Supplemental oxygen, exceeding atmospheric levels, is administered using various methods. The most common are nasal cannula, oxygen masks (simple, non-rebreather, Venturi), and integration into CPAP (Continuous Positive Airway Pressure) or BiPAP (Bilevel Positive Airway Pressure) machines.
Methods of Oxygen Delivery
- Nasal Cannula: This is a simple, comfortable device with two prongs placed in the nostrils. It delivers a low flow of oxygen. See American Lung Association's guide on home oxygen use for detailed instructions.
- Oxygen Masks: Several types exist, each providing different levels of oxygen concentration:
- Simple Mask: Delivers a moderate flow of oxygen.
- Non-Rebreather Mask: A reservoir bag allows for higher oxygen concentrations.
- Venturi Mask: Delivers a precise oxygen concentration.
- CPAP/BiPAP Machines: These machines deliver pressurized air, often with supplemental oxygen added, to assist breathing. These are used for patients with respiratory conditions.
Important Considerations
- Flow Rate: The amount of oxygen delivered is crucial and is determined by a healthcare professional based on the patient's needs. This often involves monitoring blood oxygen saturation (SpO2) levels. See the Royal Children's Hospital Melbourne guideline on oxygen delivery for further information.
- Safety: Proper training is essential for administering oxygen safely and effectively. Improper use can be dangerous. Always follow instructions from a healthcare professional. Note that even a single large tree can produce enough oxygen for several people. This is however not a method to deliver oxygen in medical settings.
- Medical Supervision: Oxygen therapy is a medical treatment requiring appropriate prescription and monitoring by healthcare professionals. This includes monitoring oxygen flow and device functionality.
