Deoxygenated blood from the systemic veins flows
|
Through the right heart in to the pulmonary circulation
|
|
Oxygenated blood from the pulmonary veins flow
|
Through the left heart into the systemic circulation
|
|
Right and left heart must maintain
|
An equal cardiac out put
|
|
Cardiac output
|
The amount of blood the heart pumps each minute
|
|
Cardiac output
|
Heart rate x stroke volume
|
|
Heart rate beats every minute and is regulated by a balance between the activity of the
|
Sympathetic nervous system (increases heart, and the parasympathetic nervous system (slow the heart rate)
|
|
Stroke volume
|
How much blood the heart pump with each
beat, a function of preload, after load and cardiac contractility
|
|
Right heart failure
|
Is failure of the right heart to pump blood into the pulmonary circulation.
|
|
What happens in right side heart failure
|
Blood back up in the systemic circulation,
and causes peripheral edema and congestion of abdominal organs
|
|
What is left side heart failure
|
Failure of the left heart to pump blood into the systemic circulation
|
|
What happens in left sided heart failure
|
Blood backs up in the pulmonary circulation, and causes pulmonary edema
|
|
What is systolic failure
|
Impaired ejection - increased end systolic
volume, and or diastolic failure impaired filling - decreased
|
|
Causes if systolic failure
|
Impaired function of excessive work demands, high output failure uncommon- excessive demands or low output
|
|
List 4 impaired cardiac function related to myocardial disease
|
Cardiomyopathies, myocarditis, coronary insufficiency, and myocardial infarction
|
|
List 3 excess work demands in relation to increased pressure work.
|
Systemic hypertension, pulmonary hypertension, and coarctation of the aorta.
