Key Points

To assess the presence of pendelluft in a patient with flail chest using electrical impedance tomography (EIT).
Evaluated chest wall motion and ventilation dynamics using EIT.
Managed flail chest with mechanical ventilation and internal fixation.
Monitored for paradoxical movement resolution and stability of chest segments.
Pendelluft persisted despite stabilization of paradoxical motion.
EIT demonstrated unstable chest wall segments leading to ventilation discrepancies.
Emphasis on achieving homogenized ventilation dynamics for better outcomes.

Abstract

ABSTRACT An 80‐year‐old man with flail chest exhibiting paradoxical chest wall movement required mechanical ventilation for internal fixation. Despite the apparent paradoxical motion resolution, unstable chest wall segments allowed pendelluft to persist. Thus, EIT‐guided management of flail chest should focus on stabilising the visible chest wall and achieving homogenised ventilation dynamics.
