Respiratory therapists are trained to work
with gases stored under pressure. Adherence to safety precautions and
regular maintenance and testing of equipment minimize the risk of injury. As
in many other health occupations, respiratory therapists are exposed to
infectious diseases, but by carefully following proper procedures they can
minimize the risks.
