Patent Images
1. A portable capnography system, comprising:
- a patient interface unit, configured to receive samples of air from an exhaled breath of a subject;
a portable carbon dioxide (CO2) sensor;
a portable pump, configured to deliver breath samples from said patient interface unit to said portable CO2 sensor; and
a portable control circuitry configured to analyze signals obtained from said CO2 sensor,wherein at least one of said portable CO2 sensor, portable pump and portable control circuitry have at least a first and a second operational modes, and said control circuitry is configured to alternate between said at least first and second operational modes of at least one of said portable CO2 sensor, said portable pump and said portable control circuitry.

Abstract
The present disclosure provides portable capnography systems having multiple operational modes, with varying power consumption. Alternation between the operational modes may be conducted to reduce the overall power consumption of capnography systems. The power reduction may be advantageous in enabling capnography systems to be powered by mobile power sources.
