What would increase RA Pressure?
If the pressure would rise, where would this be visible on a patient?
Tricuspid stenosis
Jugular Enlargement
In an RV MI :
What is the RV pressure?
What is the PA pressure?
25/5 normal
PA would not change
What would cause LV systolic pressure to rise?
Aortic Stenosis
***What would increase LVEDP and not LV systolic pressure?
LV MI
What is the RV systolic pressure of PS?
^ 25 in pressure.
What is the RA pressure of TR (tricuspid regurg)?
Right sided
Pressure will rise^
JVD = true.
What is the PA pressure of COPD?
Pressure is 30
Expansion of Aviolar curus blood vessels
CO = \/
What is the PA pressure of MS?
LA Enlargement Chronic = rise
Acute = same
What is the PA pressure of MR?
La enlargement chronic = rise
acute = same
Could the PA systolic pressure ever be greater than RV systolic pressure?
NEVER
It would back up into the RV.
RA – RV
Ra will always protect the Lungs from the rise of pressure.
