First research study co-sponsored by three companies - Agilent,
Datex-Ohmeda and Mallinckrodt - concludes Nellcor N-395 superior
during challenging conditions
PLEASANTON, Calif., Sept. 14 /PRNewswire/ -- The Nellcor Oximetry business
of Mallinckrodt Inc. (NYSE: MKG) today announced that the Nellcor(R) N-395
with Oxismart(R) XL and Sat Seconds(TM) technology out-performed five other
monitors during motion, according to the results of two separate studies.
Both research projects will be presented at the American Society of
Anesthesiologists conference in San Francisco on October 16.
Separate studies led by Hartmut Gehring, MD, of the Department of
Anesthesiology at Medical University Luebeck, Luebeck, Germany, and Michael W.
Jopling, MD, of the Anesthesiology Department at St. Ann's Hospital Columbus,
Ohio, compared Nellcor N-395 monitors against other brands of pulse oximetry
equipment. In each case, the N-395 oximeters fared best.
Dr. Gehring's study, entitled Artifact Resistance of Newest Generation of
Pulse Oximeters in Volunteers Undergoing Hypoxemia, tested oximetry
performance in healthy adult volunteers during motion combined with simulated
low perfusion, one of the most challenging clinical situations. Five different
pulse oximeters from four manufactures were tested, including Nellcor N-395
and N-3000 monitors, a Datex-Ohmeda 3900, an Agilent CMS Rev. B.0., and a
Schiller OX-1, the European version of the Ivy 2000/Masimo SET(R). The
research was co-sponsored by Agilent, Datex-Ohmeda and Mallinckrodt.
"Combining performance with respect to SpO2 accuracy, pulse rate accuracy
and alarm handling, the Nellcor N-395 demonstrated superior performance in
comparison with other new generation pulse oximeters," concluded Dr. Gehring
and his investigative team.
Dr. Jopling's study investigated the effects of motion artifact on the
alarm performance of the Nellcor N-395/Oxismart(R) XL, Ivy 2000/Masimo SET and
the older technology Nellcor NPB-290/Oxismart. "During severe motion
artifact, the N-395/Oxismart(R) XL exhibited superior performance," concluded
Dr. Jopling and co-investigators in their study, Sensitivity and Specificity
Performance During Motion Artifact in Three Pulse Oximeters Designed for Use
in Motion.
During the more challenging motion conditions, the N-395 detected 30 of 32
hypoxemic events, while the Ivy 2000 and NPB-290 only detected 26 and 19
events, respectively. The N-395 also reported significantly fewer false
alarms, which contributed further to its overall superior sensitivity and
specificity performance compared to the other instruments.
"Unlike other oximetry studies, which use rhythmic motion machines or
pulse-simulating machines, both the Luebeck and Jopling studies test oximetry
performance on human subjects that are simulating real chaotic patient
motion," said Doris Engibous, vice president and general manager, Nellcor
Oximetry Business. "Their research results provide a valuable tool for
clinicians to understand how different oximetry technologies may perform in
challenging clinical situations."
