Left Ventricular Assist Devices - LVADs
Heart Pump
LVADs: HYPO-PERFUSION
- NORMAL SALINE:
- 1L IV/IO, titrate to desired effect. Assess lung sounds and BP frequently
May repeat 1x, prn
LVADs: UNRESPONSIVE PATIENTS
- ONLY perform chest compressions when the patient’s LVAD is not working and no other options exist to restart the LVAD
- Evaluate unresponsive patients carefully for reversible causes by assessing:
- A.E.I.O.U.-T.I.P.S.
- H’s & T’s
- CHECK BGL
CHEST COMPRESSIONS: - Position hands to the right of the sternum to avoid LVAD dislodgement
Contraindication: - DO NOT use the AutoPulse
Precaution - Performing chest compressions risks rupturing of the ventricular wall leading, to fatal hemorrhage
LVADs: TRANSPORT
- Non-LVAD chief complaints should be transported according to the “Transport Destinations” protocol
- If there are any questions regarding this, contact the EMS Captain and LVAD Coordinator
- JFK MEDICAL CENTER LVAD COORDINATOR:
- (561) 548-5823. Any LVAD issue should be transported to JFK Medical Center
