Question	Answer
Pulse Pressure	a. Systolic BP minus Diastolic BP b. Normal = 40 mmHg c. greater than 40 indicates decreased Stroke Volume (SV)
CO (Cardiac Output):	a. Heart Rate times SV b. Normal = 4.8 LPM c. More reliable than Mean Airway Pressure (MAP)
Define Preload	Blood that returns to ventricles at end diastolic, & refers to stretch of myocardial fibers after it is filled with blood.
Blood pressure	a. Normal Systolic = 90-140 b. Normal Diastolic = 60-90 c. As BP increases CO & CI usually decrease b. As BP decreases CO and CI usually increase
EF(Ejection Fraction):	a. % of blood volume pushed out of heart per beat. b. Normal = 65 – 75% c. Reduced with ventricular damage
PCWP (Pulmonary Capilary Wedge Pressure	1. Measures left heart function 2. Normal = 5 – 12 mmHg (same as PAP diastolic) 3. greater than 18 = edema forming in lungs (if no signs CHF think ARDS) 4. greater than 25 = edema in lungs from left heart failure (CHF) 5. greater t
CI (Cardiac Index):	a. Cardiac Output divided by Body Surface Area (BSA) b. Normal = 2.5 LPMm2 or simply CO/2 c. Decreased with shock, dehydration, cardiac fail, PE. d. Increased with hypoxia, low BP. e. More reliable measurement than CO.
MAP (Mean Arterial Pressure):	a. systolic BP + (Diastolic*2)/3 b. Normal = 70 – 105
SV (Stroke Volume):	a. Cardiac Output divided by Heart Rate b. Normal = 60 – 130 ml/beat c. It's the volume ejected per beat

Normal	a. Cardiac Output divided by Body Surface Area (BSA) b. _____ = 2.5 LPMm2 or simply CO/2 c. Decreased with shock, dehydration, cardiac fail, PE. d. Increased with hypoxia, low BP. e. More reliable measurement than CO.	7	1	true
Arterial	MAP (Mean _____ Pressure):	8	0	true
SV (Stroke Volume):	Answer: a. Cardiac Output divided by Heart Rate b. Normal = 60 – 130 ml/beat c. It's the volume ejected per beat	9	0	false
