Description Of N-550 Pulse Oximeter
The N-550 Pulse Oximeter is indicated for the continuous noninvasive
monitoring of functional oxygen saturation of arterial hemoglobin (SpO
2
) and
pulse rate. The N-550 is intended for use with neonatal, pediatric, and adult
patients during both no-motion and motion conditions and for patients who
are well or poorly perfused in hospitals, hospital-type facilities, intra-hospital
transport, and home environments. For prescription use only.
Note : Hospital use typically covers such areas as general care floors,
operating rooms, special procedure areas, intensive and critical care
areas, within the hospital plus hospital-type facilities. Hospital-type
facilities include physician office based facilities, sleep labs, skilled
nursing facilities, surgicenters, and subacute centers.
Intra-hospital transport includes transport of a patient within the
hospital or hospital-type facility.
Use with any particular patient requires the selection of an appropriate oxygen
transducer as described in the N-550 Operator's Manual.
Motion performance claims are applicable to models MAX-A, MAX-AL,
MAX-P, MAX-N, and MAX-I Nellcor
