I'm not a doctor but I think there's multiple types of ventilation. There's invasive and non invasive ventilation. Invasive ventilation requires a tube inserted into you and it's very unpleasant. You are often sedated while this is done. Sedation requires monitoring and care to supply drugs, nutrition, cleaning, exercising and stretching muscles, and many more tasks. Noninvasive ventilation is like CPAP machines. They just cover your mouth. I don't know why you'd use one or another but there's likely a reason the sick are being sedated for covid-19
