What is the role of a medical monitor?
A medical monitor is a device or system that measures and controls the physiological parameters of a patient, and can compare with the known set value, and if it exceeds the standard, it can send out an alarm device or system. The monitor must continuously monitor the physiological parameters of the patient for 24 hours, detect the trend of change, point out the critical situation, and provide the basis for emergency treatment and treatment by the doctor, so as to minimize the complications and achieve the purpose of alleviating and eliminating the condition. In addition to measuring and monitoring physiological parameters, the use of monitors also includes monitoring and processing medications and conditions before and after surgery.
In addition to measuring and monitoring physiological parameters, the use of monitors also includes monitoring and processing medications and conditions before and after surgery.
The standard 6 parameters of the monitor are ECG, respiration, non-invasive blood pressure, oxygen saturation, pulse, and body temperature. In addition, optional parameters include: invasive blood pressure, end-tidal carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output (invasive and non-invasive), EEG bispectral index and so on.
The scope of clinical application of the monitor: during operation, after operation, trauma care, coronary heart disease, critically ill patients, newborns, premature infants, hyperbaric oxygen chambers, delivery rooms, etc.
Instrument classification
According to the structure, it is divided into four categories: portable monitors, plug-in monitors, telemetry monitors, and HOLTER (24-hour dynamic electrocardiogram) ECG monitors.
According to their functions, they are divided into three categories: bedside monitors, central monitors, and outpatient monitors (telemetry monitors).
The bedside monitor is an instrument connected to the patient's bedside. It can continuously monitor various physiological parameters or certain states of the patient, and display alarms or records. It can also form a central monitor. Work as a whole.
The central monitor is also called the central system monitor. It is composed of a main monitor and several bedside monitors. The main monitor can control the work of each bedside monitor and monitor the conditions of multiple subjects at the same time. One of its important tasks is to complete the automatic recording of various abnormal physiological parameters and medical records.
The out-of-hospital monitor (telemetry monitor) is a small electronic monitor that the patient can carry with him. It can continuously monitor certain physiological parameters of the patient inside and outside the hospital for doctors to conduct non-real-time inspections.
