Test 4 PA notes Flashcards
RVs=
PAs
does pa have respiratory variation
slight
increase in RA a/v/m in which RAm exceeds RVedp suggests
TS
PCW is the same as
LA
hypotension, PS, PA stenosis, epstein’s, TS, tricuspid atresia cause what to PA
PAs decrease
wide pulse pressure suggests
PR
during dicrotic notch what occurs
PV closes
PA normal measures
s/d/m 25-30/10-15/10-19
equalizing and elevation of pressures suggest
tamponade
a-v stenosis shows as what
diastolic gradient
PCWm =
PAd
PVC pressure readings indicate you are in the
ventricle
PAm>20mmhg
pulmonary htn (mild 20 moderate 35 severe 45)
when is PA measured
end expiratory
what Cath is used for pa measurements
swan
PAs/d/m exceeds LV/AO pressures this suggests
pulmonary hypertension
RA ischemia, RV infarct, PE, Tamponade cause what
reduced pulse pressure
dicrotic notch marks the start of
isovolumetric relaxation
semilunar regurge shows as
wide pulse pressure
absence of a dicrotic notch suggests
PR
semilunar stenosis shows as what
systolic gradient
Increased PA pressures suggests
pulmonary disease (COPD/PE)
Increase in PAs causing a large difference with PAd suggests
PR (wide pulse pressure)
pulmonary htn, MS, MR, CHF RC, VSD, pulmonary disease cause what to PA
PAs increase
