Metered dose inhalers, which are also commonly called “puffers or inhalers”, spray the medicine out so that you can breathe it deep into the lungs. Show Inhalers deliver medicine very quickly. Inhalers are compact and light– so they can be easily taken with you wherever you go. It’s very important to use your inhaler the correct way to make sure the medicine gets deposited in the lungs, where it works the best. Incorrect technique can leave some of the particles from the medicine on your tongue or throat, where it won’t help at all. A spacer, or holding chamber, is an attachment that should always be used with your inhaler. The spacer holds the medicine in place so you can breathe it in easier. Now let’s demonstrate how to correctly use a spacer and mouthpiece. First, remove the cap from the bottom of your inhaler. When you get your new inhaler from the pharmacy, you need to “prime” or “waste” it by spraying the medicine into the air 4 times. Now, fit your inhaler into the opening at the end of the spacer. Shake the inhaler well for 10 seconds. Turn your head to the side and breathe out. Close mouth around mouthpiece of spacer. Push down on the inhaler once. Now the medicine is inside the spacer. Right away, take a slow, deep breath. The goal is to not hear a whistling sound. If you do, this means that you’re breathing in too fast. Hold your breath for a count of 10. Now, slowly breathe out. Rinse your mouth out with water, or brush teeth, or get a drink after using controller medicines, such as inhaled steroids. Many times, the correct dose of your medicine will be to inhale 2 puffs. If this is what is prescribed for you, then wait one minute after the first puff, and then follow all of the steps again. Clean the plastic holder of the inhaler each week. For inhalers with a built-in counter do not remove the metal canister. Use a cotton swab to clean the opening where the medicine sprays out of the canister. For inhalers without a built-in counter, run warm water through it, shake off water and set overnight to dry. Clean the spacer each week by soaking in warm soapy water for 15 minutes and run water through it, shake off water and set overnight to dry. Remember if you have questions, call your doctor’s office, asthma care team or pharmacy. Easy-to-read medicine information about spacers – what they are and how to use them. Spacers are clear plastic tubes with a mouthpiece or mask on one end and a hole for your inhaler at the other. A valve in the spacer mouthpiece opens as you breathe in and closes as you breathe out. A spacer makes your MDI (metered dose inhaler) easy to use and more effective for people of all ages. Use your spacer with preventer, reliever, symptom controller and combination medicines. Spacers are available free of charge from your doctor or respiratory educator. How does a spacer help?

How to use a spacer AND maskIf you are using a mask together with a spacer for your child place the mask on your child’s face, covering the mouth and nose ensuring there are no gaps. A mask is used for babies and infants that cannot seal their lips around the mouthpiece. Most children should be able to use the spacer without a mask by the age of 3 years. If you are using a mask with preventer medication wash the child’s face after use. Regular cleaningWash your spacer once a week with warm water and dishwashing liquid. Check your spacer for cracks. If used regularly your spacer may need to replaced every 12-24 months. Source: eChamber spacer information Learn moreeChamber spacer information Apex Medical
Many people have a hard time learning how to use metered dose inhalers correctly. Quite often, too much of asthma medicine ends up in the mouth and throat instead of passing into the lung's small airways where it is most needed to control the asthma symptoms. The result can be poor control of asthma, as well as side effects from getting the wrong dose of medicine, like sore throat, dry mouth, bad taste etc. A spacer device is a large plastic container, usually in two halves that click together. At one end is a mouthpiece and at the other end is a hole for inserting the mouthpiece of an MDI. The dose from your inhaler is sprayed into the spacer, from where it can be inhaled without needing to coordinate breathing and pushing down the inhaler canister. There are several brands of spacer device available and they are all different (including Volumatic, Optichamber and Aerochamber). Each spacer device fits different inhalers and so it is important to get the right spacer device that fits your inhaler. The inhaler mouthpiece must fit properly into the spacer hole. Spacers are available on prescription. In order to properly use an inhaler without a spacer, one has to coordinate a certain number of actions in a set order (pressing down on the inhaler, breathing in deeply as soon as the medication is released, holding your breath, exhaling), and not all patients are able to master this sequence. Use of a spacer avoids such timing issues. Spacers slow down the speed of the aerosol coming from the inhaler, meaning that less of the asthma drug impacts on the back of the mouth and somewhat more may get into the lungs. Because of this, less medication is needed for an effective dose to reach the lungs, and there are fewer side effects from corticosteroid residue in the mouth. Valves on a spacer (which technically makes it a holding chamber) cause the patient to inhale the contents of the spacer, but exhalation goes out into the air. The problem of coordinating an inspiration with a press of an inhaler is avoided, making use easier for children under 5 and the elderly. It also makes asthma medication easier to deliver during an attack. So use of spacer is advised by many.

On this page: What is a spacer?Spacers are empty tubes that are usually made from plastic. They slot onto the mouthpiece of your inhaler on one end, and you use a mouthpiece or mask on the spacer at the other end. They help you get the best from your asthma medicine if you use a metered dose inhaler (MDI). If you’re using a dry powder inhaler (DPI) or a breath-actuated inhaler (BAI), you won’t need to use a spacer. Speak to your GP or asthma nurse if you’re not sure which type of inhaler you’re using. Types of spacerThere are several different brands of spacer that fit different inhalers and are available on prescription (including Volumatic, AeroChamber, Able Spacer, Space Chamber Plus, and A2A spacer). Speak to your GP, asthma nurse or pharmacist about finding the right spacer for you. You can also buy a spacer from your pharmacy without a prescription. What are the benefits of using a spacer?Using a spacer with your metered dose inhaler (MDI) helps the right amount of medicine get to your lungs. Using a spacer will mean:
How to use a spacerYour GP, asthma nurse or pharmacist should show you how to use your inhaler and spacer properly. You can also check your technique at your annual asthma review. There are two breathing techniques for adults and children to use with a spacer: ‘tidal or multiple breathing’ and ‘single breath and hold’: Both techniques work equally well. Multiple breathing may be prescribed to younger children as it’s easier to teach. Multiple breathing may also be prescribed if you’re having an asthma attack. Top tips for adults using spacers

Looking after your spacerReplacing and disposing of your spacersYou should replace your spacer at least every year, especially if you use it daily, but some may need to be replaced sooner – ask your GP, asthma nurse or pharmacist if you’re unsure. Check the information leaflet that comes with your spacer to find out how to dispose of it. Spacers are not widely recycled so you may need to dispose of it in normal household waste. If you’re using a spacer with rubber valves, replace it if the valves become stiff or brittle. Tips for cleaning your spacerIf it’s a new spacer, clean it before you use it for the first time, then once a month afterwards.
When you’re not using your spacer, storing it properly will keep it in good condition, helping you or your child to get the best from your asthma medicine.
