Possibly he is: Retaining co2. If your dad has COPD and has been given a lot of supplemental oxygen in an effort to increase his oxygen saturation (spo2) he may not have enough respiratory drive to blow off the co2 independently and develop co2 narcosis causing him to be unresponsive. In these patients, we often use non-invasive positive pressure (bi-pap) to help patients as an alternative to mechanical vent.
