We want to share with you some information about a new device that is being implanted into cardiac patients in specialty hospitals, and these patients are eventually sent home. The device, called the HeartMate II, is currently being used by at least a half dozen patients in Genesee County. This is a Left Ventricular Assist Device (LVAD), which is an implantable blood pump that takes over the pumping function of the heart's left ventricle. This device contains an electric motor and a driveline that exits the abdomen. The driveline connects to a small controller, which is a mini-computer that controls pump operation. Because these patients are living in Genesee County, you may encounter them, so we wanted to share some information about their condition and this device.
· Because of the way the pump functions, a pulsation is not produced making it difficult to palpate a pulse or obtain a blood pressure without a Doppler.
· When the device is functioning properly the patient will have a normal EKG on the screen.
· It is not recommended that CPR be performed on these patients as this may dislodge the pump. However, if all other efforts have been made to ensure that the pump is functioning or to return it to proper operation, obviously CPR can be performed.
· The patients and their families have been instructed on the proper use and maintenance of the pump and will be able to replace batteries and controllers. They will also be a good source of information should you arrive on scene to treat these patients.
· The patient’s family should be allowed to travel in the ambulance as they are familiar with the device and can adjust it.
· You may respond to a patient complaint that is not directly connected to a cardiac issue. In those cases you should treat the patient according to GCMCA protocols and leave the device alone.
· If the patient’s chief complaint is cardiac in nature you should follow ACLS protocols with the exception of conducting CPR until efforts to ensure proper pump function have been addressed as outlined above.
While it is unlikely that you will respond to one of these patients, we felt that it was important for you to be aware of the possibility. If you or others in your agency are interested in learning more about this device, we have a DVD and other printed materials that you are welcome to review.
Thank you for your attention to this matter and please feel free to contact me should you have any questions or concerns about this issue.
