Brief summary: Heart failure is a special clinical syndrome such as difficulty breathing, fatigue, and swollen legs characterized by increased JVP, crackle lung sounds, and peripheral edema caused by heart disorders both structural and/or functional, resulting in decreased cardiac output and increased intracardiac pressure at rest and activity. Body positioning has been shown to affect stroke volume and parasympathetic modulating activity. The right lateral 30" semifowler position is a very safe position in heart failure patients admitted to the ICU. Although body positioning can affect stroke volume, and parasympathetic modulation, it is not yet clear what effect it has on cardiac output
