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 sensor configured to generate a signal in response to detecting the 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 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 sensor, wherein the audible alarm sounding device is operable to (i) produce an audible sound having a first frequency and a first tone in response to receiving the first control signal from the alarm processing circuit and (ii) produce an audible sound having a second frequency different from the first frequency and a second tone different from the first tone in response to receiving the second control signal from the alarm processing circuit, wherein the alarm system is configured to be operated by a caregiver to adjust the second tone between a number of different tones, 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. |
