Clinical verification of RespiHeart at an Emergency Department
|Funding from Vinnova||SEK 400 000|
|Project duration||November 2016 - May 2017|
Purpose and goal
The purpose of the project has been to verify RespiHeart patient monitoring of respiratory rate, heart rate, oxygen saturation and temperature. The achieved objectives have been to evaluate: (1) functionality, incl. usability, presentation interface and communication, (2) precision in comparison with standard methods at an emergency department, (3) guide forthcoming development of the RespiHeart system, and (4) to describe prerequisites for system optimization in a clinical context and adaptation of the product to situational circumstances at an emergency department.
Expected results and effects
RespiHeart demonstrates high precision for heart rate and oxygen saturation. Respiratory rate needs to be further studied due to differences in signal processing. Temperature measurement reveals delays up to 10 minutes with existing technology. RespiHeart is found to be an effective and time saving system enabling vital signs monitoring for the large number of emergency patients currently not possible to monitor with existing methods. Future development of RespiHeart needs to include EHR connectivity, sensor display, and motion artefacts compensation.
Planned approach and implementation
The project has been conducted at the emergency department at Linköping University Hospital. 50 patients have been monitored during 10 minutes each, using RespiHeart, Philips MP30 and Covidien in parallel. Measurement data has been systematized, analyzed and compared. Functionality, usability, and technical integration opportunities have been studied based on interviews with clinicians participating in the data collection. Technical prerequisites and patient logistics have been studied based on health care process and scenario analysis.
