Asthma, COPD

The goal of this physiological pilot study with a randomized crossover design is to study the effect of Flow-controlled ventilation (FCV) on the minute volume compared to Volume-controlled ventilation (VCV) in intubated patients with an exacerbation of their asthma or COPD. Our hypothesis is that FCV will results in a lower minute volume compared to VCV in this patient category. Patients will be randomized between two ventilation sequences, namely 90 minutes of FCV followed by 90 minutes of VCV or vice versa.

This study evaluates whether adding a spacer device to triple inhaled therapy (ICS/LABA/LAMA via pMDI) can reduce acute exacerbations in elderly patients (≥65 years) with stable chronic airway diseases (COPD or asthma) who are classified as high-risk based on GOLD or GINA guidelines. High risk is defined as ≥1 hospitalization or ≥2 moderate exacerbations in the past 12 months. Despite receiving triple inhaled therapy, these patients often have poor inhaler technique due to age-related limitations. A spacer may improve drug delivery, adherence, and reduce local side effects. In this multicenter, open-label, randomized controlled trial, 380 participants will be assigned to standard therapy with or without a valved spacer. The primary outcome is the 3-month incidence of moderate-to-severe exacerbations. Secondary outcomes include lung function, adherence, inhalation technique, side effects, and patient satisfaction.

Unicentric retrospective study designed to analyses the performance of various machine learning approaches to predict patterns of chronic respiratory diseases such as asthma, based mainly on clinical information and respiratory spirometry/oscillometry.

Dynamic digital radiography (DDR) is a new advanced version of chest radiography that captures dynamic images at a rate of 15 frames per second. It is coupled with an analytical software that allows it to provide more advanced measures of lung motion, ventilation, and perfusion compared to traditional chest radiography. While implementation of DDR fixed machines are beginning elsewhere in the US, this trial involves the first applications of an FDA-approved portable DDR machine, for use at the bedside in the ICU. The goal of this clinical trial is to determine the feasibility and safety of portable DDR technology in the ICU, as well as to evaluate the improved clinical diagnostic value of the portable DDR system over current standards of care. Participants will receive one to three sets of DDR images, which will then be compared to their clinical gold standard exams (such as chest x-rays, CTs, or VQ scans) to assess and improve the precision and accuracy of measurements such as diaphragmatic motion, lung movement, and perfusion.
