Using a spacer when administering albuterol for an asthma attack is important because it helps more of the medication reach the lungs where it is needed, rather than staying in the mouth or throat. The spacer acts as a holding chamber that slows down and holds the aerosol medication from the inhaler, allowing it to be breathed in slowly and deeply. This improves medication delivery to the small airways, enhances effectiveness, and reduces side effects like throat irritation or hoarseness that can occur if the medicine deposits in the mouth or throat. It also makes coordination between pressing the inhaler and breathing in easier, which is especially helpful during an asthma attack or for people who have difficulty using an inhaler properly. Key reasons for using a spacer include:
- More medication reaches the lungs instead of the mouth or throat.
- Medication particles slow down and break into smaller droplets for deeper lung penetration.
- Avoids spraying medicine too fast, which can cause it to hit the throat.
- Easier to coordinate inhaler use during shortness of breath.
- Reduces side effects, such as oral irritation or thrush.
- Particularly useful for children, elderly, and those who can't form a tight seal around the inhaler mouthpiece.
Studies show that spacers are as effective as nebulizers in delivering bronchodilator medication during acute asthma exacerbations but are more portable, convenient, less expensive, and have fewer systemic side effects.
