With the contraction and diastole of the heart, the pulsation of the superficial arteries can be felt on the surface of the body and is called the pulse. Measuring the pulse involves observing the pulse rate, pulse rhythm, and the strength of the pulse. The pulse rate can reflect the number of beats per minute of the heart. Under normal circumstances, the pulse rate and the heart rate are the same, but under certain diseases, the pulse rate and the heart rate are not the same. 1, pulse measurement site: all superficial, near the bone of the large arteries can be measured pulse. The radial artery (thumb side at the wrist) is most often used, followed by the temporal artery, carotid artery, brachial artery, dorsalis pedis artery, etc. 2.Pulse measurement (radial artery as an example): the subject takes a comfortable lying position, the examiner presses the end of the index finger, middle finger and ring finger to the radial artery on the inner side of the subject’s wrist, and the finger pressure is appropriate to clearly touch the pulse. Generally, the normal pulse is measured for half a minute, and then multiplied by 2 for the number of pulses per minute. Abnormal pulses should be measured for at least one minute. If the pulse is too weak to touch, a stethoscope can be used to listen to the heart rate count. 3, the normal value of the pulse: normal adults in a quiet state pulse rate of 60 to 100 times per minute; 55 to 60 times per minute in the elderly; about 90 times per minute in children; up to 140 times per minute in newborns, the pulse should beat evenly and regularly strong. 4.Caution: Measure the pulse rate when the person being measured is quietly resting, and rest for 20 minutes after the activity before measuring. When measuring the pulse, not only count the number of pulse beats, but also pay attention to the rhythm of the pulse. Do not use the thumb to measure the pulse to prevent confusion between the thumb artery pulsation and the pulse.
