The simple act of wearing a mask amid the ongoing COVID-19 pandemic has become a politically charged topic in the U.S. and across social media. Despite the urgings of public health officials and pleas from doctors in hard-hit hospitals across the country, some people have still refused to don a facial covering, citing widespread disinformation about alleged negative health effects of mask wearing.
One Irish doctor set out to prove mask detractors wrong in an experiment that debunked the claim that wearing a facial covering negatively impacts the wearer’s oxygen levels.
Dr. Maitiu O Tuathail, a doctor based in Dublin, shared on Twitter that patients repeatedly ask him whether masks affect oxygen levels.
He conducted the test in response to the queries, and he found that the results did not show a lowering of oxygen levels.
The video, posted Tuesday, showed O Tuathail putting six face masks on his face as he recorded his pulse rate on a pulse oximeter.The pulse oximeter showed no change in the doctor’s oxygen levels after putting on the medical coverings.
He’s not an engineer. I can prove beyond any shadow of a doubt that an increased ΔP causes a decrease in flow rate (Q) unless you’re dealing with a positive displacement pump operating short of “dead head” conditions.
With his brain controlling his lungs and diaphragm, he has a PD pump. He simply breathed enough to compensate for the increased differential pressure. But humans get fatigued, and there is no study demonstrating that there wouldn’t have been a decrease in O2 saturation levels over time, or that less healthy individuals wouldn’t have suffered.
This should be placed in the category of fake science. It’s just entertainment. Get a team to study it, and then get a PE seal and signature on it. Then maybe I’ll take it seriously. Otherwise, it’s just a circus trick suitable for a carnival. It’s the equivalent of the bearded fat lady lifting a thousand pounds over her head.
