Congestive Heart Failure: Left-sided vs Right-sided, Systolic vs Diastolic, Animation.

Congestive Heart Failure: Left-sided vs Right-sided, Systolic vs Diastolic, Animation.

Heart failure occurs when the heart is unable to provide sufficient blood to meet the body’s needs. Heart failure is not a disease on its own but rather a consequence of other underlying conditions. The impairment of the heart function can be due to an inability to PUMP effectively during systole, called SYSTOLIC heart failure, …

Compliance – decreased blood pressure | Circulatory system physiology | NCLEX-RN | Khan Academy

All right, I’m going to compare two individuals. One individual with very compliant blood vessels, and that person is going to be, as a result of the fact that they’re compliant, they’re going to be very happy. And then one person with very non-compliant vessels. And that person will be sad. And we also have …

Cardiac Output, Stroke volume, EDV, ESV, Ejection Fraction

Cardiac Output, Stroke volume, EDV, ESV, Ejection Fraction

CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, …
