how to use your inhaler

demonstration on how to use your metered dose inhaler and spacer

Here are general instructions for using a metered dose inhaler and spacer.

To begin, shake the inhaler five or six times.

Remove the mouthpiece cover and place the spacer over the mouthpiece at the end of the inhaler.

Put your lips and teeth over the spacer and breathe in slowly. As you do so, squeeze the top of the canister once. Keep inhaling even after you finish the squeeze. Continue inhaling slowly and deeply.

After inhaling, remove the spacer from your mouth and hold your breath for up to 10 seconds.

If you need another dose of medication, repeat the previous steps.

Your inhaler may come with slightly different instructions. Ask your doctor for a demonstration.

How to use dry powder tube inhaler

Here are general instructions for using a dry powder tube inhaler.

To begin, twist the cover off and set it down.

Next, load the dose of medication. Twist the base grip to the right as far as it will go. Twist it back to the left. You will hear a click, which means it's ready to go.

You don't need to shake the inhaler.

Bring the inhaler to your lips in a horizontal position. Put your lips over the tube and take a quick, deep breath. Continue inhaling quickly and deeply.

If you need another dose of medication, repeat the previous steps.

If you accidentally blow into your inhaler after loading a dose, start over and load a new dose. The tube inhaler is designed to deliver one dose at a time.

When you are finished, place the cover back on the inhaler and twist shut. Keep your inhaler dry and store it at room temperature.

Your inhaler may come with slightly different instructions. Ask your doctor for a demonstration.

how to use peak flow meter

A peak flow meter helps monitor respiratory conditions such as asthma, by measuring maximum airflow out of your lungs.

Consult with your doctor as to where to set the color-coded indicators. They are what help determine the status of your airflow.

To begin, hold the meter by the handgrip. Slide the red piston to the bottom of the scale, next to the mouthpiece.

Raise the meter horizontally, inhale deeply, then place your mouth over the mouthpiece and blow forcefully. Make sure your lips act as a seal over the mouthpiece so that no air escapes.

The red piston will slide up the scale. The number that it stops on is your peak flow reading.

Repeat the test two more times. Each time, remember to slide the red indicator back to its start position near the mouthpiece.

Record the highest reading, with the date and time. Your doctor will help determine a personalized scale to use with your meter, dependent on your age, height, sex and health.

how to use dry powder disk inhaler

Here are general instructions for using a dry powder disk inhaler.

To begin, hold the disk level in one hand. With the other hand, put your thumb in the appropriate notch and push it away from you as far as it goes. The mouthpiece will appear and snap into place.

Keep the disk horizontal. Again with your thumb, slide the lever away from you until it clicks.

The disk is now ready to deliver medication.

Put your lips around the mouthpiece. Breathe in quickly and deeply through your mouth — not your nose. After inhaling, remove the disk from your mouth and hold your breath for up to 10 seconds.

To close the disk, put your thumb in the notch and slide it back toward you as far as it goes. The disk will click shut, and the lever will automatically return to its original position. The disk is now ready for your next dose.

Your inhaler may come with slightly different instructions. Ask your doctor for a demonstration.

how to use single dose dry powder inhaler

To begin, remove the inhaler cover. Then hold the base of the inhaler firmly and twist the mouthpiece to open. Push the buttons on each side of the base to test the small spikes within the capsule chamber. These spikes puncture the capsule of medication.

Remove the capsule from its foil container and place it in the capsule chamber at the base of the inhaler. Do not put the capsule in the mouthpiece. Twist the mouthpiece back to a closed position.

With the inhaler upright and vertical, press the spike buttons once. You should hear a click; that's the capsule being pierced.

Release the buttons and prepare to inhale. Do not shake the inhaler.

Bring the inhaler to your lips in a horizontal position. The blue spike buttons should be on the left and right of the inhaler, not top and bottom.

Put your lips over the mouthpiece and breathe in deeply and quickly.

As you inhale, you will experience a sweet taste and hear the capsule spinning in the chamber.

After inhaling, hold your breath for up to 10 seconds.

Open the inhaler to check for leftover powder. If some remains, close the chamber and inhale again.

After use, remove the empty capsule and throw it away. Then close the inhaler and replace the mouthpiece cover.

Your inhaler may come with slightly different instructions. Ask your doctor for a demonstration.

Asthma inhalers: Which one's right for you?

