Abstract
A data acquisition device is disclosed for use in a patient monitoring system which includes a display device. The system also includes a pressure transducer which produces patient blood pressure signals. The data acquisition device includes terminals for receiving signals representing blood pressure from the pressure transducer. Circuitry in the data acquisition device, including multiplexers and a digital to analog converter conditions the signals representing blood pressure. The pressure transducer and the circuitry are collocated. The device also includes circuit paths for electrically coupling the pressure transducer and the conditioning circuitry. The conditioning circuitry is selectably coupled to the display to provide the conditioned signals to the display. The data acquisition device may be positioned independently of the display device.
