timing
This error causes premature closure of the aortic valve and reduces stroke volume.
What is early inflation
The primary physiologic benefit of IABP inflation during diastole
What is coronary artery perfusion (or diastolic augmentation)
The standard anatomical landmark where the tip of the IABP balloon should rest on a chest X-ray.
What is 1 to 2 cm below the top of the aortic arch (or just distal to the left subclavian artery)?
he most common vascular complication of an IABP insertion, requiring frequent checks of pedal pulses.
What is limb ischemia
This error appears as a sharp drop after the dicrotic notch, resulting in a suboptimal diastolic augment
What is late inflation
The primary benefit of IABP deflation during systole
What is afterload reduction (or decreased myocardial oxygen demand)
The maximum degree of head-of-bed elevation permitted for a patient with a femoral IABP to prevent catheter kinking.
What is 30 degrees
This visual indicator in the IABP tubing suggests a balloon leak or rupture
What is blood in the tubing (or condensation/flecking of blood)
This timing issue fails to provide adequate afterload reduction and can lead to retrograde coronary blood flow.
What is early deflation
This specific pressure should ideally be higher than the patient's native systolic pressure during 1:1 assist mode.
What is diastolic augmentation pressure?
This pump trigger mode uses the R-wave of the ECG to signal inflation and deflation.
What is ECG (or Pattern) trigger
his specific organ is at risk for ischemia if the IABP catheter migrates too far downward (distally) from its optimal position.
What is the kidney (renal artery occlusion)
This error increases myocardial workload and oxygen demand because the balloon remains inflated during early systole
What is late deflation
This specific waveform measurement should be lower than the patient's native end-diastolic pressure if the balloon is deflating correctly.
What is assisted end-diastolic pressure
This emergency action must be taken immediately if the IABP pump stops completely for more than 15–30 minutes, to prevent thrombus formation on the balloon.
What is manually inflating and deflating the balloon
This devastating aortic injury can occur during the blind advancement or improper placement of the catheter.
What is aortic dissection
The precise point on the arterial pressure waveform that signifies the end of systole and marks the target for balloon inflation
What is the dicrotic notch
The mathematical calculation used to verify that the balloon is effectively reducing work for the left ventricle on a waveform.
What is comparing the assisted systolic pressure to the unassisted systolic pressure (assisted should be lower)
This pump trigger mode is the necessary choice when a patient goes into cardiac arrest and requires chest compressions
What is Pressure (or AP) trigger
A hematologic complication caused by the mechanical destruction of platelets as they collide with the inflating balloon
What is thrombocytopenia
