A patient monitor is a medical device capable of continually checking, observing, and recording the vital signs of patients. These vital signs include:
- Blood Pressure
Physicians keep track of these vital signs when monitoring anesthetized or critical care patients.
A measure of the subtle voltage differences on the body surface around the heart to monitor the status of heart function. Heart rate is calculated from ECG in real-time.
- HR: Heart Rate
Non-Invasive Blood Pressure (NIBP)
The force that circulating blood exerts on the walls of the arteries.
- Systolic BP: Pressure during contraction of the heart
- Diastolic BP: Pressure during relaxation phase
- Mean BP: Systolic BP + 2 x Diastolic BP / 3
Pulse Oximetry (SpO2)
Pulse oximetry provides early information on problems in the delivery of oxygen to the tissue. Those problems may arise because of improper gas mixtures, blocked hoses or airways, inadequate ventilation, diffusion, or circulation.
- SaO2: Arterial Oxygen Saturation
- SpO2: Pulse Oximeter Saturation
