What do the rows of numbers on the bedside instrument of hospital patients mean? How normal is the numerical display?

This is an ECG monitor. On the right is the patient's heart rate, respiration, blood pressure and blood oxygen, and on the left is the corresponding waveform. The patient's condition in the intensive care unit is critical and may change at any time. ECG monitoring is the most intuitive and simple method to monitor the changes of patients' condition.

ECG monitor can monitor ECG, heart rate, blood pressure, respiration, fingertip oxygen saturation and fingertip pulse. The normal heart rate is 60~ 100, the normal respiration is 10-24, the normal blood pressure is 90~ 140, the diastolic blood pressure is 60~90, and the normal blood oxygen saturation is greater than 96%, which is a straight pulse.

The ECG monitor can set the alarm interval. When the alarm time limit is exceeded, the ECG monitor will give an alarm prompt. Under normal circumstances, the alarm interval set by ECG monitor is slightly wider than the normal range.
