Do You Use Your Asthma Inhaler Correctly?

November 27, 2020 2 min read

Inhalers play a leading role in helping asthma treatments and Chronic Obstructive Pulmonary Disease (COPD). Indeed, an inhaler can even be lifesaving if used properly in accordance with asthma guidelines! But to do their job of delivering medication, it is important that you use your asthma inhaler correctly. So it is concerning to read a study from the University of Chicago that shows how the majority of patients do not use their asthma inhaler as intended.

The researchers asked 100 adults who had been hospitalised for either asthma or COPD (so we can assume they had a severe disease) to demonstrate how they actually used their inhalers. Most of them made some kind of error. The good news is that it does not take very long for you to learn how to use your asthma inhaler in the right way.

There are two types of asthma inhalers - preventers and relievers. A preventer protects the airways and reduces the risk of an asthma attack. A reliever is the one you use when you are having an attack - it gets rid of the asthma symptoms. There are several different designs of the inhaler. This study involved a metered-dose inhaler and a Diskus inhaler. The metered-dose inhaler is mainly used as both a preventer and reliever while the Diskus inhaler is used as a preventer. The important point is that they are used in different ways. Since many patients with asthma will have both types, it’s important to be aware of the differences and how to use your asthma inhaler. With the metered dose inhaler, you have to inhale slowly. With the Diskus, you inhale sharply. In this study, metered-dose inhalers were used incorrectly nearly nine out of ten times, and Diskus inhalers seven out of ten times. The main error was failing to breathe out completely before using the inhaler.

Eyesight seemed to be an issue as well. Nearly all of those with vision problems did not use the Diskus inhaler correctly, compared to more than half of those with no vision problems. It might be that people with poor eyesight have difficulty reading the instructions for the inhaler, as these tend to be written in small print.

Half of the participants were then taken aside and given a lesson on how to use the inhaler. Within a very short time, all had mastered the technique for both types of inhaler.

Next, to the other best practice asthma treatments, it is so important to be using your medication correctly if you suffer with asthma or COPD. If your symptoms are not well controlled, the reason could be that you use your asthma inhaler incorrectly. Ideally, your doctor should have shown you how, but this doesn’t always happen. Don’t be afraid to ask questions if you are not sure and don’t assume that you are doing it right!

The VAX AP03 air purifier is a basic mid-range air purifier with basic features. The timer is simple, but the filter life indicator seems flawed. It is hard to imagine the odour/carbon filter to be anything else then ineffective in capturing and retaining gases and chemicals.
