WARNING
Preventricular contractions can be caused by the oscillations of microbubbles when a high-MI
acoustic field is triggered in the heart at the end of systole. In a very sick patient with certain
risk factors, theoretically, this could lead to ventricular fibrillation. Reference: van Der Wouw,
P.A., Brauns, A.C., Bailey, S.E., Powers, J.E., Wilde, A.A. "Premature ventricular contractions
during triggered imaging with ultrasound contrast." Journal of the American Society of
Echocardiography, 2000;13(4):288-94.
WARNING
If a sterile transducer cover becomes compromised during an intraoperative application
involving a patient with transmissible spongiform encephalopathy, such as Creutzfeldt-Jakob
disease, follow the guidelines of the U.S. Centers for Disease Control and this document from
the World Health Organization: WHO/CDS/ APH/2000/3, WHO Infection Control Guidelines
for Transmissible Spongiform Encephalopathies. The transducers for your system cannot be
decontaminated using a heat process.
WARNING
If the system becomes contaminated internally with bodily fluids carrying pathogens, you
must immediately notify your Philips service representative. Components inside the system
cannot be disinfected. In that case, the system must be disposed of as biohazardous material
in accordance with local or federal laws.
WARNING
The backlight lamps in the system displays may contain mercury and must be recycled or
disposed of according to local, state, or federal laws.
WARNING
Select the correct application when starting an exam, and remain in that application
throughout the exam. Some applications are for parts of the body that require lower limits
for acoustic output.
