Bronchodilator Pronunciation: Bron-ko-di-la-tor (ˈbräŋ-kō-ˈdī-lā-tər)

Definition: Bronchodilators are a type of medication that relaxes and opens the airways (bronchi) in the lungs, making it easier for a person to breathe.

What are Bronchodilators?


Bronchodilators are medications often used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). These medications can be administered in several ways, including inhalation (through a metered dose inhaler or nebulizer) or orally.

Key Facts About Bronchodilators:

  • Bronchodilators work by relaxing the muscles that tighten around your airways (bronchi), allowing them to open up for easier breathing.
  • They are used to provide relief from breathing difficulties associated with conditions such as asthma, COPD, and other respiratory diseases.
  • There are three main types of bronchodilators: beta-agonists, anticholinergics, and theophylline.
  • Side effects of bronchodilators can include tremors, palpitations, nervousness, and nausea. However, not everyone experiences these side effects, and they may diminish with regular use.
  • It’s important to use bronchodilators as prescribed by your healthcare provider, as overuse can lead to decreased effectiveness and increased side effects.

How to reduce the risk of bronchospasm (constriction of the airways)

Avoid triggers If you have a known trigger for bronchospasm, such as allergens, exercise, cold air, or certain medications, avoidance is the best prevention strategy.

Proper use of medication If you have been prescribed a bronchodilator for prevention or treatment of bronchospasm, ensure you use it as directed by your healthcare provider. Not using the medication properly can increase the risk of bronchospasm.

Regular follow-up with your healthcare provider Regular visits to your healthcare provider will help monitor your condition and make any necessary changes to your medication or treatment plan.

Bronchodilators Symptoms & Causes

What are the symptoms that necessitate the use of Bronchodilators?

Bronchodilators are often used when individuals experience symptoms such as:

  • Shortness of breath
  • Wheezing
  • Coughing
  • Chest tightness

What causes the need for Bronchodilators?

Conditions that may necessitate the use of bronchodilators include:

  • Asthma: This chronic condition causes inflammation and narrowing of the bronchial tubes, leading to difficulty breathing.
  • Chronic Obstructive Pulmonary Disease (COPD): This group of lung diseases, which includes chronic bronchitis and emphysema, causes airflow blockage, making it hard to breathe.
  • Bronchiectasis: This condition, which causes the airways to become abnormally wide, often leads to respiratory infections and breathing difficulties.

Bronchodilators Diagnosis & Treatments

How is the need for Bronchodilators diagnosed?

A healthcare provider may diagnose the need for bronchodilators based on the symptoms, medical history, and physical examination of a patient. Pulmonary function tests, which measure how well your lungs work, may also be used.

How are Bronchodilators administered?

Bronchodilators can be administered in several ways:

  • Metered Dose Inhalers (MDIs): These handheld devices deliver a specific amount of medication in aerosol form directly to the lungs.
  • Nebulizers: These machines convert liquid medication into a mist that can be inhaled deep into the lungs.
  • Oral Medication: Some bronchodilators can be taken by mouth in pill or liquid form.

How do we use Bronchodilators?

Healthcare providers often prescribe bronchodilators to help manage the symptoms of chronic respiratory conditions. By opening up the airways, these medications can provide relief from symptoms such as shortness of breath, wheezing, and coughing, thereby improving the quality of life for those living with these conditions. It’s crucial to use bronchodilators as prescribed by your healthcare provider to ensure their effectiveness and minimize any potential side effects.

What do bronchodilators have to do with CPR?

Bronchodilators are primarily used to treat conditions like asthma and chronic obstructive pulmonary disease (COPD) that cause difficulty breathing due to narrowing and inflammation of the airways. While not directly used in the process of cardiopulmonary resuscitation (CPR), understanding of their use and effect on a patient’s respiratory system can have indirect implications for CPR.

  1. Preexisting Respiratory Conditions: If a patient has a preexisting respiratory condition like asthma or COPD, the use of bronchodilators could be part of their long-term treatment. A person performing CPR should be aware of these conditions, as difficulty breathing or a severe asthma attack can lead to a cardiac arrest. Having this information might provide important context for understanding the individual’s medical emergency.
  2. Airway Management: A key component of CPR is ensuring the person’s airway is open so they can receive oxygen. Bronchodilators help open up the airways and could therefore be utilized in the broader management of the person’s airway before or after the CPR process, but not during the actual CPR. It’s important to note that administration of bronchodilators should be left to trained medical professionals, as improper use could potentially harm the individual.
  3. In a Hospital Setting: In a hospital setting, healthcare professionals may administer bronchodilators to a patient who has been resuscitated following CPR, especially if they have a known respiratory condition. This would be part of the post-resuscitation care to manage and stabilize the patient’s condition.

It’s crucial to remember that while bronchodilators have a role in managing respiratory conditions, they do not replace the immediate need for CPR in a cardiac arrest situation. If someone’s heart has stopped, the priority is to perform chest compressions and provide rescue breaths or use an automated external defibrillator (AED) if available, rather than focusing on giving the person their regular medication.
