Many people with asthma can use their inhalers incorrectly, which increases their risk of asthma attacks, according to new research published in the Journal of Allergy and Clinical Immunology: In Practice.

Propeller Health investigators, in collaboration with the University of Colorado School of Medicine and the Children's Hospital of Colorado, collected data on 7558 patients and found that 84% of patients took fewer 30 seconds between the first and the second puff of their rescue or controller. inhaler. In addition, 67% waited less than 15 seconds between inhalations. Only 16% of patients waited more than 30 seconds between puffs, the minimum time required to complete the recommended steps.

The recommended dosage of asthma medications requires two inhalations of the inhaler, and many instructions to patients recommend that a patient expire completely before inhaling, inhaling slowly and deeply the drug, hold his breath for 10 seconds, then wait before his time. next inhalation. These different steps should take between 30 and 60 seconds, according to the authors.

According to the press release, patients aged 4 to 11 years had the highest acceptable rate of time between the use of an inhaler, while those aged 18 to 29 had the lowest.

"We hope that with this data from digital drugs, patients and physicians will stimulate a new momentum to solve the known problems related to the inadequacy of the inhalation technique, which we know, can have a significant impact on how patients feel about their disease, "said Stanley Szefler, MD. Director of the Pediatric Asthma Research Program at the Sleep Medicine and Respirology Sleep Section of the Pediatric Respiratory Institute of the Colorado Children's Hospital, in a prepared statement .
