Various compensation mechanisms maintain cardiac output (some of these often aggravate the condition When the heart cannot maintain pumping capability: Cardiac output or stroke volume decreases Less blood reaches the various organs causing decreased cell function Fatigue and lethargy, mild acidosis develops Backup and congestion develop, as coronary demands for oxygen and glucose aren’t met Output from ventricle is less than inflow of blood Congestion in venous circulation draining to affected side of the heart Forward effects (similar with failure on either side) Decreased blood supply to tissue, general hypoxia Fatigue, weakness, dyspnea, shortness of breath Compensation mechanism Tachycardia, daytime oliguria Cutaneous and visceral vasoconstriction Back-up effects of left-sided failure Related to pulmonary congestion Dyspnea and orthopnea, cough Paroxysmal nocturnal dyspnea which indicates the presence of acute pulmonary edema Signs of right-sided failure and systemic backup Dependent edema in feet, legs or buttocks Increased pressure in jugular veins > distension Heptomegaly and Splenomegaly Ascites, acute right-sided failure Young Children with CHF Often secondary to congenital heart disease Feeding difficulties often the first sign because there’s a failure to gain weight or meet developmental guidelines Short sleep periods Tripod position to play Cough, rapid grunting respirations, flared nostrils, and wheezing Radiographs slow cardiomegaly Arterial blood gases are used to measure hypoxia

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
