Pulse Spectrum Analysis in Adult Asthmatics: Correlation With Lung Function, Asthma Control Exhaled Nitric Oxide and Metabolites in Exhaled Breath Condensate
An observational study of Pulse Spectrum Analysis and Pulmonary Function, run by National Taiwan University Hospital at 1 site in Taiwan.
Trial summary
Our hypothesis is that radial arterial pulse may reflect the severity and airway function in asthmatics. The aims of this study are to investigate the pulse spectrim of the radial artery in adult asthmatics, and evaluate its correlation with airy inflammation an lung funtion in asthmatics.

About this study
Official title: Pulse Spectrum Analysis in Adult Asthmatics: Correlation With Lung Function, Asthma Control Exhaled Nitric Oxide and Metabolites in Exhaled Breath
Our hypothesis is that radial arterial pulse may reflect the severity and airway function in asthmatics. The aims of this study are to investigate the pulse spectrim of the radial artery in adult asthmatics, and evaluate its correlation with airy inflammation an lung funtion in asthmatics.
Read the detailed description
The microcirculation is directly involved in the cellular matabolism and homeostasis. Our hypothesis is that radial arterial pulse spectrum may reflect the airway condition in asthmatics. The aims of this study are to investigate the pulse spectrim of the radial artery in adult asthmatics, and evaluate its correlation with lung function, asthma control status,exhaled nitric oxide, and metabolites in the exhaed breath condensates.

Questions about this trial
What is this clinical trial studying?
An observational study of Pulse Spectrum Analysis and Pulmonary Function, run by National Taiwan University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 1 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ping-Hung Kuo (886-2-23123456 ext. 63075, kph712@ntuh.gov.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pulse spectral analysis (time frame: one year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2012.
