NAR-S Capnograph

The screen is bright enough to read even in direct sunlight, which made a huge difference during our night shift checks. It's compact enough to clip onto a vest without getting in the way, and the response time on the ventilation data feels instant.

Took it on a wilderness rescue rotation and the screen stayed readable even in bright sun, which was my biggest worry. The readings felt solid and consistent every time I checked ventilation status, and it survived a rough bump in the pack without a hiccup. Exactly what I needed for backcountry call

I’ve used it during two field shifts and the respiratory data updates fast enough that I catch changes in ventilation before they become a problem. The build feels rugged, and the layout of the controls is intuitive even when I’m wearing gloves.
