To administer emergency oxygen, there are two primary methods depending on the casualty's consciousness and the required oxygen flow rate.
Administering Oxygen to a Conscious Casualty
If the casualty is conscious, there are two methods for oxygen administration:
- Low Flow Oxygen via Nasal Cannula:
- A nasal cannula (also known as nasal specs) is used to deliver low-flow oxygen.
- The oxygen flow rate should be between 1 and 6 liters per minute (L/min).
- This is a suitable method for individuals who need a smaller supplemental oxygen boost.
- High Flow Oxygen via Non-Rebreather Mask:
- A non-rebreather mask is used when a high flow of oxygen is required.
- This mask can deliver higher concentrations of oxygen than a nasal cannula.
| Method | Consciousness | Flow Rate | Use Case |
|---|---|---|---|
| Nasal Cannula | Conscious | 1-6 L/min | Low to moderate supplemental oxygen needs |
| Non-Rebreather Mask | Conscious | High Flow | High supplemental oxygen needs |
It's important to remember that this information is for emergency situations. For long-term oxygen administration, a healthcare provider should be consulted for proper guidance and management.
