CPAP/BiPAP Units

Airway pressure machines are available with two different modes of operation, namely standard CPAP and bilevel modes.  BiPAP is a proprietary name for one brand of bilevel unit.  CPAP units function at a fixed pressure during both inhaling and exhaling.  Bilevel units function with one pressure for inhaling, and a lower pressure for exhaling.  Many patients feel that bilevel therapy is a much more comfortable breathing mode, however bilevel units are more expensive.  Therefore most patients start with standard CPAP units.  Ask your physician if you are a candidate for bilevel therapy.  If you hare having trouble breathing with CPAP therapy, you may be eligible to upgrade to a bilevel unit.
