A simple face mask, also known as a simple oxygen mask, is used to deliver supplemental oxygen to patients who can breathe independently but require a higher oxygen concentration than the 21% found in the air.
Understanding Simple Face Masks
The simple face mask (SFM) is a basic, usually disposable, device made of clear plastic. It's designed to deliver oxygen therapy to patients experiencing respiratory issues requiring increased oxygen levels. Unlike more complex oxygen delivery systems, the SFM is relatively straightforward to use. However, it's crucial to ensure a proper seal between the mask and the patient's face for effective oxygen delivery. (Simple face mask - Wikipedia, Nasal Cannula or Oxygen Mask - CE/NCPD)
When to Use a Simple Face Mask:
- Supplemental Oxygen: When a patient needs more oxygen than is present in normal air (21%). This is determined by a healthcare professional based on the patient's condition and oxygen saturation levels. (When to use nasal cannula, a simple mask or a non-rebreathing ...)
- Mild to Moderate Hypoxia: The simple mask is suitable for patients experiencing mild to moderate low blood oxygen levels. The flow rate is usually kept below 5 L/min to avoid rebreathing excessive carbon dioxide. (Nasal Cannula or Oxygen Mask - CE/NCPD)
- Patient Can Breathe Independently: Crucially, the simple face mask is only for patients who can breathe on their own. Patients requiring mechanical ventilation will need a different type of respiratory support. (When to use nasal cannula, a simple mask or a non-rebreathing ...)
Important Considerations:
- Proper Fitting: Ensure a good seal to prevent oxygen leakage and ensure effective delivery.
- Oxygen Flow Rate: The flow rate is adjusted based on the patient's needs and medical advice. Generally, lower flow rates (below 5L/min) are used with simple masks to avoid CO2 buildup. (Nasal Cannula or Oxygen Mask - CE/NCPD, Guidelines on Oxygen and Oximetry - GGC Medicines)
- Communication: The mask can muffle speech, impacting communication.
