What does an HME do?
Heat and Moisture Exchangers (HMEs) help to reduce mucus production and coughing by humidifying and filtering the air you breathe through your stoma.
What is an HME for a trach?
An HME is a humidifying filter that fits onto the end of the trach tube and comes in several shapes and sizes (all styles fit over the standard trach tube opening). There are also HME's available for portable ventilators. Bedside ventilators have built-in humidifiers.
What is the life expectancy of someone with a trach?
The median survival after tracheostomy was 21 months (range, 0-155 months). The survival rate was 65% by 1 year and 45% by 2 years after tracheostomy. Survival was significantly shorter in patients older than 60 years at tracheostomy, with a hazard ratio of dying of 2.1 (95% confidence interval, 1.1-3.9).
Can you talk with a trach in place?
It's usually difficult to speak if you have a tracheostomy. Speech is generated when air passes over the vocal cords at the back of the throat. But after a tracheostomy most of the air you breathe out will pass through your tracheostomy tube rather than over your vocal cords.
How long can you use an HME?
Use of HMEs for >24 hrs, up to 72 hrs, is safe and cost effective.
When should you not use an HME?
Do not use a heat moisture exchanger (HME) for a patient who has thick, copious, or bloody secretions, expired tidal volumes of less than 70% of the delivered tidal volume, a body temperature less than 32°C (89.6°F), or high spontaneous minute volumes greater than 10 L/min.
How often should HME be changed?
Change the HME at least every 24 hours and more frequently, as needed. Change the HME when patient complains about increased breathing resistance, which may occur if the HME becomes saturated with mucus.

How Does Condensation Appear?
Many properties, especially tenanted flats can suffer from condensation, resulting in black or green mould growth developing on furnishings, clothing and the walls, ceilings and surfaces within the property. This can be a result of poor ventilation and heating control. Cooking, cleaning , drying clothes etc and simply breathing will all generate moisture that needs to be vented to avoid cold surfaces become damp and mouldy.
How Does Condensation Control Work?
We have a wide range of solutions from humidity controlled extractors, single room heat recovery and whole house ventilation systems. Our engineers will supply and install the systems which are completely automated and require no control from the occupants of the property, ensuring correct ventilation as required.
What is Kenwood ventilation?
Kenwood Plc has a range of systems for condensation control London, from simple extractor ventilators, single room solutions, incorporating heat recovery ventilator s, to full positive pressure ventilation systems, which displace and dilute moisture-laden air and ensure air circulation within the property.
What is the principle of introducing a supply of fresh, filtered air, whilst removing damp,?
The principle of introducing a supply of fresh, filtered air, whilst removing damp, moist air via the passive ventilators elsewhere in the property provides an excellent solution for overcoming condensation problems in residential flats ensuring a healthy living space.
What is a Kenwood positive pressure ventilation system?
Where condensation is more widespread, the Kenwood Positive Pressure Ventilation system© is an effective solution. A Kenwood condensation control unit is fitted to an external wall and operates by introducing fresh, filtered air into the property. In cooler weather, the automated temperature sensor activates, and the unit will gently temper the incoming air to reduce heat loss.
Is Kenwood Heat Recovery Ventilator good for single rooms?
The Kenwood Heat Recovery System is most suitable for single rooms such as bedrooms. Where condensation is present within a bedroom or lounge environment, boost extract is undesirable and therefore the preferred solution is a Kenwood Heat Recovery ventilator©.
Can condensation control be used in a house?
Condensation control can help common household or domestic damp issues. These concerns can occur in blocks of flats , single households and commercial buildings alike, but is most common in residential buildings. Failing to use effective condensation control methods could cause wider issues for the whole building, but there are simple solutions.
What Is Humidity?
Ever heard the phrase 'It's not the heat, it's the humidity'? People say this because humidity, which is the amount of water vapor in the air, can make hot temperatures even more unbearable than they already are. Humidity is actually a broad term, and we can describe different types of humidity in different ways.
What is relative humidity?
Relative Humidity. You've probably heard about relative humidity in weather reports. This is the amount of water vapor in the air relative to what the air can hold. Think about it this way: if you have a cup that is half-full of water, the cup contains 50% of what it can hold. Air works the same way.
How much water vapor does air hold?
Let's say that a certain parcel of air, or a clump of air that shares similar properties, can hold 30 grams of water vapor per cubic meter of air, but it only has 15 grams of water vapor per cubic meter of air.
What is the relative humidity of a 12 oz cup?
If the 12-ounce cup represents cold air and the 24-ounce cup represents warm air, the relative humidity for the cold air is 50%, but for the same amount of water in warm air, the relative humidity is only 25%. How full the cup is relates to how much the cup can hold overall. When we apply this to air, we can see that for the same amount ...
Why do we see dew in the morning?
Therefore, the temperature at which saturation occurs is called the dew point. You most commonly see dew in the morning because air temperature goes down overnight. And remember, cold air can't hold as much water, so it's like you're taking the larger cup (warm air) and pouring it into a smaller one (cold air).
Why is humidity higher in cold air than warm air?
When we apply this to air, we can see that for the same amount of water vapor, the relative humidity will be higher for cold air than for warm air because the cold air is 'fuller' from the same amount of water.
Why is humidity important?
Humidity is an important thing to understand because it affects both weather and climate as well as global climate change. Humidity also affects indoor environments, so understanding it can help you determine the best place to store your books, clothing and other important items in your house. {"error":true,"iframe":true}.
What is HME in medical terms?
Heat and Moisture Exchanger’s (HME) are used in mechanically ventilated and laryngectomy patients to heat and moisturize the air and help prevent complications that arise when patients lose the ability to breathe through their nose and upper airway.
What is thermomovent T?
The Thermovent® T is a Heat & Moisture Exchanger (HME) captures heat and moisture on expiration and returns it to the patient in inspiration. It is suitable for spontaneously breathing patients with a tracheostomy tube.
