A patient care system comprising an interface unit, a Patient Controlled Analgesia (PCA) unit, and a pulse oximetry unit is disclosed. The PCA unit provides PCA administration, including administration of a dose of analgesic upon request, and the pulse oximetry unit provides constant monitoring of the patient's blood oxygen saturation level and pulse rate. The interface unit provides for communication between and control of the PCA unit and the pulse oximetry unit, and further provides an interface between the user and the system. When the pulse oximetry unit indicates to the interface unit that the patient's blood oxygen saturation level and pulse rate has reached a user-specified minimum, the interface unit initiates visual and audio alarms and controls the PCA unit by shutting off the PCA unit. The interface unit also contains communication ports, which the interface unit can use to send signals to external devices, such as to alert alerts medical personnel.
