What is used to determine diastolic volume? EKG, EchoCardiogram, Xray? | Using ultrasound (high frequency echocardiogram) |
Stroke Volume = ___ - ___ =___? | Stroke Volume = EDV–ESV = 135 – 65 = 70ml/beat |
Cardiac Output-CO=___X___? | CO=HRxSV |
HR=___beats/min? | HR= (60-100bpm)or average 72 beats/min |
CO=___beats/min X ___ml/beat? | C.O. = avg. 72 beats/min X 70ml/beat |
Total CO=___L/min? | CO = 5000ml/min or 5L/min |
What is Preload? | Blood in the heart before contraction(Preload=Left Ventricular End Diastolic Volume)or the amount of stretch of the ventricle. |
When preload is increased what happens to stroke volume? | It increases |
What is Afterload? | The pressure that the left ventricle must overcome to eject blood to the body |
When afterload is increased what happens to stroke volume? | It decreases. The heart is pumping against higher pressure so less blood is pumped out. |
When afterload is decreased what happens to stroke volume? | It increases. |
