Documentation of carotid pulse presence but the absence of radial pulse, the patient may be experiencing cardiogenic shock.

achieve this, the cardiovascular system is divided into two circuits- the pulmonary circuit and the systemic circuit. The pulmonary circuit consists of the heart, lungs and pulmonary veins and pulmonary arteries. This circuit’s role is to pump deoxygenated blood to from the heart to the lungs; it then becomes oxygenated blood and returns to the heart. It then pumps the oxygenated blood to the body’s tissues, muscles and organs which provides them with nutrients. Once the oxygenated blood has…
of cardiac operations are performed every day in hospitals varying in complexity to treat several lesions such as coronary artery bypass graft, heart valve replacement and total heart replacement.
