With the next breath in, the air passes through the HME and becomes warm and moist.</p><p>AN HME is sometimes called an artificial nose because it also acts as a filter and can prevent small particles from entering the trachea.</p> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_venturi_device_01_EN.jpg" alt="A Venturi device showing the oxygen machine, mask and multi-coloured connectors" /> <figcaption class="asset-image-caption">A Venturi device showing the oxygen machine, mask and multi-coloured connectors for different amounts of oxygen</figcaption> </figure> <h3>Points to note about an HME</h3><ul><li>An HME provides less humidification than other devices.</li><li>Children with a lot of secretions are sometimes not able to use an HME because their secretions cannot be properly cleared with the HME in place.</li><li>For some children, an HME makes it harder to breathe.</li></ul><p>Talk to your healthcare team about whether an HME is right for your child.</p><h2>HME types and sizes</h2><p>HMEs come in many different types and sizes. Your healthcare team will tell you which one is right for your child. The following are examples of different HMEs:</p><ul><li>GE HCH/BREATHE EASY HME, for children who weigh less than 5 kilograms (11 lbs)</li><li>Trach-Vent HME, for children who weigh more than 5 kilograms (11 lbs).</li></ul><h2>How often should I change my child's HME?</h2><p>Change the HME:</p><ul><li>every day, if your child is using the HME throughout the day and night</li><li>every second day, if your child is using the HME only during the day</li><li>as soon as possible, if it gets dirty<br></li><li>as soon as possible, if it gets plugged with mucus.</li></ul><div class="caution"><h3>Precaution</h3><p>​Do not let water come in contact with the HME.​​</p></div><p></p><div class="asset-4-up"> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_HMEs_02_EN.jpg" alt="A GE HCH/BREATHE EASY HME" /> <figcaption class="asset-image-caption">A GE HCH/BREATHE EASY HME, for children who weigh less than 5 kilograms (11 lbs)</figcaption> </figure><figure> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_HMEs_03_EN.jpg" alt="A Tracheostomy-Vent HME for children who weigh more than 5 kilograms (11 lbs)" /> <figcaption class="asset-image-caption">A tracheostomy-vent HME for children who weigh more than 5 kilograms (11 lbs)</figcaption></figure><figure><img src="https://assets.aboutkidshealth.ca/akhassets/trach_HMEs_04_EN.jpg" alt="An inline HME for a ventilator" /><figcaption class="asset-image-caption">An inline HME for use with a a ventilator</figcaption> </figure> <figure> <img src="https://assets.aboutkidshealth.ca/akhassets/trach_HMEs_05_EN.jpg" alt="An inline HME on ventilator patient connector" /> <figcaption class="asset-image-caption">Close up of an inline HME with the ventilator circuit</figcaption></figure> </div> <a class="btn btn-primary" href="https://www.aboutkidshealth.ca/trachvent">Return to trach-vent learning hub</a><br>Heat and moisture exchanger (large volume nebulizer)Truehttps://www.aboutkidshealth.ca/Article?contentid=2923&language=Englishhttps://www.aboutkidshealth.ca/Article?contentid=2921&language=English
