Spacers are medical devices used in conjunction with inhalers to deliver medication more effectively to the lungs. They are commonly used to treat respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis. Spacers help to improve the delivery of medication by slowing down the aerosol particles, allowing them to be inhaled more deeply into the lungs.
History of Spacers
The first spacers were developed in the 1970s, and they were initially made of metal or plastic. These early spacers were often cumbersome and difficult to use. However, with advancements in technology, modern spacers are now made of lightweight materials, such as plastic or silicone, and are designed to be easy to use and clean.
Types of Spacers
There are several types of spacers available, including:
- Valved holding chambers (VHCs): VHCs are the most common type of spacer. They have a valve that allows the user to inhale the medication but prevents exhaled air from entering the spacer.
- Non-valved spacers: Non-valved spacers do not have a valve and rely on the user’s breathing to draw the medication into the lungs.
- Aerochambers: Aerochambers are a type of VHC that is designed for use with metered-dose inhalers (MDIs).
- Nebuliser spacers: Nebuliser spacers are designed for use with nebulisers and are used to deliver medication to the lungs.
How to Use a Spacer
Using a spacer is a simple process that requires some basic steps. Here’s a step-by-step guide on how to use a spacer:
- Prepare the spacer: Before using the spacer, make sure it is clean and free of any debris.
- Shake the inhaler: Shake the inhaler well before attaching it to the spacer.
- Attach the inhaler: Attach the inhaler to the spacer according to the manufacturer’s instructions.
- Inhale the medication: Inhale the medication slowly and deeply through the spacer.
- Hold your breath: Hold your breath for 10 seconds to allow the medication to be absorbed into the lungs.
- Exhale slowly: Exhale slowly and repeat the process as directed by your healthcare provider.
Benefits of Spacers
Spacers have several benefits, including:
- Improved medication delivery: Spacers help to improve the delivery of medication by slowing down the aerosol particles, allowing them to be inhaled more deeply into the lungs.
- Increased efficacy: Spacers can increase the efficacy of medication by ensuring that more of the medication is delivered to the lungs.
- Reduced side effects: Spacers can reduce the risk of side effects by minimising the amount of medication that is deposited in the mouth and throat.
- Easy to use: Spacers are easy to use and require minimal training.
Common Spacer Medications
Some common medications used with spacers include:
- Bronchodilators: Bronchodilators, such as albuterol and salmeterol, help to relax the muscles in the airways and improve airflow to the lungs.
- Corticosteroids: Corticosteroids, such as fluticasone and budesonide, help to reduce inflammation in the airways and improve lung function.
- Combination inhalers: Combination inhalers, such as fluticasone-salmeterol and budesonide-formoterol, combine a bronchodilator and a corticosteroid in a single inhaler.
Spacer Safety Precautions
When using a spacer, it is essential to follow safety precautions to minimise the risk of side effects and ensure effective treatment. Here are some safety precautions to follow:
- Read the instructions carefully: Before using a spacer, read the instructions carefully to ensure that you understand how to use it correctly.
- Use the spacer as directed: Use the spacer as directed by your healthcare provider, and do not exceed the recommended dose.
- Clean the spacer regularly: Clean the spacer regularly to prevent the growth of bacteria and other microorganisms.
- Monitor your symptoms: Monitor your symptoms regularly and adjust your treatment plan as needed.
_Conclusion_
Spacers are medical devices used in conjunction with inhalers to deliver medication more effectively to the lungs. They are commonly used to treat respiratory conditions such as asthma, COPD, and cystic fibrosis. By following safety precautions and using the spacer correctly, individuals can minimise the risk of side effects and ensure effective treatment.
