Health Canada Reminds Canadians to Check Medical Device Clocks After Switch to Standard Time

OTTAWA, ONTARIO--(Marketwire - Oct. 30, 2009) - Health Canada would like to remind the thousands of Canadians who rely on medical devices or systems with internal clocks to check these devices to ensure they continue to work properly during the switch from Daylight Saving Time to Standard Time this weekend.

The start and end dates of Daylight Saving Time were permanently changed in 2007. Medical equipment manufactured prior to 2007 may not function properly if the equipment has not been updated by manufacturers to compensate for the new dates. Canadians revert to Standard Time this year at 2 a.m. on Sunday, November 1.

Health Canada received no reports of device malfunctions because of the time change in 2007, 2008 and the spring of 2009. However, examples of medical devices that could be affected by the change include (but are not limited to): implanted pacemakers/defibrillators with sleep modes that can only be adjusted by physicians; Holter monitors, used to continuously record heartbeat; and glucose monitors that store data on glucose levels.

If a medical device displays the incorrect time after 2:00 a.m. on Sunday, November 1, 2009, users should tell the manufacturer about the problem and talk to their doctor.
