Hi Mark and others, thanks for sharing this info. Two questions:

1. When using the O2 concentrator, can we test for oxygen levels using Pulse Oximeter instead of capnometer? Looks like we need a prescription to buy a capnometer.

This paper finds that "During PSA in adults breathing room air, desaturation detectable by pulse oximeter usually occurs before overt changes in capnometry are identified." :

https://www.ncbi.nlm.nih.gov/pubmed/20880431

So, a pulse oximeter should suffice?

2. In the WHO report, they say: " About a quarter of severe and critical cases require mechanical ventilation while the remaining 75% require only oxygen supplementation. "

In the cases where only oxygen supplementation is indicated, will an O2 concentrator suffice, or do we need a Bipap as well?
