A nurse call system is an alarm service that patients or hospital staff activate by pressing a button on a bedside pendant, Patient Restrooms, or remotely from another room using buttons placed near the door of the patient’s room or via a nurse call pendant. The system allows patients to notify nurses and caregivers when they need assistance or are in pain. These systems could also be connected to Bed Pad Alarm, Smoke Detector Alarm and etc to alert nurses of emergencies or deteriorating conditions in patients.

While modern nurse call systems can have many different features and options, perhaps the most common main components of a nurse call system are Pillow speaker (or call light). This allows the patient to contact the nurse, as well as control the TV and overbed lights. Alternative breathe calls (for patients with limited movement or paralysis) can be plugged into the wall station; these let the patient contact the nurse simply by inhaling or exhaling into a particular tube. Wall station. This contains the microphone and speaker for communication between the nurse and patient. It also contains the code blue button and is the receptacle for the pillow speaker. IV pumps or ventilators can be connected to the nurse call station via the wall station, allowing alerts at the nurse's stations whenever the connected equipment goes into alarm. This notifies the nurse to any equipment alarms more quickly than otherwise possible. Bed cable. It allows the patient bed to be connected to the wall station. When the bed alarm is set, this allows the staff to know if a patient that shouldn’t exit the bed is attempting to exit. It can also allow a patient to call the nurse’s station via a button on the bed rail. Desk console. The desk console is like a telephone (and looks very similar to a telephone); it allows the unit secretary or nurse to answer call from the patient or call into the patient’s room.
