What are the parameters monitored on vital sign monitors?

ECG, blood pressure, respiration and heart rate are the parameters displayed in most vital sign monitors. It is possible to add modules for oxygen saturation (SPO2), carbon dioxide in expired air (ETCO2 – endo tracheal CO2) and temperature. Blood pressure monitoring can be done non-invasively (cuff pressure) or non-invasively (within the artery). Central venous pressure is also monitored in most invasive monitors. Each one needs a separate sensor or transducer and an additional channel on the monitor. Sophisticated ECG monitoring can automatically detect ST segment elevation indicating myocardial ischemia and cardiac arrhythmia (disturbances in heart rhythm).
