pulmonary hypertension Flashcards
(37 cards)
a map >__ is needed to maintin good adequate perfusion
60
how do we calculate map
(systolic+ (2* diastolic)/3
map <60 means what
inadequate perfusion is likely
what is the MAP of a bp that is 120/80
MAP
120+ (2*80)/3
first do 2*80= 160
then add 160+120
280/3
93.3= good adequate perfusion to the organs
normal mean pulmonary arterial pressure (mPAP) is between _______
8-20 mmhg
what is the definitive way to test pulmonary arterial pressure
pulmonary artery catheterization is the definitive way to determine the diagnosis of pulmonary hypertension
how is pulmonary artery catheterization done
the pulmonary artery catheter
inserted in the right atrium from venous access usually through the right internal jugular vein
pulmonary hypertension is diagnosed if mPAP is >__ mmhm
20
if pulmonary hypertension is greater then __ indicates severe pulmonary HTN
35
what disorders fall under group 1 pulmonary HTN
idiopathic PH
HIV
LUPUS
CT disorders
congenital heart disease
what disorder falls under group 2 pulmonary HTN
left heart diseases
aortic stenosis
left ventricular systolic/diastolic dysfunction
what disorders fall under group 3 pulmonary HTN
COPD
obstructive sleep apnea
interstitial lung disease
pulmonary fibrosis
what disorders fall under group 4 pulmonary HTN
thromboembolic disorders PE
what disprders fall under group 5 pulmonary HTN
all other diseases
kidney
sarcoid
most common group that causes pulmonary HTN
left heart disease
- aortic stenosis
left ventricular hypertrophy
if pulmonary arterial wedge pressure is greater than (>15) then this signifies _______
left heart disease
group 2
pulmonary arterial wedge pressure estimates pressure of _____
left atrium
if pulmonary wedge pressure is <15 then this means pulmonary HTN could be due to what?
thromboembolic disorder (4)
copd/lung (3)
arterial resistance (1)
pulmonary HTN signs
early on= shortness of breath and dyspnea
advancing disease it will lead more to exertional dyspnea
other
- jvd
ascites
pulmonary htn ekg findings
right ventricular hyprtrophy
—–> tall R wave, in V1
right ventricular strain——> ST depression with T wave inversion, v1-v3
right axis deviation
1 is down, avf is up
gold standard test for pulmonary HTN (most precise)
right heart catheterization
>20 mpap is diagnostic
other lab work to check in pulmonsry HTN
check for HIV
check LFTs
- for chronic liver disease
check anti nuclear antibody to screen for rheumatoid factor
chest x ray for pulmonary HTN shows ______
loss of AP window
group 4 class i lowest prevalence but those with hisotry of a PE require rule out using __ scan
