NCT ID: NCT05430503 Completed - Long COVID Clinical Trials

Long COVID and Post-exertional Pulmonary Diffusion

Long_COVID_Ex
Start date: May 24, 2022
Phase:
Study type: Observational [Patient Registry]

Aim of investigators was to study whether abnormalities of lung diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO) in long COVID may have a clinical impact in relation to exercise intolerance.

NCT ID: NCT01686984 Completed - Carbon Dioxide Clinical Trials

Influence of Inspiratory Flow Pattern on Exchange of Carbon Dioxide in Humans Without Primary Lung Disease

Start date: September 2012
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate how inspiratory flow pattern influences CO2 elimination in people without primary lung disease. The hypothesis is that a long mean distribution time, caused by a long postinspiratory pause and high end-inspiratory flow, will promote CO2 exchange in the alveoli.
