An ECG monitor is an important piece of medical equipment used to monitor a patient's physiological state in real time. When we look at this data, the following indicators are particularly critical:
First, the heart rate is usually located at the top of the screen, with normal values ranging from 60 to 100 beats per minute (bpm). This value reflects the frequency of the heart's activity; if it's below 60 beats per minute, bradycardia may be present, and above 100 beats per minute it may indicate tachycardia.
Blood pressure is another important indicator, including systolic and diastolic blood pressure. Normal values for systolic blood pressure are 90 to 140 millimeters of mercury (mmHg), while diastolic blood pressure ranges from 50 to 90 mmHg. For example, 120/80 mmHg is the standard blood pressure range. If the value is abnormal, it may signal a problem with high or low blood pressure.
Blood oxygen saturation, which should normally be between 90 and 100 percent, represents the amount of oxygen in the blood. Below 90 percent may indicate that the patient is at risk for hypoxia and needs prompt treatment.
In addition, respiratory rate is often monitored, with a normal range of 16 to 22 breaths per minute. If it is outside this range, it may be associated with respiratory problems.
Temperature is monitored to see if the patient is febrile, and the normal value should be less than 37.3 degrees Celsius. A value higher than this means that fever may be present and requires attention and action by the doctor.
The role of the cardiac monitor is to detect any abnormal changes in time through continuous monitoring of these parameters so that the doctor can make accurate judgments and timely interventions to effectively prevent complications and assist in the treatment and management of the patient's health.
