Does Nasal Cannula Design Affect Function?

A crossover comparison of four nasal cannulae shows differences in oxygen delivery and ETCO₂ measurement.

To assess whether the design of nasal cannulae influences O₂ delivery and detection of end tidal carbon dioxide (ETCO₂), researchers enrolled 45 healthy adults in a randomized, crossover study of four different nasal cannulae: bifurcated nasal prongs with both O₂ delivery and CO₂ sensing in each prong (Hudson), separate nasal prongs for O₂ delivery and CO₂ sensing (Salter), and nasal prongs with CO₂ sensing only and cloud delivery of O₂ via either multi-vents (Oridion) or dual vents (Medline). ETCO₂ and oxygen delivery (assessed by pharyngeal oxygen percentage and arterial blood gases) were measured for 2 minutes on room air and during supplemental O₂ delivery at 2, 4, and 6 liters per minute. The study was funded by the manufacturer of the…
