|
Main fxns of IABP
|
increase perfusion to coronary arteries
decrease afterload |
|
|
Secondary fxns of IABP
|
decrease workload of heart
decrease myocardial O2 demand |
|
|
counterpulsation
|
volume displacement created by rapidly shooting helium in and out of balloon
|
|
|
normal adult IABP balloon size (volume)
|
40 ml
|
|
|
Normal IABP placement location
|
tip 1-2 cm below L SC artery and above renal arteries
(CXR-btwn 2nd & 3rd intercostal space) |
|
|
what is the augmented diastolic wave form & what do you compare it to?
|
It is the wave created when balloon inflates and it should be higher than the patient's unassisted systolic
|
|
|
what is the augmented end diastolic wave and what do you compare it to?
|
This is the wave created after the balloon has deflated at end diastole. IT should be lower than the patient's own diastolic pressure d/t sxn created when balloon rapidly deflates
|
|
|
what is assisted systole and what do you compare it with?
|
It is the patient's systolic peak wave after balloon pump has inflated and deflated and afterload has been reduced so it should be lower than the unassisted peak systolic
|
|
|
When should IABP inflate?
|
onset of diastole (diacrotic notch or peak of T wave)
|
|
|
diacrotic notch
|
notch in arterial waveform when semilunar valves shut (aortic and pulmonic valves). Marks start of diastole
|
|
Name the waves
|
A= unassisted end diastolic
B= unassisted peak systolic C= diacrotic notch D= assisted peak systolic E= augmented diastolic |
|
|
What IVF should be pressurizing the central lumen of the IABP?
|
1000 units heparin in 500 ml bag of 1/2 NS
|
|
|
What sign tells you IABP may have been inserted too high? too low?
|
too high= absent left radial pulse
too low = abnormal u/o (bloody, decreased) |
|
|
Balloon inflation pressure should not be more than _____
|
40 ml
|
|
|
hallmark sign of IABP rupture is:
|
blood in the connecting tubing, this requires immediate cessation of IABP and lowering of HOB and call MD,
DO NOT let blood fluid reach IABP console! |
|
|
IABP pressure readings must be recorded every ____ in EPIC
|
hour
|
