-Patients may be confined to the hospital setting with an infectious
disease process or may develop one caused by the hospital environment.
-Therefore a basic understanding of these infectious disease processes
is useful in designing, implementing, and modifying physical therapy
treatment programs.

° Agent that is capable of producing antibodies when introduced into
a body of a susceptible person
ANTIGEN

person, either directly or indirectly
COMMUNICABLE
° Localized or systemic condition resulting from an adverse reaction
to the presence of an infectious agents(s) or its toxin(s); there must
be no evidence that the infection was present or incubating at the time of admission to the acute care setting

Both deliver air pressure when you breathe in and breathe out. But a BiPAP delivers higher
air pressure when you breathe in. The CPAP, on the other hand, delivers the same amount
of pressure at all times. So the BiPAP makes it easier to breathe out than the CPAP.
