Question

Can you explain the characteristics/differences between left-sided heart failure and right-sided heart failure. How do these conditions affect efficient oxygenation?

Condition	Characteristics	Effects on oxygenation

Answer 1

Heart fail ure is the inability of the ventricles to fill or pump enough to meet the body's oxygen & requirements. " his caused by coronary artery disease, cardiomyopathi , heart valve problems & hypertension. bodys oxygen & nutrient - It is of two types: 1x Right sided HE il Left sided HF- characteristics : characteristics it is characterised it is characterized by . by the presence Pulmonary edema of peripheral edena Pulmonary congestion is due to elevation caused due to inadequate! in peripheral pumping of blood, the blood. venous pressure. backs up in the blood · Raised jugular vessels of the lung As. Ivein pressure blood backs up in the caused by lungs pressure in the increase jugular veins of the lungs increases. vein distention tachycardia due to & hypotension due rapid production of to failure to electrical signals. adapt acutely & Third heart Sound results in rapid It is caused by a right ventricular sudden deceleration of

Right sided HF chion & dystunction congestive hepatomegals left atriun Left Sided HE. blood How into the left ventricle from the in the * cardiomegaly. It is due to back-up flow of blood liver which results Seen due to enlarged in ischemic liver. left ventricle. effect on oxygenation effect on oxygenation : - Dyspnea occurs - Tachypnea is noted due to redistribution due to back flow of of fluid from blood into the lungs Asplanchnic circulation & that causes Lower extremities f shortness of breath that leads to & build up of thuid. Increase in pulmonary capillary pressure

I by Stenosis Regurgitation In this valve valve doesnt clase doesn't open all all the way so blood the way , not leaks backward. enough blood passess through 1 It is characterized -> It is characterized bye obstruction of - backward flow due forward flow to incomplete valve restricting valve closure opening - dyspnea. shortness of breath -endocarditis Fatigue, dizziness - fatigue swollen feet or legs - orthopnea Heast palpitation's - palpitation. chest discomfort effect on effect on oxygenation oxygenation - Dyspnea Tachypnea.
