Oxygen saturation is another element to consider in the evolution of COVID-19, so it is important to be aware of it and maintain contact with your doctor.
Oxygen saturation is a vital parameter to define the oxygen content in the blood and its release, and for this purpose, a pulse oximeter is used.
Normal blood oxygen levels range from 95 to 100 percent, so oxygen saturation levels should be 90 to 100 percent.
The Federal Consumer Protection Agency (Profeco) published what we should know about oxygen concentrators and medical oxygen cylinders in the February issue of Consumer Magazine.
When is an oxygen concentrator and a medical oxygen cylinder required?
Based on oxygen saturation levels and other symptoms, a doctor is the one who should indicate the use of a medical oxygen cylinder or an oxygen concentrator as a measure of external oxygen supplementation in the context of a disease such as COVID-19.
Is there any difference between them?
Oxygen concentrator
An oxygen concentrator is an electrical device that separates oxygen from ambient air, concentrates it, stores it, and takes air from the room and filters nitrogen. Therefore, the air supply never runs out, unlike oxygen tanks.
Furthermore, oxygen concentrators tend to vary the oxygen dose administered depending on the design or function of the device being used.
Medical oxygen cylinder
A medical oxygen cylinder is a cylindrical container designed to hold medical oxygen at high pressures in the form of compressed gas and must be refilled each time its content runs out.
Profeco recommends a hydrostatic test to determine if the cylinder has leaks, defects, or if it is in perfect condition to be refilled and to avoid acquiring tanks that are not valid.
Additionally, to avoid being a victim of fraud due to the scarcity of these devices during the COVID-19 pandemic, Profeco states that to identify a medical oxygen cylinder, it must have a green shoulder (Pantone 575 C), as well as labels describing its content.
The Consumer Magazine also issues a recommendation ensuring that "both the use of an oxygen concentrator and a medical oxygen cylinder must be prescribed by a doctor" and that these should not be replaced with "homemade inventions that will not work."
