XtraFlow HME

Atos Medical Provox XtraFlow HME is a heat and moisture exchanger (HME) that heats and humidifies inhaled air by retaining heat and moisture from exhaled air in the device. It is a single-use, specialized device intended for breathing through a tracheostomy. The Provox XtraHME Cassette partially restores lost breathing resistance. Patients with a voice prosthesis or surgical speech fistula may also facilitate voicing.

Why choose Provox HME System?

  • Low breathing resistance
  • Reduces coughing and mucus production
  • Easy occlusion of the stoma for voicing
  • Low-profile design

Atos Medical Provox Xtraflow HME Features

  • Helps make it easier to breathe
  • Use it during the day when you are physically active
  • If you have a voice prosthesis, simply press the HME to speak
  • The top lid can be pushed down with a finger to close the cassette and redirect air through the voice prosthesis to enable speech

Provox Xtra HME Lifetime and Disposal

  • The HME is for single use and must be replaced at least every 24 hours, or more often if needed.
  • Always follow medical practice and national requirements regarding biohazard when disposing of a used medical device.

Precautions to take while using Provox HME System

  • Always test the function of the Provox XtraHME Cassette prior to use. The top lid should immediately return to its open position after releasing the finger.
  • Do not disassemble the Provox XtraHME Cassette since this will interfere with its proper function.
  • Do not reuse the Provox XtraHME Cassette or attempt to rinse it with water or any other substance. This will substantially reduce the function of the HME. Additionally the risk of potential infections may increase due to bacterial colonization of the foam.
  • Do not use the Provox XtraHME Cassette longer than 24 hours. The risk of potential infections may increase with the time of use due to bacterial colonization of the foam.
  • Do not administer medicated nebulizer treatment over the device since the medication can become deposited in the device.
  • Do not use humidifiers or heated humidified oxygen via a mask over the tracheostoma while using the device. The HME will become too wet. If oxygen therapy is required, use only non-heated humidified oxygen.
