1-4 Introduction
Defibrillation/Cardioversion. The Merlin PSA may be damaged by defibrillation shocks when it is
connected to an implanted lead system. Test the Merlin PSA after it has been exposed to such charges
by launching the PSA application and verifying that the Merlin PSA is functional. Whenever possible,
for the safety of the patient, disconnect the Merlin PSA from the lead system before defibrillation or
cardioversion. After a typical defibrillation shock, the Merlin PSA will recover is less than five seconds.
Environmental Precautions. The Merlin PSA has been carefully designed and tested to ensure
reliability during normal use. However, electronic devices are susceptible to many environmental
stresses. Take precautions to avoid damaging the device, including (but not limited to) the following
examples:
• do not expose the Merlin PSA to extreme temperatures and/or humidity as that may result in
inaccurate measurements
• do not expose the Merlin PSA to mechanical shock as it may damage the Merlin PSA and result in
unreliable measurements
• do not store the Merlin PSA near magnets or magnetic-field-inducing coils as it may shorten its
lifetime.
Other environmental factors may affect proper performance of the device in the hospital setting. Use
of appropriate environmental health and safety practices helps prevent environmental damage to the
device.
Heart-Rate Monitoring. Monitor the patient’s heart rate with an ECG monitor while using the Merlin
PSA.
Liquid Immersion. Do not immerse the Merlin PSA in liquid or damage will result.
