ClinConnect Summary

This clinical trial is investigating how well lung ultrasound can help assess the condition of patients' lungs after heart surgery. The researchers want to see if changes in a specific lung ultrasound score are related to improvements in oxygen levels in the blood, which is measured using a ratio called PaO2/FiO2. By understanding this relationship, the goal is to determine if lung ultrasound can be a useful tool for physiotherapists as they treat patients who need breathing support after surgery.

To participate in this study, you need to be at least 18 years old, have undergone heart surgery with the use of a heart-lung machine, and be able to provide informed consent. You should also have a manageable level of pain and be alert and oriented. If you join the trial, you can expect to undergo lung ultrasound and receive physiotherapy combined with non-invasive ventilation, which helps support your breathing. This study is currently recruiting participants, and you can choose to withdraw at any time without affecting your care.
