Pulmonary Function Tests01:25

Pulmonary Function Tests

311
Pulmonary Function Tests (PFTs)
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
PFTs involve using a spirometer, a...

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

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

369
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,...

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

Oxygen Delivering System III: Tracheostomy and T-piece

516
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 II: Procedure01:23

Tracheostomy Suctioning II: Procedure

170
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...

Tracheostomy Care II: Procedure01:25

Tracheostomy Care II: Procedure

122
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...

Inhaled Medications01:23

Inhaled Medications

237
Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

Area of Science:

  • Pulmonology
  • Biomedical Engineering
  • Medical Device Design

Background:

  • Patients undergoing total laryngectomy (TL) often have smoking-related lung disease.
  • Standard spirometry requires oral breathing, posing a challenge for patients with tracheostomies.
  • Accurate lung function assessment is crucial for post-TL follow-up.

Purpose of the Study:

  • To develop and validate a novel device for spirometry testing in total laryngectomy patients.
  • To enable lung function assessment through a tracheostoma.

Main Methods:

  • A biocompatible, 3D-printed device was designed for hermetic connection between the spirometer and tracheostoma.
  • The device was tested on five patients who had undergone total laryngectomy.
  • Patient comfort, safety, and diagnostic validity were assessed.

Main Results:

  • The novel tracheostoma spirometry device was successfully used in five post-TL patients.
  • The device was found to be comfortable and safe for patients.
  • The results indicated the device is valid for diagnostic purposes.

Conclusions:

  • A 3D-printed device facilitates spirometry testing in total laryngectomy patients via their tracheostoma.
  • This innovation allows for essential lung function monitoring in a previously underserved patient group.
  • The device offers a comfortable, safe, and diagnostically valid solution for respiratory assessment post-TL.
