Spacelabs Medical, Inc. (Nasdaq: SLMD SLMD Subscriber Line Module Digital ) announces systems to help hospitals respond to a move by the FCC (1) (Federal Communications Commission, Washington, DC, www.fcc.gov) The U.S. government agency that regulates interstate and international communications including wire, cable, radio, TV and satellite. The FCC was created under the U.S. designed to end the threat of high-definition television high-definition television (HDTV)
Any system producing significantly greater picture resolution than that of the ordinary 525-line (625-line in Europe) television screen. Conventional television transmits signals in analog form. and new business radio wireless transmissions potentially interfering with and disabling medical telemetry telemetry
Highly automated communications process by which data are collected from instruments located at remote or inaccessible points and transmitted to receiving equipment for measurement, monitoring, display, and recording. systems.
The FCC created the Wireless Medical Telemetry Service (WMTS WMTS Wireless Medical Telemetry Service
WMTS Wireless Modem Termination System
WMTS Wireless Message Transfer System (Vyyo) ) on June 8, 2000. The WMTS designates specific radio frequency (RF) bands for medical telemetry operation -- 608-614 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. , 1395-1400 MHz and 1429-1432 MHz. Spacelabs was the first manufacturer with telemetry products operating in the newly protected range. Spacelabs introduced a new digital telemetry system in October 1999, which operates in the 608-614 MHz band.
"Our experience since October has shown that the 608-614 MHz range is a good path out of the frequency bands that are prone to RF interference," said Stan Wiley, director of product development for telemetry products at Spacelabs.
Historically, hospital telemetry systems have operated in the Private Land Mobile Radio band (450-470 MHz) or on unused television channels. In recent years an increase in the use of mobile radios and implementation of digital television have increased the incidents of RF interference, disrupting vital signs monitoring provided by medical telemetry systems.
Neither mobile radios nor television broadcasts are allowed to operate in the newly designated WMTS frequencies. Hospitals may elect to continue to operate their installed telemetry systems on the old bands as secondary users, but will do so at their own risk.
"This ruling constitutes a clear message to hospitals that they should migrate to the less susceptible bands," commented Wiley. "As mobile radio and digital television applications continue to grow, hospitals risk interference to medical telemetry systems not operating in the new WMTS frequency ranges."
Spacelabs was instrumental in the creation of the Critical Care Spectrum Act of 1999, which was introduced to Congress by US Congressman Jay Inslee Jay Robert Inslee (born February 9, 1951) is an American politician, currently serving as U.S. Representative from Washington's 1st congressional district (north of Seattle, including parts of King, Snohomish, and Kitsap counties). He is a Democrat. He lives on Bainbridge Island. . The Company also served as a Charter Member of the Task Force on Medical Telemetry established by the American Hospital Association American Hospital Association (AHA),
n.pr a nonprofit national organization of individuals, institutions, and organizations engaged in direct patient care. The association works to promote the improvement of health care services. .
