Under typical conditions, the only cleaning the manual
sphygmomanometer requires is a wiping down with a liquid disinfection
agent. However, if further disinfection is required, remove the
sphygmomanometer gauge assembly, hoses, and blood pressure cuff from
the anesthesia machine and sterilize them with ethylene oxide gas (cold
cycle), followed by appropriate aeration according to the sterilizer
manufacturer's instructions.
NOTE: Do not autoclave the gauge assembly; it cannot withstand the
heat of autoclaving.
