Never Again Now I See Never Again Now I Breathe
Asthma is a chronic lung condition where the lung tissues become hypersensitive to external stimuli. This can lead to symptoms such as breathlessness, chest tightness, wheezing and coughing. In the Us, there are over 5 one thousand thousand children and 20 million adults with asthma, which is about 7–viii% of the overall population. Of these folks, over 40% have had an asthma assault in the last 12 months. Although asthma can be life-threatening, attacks tin can be prevented with correct use of inhalers — and fast-acting, inhaled medications.
Here, we'll explore different types of inhalers and when to use them. Moreover, we'll provide some helpful tips to help you make the most of your treatment.
What Is an Inhaler?
An inhaler is a portable, handheld device that's designed to be pocket-sized enough to fit in your hand and in your bag, so information technology may exist carried around with yous all of the fourth dimension. Inhalers contain medication in powdered form that is delivered direct into the airways equally a mist or spray, through inhalation. Typically, inhalers require a prescription, dissimilar tablets. But they besides boast many advantages: in improver to existence fast-acting, they can be administered in whatever setting.
It's important to note that there are several different types of inhalers. Depending on the frequency and intensity of your symptoms, your doctor may recommend different types of inhalers. Equally with all types of medications, it's of import to understand when and how to properly use the asthma inhaler that's correct for y'all.
Types of Inhaled Medications
Asthma inhaler medications can be broadly divided into preventers and relievers.
- Preventers are taken on a daily footing to control the affliction and prevent lung inflammation from taking over and causing an asthma attack
- Relievers, or rescue inhalers, are taken when symptoms worsen, for case feeling more breathless, chest tightness or wheezing, or during an asthma attack.
Bronchodilators
Bronchodilator medications, as the proper name suggests, cause dilation (widening) of the airways, allowing for a better airflow and relieving symptoms of breathlessness, tightness and wheeze.
Most people with asthma will acquit some kind of bronchodilator inhaler called a short-interim beta agonist (SABA). SABA inhalers human activity on the beta receptors in shine muscle of the airways, triggering relaxation of the muscles and a widening of the tubes of the lungs. Examples of SABA medications include salbutamol (east.g. Ventolin), albuterol (e.g. ProAir RespiClick) and levalbuterol. Their effects are felt rapidly, still wear off quite quickly, and you may demand farther doses to relieve your symptoms. If yous find yourself using your reliever inhaler often, consult your doctor who may recommend a preventer inhaled therapy.
Inhaled long-acting beta agonists (LABA) also open up the airways past relaxing the smoothen muscles around the airways however last longer than the brusk-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 well-nigh 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 articulate of mucus. Non everyone with asthma needs a steroid inhaler. Examples include beclomethasone (e.g. Qvar), fluticasone (e.chiliad. Flovent) and mometasone (east.thousand. Asmanex).
Anticholinergic Medications
Long-interim muscarinic antagonists (LAMA) or anticholinergics target a different receptor (the muscarinic receptor) and prevent the smooth muscle contraction that can lead to airway tightening. LAMA tin can both relieve symptoms, and provide ongoing prevention, and are typically used as a preventer in combination with a bronchodilator. Examples include tiotropium (e.k. Spiriva), ipratropium (e.g. Atrovent), aclidinium bromide (e.g. Genuair), umeclidinium (eastward.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 incorporate a combination of medications, such every bit 2 types of bronchodilators or a combination of long-acting bronchodilators and steroids to aid treat both inflammation and narrowing of the airways.
Common combinations are:
- Budesonide (a steroid) in combination with formoterol (a LABA), marketed as east.g. Symbicort or Pulmicort
- Fluticasone (a steroid) and vilanterol (a LABA), marketed as Breo Ellipta
- Fluticasone with both umeclidinium, and vilanterol, marketed as Trelegy Ellipta
Speak to your doctor to learn what regime, if any, is right for you lot.
Types of Devices
Inhalers
- Metered dose inhalers (MDIs) requite the medicine in a spray course (aerosol). These typically have a pressurized canister that's pushed downwardly to deliver the spray, at the same time as the user breathes in.
