imped value in medicine is the meaning of cardiac monitor. The relevant content is as follows:
One, the instrument
Mainly an instrument that can continuously measure the patient's physiological parameters. Cardiac monitor itself does not have a normal value, its measurement of important indicators have a certain normal range, such as respiratory rate in 12-20 times / min, normal human blood pressure systolic blood pressure in the 90-139mmHg, diastolic blood pressure in the 60-89mmHg, oxygen saturation can not be lower than 90%, the pulse should be fluctuating in the 60-100 times / min.
Second, the application
Cardiac monitor in the medical clinic is widely used, in the past is mainly used for the monitoring of critically ill patients, has been applied to the general ward monitoring, and even at the grass-roots level as well as the community medical units, but also gradually carry out the use.
Cardiac monitors are currently used in the clinical range of perioperative, preoperative, intraoperative and postoperative. In addition, like the surgical ICU for the treatment and care of critically ill patients also need to use cardiac monitors, commonly used in internal medicine in coronary heart disease, myocardial infarction critically ill patients in the population, suffering from severe respiratory diseases, the need to clarify the patient's oxygenation, but also need cardiac monitors.
In addition, in neonatal and pediatric applications are also more widely used, for newborns, premature infants, etc., also need to carry out continuous cardiac monitoring.
The ECG monitor is a non-invasive monitoring device, which is connected to the chest wall of the body through electrodes and electrodes, and is able to monitor the more important physiological parameters of the human body, as well as vital signs. In addition, the parameters can be selected from end-expiratory carbon dioxide, invasive blood pressure, respiratory mechanics, cardiac output and other indicators, which can better monitor the patient's condition.
Four, the role
The most common monitor that the bedside cardiac monitor, is set up in the bedside, and the patient is connected to the instrument, the patient's various physiological parameters or some state of continuous monitoring, to be displayed on the alarm or record. The parameters of ECG monitor have reference value in the clinic, and doctors can carry out timely treatment according to the prompts of ECG monitor.
1, ECG: that is, the cardiac waveform, through the cardiac waveform monitoring to determine whether the arrhythmia, as well as to monitor the heart rate of fast and slow changes;
2, HR: that is, the heart rate, the normal heart rate of 60-100 beats / minute;
3, RR: represents the respiratory rate, the normal value of the general in the 12-20 times / minute;
4, SpO2: represents the blood oxygen saturation, the normal range is 95%-100%;
5. NIBP: represents the non-invasive blood pressure, the normal range of systolic blood pressure is 90-139mmHg, the normal range of diastolic blood pressure is 60-89mmHg.
During the operation, after the operation, trauma care, coronary artery disease, critically ill, newborn babies, maternity, etc., all can be The use of cardiac monitors to assist in the diagnosis and treatment. Cardiac monitors can generally set their own alarm boundaries for monitoring parameters according to the patient's condition, and will alert if the boundaries are exceeded.
