the respiratory therapist do to correct the problem?
a. replace the analyzer batteries
b. replace the electrolyte solution in the analyzer
c. tag the ventilator as non-functional and avoid placing it in service
d. change the fuel cell

following is most likely to increase nosocomial infection in a
hospital?
a. use of an HME for 48 hours
b. poor hand washing among staff
, c. frequent disconnection in the ventilator circuit
d. use of alcohol-based hand cleaners

patient receiving mechanical ventilation, the respiratory therapist
notices the low-pressure and low exhaled volume alarms are sounding.
Which of the following could be the cause?
a. kinked endotracheal tube
b. disconnected thermistor line
