Is Inspiratory Flow Rate (IFR) appropriate for the puffers patients use for their lung conditions, and will training them to achieve the appropriate IFR improve their shortness of breath and reduce their need for health services?

Brief summary

Many patients with lung disease who use inhalers (puffers) are unable to generate enough strength when breathing in through their puffers. Often, they breathe too hard with some puffers. This breathing strength is generally known as the Inspiratory Flow Rate (IFR). Inappropriate IFR leads to sub-optimal use of puffers, compromising the effectiveness of patients' treatment. This study aims to know how common this problem is and to test the idea that training patients to achieve appropriate IFR leads to better outcomes. These outcomes include improved breathing, better quality of life, and reduced emergency department visits, as well as shorter hospital stays.

Interventions

Training patients to achieve an appropriate Inspiratory Flow Rate (IFR) for the Inhaler Device they use. Verbal training is provided by a pharmacist while utilising an inspiratory flow meter, and is followed up by individualised written instructions on how to achieve the appropriate IFR range for each of the inhalers a patient is using. Verbal training would take between 5-10 minutes until the patient achieves appropriate IFR or the pharmacist determines that the patient is unable to achieve suc

Verbal training would take between 5-10 minutes until the patient achieves appropriate IFR or the pharmacist determines that the patient is unable to achieve such IFR. Written instructions should be provided 1-2 days after verbal training is offered. All training is offered only once to participants.
