Claim Text:
1. A patient care apparatus comprising: an alarm system, comprising: an event detection sensor for monitoring the condition of the patient care apparatus; an audible alarm sounding device operable to produce audible sounds; a non-contact volume reduction sensor configured to generate a signal in response to detecting a caregiver; a user interface operable to display visual information about the alarm system; and an alarm processing circuit configured to receive signals from the event detection sensor and the non-contact volume reduction sensor, generate a first control signal based on the signals from the event detection sensor, and generate a second control signal when the signal is received from the non-contract volume reduction sensor, wherein the audible alarm sounding device is operable to (i) produce an audible sound at a first predefined volume in response to receiving the first control signal from the alarm processing circuit and (ii) produce an audible sound at a second predefined volume in response to receiving the second control signal from the alarm processing circuit, wherein the alarm system is configured to be operated by the caregiver to adjust the second predefined volume between a number of different levels, and wherein the user interface is operable to (i) display a first visual alarm in response to receiving the first control signal from the alarm processing circuit and (ii) display a second visual alarm in response to receiving the second control signal from the alarm processing circuit, the second visual alarm being different from the first visual alarm.
