Description

Technical Field

[0001] The present invention relates to the technical field of monitors, and in particular to a combined heart monitor. Background Art

[0002] The monitor is mainly used to monitor the patient's vital signs, including electrocardiogram, blood pressure, blood oxygen saturation and respiration. The electrocardiogram is displayed as ECG, which records the changes in electrical activity generated by each cardiac cycle of the heart. The heart beats can also be seen. The normal range for adults is 60-100 beats / minute. The blood pressure is displayed as NIBP, which reflects the heart. The systolic pressure is in the front, and the normal range is 90-139mmHg, and the diastolic pressure is in the back. The normal range for adults is 60-89mmHg. Systolic pressure is also called high pressure, and diastolic pressure is also called low pressure. The blood oxygen saturation is displayed as SpO2, which reflects the concentration of blood oxygen in the blood and the volume ratio of oxygenated hemoglobin. The normal range is not less than 90%.
