Agreed. Need for ventilator is quite bad enough state for the human body. And it gets complicated further after intubation. Most patients have to be sedated to reduce the distress and anxiety caused by the endotracheal tube. Extubation is also a risky process and patient may have to be re-intubated when though they have recovered but stayed in for a recommended max period around 2 weeks and lungs got weak. When patient is on ventilator, it requires many control parameters to help a patient live longer - the sedatives have to be just right depending on the patient, antibiotics, secondary infection risks, intravenous needles risks, pre-existing illnesses, allergies, etc, etc, etc. All this assuming that the ventilator machines and peripherals are perfectly safe. On a large scale during a pandemic, there aren't just enough doctors, experienced nurses and heath care workers who that can deal with it. Engineers can build the ventilators, but the logistical part is still a nightmare.
