Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen01:16

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

978
Oxygen therapy is a pivotal aspect of medical care, particularly for patients with respiratory ailments. Two prominent oxygen-delivering systems include the Venturi mask and the transtracheal oxygen catheter.
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

Tracheostomy Decannulation01:21

Tracheostomy Decannulation

398
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...

Oxygen Delivering System III: Tracheostomy and T-piece

2.3K
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...

Tracheostomy Suctioning I: Pre-Procedural Steps

1.1K
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...

Tracheostomy Care I: Pre-procedural Steps

391
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 is a vital nursing procedure that involves removing secretions from the tracheostomy tube to maintain airway patency and prevent respiratory complications. Nurses need to understand the proper technique for tracheostomy suctioning to ensure patient safety and comfort. In this guide, we will outline the step-by-step process for performing tracheostomy suctioning, including preparing the sterile field, donning personal protective equipment (PPE), lubricating and connecting...

Area of Science:

  • Thoracic Surgery
  • Anesthesiology
  • Respiratory Physiology

Background:

  • Tracheal surgery, such as resection and anastomosis, typically requires conventional ventilation.
  • Maintaining adequate gas exchange during these procedures can be challenging.
  • Alternative methods to conventional ventilation are being explored to minimize physiological disruption.

Purpose of the Study:

  • To evaluate the feasibility, utility, and efficacy of apnoeic oxygenation during tracheal resection and anastomosis.
  • To assess apnoeic oxygenation as an alternative to conventional ventilation in tracheal surgeries.
  • To determine the impact of this technique on gas exchange and patient outcomes.

Main Methods:

  • Eight patients with tracheal stenosis underwent tracheal resection and anastomosis.
  • Preoperative bronchoscopic balloon dilation was performed to facilitate intubation.
  • Continuous oxygen at 5 L/min was delivered via an airway exchange catheter above the carina during anastomosis.
  • Gas exchange parameters (PaCO2, PaO2) were monitored during 15 minutes of apnoea.

Main Results:

  • Apnoeic oxygenation maintained adequate oxygenation (PaO2) without desaturation or hypoxic events in all patients.
  • A rise in PaCO2 and a slight decrease in PaO2 were observed over 15 minutes of apnoea.
  • Cross-field ventilation was not required in any of the cases.
  • The technique was found to be convenient, simple, and effective.

Conclusions:

  • Apnoeic oxygenation is a feasible and effective strategy during tracheal resection and anastomosis.
  • This technique offers a safe alternative to conventional ventilation, minimizing physiological disruption.
  • The method is simple to implement and maintain adequate oxygenation during critical surgical phases.
