Background and Identification
The Nellcor Puritan Bennett NPB-70 is a handheld capnograph made by Mallinckrodt’s Nellcor division. A capnography monitor is used to measure end-tidal carbon dioxide, which is the amount of carbon dioxide a patient exhales with each breath. The Nellcor division focuses mainly on producing pulse oximeters and oxygen monitors.
The NPB-70 capnograph measures end-tidal carbon dioxide and respiratory rate. It can be used in a wide range of situations, including hospitals and transport environments. This monitor is suitable for use with adult, pediatric, and neonatal patients with a sample flow rate of 50 milliliters per minute. It can be used for mechanically ventilated and spontaneously breathing, intubated, and non-intubated patients.
The NPB-70 is operated using a four-key keypad. End-tidal carbon dioxide measurements are displayed on the left-most seven-segment digital display. The patient’s respiration rate is presented on the right-most seven-segment digital display. An LCD (liquid crystal display) also visually shows the end-tidal carbon dioxide. The model name “NPB-70” is printed in the upper left-hand corner of the monitor’s front face.
For troubleshooting, disassembly, and calibration information, see the Nellcor NPB-70 Service Manual. Failures of the monitor’s housing components including the front cover, rear cover, gas outlet, ON/OFF button, and keypads can be determined by visually inspecting them for deformations and cracks.
