A ventilator always requires intubation Can you elaborate? This ventilator documentation[0] says for invasive and noninvasive ventilation [0] https://www.usa.

  Many vents can also operate in BiPAP or CPAP modes or as pure demand O2 supplies for people who can still breathe. That can be done with a mask.

  When treating bilateral interstitial pneumonia, you're almost always intubating. Patients presenting BIP require higher oxygenation than a CPAP style mask can provide. Using a limited availability ventilator with just a mask is a waste at this time.
