, commonly known as the windpipe, is a vital part of the human respiratory system. It serves as a passageway for air to travel between the larynx and the bronchi, allowing oxygen to reach the lungs. Let's explore its anatomical features, dimensions, layers of the tracheal wall, associated muscles, and the functions of its parts.
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

Tracheostomy: Procedure and Tubes01:28

Tracheostomy: Procedure and Tubes

340
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...

Tracheostomy Decannulation01:21

Tracheostomy Decannulation

74
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...

Tracheostomy Care I: Pre-procedural Steps01:16

Tracheostomy Care I: Pre-procedural Steps

110
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:

Endotracheal Intubation I: Procedure01:15

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...

Oxygen Delivering System III: Tracheostomy and T-piece01:23

Oxygen Delivering System III: Tracheostomy and T-piece

316
Oxygen delivery is critical in clinical care, especially for patients with respiratory disorders or those undergoing surgical procedures. Various systems, such as tracheostomy and the T-piece, deliver oxygen to the lungs, ensuring adequate arterial oxygenation.
Tracheostomy
A tracheostomy is a surgically created opening (stoma) in the anterior part of the trachea. It is used to establish a patient airway, bypass an upper airway obstruction, simplify the removal of secretions, permit long-term...

Area of Science:

  • Medical Devices
  • Surgical Procedures
  • Respiratory Medicine

Background:

  • Airway occlusions (CAO) necessitate effective management, often involving airway stenting.
  • Silicone stents are commonly used for CAO, providing flexible yet firm support to relieve dyspnea.
  • Current stenting methods may require specialized equipment like rigid scopes, limiting their use in remote or urgent settings.

Purpose of the Study:

  • To develop and evaluate a novel, simplified stenting procedure for airway occlusions.
  • To create a method applicable in urgent, remote situations without requiring a rigid scope.
  • To assess the feasibility of a new stenting technique using readily available materials.

Main Methods:

  • A pilot study was conducted using two mature sheep.
  • Endotracheal tubes of size 8.5 were adapted for stenting.
  • Silicone stents were placed in the animals' tracheas for a duration of two months.

Main Results:

  • The novel stenting procedure was successfully implemented in the tracheas of both sheep.
  • The method demonstrated applicability without limitations related to trachea size.
  • The procedure was noted to be fast, simple, and cheap to perform.

Conclusions:

  • A new, minimally invasive stenting technique for airway occlusions has been successfully developed.
  • This method offers a fast, inexpensive, and low-risk alternative for urgent stenting procedures.
  • The technique allows for easy placement and rotation of silicone stents, adaptable to various trachea sizes.
