ClinConnect Summary

This clinical trial is studying how lung ultrasound and a special type of blood flow measurement called pulsed-wave Doppler can help doctors better understand lung problems in patients who are on mechanical ventilation. Specifically, the trial looks at two conditions: atelectasis (when part of the lung collapses) and pneumonia (an infection in the lungs). The researchers want to see how the blood flow in the lungs changes in these conditions, which could help in managing the patients' care.

To participate in this trial, patients must be between the ages of 65 and 74 and currently receiving mechanical ventilation with visible lung consolidations on imaging tests like chest X-rays or CT scans. However, there are some exclusions, such as those who have been in other studies recently or have certain health issues that make participation unsafe. If eligible, participants can expect to undergo non-invasive lung ultrasound and blood flow measurements as part of their routine care. This study aims to improve how doctors assess and treat lung issues in critically ill patients, which could lead to better outcomes.
