The oxygen saturation of normal human arterial blood is 98%. If it is less than 94%, it is regarded as insufficient oxygen supply. In addition, normal people's pulse rate and heart rate are the same. Generally between 60-90 times per minute. However, in the event of exercise and stress, the heartbeat may increase.
