Structure and Design
● Consists of two soft prongs inserted into the nostrils and a light weight connecting tube.
● Designed for simplicity and comfort, secured behind the ears, allowing greater mobility for the patient.
● Covers both the nose and mouth, typically used for medium to high oxygen flow.
● Provides a more secure fit but can feel restrictive or uncomfortable for patients.
● Features dual channels: one for oxygen delivery and another connected to a CO₂ monitoring device.
● Includes ergonomic and comfortable designs for extended wear.
● Transparent tubing allows for easy observation.
Oxygen Delivery Efficiency
● Suitable for low-flow oxygen therapy (1-6 L/min) with oxygen concentrations ranging from 24% to 40%.
● Delivers oxygen in an open system, allowing mixing with room air.
● Provides medium to high oxygen flow (5-10 L/min) with concentrations of 40% to 60%.
● Certain types, like non-re-breather masks, can deliver nearly 100% oxygen.
● For low-flow oxygen therapy
Applications
Nasal Oxygen Cannula
● Best for stable patients with mild to moderate hypoxemia.
● Common in home care, general wards, or for patients needing mobility during therapy.
● Not ideal for high-concentration oxygen needs.
Oxygen Mask
● Suitable for emergency scenarios or patients with moderate to severe hypoxemia.
● Often used for short-term high-flow therapy.
ETCO₂/O₂ Nasal Cannulal
● Patients needing both oxygen therapy and CO2 monitoring.For simultaneous oxygen delivery and respiratory monitoring.
Comfort and Patient Experience
Nasal Oxygen Cannula
● Non-invasive, comfortable for long-term use.
● May cause nasal dryness or irritation but generally has minimal side effects.
Oxygen Mask
● Covers the face entirely, which can lead to discomfort or skin pressure sores.
● Prevents drinking, eating, or clear communication while in use.
ETCO₂/O₂ Nasal Cannula
● Non-invasive and designed for comfort, making it suitable for long-term use.
● Minimally impacts patients’ daily activities and mobility.
The choice between these devices depends on the patient’s oxygen needs, comfort, and specific medical situation. For low-flow oxygen therapy and mobility, nasal oxygen cannulas are most common. Oxygen masks are preferred for higher flow or emergency situations, while ETCO₂/O₂ nasal catheters are Best for patients requiring dual-purpose therapy (oxygen + respiratory monitoring) in critical care, anesthesia, or post-operative settings.
