Alarm Nurse Call Cables for Pulse Oximeters help to provide safe care to patients in many health care settings. These cable products connect the alarm output of the pulse oximeter to the hospital’s central station alarm monitoring system. The typical nurse call system input is located at the headwall jack near the patient bedside. A single headwall jack can be expanded to accommodate three alarmed devices with our Alarm Input Multiplier. This product accepts a pulse oximeter, patient monitor, ventilator, infusion pump, or similar medical device equipped with an alarm output.
