how do we measure preload of the right sided heart? -
Answer-CVP
CVP normal range - Answer-2-6
what is needed to transduce CVP? - Answer-central line
CVP - Answer-the pressure in the central veins (SVC) that
reflects the blood volume and the right side of the heart's
ability to pump blood
how do we measure preload in the left sided heart? -
Answer-1. PAD (pulmonary artery diastolic)
2. PAWP (pulmonary artery wedge pressure)
what is needed to transduce PADP/PAWP? - Answer-
swan/PA catheter
,2|Page
normal range of PADP - Answer-8-12
normal range of PAP (pulmonary artery pressure) -
Answer-25/10
equation for cardiac output - Answer-HR x SV
what factors affect stroke volume - Answer-1. preload
2. afterload
3. contractility
DO2 - Answer-O2 delivery to tissues
main effect of tachycardia - Answer-not enough filling time
(decreased filling pressure) --> decreased SV
main effect of bradycardia - Answer-low DO2 --> increased
lactic as cells switch to anaerobic respiration
preload - Answer-the stretch of the ventricles at the end of
diastole
, 3|Page
contractility - Answer-the ability of the heart muscle to
contract to generate force to pump blood
afterload - Answer-the resistance the heart must overcome
to eject blood during systole
SVI-NICOM - Answer-Stroke Volume Index - Non-invasive
Cardiac Output Monitoring
what does SVI-NICOM delta >10% mean? - Answer-pt. is
fluid responsive
what does SVI-NICOM delta 0-10% mean? - Answer-gray
area
what does SVI-NICOM delta <0% mean? - Answer-pt. is
not fluid responsive
what should your mind go to when thinking of how to treat
low preload? - Answer-pt. needs volume
crystalloids (NS, LR, D5)
