Nurse-call systems are required for the maternity unit and the NICU and PICU. These
systems ensure communication between individual patients in their rooms and a centralized
location like the control desk. They also are used to communicate to staff from the
patient rooms or the entire unit. For emergencies, pull-string–activated call boxes are
located in the patient’s toilet rooms for activating the nurse-call system at the control
desk. For additional security, various areas of L&D install and integrate into the nursecall
system a video camera located at the entrance to the unit, which allows surveillance
of those requesting admittance.
