As a medical device, the data on a cardiac monitor's display is crucial to understanding a patient's vital signs. The following is the interpretation of the main observation indicators:
Heart rate: usually located at the top of the screen, the normal range of 60 to 100 beats per minute, the higher the value represents the faster the heart rate. Blood pressure: This includes both systolic and diastolic blood pressure, with normal systolic blood pressure ranging from 90-140 mmHg and diastolic blood pressure ranging from 50-90 mmHg. For example, a blood pressure of 120/80 mmHg indicates that the blood pressure is in an ideal state. Oxygen saturation: usually between 90% and 100%, if it is lower than this range, it may indicate that the patient is hypoxic, the lower the value, the more severe the hypoxia. Respiratory rate: Normal values are between 16-22 breaths/minute, any deviation from this may require medical attention. Body temperature: below 37.3 ℃ is normal, more than this value may suggest that there is a fever, some of the monitor may not include temperature monitoring function.The role of the ECG monitor is to continuously monitor the patient's physiological parameters, and by comparing them with preset standards, detect abnormalities and issue alerts in time for the doctor to deal with them in a timely manner, to prevent complications, to help control the condition, and to ensure therapeutic efficacy. In addition, it can also monitor the situation before and after medication and surgery, providing comprehensive condition information support for healthcare professionals.
