A breathing rate reading is only as useful as the method behind it.
CTA's standard, CTA-2102.1, Performance Criteria and Testing Protocols for Breathing Rate – Real-World Analysis, gives the consumer health technology industry a shared way to measure and validate breathing rate — across devices, across conditions, in the lab and in everyday life.
The result: more reliable data, stronger validation and greater confidence in the digital health devices people use for wellness and clinical insight.
