Oxygen Delivering System I: Nasal Cannula and Face Mask01:26

Oxygen Delivering System I: Nasal Cannula and Face Mask

1.1K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...

Administering Oxygen by Nasal Cannula

1.7K
Oxygen therapy is critical to patient care, especially for those struggling with respiratory issues. This intervention increases the oxygen concentration in the lungs, enhancing the amount of oxygen transported to the body's tissues. One standard method of delivering supplemental oxygen is through a nasal cannula, a non-invasive device that provides low to medium oxygen concentrations.

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

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

1.4K
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,...

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure01:16

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure

463
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...

Oxygen Delivering System III: Tracheostomy and T-piece

4.1K
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...

Physiological Control of Respiration01:23

Physiological Control of Respiration

5.3K
Introduction
Breathing, a seemingly passive process, is regulated by the respiratory center in the brainstem. This center coordinates the involuntary control of respirations, which means it occurs without conscious effort, ensuring a smooth and uninterrupted pattern.
Regulation of Ventilation
The body maintains ventilation by monitoring levels of carbon dioxide (CO2), oxygen (O2), and hydrogen ion concentration (pH) in the arterial blood. Among these factors, the level of CO2 plays a crucial...

Area of Science:

  • Respiratory Medicine
  • Biomedical Engineering
  • Clinical Technology

Background:

  • Oxygen administration is crucial for hypoxemic patients, but current clinical strategies are often suboptimal.
  • Effective oxygen titration aims to maintain target oxygen saturation levels ([Formula: see text] range).
  • Novel devices with closed-loop oxygen control offer potential for improved automated titration.

Purpose of the Study:

  • To evaluate the efficacy of a novel nasal high-flow device with closed-loop oxygen control.
  • To determine if closed-loop control can respond to desaturation and subsequent recovery in a controlled setting.
  • To provide proof-of-concept for automated oxygen titration in patients with chronic respiratory disease.

Main Methods:

  • A single-blind randomized crossover trial was conducted in adults with chronic respiratory disease.
  • Participants underwent a 6-minute walk test (6MWT) and a 10-min rest period.
  • Nasal high-flow was administered using room air, fixed 28% oxygen, or closed-loop titrated oxygen.

Main Results:

  • Closed-loop control maintained target [Formula: see text] (92-96%) for a significant portion of the 6MWT and recovery period.
  • Time in target saturation range was significantly greater with closed-loop control versus room air during 6MWT.
  • No significant difference in time within target range was observed between closed-loop and 28% oxygen during 6MWT, but it was superior during recovery.

Conclusions:

  • The novel nasal high-flow device with closed-loop control demonstrates proof-of-concept for responding to desaturation events.
  • Automated oxygen titration shows potential for optimizing oxygen therapy in patients experiencing exercise-induced desaturation.
  • This technology may offer a more effective strategy for managing hypoxemia in clinical practice.