- Breath actuated inhalers (BAIs), or autohalers, release a spray of medicine when you begin to inhale. They are often easier to apply as y'all don't need to press anything to deliver 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 contain liquid medication which is delivered to the airways via a fine mist, using pressurized air or oxygen via a mask or tubing system. These are often used in the hospital setting and tin evangelize a high concentration of medication over several minutes or even hours.
Spacers
A spacer, sometimes referred to equally an aero-chamber, is a small tube that tin can be attached between the inhaler and mouthpiece on certain metered dose inhalers. Attaching a spacer to the inhaler makes it easier to take the medication. Once the canister is pressed, the medication is trapped within the chamber, allowing the patient to inhale slowly and deeply. This helps the medication infiltrate deeper into the airways and makes handling more effective.
A spacer also makes information technology easier to give young children an inhaler. These spacers accept a mask on one cease that fits over the kid's nose and rima oris every bit they inhales.
How to Utilise Your Inhaler
Your physician should provide you with instructions on how to use your inhaler since different models are often used in a slightly dissimilar way.
Metered Dose Inhalers (MDI)
A MDI requires yous to press to release the medication, at the same time as breathing in. You lot should remove the cap and shake the device well. Some devices likewise take a dose counter on them, so check there is sufficient medication left. Breathe out and secure your lips effectually the mouthpiece. Start to breathe in slowly, whilst simultaneously pressing down on the summit of the canister to release the medication. Continue to breathe in until you have taken a full jiff. Hold your breath for around 5 seconds, or as long equally is comfortable. Breathe out normally. Your doctor may take advised you to have two "puffs", so repeat this process if that is the case.
If you find you're struggling to coordinate breathing and pressing at the same time, your device may exist suitable for use with a spacer, which traps the medication in a plastic chamber, then y'all don't take to worry almost pressing and breathing at the same time.
Breath Actuated Inhalers (BAIs)
These devices do not require you to printing anything at the aforementioned time equally breathing. They will often come with a dose counter, and a comprehend that needs to be pressed until a click is heard, this "primes" the inhaler ready to release the dose. Breathe out fully, then identify your lips around the mouthpiece. Take a deep continuous jiff in, the medication will automatically be dispersed. Concord your breath for 5 seconds or notwithstanding long is comfortable. Be sure to "reset" the counter if more than i dose is required.
Tips for Inhaler Use
E'er carry your reliever inhaler with y'all. Even if you are just popping out for a couple of minutes, information technology'southward sometimes unpredictable when chest tightness will strike. For this reason, consider having spare inhalers in places you lot frequent, such equally your auto or office, just in instance you forget to bring i with y'all. Other important inhaler-use tips, include the following:
- Inform your friends and family that you lot have asthma and show them how to assist you in administering your inhaler
- Perform frequent checks on your inhaler for "use by" date and how much of the medication is left
- It's often easier to have a deep jiff when standing up rather than sitting downwardly
- If you lot are using your reliever inhaler more than ofttimes, see your doctor
- Attend your medico for a review of your asthma at least once per year
- Go on a diary of symptoms, this may assist you to identify triggers for chest tightness or cough
- Create an "asthma plan" which details what to do if you feel your asthma is getting worse
Environmental Concerns About Inhalers
Chlorofluorocarbons (CFCs) were one time used as propellants in various aerosol sprays including asthma inhalers. Considering the master chemic compound is believed to damage the Earth'southward ozone layer, the U.South. 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 bound of 2010, the U.South. Food and Drug Administration (FDA) announced plans to phase out asthma inhalers that contain chlorofluorocarbons. In response, some inhaler manufacturers have switched to hydrofluoroalkane, a propellant that's believed to be safer for the environment.
Next Steps
Asthma can interfere with daily activities and affect your quality of life, only the right asthma inhaler can assistance yous manage your symptoms. Notwithstanding, asthma medication is only effective if patients utilise their inhalers properly. Be sure to speak with your doctor not only nigh your symptoms, but near proper inhaler use every bit well.
