I don't think the vital sign readings were done on a patient in ICU or on ventilation. My guess is they were done on a person with very healthy lungs (hence the Oxygen saturation of 100%) and who had higher than normal blood pressure with a fast heart rate. Maybe someone who is normally hypertensive and for whatever reason is under stress, or feeling pain.As someone who sells medical ventilators to hospitals and services them since 13+ years I can tell you that ventilating somebody with 100% more than 15 minutes is the quickest way to destroy their lungs, or so I am told by my doctor users/clients. If the situation requires 100% saturation it is done for short periods of time like 15 mins at a time, but NOT continuously. A few hours on 100% and the patient's lungs are done. For respiration support you put patients on 21 to max 30% oxygen with the ventilator in the spontaneous breathing mode with pressure (or volume) support. You will never see patients under ventilator with 100% oxygen saturation for extended periods of time. My ventilators even have a visual and audio warning if you set them to 100% for longer than a few minutes. So, this looks like a propaganda showcase to me.
Respiratory nursing and ICU nursing is not my area of expertise, however, as far as respirators are concerned, I believe there are two types of respiratory support - invasive and non-invasive. The invasive one would require putting the patient to sleep in order to overcome their gag reflex and putting 'an airway' down their throat. In both circumstances you'd want an trained operator to work the machines, otherwise, yeah, you'd destroy the lungs! Not good at all!!! And highly risky to the patient!
