A patient monitor is a medical device used in hospitals and clinics to continuously measure and display a patient’s vital signs in real time. It helps healthcare providers keep track of a patient’s health condition and respond quickly if something changes.
Patient monitors track important body functions such as:
-
Heart Rate (HR) — how fast the heart beats
-
Blood Pressure (BP) — force of blood in the arteries
-
Oxygen Saturation (SpO₂) — amount of oxygen in the blood
-
Respiratory Rate (RR) — how many breaths per minute
-
Temperature — body heat level
-
ECG (Electrocardiogram) — heart’s electrical activity (on multi-parameter models)
