Objectives

Narrative objectives1

Respiratory dynamics during ventilatory management (how each region of the lung moves depending on the state of breathing, whether alveoli are collapsed or overinflated, etc.) and safe ventilation settings are still unclear. We designed this study because 4D-CT (computed tomography with time axis) during ventilatory management is expected to improve patient prognosis by accurately assessing respiratory dynamics that have not been elucidated so far.

Basic objectives2

Others

Basic objectives -Others

By performing a CT scan with a time axis (4D-CT), it is now possible to evaluate the respiratory dynamics in detail, including what kind of ventilation is applied to each lung region and the risk of lung injury. This test is expected to improve the prognosis by enabling appropriate respiratory management to minimize ventilation induced lung injury. In addition, it is possible to analyze the ventilation mechanics in the state where ventilation by ventilator and spontaneous breathing are mixed, which has not been clearly elucidated so far, and it is expected to analyze the effects of asynchrony.

Proportion of ventilation dynamics by lung regions.

Key secondary outcomes

In this study, we will analyze the 4D-CT information in detail and validate the information obtained by this analysis according to several themes.
Evaluation of ventilation mechanics during asynchronies
Evaluation of optimal PEEP (positive end-expiratory pressure) and inspiratory pressure
Evaluation of optimal PEEP and inspiratory pressure
Incidence of ventilatory-related lung injury
Accuracy comparison with Electronic Impedance Tomography
The incidence of Pendelluft and evaluation of its dynamics and mechanism
Relevance of transpulmonary pressure information
Relationship between cardiac and pulmonary vascular circulatory dynamics and ventilation mechanics
Relevance of vascular permeability to ventilation mechanics
How the thorax and lungs move during ventilation
The relationship between vascular permeability and ventilation mechanics
Verification of respiratory dynamics before and after weaning from artificial respiration
The relationship between lung pathology and ventilation mechanics
Evaluation of the quality of spontaneous breathing and ventilation dynamics during forced ventilation

Other related information

In this study, 4D-CT will be performed at the time when chest CT is deemed necessary in the usual care. The patient will be moved to the CT room and managed with mechanical ventilation as in the usual care. Information such as EIT and esophageal pressure catheter will be collected before and after CT. All examinations and medical procedures, including 4D-CT, will be performed within the framework of usual care. The 4D-CT is already used in clinical practice in our hospital and is not invasive beyond the scope of usual care.
