From the product intro page:

This pocket-sized, fully quantitative capnometer monitors carbon
dioxide concentrations and respiratory rate in one easy-to-use device.
The Capnocheck® capnometer uses miniaturized mainstream ETCO2
technology, providing unmatched accuracy in a lightweight, cost
effective capnometer.

Unlike other capnometers, the
Capnocheck® capnometer does not need routine calibration. Powered by
two AAA batteries, the device has multiple applications including
intubation verification, an indicator for return of spontaneous
circulation, routine airway management, ventilator transport and
weaning. Unlike colorimetric and other qualitative mechanical devices,
the Capnocheck® capnometer provides a fully quantitative numeric value
that is now recommended in the American Heart Association (AHA) 2005
guidelines. During resuscitation the Capnocheck® capnometer can be an
effective noninvasive indicator of cardiac output, CPR effectiveness,
and indicator for return of spontaneous circulation. The device’s
simple operation and accuracy make it an invaluable tool in all areas
of clinical practice.

Unlike some other product introductions lately, Smiths had their product page already up, and (extra points here) as snazzy photo of the product - pictured right.

Sadly, there's no apparent connectivity. Ironically, the high utilization resulting from a smaller and more convenient a product like this, the greater the need for connectivity. Much like point of care diagnostics, I would imagine that a large majority of the readings taken with a device like this never make it into the patient record. Convenient and immediate vital signs data is important, but when data is not captured into the record valuable trend data is lost.

In physician offices this is less of an issue, but in out patient surgery, acute care settings, and military applications (which the Capnocheck seems ideally suited) data must make it into the record. Outside physician offices, caregiver workloads are too great to expect consistent manual documentation of readings.

The small size of a device like this also presents challenges. What connectivity technology do you use? Docking stations are little better than no connectivity at all from a workflow perspective. Wireless connectivity is ideal, but can be power hungry. Also, there's the issue of user interface. The user must be able to establish patient context at the point of care to positively identify the patient and tag the resulting readings with the proper patient ID. An interesting problem.
