In order to get adequate pressure from my F & P 405 Flexfit mask, I have upped the pressure to 11.
A pressure of 8 seems adequate with the Swift mask.
I was told by 2 different companies that they do not check their competitor's products to see how they perform with their machines which is not a good thing as far as the consumer is concerned.
I am using a Remstar Pro w/cflex.
I don't know anything about manometers. I am wondering if there is any mechanical way to check the pressures of different masks to see if they are functioning at the proper pressure? Could the DME do this?
