No. I know what I am talking about. As is deal with this for a living.
You state that SpO2 oxygen intake. There is no such thing. The oxygen intake for the human body on room air is 21%. The SPo2 is the oxygen saturation as measured by fast Fourier transformation comparing 480 nm to 440 nm absorbed light at the level of the capillary usually a finger tip or ear lob. This translates to the oxygenation saturation. Masks do not change the inspires level of oxygenation in the air. Air is made of 78% nitrogen and 21% oxygen with the remaining 1% carbon dioxide and other gases
You state unequivocally that there is a change in inspired oxygen concentration by using terms you are unfamiliar with and trying to convince people you have some expertise. It is glaringly obvious you don’t know the first thing about respiratory physiology
Your premise may be that wearing a mask reduces oxygen saturation in the blood stream 6% or so. That would be in generally unhealthy lungs with simple surgical masks. Even a six percent reduction in a healthy lung where the average saturation is 97-100 would not cause any significant issues as the steep part of the oxygen desaturation curve starts around 85% where small changes in alveolar oxygen produce large changes in arterial oxygen.
You can look this up in basic physiology books or basic respiratory units. I am not at odds with most medical professionals Becuase I am a medical expert in reapirstoeu physiology and practice it everyday
Next time get your facts straight before having your head handed to you from an knowledge stand point.
Since the medical profession recognizes that designation and there are numerous finger devises and apps the measure it, I assume you are a fraud.
So let it go and charge after someone else please mr troll
The actual facts are very simple and obvious. When you exhale into a mask the exhaled air has depleted oxygen content and increased CO2 content. When you inhale the next breath it is a mixture of fresh air and the previously exhaled air, with overall reduced oxygen content and increased CO2 content. This process continues with each breath, and after only a few breaths you are re-breathing significantly increased levels of CO2 and reduced levels of oxygen.
My personal experience: Many months ago I went to a grocery store shopping wearing a standard surgical mask. In about 15 minutes I began to feel unsteady, followed by tunnel vision and confusion. Immediately went outside and removed the mask, and fully recovered within 2 minutes.
Later, I experimented by measuring my SpO2 with a Pulse Oximeter without, and then with a mask. My normal SpO2 is about 96%, (without the mask) and dropped to as low as 81% within 15 minutes of wearing a standard (non fitted) surgical mask.
My solution: I now use an Airpro electric mask, which blows fresh filtered air into my mask, forcing out the exhaled CO2. Available on Amazon for less than $60. I can easily wear it for more than an hour without any CO2 poisoning symptoms.
