Oxygen Mask Mold-Working Properties Of Simple Mask
Simple Mask (SFM) is a basic disposable mask made of transparent plastic that provides oxygen treatment for patients with chest pain (possible heart disease), dizziness, and minor bleeding. The mask is only suitable for patients who are able to breathe on their own but may require a higher oxygen concentration than the 21% oxygen concentration in the surrounding air. Patients who are unable to breathe by themselves switch to a medical ventilator. For FiO2 with an oxygen content of 40-60%, a simple mask can provide a higher flow rate (6-10 liters per minute) than a nasal catheter. Nasal cannula and simple mask are described as a low flow delivery system.
Unlike non-respirator and partial rebreather masks, simple masks do not have storage bags. It also has holes in the mask, instead of the non-respiratory check valve, so ambient air can enter the mask. This feature eliminates the risk of suffocation if the mask with check valve is disconnected from oxygen. Therefore, simple masks are often the first choice for basic life support personnel (such as firefighters, lifeguards, and other non-medical rescue personnel) who have been trained in basic first aid.
The final oxygen concentration delivered by a simple mask depends on the amount of room air mixed with the oxygen that the patient is breathing. Air mixing depends on the amount of air everyone is breathing at the moment and the fit of the mask. Due to the variability of these factors, the final oxygen concentration is somewhat uncontrolled. A venturi device attached to the mask can be used to control the concentration of oxygen delivered to some extent. Generally, it is used to prevent hypoxia in patients with emphysema who have lost their ability to fully inhale. Although more clinically useful data can be obtained by extracting arterial blood gas, the effectiveness of treatment can be continuously monitored using pulse oximetry.
