Heat Moisture Exchanger (HME)

Users of HME's experience fewer problems with coughing and mucous production.  This improves sleep and quality of life.

Provox HME is based on a simple mechanism that is documented as safe and hygienic.  The cassette heats and moisturizes inhaled air and restores breathing resistance to a great extent.
 

A.  Provox HME Cassette:

   Has multiple functions:

• as a heat and moisture exchanger

• facilitates manual stoma occlusion with the help of a simple lid/spring-valve mechanism, thereby improving speech as well as hygiene

• unique side openings that enable airtight closure of the stoma even when HME is covered, which means:

  • HME can be hidden

  • no wet stains on clothing

  • inhaled air can be drawn from the warming body rather directly from the surrounding air.

   Available in two versions:

• Normal, intended for all day use

• HiFlow, for lower airflow resistance, e.g. for physical activity, or when adapting to ones first HME

An HME is most effective when worn day and night.  Usually takes some weeks until the pulmanory symptoms improve.  May be increased mucus production in first days of use.
