Background and Identification
The Nellcor Intouch is a remote oximetry notification system made by Medtronic's Nellcor division. The Nellcor division focuses mainly on producing pulse oximeters and oxygen monitors. The Nellcor Intouch system connects to a compatible pulse oximeter with an appropriate cable. When the pulse oximeter produces an alarm, the Intouch transmitter sends the alarm to a designated pager.
The Intouch system is an alarm notification system designed to work with the Nellcor NPB-290, NPB-295, N-395, and N-300 pulse oximetry models. Pulse oximeters are non-invasive devices used to monitor a patient’s oxygen saturation. The Nellcor Intouch system connects to a compatible pulse oximeter with an appropriate cable. When the pulse oximeter produces an alarm, the Intouch transmitter sends the alarm to a designated pager. The Intouch pager is typically worn by a caregiver. When an alarm is produced, the pager displays the patient’s bed number, alarm type, and the patient’s monitored parameters. The Nellcor Intouch system serves as a redundant mechanism to alert clinical staff of important patient events. This device is suitable for continuously monitoring adult, pediatric, and neonatal patients.
The Nellcor Intouch system includes the name “NELLCOR Intouch” on the top of the device. Other identifying information may be printed on the device’s front face, such as the word “COMPAQ.”
Technical Specifications
Single Alarm Response Time: Patient alarms will be received by the pager within 10 seconds for single patient alarm events.
Multiple Alarm Response Time: In the case of separate, simultaneous alarms at five transmitters, all alarms will be received by the pager within 60 seconds.
Configuration: Within one Intouch system, up to 24 transmitters and 12 pagers may operate on one frequency and be programmable by one programmer.
- Up to 6 sets of 24 transmitters, each set operating on its own channel, may be used in the same hospital or healthcare facility.
