Patient Monitor

Overview

A multiparameter patient monitor continuously measures and displays a patient's vital signs at the bedside and alarms when any value leaves a set range. A single unit fuses several physiological measurements, electrocardiogram, oxygen saturation, blood pressure, temperature, respiration, and others, onto one screen and reports them to a central nursing station so one clinician can watch many beds.

Measurement is split across dedicated parameter modules behind the Parameter Acquisition Board, an isolated front-end that keeps every patient connection electrically separate from mains. The ECG Module amplifies the heart's biopotentials for rhythm and ST analysis, the SpO2 Module derives oxygen saturation from red and infrared light passed through a finger, and the NIBP Module inflates a cuff and reads systolic, diastolic, and mean pressure by the oscillometric method.

How it works

Further channels extend the picture: the IBP Module reads continuous invasive pressures from arterial or central lines through disposable transducers, the EtCO2 Capnography Module measures exhaled carbon dioxide by infrared capnography to confirm ventilation, while temperature and impedance-respiration modules round out the standard set. All module data is collected by the Main Board, which runs the alarm logic, trends, and the user interface.

Values and waveforms appear on the Display Assembly, a color touchscreen, and breaches drive the Alarm Unit with prioritized audible and visual signals. The Connectivity Board streams data over WiFi or Ethernet to a central station and the patient record, and the Power System runs the monitor from mains with a backup battery for transport. Patient leads land on the dedicated Ports Panel.
