NURS 412 Lecture Notes - Lecture 13: Pulse, Human Body Temperature, Bradycardia
Document Summary
After an incident ex. a fall. Difference between the heat p(cid:396)odu(cid:272)ed (cid:271)y the pe(cid:396)son"s (cid:271)ody and the heat lost (cid:271)y the pe(cid:396)son"s (cid:271)ody. Each time the heart beats, it sends a wave of blood through the arteries. Characteristics: pulse rate, pulse rhythm dysrhythmia, pulse amplitude. Where to check pulse: carotid, apical, apex of heart, brachial, radial. Inside of elbow: wrist thumb side, pedal, top of foot. Normal/abnormal pulse: 60-100bpm, tachycardia: elevated heartrate above 100, bradycardia: under a heartrate of 60. Normal process of breathing in and out. The force of the blood pushing against the arterial walls. Systolic pressure: top number: blood being forced out into systemic circulation, contraction of the heart, as soon as you hear a sound even if it"s (cid:395)uiet. Diastolic pressure: bottom number: ventricles are filling with blood from the atria, relaxing, when you stop hearing the noise. Difference between systolic and diastolic pressure (subtract the two) Resistance to blood flow: arteriosclerosis hardening of the arteries.
