NASA Selects LIFEPAK(R) 1000 Defibrillator from Physio-Control as First Automated External Defibrillator in Space

  LIFEPAK 1000 Defibrillator Deployed on International Space Station

REDMOND, Wash.--(Business Wire)--
Physio-Control of Redmond, Wash., today announced the LIFEPAK 1000
defibrillator has been deployed on the International Space Station
(ISS) as the first automated external defibrillator (AED) in space.
AEDs are easy to use devices that automatically interpret a patient's
heart rhythm and, if necessary, deliver a potentially lifesaving
defibrillation shock. They have become common in places such as
airplanes, health clubs, and schools and now the LIFEPAK 1000 AED will
be available for NASA crew members should someone experience sudden
cardiac arrest in space.

   The ISS has utilized manual defibrillators in the past, but NASA
decided to now deploy an AED because it requires less training and
maintenance, better enabling astronauts to respond to a medical
emergency. The small size and light weight of the 1000 also helped
minimize hardware mass and volume onboard the Space Station.

   NASA conducted extensive evaluations of 18 AEDs available
worldwide before selecting the LIFEPAK 1000 defibrillator to protect
the crew members of the ISS. The AED evaluations focused on user
interface, ease of use, durability and detailed technical
specifications related to the unique conditions encountered in space,
including electromagnetic interference, pressure susceptibility,
temperature, vibration, acceleration and other environmental factors.
Additionally, Medical Operations personnel evaluated the use of
LIFEPAK 1000 in zero gravity conditions aboard a NASA DC-9 test
aircraft as part of developing their advanced life support use

   With the exception of a customized battery developed and provided
by Micro Power Electronics, a leading manufacturer of custom batteries
and power systems, and a NASA-created cover for the device that is
specifically designed for space use to help protect it from
electromagnetic interference, the LIFEPAK 1000 was deployed on board
the Space Station in the same device configuration used by
professional emergency responders.

   "We are honored NASA selected the LIFEPAK 1000 defibrillator to
protect the lives of crew members onboard the International Space
Station," said Brian Webster, president of Physio-Control. "The 1000
is used by thousands of emergency responders worldwide and was
designed for use in the harshest environments and situations; it's
proven to be one of the most reliable products Physio-Control has ever
developed. This 'space first' is especially exciting for us, as it
underscores the many reasons customers choose LIFEPAK defibrillators
for emergency medical use."

   About Sudden Cardiac Arrest and the LIFEPAK 1000 Defibrillator

   Sudden cardiac arrest happens suddenly and without warning, and is
commonly caused by an electrical disturbance in the heart that causes
an individual to go into an abnormal heart rhythm known as ventricular
fibrillation, losing a pulse and consciousness. Immediate CPR and
defibrillation are critical to survival, as survival rates drop about
10 percent every minute without defibrillation.

   Available from Physio-Control since 2006, the LIFEPAK 1000
defibrillator is an AED created for use by basic life support
responders to treat cardiac arrest patients. The 1000 can also be
programmed so those with more advanced training can view the
three-lead ECG onscreen to provide continuous cardiac monitoring. The
1000 provides escalating biphasic energy up to 360 joules.

   About the International Space Station

   The International Space Station is a state-of-the-art, orbiting
laboratory complex that travels 240 miles above the Earth. Assembly
began in 1998 and work on the complex continues today. The first
resident crew established the beginning of a continual human presence
in space and arrived in a Russian capsule as part of Expedition 1 in
November 2000. Since then, astronauts from more than 10 countries have
carried out 17 missions. Crew members currently have interior living
and working space for conducting ongoing medical and space research
with the goal of improving the lives of people all over the world.
