Nocturnal temperature controlled laminar airflow for treating atopic asthma: a randomised controlled trial
OBJECTIVE To determine whether environmental control using nocturnal temperature controlled laminar airflow (TLA) treatment could improve the quality of life of patients with persistent atopic asthma. DESIGN Randomised, double-blind, placebo-controlled, parallel-group trial. Setting Nineteen European asthma clinics. PARTICIPANTS 312 patients aged 7-70 with inadequately controlled persistent...

متن کاملVentilation Rates and Airflow Pathways in Patient Rooms: A Case Study of Bioaerosol Containment and Removal.
Most studies on the transmission of infectious airborne disease have focused on patient room air changes per hour (ACH) and how ACH provides pathogen dilution and removal. The logical but mostly unproven premise is that greater air change rates reduce the concentration of infectious particles and thus, the probability of airborne disease transmission. Recently, a growing body of research sugges...
متن کاملAirflow resistance of airflow-regulating devices described by independent coefficients.
Rehabilitation after laryngectomy includes more and more the use of airflow-regulating devices such as shunt valves (SVs), tracheostoma valves (TSVs), and heat and moisture exchange (HME) filters. In determining the quality of those devices, airflow resistance is a very important factor. It is currently defined as pressure drop divided by airflow. However, for most applications, this definition...
متن کاملTemperature-controlled laminar airflow in severe asthma for exacerbation reduction (The LASER Trial): study protocol for a randomised controlled trial.
BACKGROUND Asthma affects more than 5 million patients in the United Kingdom. Nearly 500,000 of these patients have severe asthma with severe symptoms and frequent exacerbations that are inadequately controlled with available treatments. The burden of severe asthma on the NHS is enormous, accounting for 80 % of the total asthma cost (£1 billion), with frequent exacerbations and expensive medica...
