Portable and Accurate Measurement Technology

The Nellcor™ N-85 portable pulse oximetry monitor with Microstream™ technology provides both accurate SpO2 and etCO2 values in a single, easy-to-use, handheld device.

Microcap™ handheld capnographs deliver an easy-to-use assessment of respiratory status, whether intubated or non-intubated, in any clinical setting.

Please note that the NellcorTM N-85 portable pulse oximetry monitor is now at End of Life and no longer available for purchase and supply. 


Versatile Design for Fast, Simple Set Up and Use

Handheld monitors that are convenient for spot checks and continuous monitoring in a variety of settings, including EMS and ED transport.
