Abstract: A physiological function monitor module is provided. The module comprises a physiological function rate detector circuit adapted to receive an input from a patient and convert the same to a DC voltage output signal proportional to the rate of the physiological function of the patient under consideration. The module further includes an alarm generator connected to the output of the detector circuit. The alarm generator includes means for comparing the DC voltage level of the detector circuit to a preselected level and for generating an alarm signal in the event the DC level deviates beyond permissible bounds from the preset level. The module also includes a digital display and an analog/digital converter connected to the output of the detector circuit in driving relationship with the digital display. A character generator is connected to the output of the alarm generator and is also connected in driving relationship to the digital display in parallel with the analog/digital converter.
