Background and Identification
The Nellcor NPB-190 is a pulse oximeter made by Mallinckrodt’s Nellcor division. Pulse oximeters are non-invasive devices used to monitor a patient’s oxygen saturation. The Nellcor division focuses mainly on producing pulse oximeters and oxygen monitors.
The Nellcor NPB-190 model is a portable pulse oximeter designed for continuous monitoring of pulse rate and functional oxygen saturation of arterial hemoglobin. This device is suitable for continuously monitoring adult, pediatric, and neonatal patients. It can be used in the home or in all hospital-type facilities. During intra-hospital transport, this monitor can also be powered by its internal battery.
Pulse rate and oxygen saturation are shown on digital displays. The pulse amplitude is shown on a 10-segment LED bar. When the oxygen saturation and pulse rate moves outside their set limits, an audible alarm is produced. The user can adjust high and low alarm limits for oxygen saturation and pulse rate.
The Nellcor NPB-190 includes the name “NELLCOR PURITAN BENNETT” printed in capital letters at the top of the monitor’s front face. The model name, “NPB-190” is printed above the pulse rate display on the device’s front face. An array of controls and indicators are placed on the front face of the pulse oximeter.
