Test 3: Normal values/ How its Measured/ Use Flashcards
Mean arterial blood pressure (MAP)
70 - 100 mm Hg
MAP formula
(Systolic pressure + diastolic)/ 3
MAP is used to calculate
systemic vascular resistance; used in hemodynamic monitoring when giving vasoactive drugs
Normal Pulse pressure (systemic)
40 mm Hg
Pulse pressure (systemic) formula
systolic - diastolic
Pulse pressure (systemic) is used to
estimate the force of the pulse
Stroke volume (SV) range
60- 100 mL
SV formula
Q/heart rate
SV provides information about
cardiac performance
Cardiac index (CI) range
2.5- 4 L/min/m2
CI formula
Q body surface area (BSA
CI is important determinant of
cardiac performance (removes body size as a variable)
Stroke Index (SI) range
35- 55 mL/beat m2
SI formula
SV/BSA
SI is an important determinant of
cardiac performance (removes body size as a variable)
Systemic vascular resistance (SVR) range
900-1500 dyne x s x cm-5
SVR formula
([MAP-CVP]/CO) x 80
SVR is used to measure…..
And is useful in diagnosis of vascular problems
resistance in systemic circulation;
Pulmonary vascular resistance (PVR)
100- 250 dyne x s x cm-5
PVR formula
( [MPAP-PAOP]/Q) X 80
PVR is used to measure resistance in the….
And is useful in the diagnosis of pulmonary vascular problems
pulmonary vascular bed;
Mean pulmonary artery pressure (MPAP) range
10- 20 mm Hg
MPAP formula
pulmonary systolic pressure+ pulmonary diastolic pressure
MPAP is used to calculate
pulmonary vascular resistance
