What Its Like to Breath Again
Asthma is a chronic lung condition where the lung tissues go hypersensitive to external stimuli. This can lead to symptoms such every bit breathlessness, chest tightness, wheezing and coughing. In the United States, there are over 5 million children and xx meg adults with asthma, which is about seven–viii% of the overall population. Of these folks, over 40% have had an asthma attack in the last 12 months. Although asthma can be life-threatening, attacks can be prevented with correct use of inhalers — and fast-acting, inhaled medications.
Here, nosotros'll explore different types of inhalers and when to use them. Moreover, nosotros'll provide some helpful tips to help yous make the near of your handling.
What Is an Inhaler?
An inhaler is a portable, handheld device that'southward designed to exist small-scale enough to fit in your hand and in your bag, so it may exist carried around with yous all of the time. Inhalers contain medication in powdered form that is delivered direct into the airways as a mist or spray, through inhalation. Typically, inhalers require a prescription, unlike tablets. But they also avowal many advantages: in addition to being fast-acting, they can be administered in any setting.
It'southward important to annotation that there are several different types of inhalers. Depending on the frequency and intensity of your symptoms, your medico may recommend dissimilar types of inhalers. Every bit with all types of medications, it'southward important to understand when and how to properly use the asthma inhaler that's correct for you.
Types of Inhaled Medications
Asthma inhaler medications can exist broadly divided into preventers and relievers.
- Preventers are taken on a daily ground to control the disease and foreclose lung inflammation from taking over and causing an asthma attack
- Relievers, or rescue inhalers, are taken when symptoms worsen, for instance feeling more incoherent, chest tightness or wheezing, or during an asthma assault.
Bronchodilators
Bronchodilator medications, as the name suggests, cause dilation (widening) of the airways, allowing for a amend airflow and relieving symptoms of breathlessness, tightness and wheeze.
Nigh people with asthma volition carry some kind of bronchodilator inhaler called a short-acting beta agonist (SABA). SABA inhalers human activity on the beta receptors in smooth muscle of the airways, triggering relaxation of the muscles and a widening of the tubes of the lungs. Examples of SABA medications include salbutamol (eastward.thousand. Ventolin), albuterol (east.1000. ProAir RespiClick) and levalbuterol. Their effects are felt chop-chop, however wear off quite rapidly, and you may need further doses to relieve your symptoms. If you find yourself using your reliever inhaler often, consult your doc who may recommend a preventer inhaled therapy.
Inhaled long-acting beta agonists (LABA) also open the airways by relaxing the polish muscles around the airways even so concluding longer than the short-acting version. Examples of LABA medications are formoterol and salmeterol. LABA are typically used in combination with a corticosteroid inhaler.
Corticosteroids
Corticosteroid inhalers are the most common type of preventer medication that is typically taken on a daily basis. Steroids assist to reduce inflammation in the airways and keep the airways clear of mucus. Not anybody with asthma needs a steroid inhaler. Examples include beclomethasone (east.g. Qvar), fluticasone (due east.one thousand. Flovent) and mometasone (e.g. Asmanex).
Anticholinergic Medications
Long-acting muscarinic antagonists (LAMA) or anticholinergics target a different receptor (the muscarinic receptor) and forbid the smooth musculus contraction that tin atomic number 82 to airway tightening. LAMA tin can both relieve symptoms, and provide ongoing prevention, and are typically used equally a preventer in combination with a bronchodilator. Examples include tiotropium (east.g. Spiriva), ipratropium (e.grand. Atrovent), aclidinium bromide (e.grand. Genuair), umeclidinium (e.g. Incruse) and glycopyrrolate (Seebri Neohaler).
Combination Inhalers
Depending on the severity and frequency of your symptoms, each type of inhaler may play a role in treating your asthma. Other asthma inhalers may contain a combination of medications, such as ii types of bronchodilators or a combination of long-acting bronchodilators and steroids to help treat both inflammation and narrowing of the airways.
Common combinations are:
- Budesonide (a steroid) in combination with formoterol (a LABA), marketed as e.g. Symbicort or Pulmicort
- Fluticasone (a steroid) and vilanterol (a LABA), marketed every bit Breo Ellipta
- Fluticasone with both umeclidinium, and vilanterol, marketed equally Trelegy Ellipta
Speak to your md to learn what regime, if any, is right for you lot.
Types of Devices
Inhalers
- Metered dose inhalers (MDIs) give the medicine in a spray form (aerosol). These typically accept a pressurized canister that'southward pushed down to deliver the spray, at the same time as the user breathes in.
