Can Decreased Cardiac Output Cause Somebody Delirium
We believe delirium occurs when the brain cannot maintain its normal activities when overwhelmed by metabolic demands or other variables which exceed the brain's capacity to compensate for. Brains with less reserve capacity are particularly vulnerable. Not entirely unlike acute heart failure. See my last textbook chapter for more reading in the appi textbook ...Read more
Overloading: Low cardiac function may not be able to keep up with too much volume and the fluid backs up in places like the lung, neck, abdomen, and legs. Too much volume can overwhelm a borderline heart already weak. When the heart cannot keep up the needed cardiac output (liters per min) and making the pump work harder increasing pressure inside the heart, and dilating the chamber getting into a bad cycle. ...Read moreSee 1 more doctor answer
Stroke volume: Cardiac output is determined by heart rate and volume of blood pumped by heart in each heartbeat (stroke volume). Increased fluid volume increases the stroke volume and therefore cardiac output. Decreased fluid volume decreases the stroke volume and therefore cardiac output. ...Read moreSee 1 more doctor answer
Hypertension: High blood pressure usually implies an increased peripheral vascular resistance for a time the heart can keep up with the resistance late in the course the heart begins to not be able to generate the stroke volume against the resistance and cardiac output may fall. If abnormal ventricular function is present, cardiac output may fall earlier. ...Read moreSee 1 more doctor answer
Complicated.: It is an indirect relationship. Hypertension over time can lead to changes in the heart muscle and heart function. It may eventually lead to heart failure. When this ensues the output of the heart can eventually decline and cause serious symptoms. In the earlier stages if hypertension cardiac output actually goes up. ...Read moreSee 1 more doctor answer
Sick muscle: The heart is supposed to pump out a certain amount with every heart beat, if that amount is too low, e.g. Low out put, the heart muscle is too weak to do it's job(failure). ...Read more
