QUESTION 1/5 - LVAD

Question 1/5 - LVAD

Explanation

A MAP of 95–100 mmHg is too high for a patient with a LVAD. When blood pressure is elevated, afterload increases, meaning the LVAD has to pump against more resistance. As aferload inceases:

• Forward flow through the LVAD decreases
• Blood moves more slowly through the pump
• Blood stasis occurs, which increases the risk for clot (thrombus) formation inside the pump

QUESTION 2/5 - LVAD

QUESTION 2/5 - LVAD

Explanation

Low‑flow alarms occur when LVAD flow is reduced due to low preload or high afterload. This patient shows signs of hypovolemia, leading to decreased preload and less blood entering the pump. Elevated MAPs can also cause low flow by increasing afterload and limiting forward flow.

QUESTION 3/5 - LVAD

QUESTION 3/5 - LVAD

Explanation

You do not have to check the settings on the HM3 backup controller because the settings are stored in the pump (You must still ensure it is charged). You have to check the backup controller settings for the HW, HM2, and BrioVad qShift because their settings are stored in the controller.

QUESTION 4/5 - LVAD

QUESTION 4/5- LVAD

Explanation

In LVAD patients, absence of a pulse alone does not indicate cardiac arrest. However, a MAP <50 mmHg with unresponsiveness and apnea indicates inadequate perfusion. According to AHA guidelines, chest compressions should be initiated when there are signs of circulatory collapse or MAP <50 mmHg, despite the presence of an LVAD.

QUESTION 5/5 - LVAD

QUESTION 5/5 - LVAD

Explanation

Dark, tea‑colored urine in an LVAD patient suggests hemolysis, caused by red blood cell damage within the pump. Rising LDH confirms hemolysis and is concerning for possible pump thrombosis, even when alarms are absent. This is a serious LVAD complication that requires immediate evaluation.
