A simple device that filters out airborne asthma triggers during sleep can ease persistent symptoms during the day and improve life quality, according to an Imperial College London study published online in Thorax.
Temperature controlled laminar airflow treatment (TLA) delivers a constant, cooled airflow in the patient’s breathing area.
The authors studied 281 patients with poorly controlled atopic asthma.
Of these, 189 slept with a TLA device above their bed and the rest a dummy device.
Those using the TLA device recorded significantly better quality of life scores after 12 months.
