Document Summary
Use the apical pulse when taking the pulse rate of an infant. When you auscultate the apical rate, the lubb-dubb you hear represents one cardiac cycle or heartbeat. You will auscultate (listen for sounds within the body to evaluate the condition of heart, lungs, pleura, intestines, or other organs or to detect fetal heart tones) bowel, lung, and heart sounds using diaphragm. Blood pressure is the pressure exerted by the circulating volume of blood on the arterial walls, the veins, and the chambers of the heart. Blood pressure is measured in millimeters of mercury (mm hg) The condition of the heart and the patient"s age, sex, emotional state, size, temperature, and amount of physical activity can influence the pulse rate. If the pulse rate is slower than 60 beats per minute, the person has bradycardia. One cause of bradycardia is unrelieved severe pain; pain stimulates the parasympathetic nervous system, which slows the heart rate.
