Reduction of Asthma Attacks Binds to Laminar Air Flow Device

With the pollution in rise anywhere, most especially in the cities, it is not shocking to known that respiratory disorders are now common. In fact, without us knowing, there are as many people having respiratory problems than we thought. Common colds, allergy, rhinitis, bronchitis and other upper and lower respiratory ailments are now being suffered by both young and adult population.

Asthma, in particular, is one of these respiratory disorders that occurs in frequent attacks due to exposure to allergens or irritants that causes the airway to narrow and breathing to be impaired. The inflammation of the airway lining produces wheezing as the patient breathes.

Common symptoms may include difficulty in breathing, cough, shortness of breath, intercostals retractions (evident inward movement of the rib muscles) and even chest pain in severe cases. There are lots of management that can control asthma attacks and exacerbation; drugs like bronchial dilators, decreasing mucus production drugs (Leukotriene inhibitors), and corticosteroids (prevents inflammation of airway lining). However, avoiding of the pollutants and allergens are still the main line of defense and prevention of asthma.

About 18 years running in the market, Temperature-controlled laminar airflow (TLA) is a device termed to as air shower displacing air particles in the breathing zone of patients. The device is placed at the head part of the bed and looks like a circular beam. Somewhat slightly cooler air and filtered air are being delivered by the air shower device with downward pressure causing the particles and allergens to be conveyed in a different direction other that upward moving to be inhaled by the patient.

John Warner, MD, from Imperial College London, and colleagues in Thorax made known to public that the Temperature-controlled laminar airflow (TLA) reduces the occurrence of atopic asthma and improvement in the quality of life of certain patients after one year of night exposure to Temperature-controlled laminar airflow (TLA).

Asthma Quality of Life or Pediatric Asthma Quality of Life Questionnaires (AQLQ) was used and found out better results among children aging 12 year below and above. The study includes about 312 participants with uncontrolled atopic asthma and was exposed during their sleeping time on the Temperature-controlled laminar airflow (TLA) with a programmed 12 hours running time.

“The reason that nocturnal TLA is successful where so many other approaches have failed may be the profound reduction in inhaled allergen exposure which this treatment achieves.” explained by the authors due to some adverse effects that had developed even it was not  directly related with the treatment regimen.

They also acknowledged the inadequacy of their study as to the small number of population that they used and the self-reported quality of life as an effect of TLA.
