The N-550 utilizes Nellcor's SatSeconds alarm management technique.
SatSeconds is a function of the software within the N-550. With the
SatSeconds technique, upper and lower alarm limits are set in the same way as
traditional alarm management. The clinician also sets a SatSeconds limit that
allows monitoring of %SpO
of time before an audible alarm sounds. Refer to the N-550 Operator's manual
for managing SatSeconds.
The N-550 takes advantage of increased microprocessing power with
advanced mathematical algorithms. O
allows the N-550 to read through challenging motion conditions to deliver
accurate saturation and pulse rate values. For a definition of motion, as
applicable to the N-550, contact Nellcor's Technical Services Department.
