Advances in main-stream sensor technology

New developments in main stream sensor technology has overcome many disadvantages associated with earlier models such as heavy weight, bulky size, facial burns as result heated sensors, and increased drag on the endotracheal tubes. In addition, an aspiration sampling pump has been incorporated into the system so that main stream sensors can function as side stream sensors in non intubated patients.

Plug & Play CO2 modules

Respironics has recently released several new versions of technology. The CAPNOSTAT® 5 is a new solid state mainstream CO2 sensor which is small and lightweight. It provides a variety of airway adapters to monitor adult, pediatric and neonatal patients.

In addition they have released LoFlo®, a new Sidestream sensor. The LoFlo technology has a 50cc sampling rate and has a new external sample cell which is attached to the patient interface rather than housed inside the monitor. This design eliminates the need for the respiratory gas sample to be pulled inside the internal infrared measurement bench and eliminates the associated contamination complications as experienced in traditional sidestream systems. A wide selection of nasal cannulas, traditional, oral and dual O2/CO2, are available which allow easy monitoring of non-intubated patients.

The Capnostat 5 and LoFlo sensors utilize the same electronics which makes them easily interchangeable depending on the type of patient, intubated or non-intubated, you are monitoring.
