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

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen

826
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,...

Mechanical Ventilation II: Invasive Ventilation01:23

Mechanical Ventilation II: Invasive Ventilation

209
Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

24
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

Administering Oxygen by Mask
Administering oxygen by mask is a common nursing intervention that provides supplemental oxygen to patients with respiratory distress or chronic lung conditions. This procedure involves delivering oxygen at a specified rate through a face mask connected to an oxygen source.
Equipment
The equipment necessary for this procedure includes:

Acute Respiratory Failure-V01:29

Acute Respiratory Failure-V

181
The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.
Ensure that patients are monitored continuously for their response to therapy, including changes in...

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

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure

303
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,...

Summary

An intensivist-led extracorporeal life support (ECLS) program successfully implemented venovenous (V-V), venoarterial (V-A), and extracorporeal cardiopulmonary resuscitation (ECPR) cannulations. Outcomes were comparable to literature, offering a model for other centers.

Area of Science:

  • Critical Care Medicine
  • Cardiopulmonary Support
  • Intensivist-Led Care

Background:

  • Extracorporeal life support (ECLS) requires specialized expertise for cannulation and management.
  • Developing ECLS programs often faces challenges related to subspecialty surgical availability.
  • Intensivist involvement in ECLS can potentially streamline care and improve outcomes.

Purpose of the Study:

  • To describe the development and outcomes of an intensivist-led adult ECLS program.
  • To evaluate the feasibility and safety of intensivist-performed ECLS cannulations (V-V, V-A, ECPR).
  • To establish a model for ECLS program implementation in resource-limited settings.

Main Methods:

  • Retrospective analysis of adult ECLS patients at University of New Mexico Hospital (February 2017–December 2021).
  • Data collection on cannulation types (V-V, V-A, ECPR), cannulation complications, and patient survival.
  • Comparison of outcomes across different ECLS modalities and patient cohorts (e.g., COVID-19 positive/negative).

Main Results:

  • 203 ECLS cannulations in 198 patients; 195 performed by intensivists with 9 complications.
  • Overall survival to discharge/transfer was 46.5%.
  • Survival rates varied: ECPR (32.3%), non-ECPR V-A (56%), V-V COVID-negative (66.7%), V-V COVID-positive (34.2%).

Conclusions:

  • An intensivist-led ECLS program can be successfully implemented, performing various cannulation types including ECPR.
  • Intensivist-performed ECLS demonstrated comparable outcomes to existing literature.
  • This program serves as a viable model for developing ECLS services, particularly where cardiothoracic surgical support is limited.
