Richard Levitan, a physician expert on patient oxygen levels treated patients at a New York Hospital, and found this very important fact about coronavirus and its attack on patient lungs. Early detection and treatment, use of pulse oximeter monitoring, are shown to be critical for coronavirus. Covid or cornavirus pneumonia is different from normal pneumonia in that it attacks the lungs but patients can be low on oxygen without realizing it through shortness of breath. As it turns out and confirmed by this physician expert who has invented intubation techniques and served at a New York hospital to understand why coronavirus was killing patients, the patient simply breathes faster and deeper without knowing it and is not short of breath even though his oxygen saturation is going down. This delays treatment- use of pulse oximeter is therefore recommended, an easy test placed on a finger that shows the oxygen reading. This kind of fast breathing then suddenly leads to the complete collapse of the patient's lungs, which is why so many end up in hospitals late and end up later on ventilators. British prime minister Boris Johnson received this kind of monitoring and early treatment to be able to return to work. ...
