Answer:
Ask the casualty to describe the sensation of feeling in the limb.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Pulmonary circulation involves the transportation of deoxygenated blood from the right side of the mammalian heart directly to the lungs where oxygen is picked up by the blood and returns to the left side of the heart.
The pulmonary circulation loop is mainly supported (powered) by the right atrium and right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.
Hence, asking the casualty to describe the sensation of feeling in the limb is part of checking pulmonary circulation i.e the transportation of blood from the heart to the leg.