Inhalers allow people with asthma to lead active lives without fear of an attack. Here's a rundown of inhaler types, with tips on proper use.

By Mayo Clinic staff

Inhalers have transformed asthma treatment. They enable children and adults with asthma to deliver medicine directly to their lungs nearly anytime and anywhere. A variety of inhalers are available to help relieve or control asthma symptoms.

Types of inhalers

Inhalers are hand-held portable devices that deliver medication directly to the lungs. A variety of inhalers exist, but they basically fall into two categories:

Metered dose inhalers
These inhalers use a chemical propellant to force a measured dose of medication out of the inhaler. They consist of a pressurized canister containing medication, a mouthpiece and a metering valve that dispenses the correct dose of medication. The medication is released either by squeezing the canister or by inhaling. You may find it easier to use a hand-actuated inhaler with a spacer — a short tube that attaches to the inhaler. Using a hand-actuated inhaler to release the medication into the chamber gives you time to inhale more slowly. It decreases the amount of medicine that's deposited on the back of your throat and increases the amount that ultimately reaches your lungs.

Some metered dose inhalers have counters so that you know how many doses remain. If there is no counter, you have to track of the number of doses you've used so that you know when the inhaler is out of medication.

The chemical propellant in metered dose inhalers has traditionally been a chlorofluorocarbon (CFC). But after an international agreement to ban CFCs because they damage the ozone layer, other propellants such as hydrofluoroalkane (HFA) are now used instead. The dose of medication released by an HFA inhaler may feel softer and warmer than the dose released by a CFC inhaler. If you're used to a CFC inhaler, it may not seem like a complete dose — even though the medication is reaching your lungs.

Dry powder inhalers
These inhalers don't use a chemical propellant to push the medication out of the inhaler. Instead, the medication is released by breathing in more quickly than you would with a traditional metered dose inhaler.

Some people find dry powder inhalers easier to use than the conventional pressurized metered dose inhalers because hand-lung coordination isn't required. Some models require operating a cocking device that requires dexterity. Available types include a dry powder tube inhaler, a powder disk inhaler and a single-dose dry powder disk inhaler. Spacers shouldn't be used with dry powder inhalers.

Comparing inhaler types
Choosing the right kind of inhaler for you depends on several factors, such as your hand-breath coordination, your dexterity, whether you can take a deep, fast breath, and what types of medication you need. The chart below can help you understand the pros and cons of each type. Work with your doctor to find the best inhaler for your needs.

Medications delivered through inhalers

Inhalers are used to deliver a variety of asthma medications — some that assist with long-term control and others that provide quick relief of symptoms. Some medications may only be available in certain inhaler types. Inhaled asthma medications include:

• Short-acting bronchodilators. These medications, including albuterol (Proventil, Ventolin) and pirbuterol (Maxair), provide immediate relief of asthma symptoms.
• Long-acting bronchodilators. These medications relieve asthma symptoms for longer periods of time. They include salmeterol (Serevent) and formoterol (Foradil).
• Corticosteroids. Used long term to prevent asthma attacks, these medications include beclomethasone dipropionate (Qvar), fluticasone (Flovent), budesonide (Pulmicort), triamcinolone acetonide (Azmacort) and flunisolide (Aerobid).
• Cromolyn or nedocromil. These nonsteroidal medications are used long term to prevent inflammation.
• Corticosteroid plus long-acting bronchodilator. This medication combines a corticosteroid and a long-acting bronchodilator (Advair, Symbicort).

Inhalers may come with slightly different instructions. Follow those instructions carefully and ask your doctor for a demonstration.

The importance of using inhalers properly

It's important that you use your inhaler correctly so that the medication reaches your lungs. Carefully follow the instructions. And ask a doctor, nurse or pharmacist for a demonstration. Use the inhaler in front of this person and ask for feedback. Then practice at home in front of a mirror.

If you're unable to use an inhaler, a nebulizer may be an option. Nebulizers are designed for those who can't use an inhaler, such as infants, young children and those who are seriously ill. The device works by converting medication into a mist and delivering it through a mask that you wear over your nose and mouth.

Using an inhaler is just one part of your asthma treatment plan, which may also include checking your lung function with a peak flow meter, eliminating asthma triggers and exercising. But knowing what types of inhalers are available and how to use them can help you better manage your asthma and get the most from your treatment.
