Questions and Answers
Why is the nasal cannula ineffective when the patient's nose is blocked by blood or mucus?
Why is the nasal cannula ineffective when the patient's nose is blocked by blood or mucus?
- It causes discomfort to the patient
- It restricts the flow of atmospheric gas
- It reduces the concentration of inspired oxygen (correct)
- It causes CO2 accumulation in the mask
What is the maximum oxygen flow rate for a nasal cannula?
What is the maximum oxygen flow rate for a nasal cannula?
- 4 L per min (correct)
- 2 L per min
- 1 L per min
- 3 L per min
Why should the oxygen delivery through any face mask always exceed the minimum flow rate of 6L per min?
Why should the oxygen delivery through any face mask always exceed the minimum flow rate of 6L per min?
- To regulate the flow of atmospheric gas
- To ensure proper fitting of the mask
- To prevent CO2 accumulation in the mask (correct)
- To increase the patient's comfort

Study Notes
Nasal Cannula
- Ineffective when the patient's nose is blocked by blood or mucus due to obstructed oxygen flow
- Maximum oxygen flow rate is 6L per min
Face Masks
- Oxygen delivery should always exceed 6L per min to prevent rebreathing of carbon dioxide
- Simple face mask can deliver an oxygen concentration range of 40-60%
Venturi Mask
- Main benefit is precise oxygen concentration delivery
- Typically used in conditions requiring precise oxygen control, such as COPD
- Color-coded adapters attached to the Venturi mask indicate the corresponding oxygen concentration
- Advised for patients with COPD as it provides a precise oxygen concentration, which is crucial for these patients
Partial Rebreather Mask
- Using a flow rate above 10L per min can cause the mask to become a non-rebreather mask
- The portion of the patient's exhaled gas that enters the reservoir bag is rebreathed, allowing for some oxygen conservation
Non-Rebreather Mask
- Most often used in patients who require high oxygen concentrations and are at risk of respiratory failure
- The flutter valve assembly in the non-rebreather mask prevents exhaled gas from entering the reservoir bag
- To ensure proper functioning, paramedics should check the valve assembly and replace the oxygen reservoir bag regularly
