This study compared two oxygen delivery systems in volunteers. Both systems performed similarly, but the nasal catheter was more cost-effective for oxygen therapy.
Area of Science:
- Respiratory Medicine
- Biomedical Engineering
Background:
- Oxygen delivery systems are crucial for patients requiring supplemental oxygen.
- Variable performance systems necessitate careful evaluation for clinical efficacy and cost-effectiveness.
Purpose of the Study:
- To compare the performance of two low-volume, variable performance oxygen delivery systems.
- To assess oropharyngeal oxygen concentrations during spontaneous breathing with nasal and mouth breathing.
- To determine the cost-effectiveness of the evaluated oxygen systems.
Main Methods:
- Conscious, spontaneously breathing volunteers participated in the study.
- Oropharyngeal oxygen concentrations were measured.
- Oxygen delivery systems were tested at flow rates of 2 and 4 litres/minute.
Main Results:
- Both oxygen delivery systems demonstrated similar performance under the tested conditions.
- No significant differences in oxygen delivery efficacy were noted between the systems.
- The nasal catheter was identified as the preferable option due to lower cost.
Conclusions:
- Low-volume, variable performance oxygen systems can provide comparable oxygen concentrations.
- Cost is a significant factor in selecting oxygen delivery devices.
- Nasal catheters represent a cost-effective choice for supplemental oxygen delivery in spontaneously breathing individuals.

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.

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,...
