Lung Ultrasound for Mechanical Ventilation Complication
(Strain Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to enhance the safety of mechanical ventilation by using lung ultrasound to detect potential lung injuries early. It focuses on understanding normal lung stretch in healthy individuals, which could help prevent issues in those with lung diseases. The trial employs ultrasound, a safe and non-invasive tool, to measure lung strain (stretch) in different lung areas. Healthy individuals who have never smoked and have no lung diseases may be suitable candidates for this trial. As an unphased study, this trial offers a unique opportunity to contribute to advancing medical knowledge and improving future patient care.
Will I have to stop taking my current medications?
The trial information does not specify whether you need to stop taking your current medications. However, since the study involves healthy volunteers without pre-existing pulmonary conditions, it's possible that certain medications might be restricted. Please consult with the trial coordinators for specific guidance.
What prior data suggests that lung ultrasound is safe for assessing pleural strain?
Research shows that lung ultrasound is safe in medical settings. Studies have found it to be a non-invasive and radiation-free method, making it easy for patients to tolerate. No reports of serious side effects have emerged from using lung ultrasound, and it is already commonly used in intensive care units. It aids doctors in making better decisions about patient care, especially for those on breathing machines. Although lung ultrasound is not new, its ability to detect lung problems early is promising. This could lead to safer treatment changes for patients needing breathing support.12345
Why are researchers excited about this trial?
Researchers are excited about using lung ultrasound for mechanical ventilation complications because it offers a non-invasive way to assess lung health. Unlike traditional methods that might involve more invasive procedures or radiation exposure, this approach uses ultrasound technology to visualize and evaluate the lungs safely. By calculating the Von Mises coefficient with a vascular elastography platform, this technique provides detailed insights into pleural strain, helping doctors make more informed decisions. This method could potentially lead to quicker, more accurate detection of complications, improving patient outcomes without the risks associated with current diagnostic techniques.
What evidence suggests that lung ultrasound is effective for detecting pulmonary overdistension?
Research has shown that lung ultrasound, the focus of this trial, serves as a helpful tool for managing patients on breathing machines. Studies indicate it can detect lung problems early, potentially preventing further damage. This non-invasive method is used in critical care to assess lung conditions without exposing patients to radiation. It effectively identifies lung issues. By providing real-time images, lung ultrasound aids doctors in making safer decisions about machine settings, potentially reducing complications such as ventilator-induced lung injury.13456

Are You a Good Fit for This Trial?
This trial is for healthy volunteers aged 18 and over, with a good level of fitness (able to perform activities worth more than 4 METs). It's not suitable for those who've had chest surgeries, are obese (BMI over 30), have lung diseases like asthma or COPD, or are current/former smokers.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Measurement
Participants will have their functional residual capacity (FRC) measured by a nitrogen dilution technique and will breathe 8 different inspired volumes. Tidal volumes will be measured using a spirometer.
Ultrasonography
Ultrasonographic imaging will be used to calculate pleural strain values at 15 predetermined lung areas using a non-invasive vascular elastography platform.
Follow-up
Participants are monitored for any immediate adverse effects after the ultrasonography procedure.
What Are the Treatments Tested in This Trial?
Interventions
- Lung ultrasound
Trial Overview
The study is testing the use of lung ultrasound as a tool to measure pulmonary strain in healthy individuals. The goal is to establish normal values for lung strain during mechanical ventilation and understand how it relates to different volumes of air inspired into the lungs.
