Examining lung ultrasound and oxygen levels after heart surgery
Study of the Relationship Between the Relative Variation of PaO2/FiO2 and the Variation of Lung Ultrasound Score During the First Session of Physiotherapy Associated With Non-invasive Ventilation in Cardiac Surgery Patients by Cardiopulmonary Bypass
This study is testing if lung ultrasound results can help doctors understand how well patients are breathing after heart surgery.

What this trial studies
This study investigates the relationship between lung ultrasound scores and the oxygenation state of patients following cardiac surgery. It aims to determine if changes in the PaO2/FiO2 ratio correlate with lung ultrasound scores, providing a non-invasive method to assess respiratory function. The study involves patients who have undergone heart surgery and are receiving physiotherapy and non-invasive ventilation. By establishing this relationship, the study seeks to enhance the evaluation tools available to physiotherapists in managing post-surgical respiratory complications.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18 and older who have undergone heart surgery and are prescribed non-invasive ventilation and physiotherapy.
Not a fit: Patients who experience cardiorespiratory arrest or require reintubation during the inclusion visit will not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved monitoring and management of respiratory function in patients after heart surgery.
How similar studies have performed: While lung ultrasound is gaining traction in clinical settings, this specific correlation between lung ultrasound scores and oxygenation post-heart surgery is novel and has not been extensively studied.
