Around 3.8 million people in the UK have not been instructed on correct inhaler use, according to research by charity Asthma + LUNG UK. The survey found that approximately 70% of the UK's 5.4 million asthma sufferers lack basic care elements, including guidance on optimizing inhaler use. Millions more use inhalers for COPD and other chronic lung diseases. This education gap is believed to contribute to the four asthma deaths that occur daily in the UK, many of which are deemed avoidable.
New guide from UK Inhaler Group
The findings have prompted the UK Inhaler Group (UKIG) to issue a new guide aimed at improving inhaler technique. Dr Katherine Hickman, a GP and respiratory specialist, shared tips to promote the guide. Among the key recommendations is the use of spacers with pressurised metered-dose inhalers (pMDIs), which account for around 70% of inhalers in the UK. The NHS states that spacers are 'more effective' at delivering medication. A study in the European Respiratory Journal found that not using a spacer can result in as little as half the intended dose being delivered. 'Spacer devices play a critical role in asthma care, mitigating technique, coordination and throat deposition issues, which we know impact both adults and children,' Dr Hickman said. 'We need to spread the message about spacer use as far and wide as possible.'
Spacer suitability and proper technique
Spacers are not suitable for all inhaler types. Dry powder inhalers (DPIs) and breath-actuated inhalers (BAIs) do not require a spacer, according to Asthma + LUNG UK. Patients should consult their GP or pharmacist to determine if a spacer is appropriate. Other essential tips include shaking the inhaler well before each use to ensure proper mixing of medication. Liam Clutterbuck, from Trudell Medical UK, explained that failing to shake can result in uneven distribution, making the inhaler less effective. The NHS recommends waiting 30 to 60 seconds between puffs and shaking the inhaler each time.
Inhalation technique and breath holding
Inhaling slowly and deeply is crucial. Exhale fully first, then inhale steadily over 3 to 5 seconds rather than taking a fast, sharp breath. This allows medicine to travel deep into the lungs rather than depositing in the mouth or throat. Asthma + LUNG UK also recommends holding your breath for five to 10 seconds after inhaling to let the medicine settle in the airways. Ensuring a tight seal around the mouthpiece or facemask prevents medication from leaking out, maximising the dose reaching the airways.
