The document discusses pulse examination. It defines pulse as a wave generated at the aorta and spreading along arterial walls due to heart pumping blood. Pulse is examined at superficial arteries like the radial artery. It is examined using three fingers to check rate, rhythm, volume, force, tension and equality on both sides. The condition of the vessel wall and peripheral pulsations are also examined. Apex pulse ratio can indicate cardiac arrhythmias if the heart rate and pulse rate are not equal.
