Respiratory failure & ventilation
Clinical validation of a novel accelerometer-based respiratory rate monitor
Authors' conclusion
The wireless RespX accelerometer-based sensor provides a novel and accurate method for assessing the respiratory rate in awake hospitalised patients compared with capnography.
Study context
- Population
- Hospitalised adults (> 18 years) expected to remain undisturbed for one hourcompleted the study
- Participants
- 29 adults
- Exposure
- RespX accelerometer-based sensor vs capnography
- Outcome
- RR measured by RespX within ± 3 breaths per minute of capnography
