Nasal Cannula: Efficient Oxygen Delivery

1. Introduction to Nasal Cannula

Simple Oxygen Delivery:

Nasal cannulas are devices used for oxygen delivery to patients.
They connect to the constant flow outlet of an oxygen cylinder and have two small plastic prongs placed into the nostrils.

2. Oxygen Concentration Levels

Adjustable Concentrations:

Nasal cannulas provide oxygen at concentrations ranging from 24% to 44%, depending on factors like oxygen flow rate, the patient's nasal breathing, and speech.
Higher oxygen concentrations (over 30-35%) are generally challenging to achieve with nasal cannulas.

3. Suitability and Tolerance

Well-Tolerated and Limited Applicability:

Nasal cannulas are suitable for patients who can breathe freely through their nose and require a lower oxygen concentration.
They are generally well-tolerated and cause less discomfort compared to standard masks.
Not recommended for patients needing higher oxygen concentrations.

4. Maximum Flow Rate

Flow Rate and Oxygen Concentration:

For safe use, the maximum flow rate should not exceed 6 litres per minute, as higher rates can lead to discomfort and issues.

5. Flow Rate vs. Oxygen Concentration

Flow Rate and Corresponding Oxygen Concentrations:

1 litre per minute - 24%
2 litres per minute - 28%
3 litres per minute - 32%
4 litres per minute - 36%
5 litres per minute - 40%
6 litres per minute - 44%

6. Usage in Medical Settings

Application in Medical Care:

Nasal cannulas are typically not used in first aid or out-of-hospital emergency treatment as they cannot provide the higher oxygen concentrations often required in such situations.
