Bronchial Thermoplasty: A Novel Therapeutic Approach to Severe Asthma

Cited by 4 •
2010
Bronchial thermoplasty is a non-drug procedure for severe persistent asthma that delivers thermal energy to the airway wall in a precisely controlled manner to reduce excessive airway smooth muscle. Reducing airway smooth muscle decreases the ability of the airways to constrict, thereby reducing the frequency of asthma attacks.

This method aims at locating vertical subsurface defects. Here, we couple a laser with a spatial light modulator and trigger its video input to heat a sample surface deterministically with two anti-phased modulated lines while acquiring highly resolved thermal images. The defect position is retrieved from evaluating thermal wave interference minima.

For this study synchrotron radiation micro-tomography, a non-destructive three-dimensional imaging technique, is employed to investigate an entire microelectronic package with a cross-sectional area of 16 x 16 mm. Due to the synchrotron's high flux and brightness the sample was imaged in just 3 min with an 8.7 µm spatial resolution.
FAQs
Forced vital capacity describes the total amount of air exhaled during a forceful breathing maneuver, whereas forced expiratory volume in one second records how much air leaves the lungs during the first second. Considering both measurements provides information about lung volume and the speed of airflow rather than relying on a single measurement.
The recorded airflow and volume values can show whether breathing is more consistent with an obstructive or restrictive pattern. This distinction helps biologists and healthcare researchers interpret how lung function is affected and supports evaluation of respiratory conditions. The measurements provide an objective basis for identifying patterns that may not be apparent from symptoms alone.
Repeating measurements over time allows researchers or clinicians to track changes in pulmonary function rather than examining one isolated result. Trends can help show whether respiratory health is stable, worsening, or responding to treatment. This longitudinal approach is especially relevant when studying respiratory conditions or evaluating changes in lung function during ongoing investigations.
Spirometry supplies measurable airflow and volume data for investigating how the lungs function and how pulmonary health changes under different conditions. In biology research, these measurements can support studies of respiratory physiology and environmental effects on the lungs. They help connect observed respiratory changes with quantifiable alterations in lung performance.
The individual breathes forcefully into a spirometer, which captures airflow and volume during the breathing maneuver. The instrument uses these recorded signals to calculate values such as forced vital capacity and forced expiratory volume in one second. These outputs then provide the measurements needed to assess lung function and characterize respiratory patterns.
Researchers can use spirometry before and after an intervention to compare pulmonary function measurements and examine treatment responses. Changes in airflow or exhaled volume may indicate whether respiratory performance has altered during the study period. This application also complements longer-term monitoring, allowing treatment effects to be considered alongside broader changes in pulmonary health.
