Test 5 PCW hw Flashcards
if PCW pressures are up then you have sampled
end expiration

RA goes up in resp variation during inspiration
kussmaul’s
respiratory variation in Ra indicates
Kussmaul’s
RAm 25 RVedp 15 PAd 25 PCWm 25
tamponade
95-100 means catheter is
wedged
60-70% means catheter is
in pa
70-95% catheter is
both pa and PCW
Why is the distance longer from the ECG R wave to the PCW v
wave than the distance from the ECG P wave to the PCW v wave?
Longer distance to travel backward from LV against Mitral
valve to LA to Pulmonary Veins and finally to catheter in PCW
position.
if PCW and LV events don’t align
phase shift
insertion pa to PCW is impossible
false
insertion PCW to la is impossible
true
to asses fro Pulmonary htn what waves to sample
PA and PCW

normal
if pressures are high for PCW respiratory variation when was it sampled
end expiration
proper scale for swan
40
PCWm=
LVedp=PAd=LA
In COPD, pulmonary artery diastolic pressure is lower than
pulmonary capillary wedge pressure
false
Papillary muscle rupture causes
MR canon v waves
In mitral regurgitation PCW a-waves are sometimes swamped by larger v-waves in fusion beats
true
PCWm>________in normal patients
RAm
PCW is elevated un tamponade
true
prominent c waves in PCW indicate
MS
In pulmonary hypertension PCW is elevated
false
how does pulmonary htn affect PCW
it doesn’t
gradient between PAd and PCWm
PE COPD
how could RAm exceeds PA
TS
increase in RA more than PA means
TS
what does MS do to waveforms
PCWm increase
what pressures are needed to asses MS
LV and PCW
PCW= 17 than repeat PCW=31 after 700 CC of saline and pt complains of SOB
pulmonary edema (decrease in EF)
what conditions increase end diastolic pa pressure and PCW
chronic obstructive lung disease
high cardiac output
which shock elevated PCw
cardiogenic shock
extreme difference between the peaks of the a
waves and their x descents?
CP?RC
CP is indicative of
discordance
RC is indicative of
Concordance
differences between RA and PCW tracings
v waves larger, sweep speed increased, respiratory variation in PCW
Increased RAv and RVs w decreased PAs PAd with PCW=PAd
PS+TR
diastolic gradient between RV and PA means
PS
RAv waves increased means
TR
Normal RA with, increased RVs RVedp and PAs with decreased PAd and PCW
PR
wide pulse pressure of the PA means
PR
increase in RA and RVs RVedp and PAs PAd with a decrease of PCWa with PCWm=PAd
MS
diastolic gradient between PAd and LV where PCWm=PAd means
MS
PCW canon v waves means
MR
dip and plateau and all pressures are elevating means
RC
increase in RA and RVs RVedp and PAs PAd PCWv with PCWm=PAd
MR
Increase in RAa RAv and PAs PAd and PCWa PCWv with decreased of RAx RAy and PCWx and PCWy with PCWm=PAd
