Area of Science:
- Medical Sciences
- Respiratory Medicine
- Critical Care
Background:
- Respiratory problems are frequent reasons for hospital admission.
- Inadequate management of respiratory issues can lead to serious patient consequences.
- Effective respiratory support is vital in acute care settings.
Purpose of the Study:
- To identify indications and usage for various oxygen administration methods.
- To explain the theoretical basis of respiratory interventions.
- To provide a comprehensive overview of respiratory support strategies.
Main Methods:
- Discussion of normal breathing physiology.
- Explanation of respiratory failure mechanisms.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
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,...
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:
Administering Oxygen by Nasal Cannula
Nasal Cannulas
A nasal cannula is a lightweight tube split into two prongs placed in the nostrils, connected...

Oxygen Delivering System I: Nasal Cannula and Face Mask
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.
