PATIENT MONITOR

Patient Monitor / Medical Monitor• A patient monitor is a medical device used for monitoring the health status

of patients. • Patient monitors typically consist of 4 major components.

• Patient monitors are utilized in a wide range of inpatient and outpatient environments including conscious sedation, respiratory therapy, emergency medical services, and transport.

• Patient monitors are important because they can assist in providing for patient comfort and can reduce the risk of infection and other complications.

• Patient monitors have become vital to care in operating and emergency rooms, intensive care and critical care units.

Sensor Component Display device

Communication link

• Multimodal monitor includes of blood pressure and heart rate, also pulse oximetry and respiratory rate.

• Simultaneously measure and display the relevant vital parameters are commonly integrated into the bedside monitors in critical care units, and the anesthetic machines in operating rooms.

• These allow for continuous monitoring of a patient, with medical staff being continuously informed of the changes in general condition of a patient.

• Some monitors can even warn of pending fatal cardiac conditions before visible signs are noticeable to clinical staff.

Patient Monitor Components :

• Sensor - biosensors and mechanical sensors• Component - converting the signals from the sensors to a

format that can be shown on the display device or transferred to an external display or recording device.

• Display - CRT, LED or LCD screen• Communication link – several model are networkable• Mobile appliances – opened with mobile carried monitors