- Jiff actuated inhalers (BAIs), or autohalers, release a spray of medicine when y'all begin to inhale. They are oft easier to utilise as yous don't need to press annihilation to evangelize the medication, it's automatically released when you breath in.
- Dry powder inhalers (DPIs) administer a dry pulverization medicine instead of a spray.
Nebulizers
Nebulizers incorporate liquid medication which is delivered to the airways via a fine mist, using pressurized air or oxygen via a mask or tubing organisation. These are often used in the hospital setting and tin can deliver a high concentration of medication over several minutes or even hours.
Spacers
A spacer, sometimes referred to as an aero-chamber, is a small tube that can exist attached between the inhaler and mouthpiece on certain metered dose inhalers. Attaching a spacer to the inhaler makes information technology easier to take the medication. One time the canister is pressed, the medication is trapped inside the chamber, allowing the patient to inhale slowly and deeply. This helps the medication infiltrate deeper into the airways and makes treatment more constructive.
A spacer also makes it easier to give young children an inhaler. These spacers have a mask on i stop that fits over the kid'due south nose and mouth as they inhales.
How to Use Your Inhaler
Your medico should provide you lot with instructions on how to use your inhaler since different models are often used in a slightly unlike mode.
Metered Dose Inhalers (MDI)
A MDI requires you to press to release the medication, at the same time as breathing in. Y'all should remove the cap and milk shake the device well. Some devices also accept a dose counter on them, then bank check in that location is sufficient medication left. Breathe out and secure your lips around the mouthpiece. Start to breathe in slowly, whilst simultaneously pressing down on the acme of the canister to release the medication. Continue to breathe in until you have taken a total breath. Hold your breath for around 5 seconds, or as long as is comfortable. Exhale out normally. Your physician may take advised yous to accept ii "puffs", so repeat this process if that is the case.
If you lot find you're struggling to coordinate animate and pressing at the aforementioned time, your device may be suitable for utilise with a spacer, which traps the medication in a plastic chamber, then y'all don't have to worry virtually pressing and breathing at the same time.
Jiff Actuated Inhalers (BAIs)
These devices practice not require you to press annihilation at the aforementioned time as animate. They volition often come with a dose counter, and a comprehend that needs to be pressed until a click is heard, this "primes" the inhaler set up to release the dose. Breathe out fully, then place your lips around the mouthpiece. Have a deep continuous breath in, the medication will automatically be dispersed. Hold your jiff for 5 seconds or however long is comfortable. Be certain to "reset" the counter if more than one dose is required.
Tips for Inhaler Use
Always carry your reliever inhaler with you. Even if you are just popping out for a couple of minutes, information technology's sometimes unpredictable when chest tightness volition strike. For this reason, consider having spare inhalers in places you frequent, such as your car or function, but in case you forget to bring ane with you. Other important inhaler-use tips, include the following:
- Inform your friends and family that you lot accept asthma and show them how to assist yous in administering your inhaler
- Perform frequent checks on your inhaler for "use past" date and how much of the medication is left
- It's often easier to take a deep breath when standing upward rather than sitting downwards
- If you are using your reliever inhaler more often, see your doctor
- Attend your doctor for a review of your asthma at least once per year
- Keep a diary of symptoms, this may help you to identify triggers for chest tightness or coughing
- Create an "asthma programme" which details what to do if you feel your asthma is getting worse
Environmental Concerns About Inhalers
Chlorofluorocarbons (CFCs) were once used every bit propellants in diverse aerosol sprays including asthma inhalers. Because the main chemical chemical compound is believed to damage the Earth'southward ozone layer, the U.S. government began regulating the use of chlorofluorocarbons in the 1970s. While they were banned in products like hairspray, chlorofluorocarbons were allowed in medical products including asthma inhalers until fairly recently.
In the spring of 2010, the U.Due south. Food and Drug Administration (FDA) announced plans to stage out asthma inhalers that incorporate chlorofluorocarbons. In response, some inhaler manufacturers have switched to hydrofluoroalkane, a propellant that's believed to exist safer for the environment.
Adjacent Steps
Asthma can interfere with daily activities and impact your quality of life, simply the right asthma inhaler can help you manage your symptoms. However, asthma medication is just effective if patients use their inhalers properly. Be sure to speak with your doctor not only about your symptoms, simply most proper inhaler employ likewise.
