Clinical evidence supporting Provox Life – Ward study
New clinical study shows changes in pulmonary outcomes as a result of implementing a Day and Night regimen with Heat and Moisture Exchangers (HMEs).
Study objectives
The objective of the study was to evaluate the effect of the use of next generation devices (Provox Life) and the establishment of an optimal day and night regimen on pulmonary health, HME adherence and use, sleep, skin irritation, quality of life and participants’ overall satisfaction.
Study outcomes
The objectives of the new clinical study were to examine changes in pulmonary and related symptoms using a new generation of Provox Life HMEs. The study was a two-phase clinical trial wherein participants transitioned from Provox HMEs to comparable Provox Life HMEs while maintaining their current usage patterns. In the second stage, patients used different types of Provox Life HMEs based on the activity, aiming for the highest possible humification for day and night. The following results were reported:
- During stage one, transitioning from Provox HMEs to the higher performing Provox Life HMEs significantly improved overall pulmonary health
- During stage two, using the highest humidification Provox Life HMEs optimally during the day and night further improved pulmonary health
- Quality of sleep improved significantly when Provox Life HMEs were used throughout the day and night
- Using the new generation of Provox Life HMEs enhanced HME adherence and facilitated the use of an optimal day and night regimen
Conclusions
- The transition from using Provox HMEs to Provox Life HMEs improves pulmonary health, due to the enhanced humidification properties of the new generation devices.
- Better breathability of the new generation Provox Life HMEs and ability to change devices to suit the activity level, improves HME adherence in established HME users.
- Implementing an optimal Day a Night regimen (using the highest humidification HME for the situation) further improves pulmonary health and sleep quality.
“We’re thrilled to see the benefit that this data will bring to the laryngectomy patient community. The study confirms previous research where we saw significant improvements in pulmonary symptoms when transitioning to a new generation of HMEs, Provox Life. This study underlines the importance of optimizing humidification and breathability during the day and night by using a range of HMEs depending on your activity level to attain longer device adherence,” said Allana Kelley, Vice President, Medical and Scientific Affairs, Atos Medical.
