That happened to my sister-in-law. It's a very common story. Remdesivir and the vents do their job "well".
The worst that a vent could do is cause a pneumothorax or result in hypertension being maintained, possibly too little FIO2 or Oxygen, but most critical Patients receive 100% O2, and the Oxygen can easily be adjusted by Nurses or Physicians as O2 Sats are routinely monitored. Those are not good things, but it is not the Ventilators themselves doing the damage. Rather incompetence of their maintenance which is extraordinarily rare. I have never even seen it and can scarcely imagine it occurring.
Medications however, kill people everyday.
