================================
The extra pressure from C-PAP allowed users to sleep by
keeping the airways open. The problem with C-PAP was that the
person had to exhale against the extra pressure. This made it
unsuitable for people suffering from neuromuscular diseases.With the development of BiPAP, air delivered through a mask
can be set at one pressure for inhaling and another for
exhaling. This makes BiPAP much easier for users to adapt to
and also allows neuromuscular disease sufferers to use the
device. Because of these dual settings, BiPAP allows people to
get more air in and out of the lungs without the natural
muscular effort needed to do so.
