Point-of-care ultrasound in a multiplace hyperbaric chamber

Historically, electronic devices have been generally prohibited during hyperbaric oxygen (HBO₂) therapy due to risk of fire in a pressurized, oxygen-rich environment. Point-of-care ultrasound (POCUS), however, has emerged as a useful imaging modality in diverse clinical settings. Hyperbaric chambers treating critically ill patients would benefit from the application of POCUS at pressure to make real-time patient assessments. Thus far, POCUS during HBO₂ therapy has been limited due to required equipment modifications to meet safety standards. Here we demonstrate proof of concept, safety, and successful performance of an off-the-shelf handheld POCUS system (SonoSite iViz) in a clinical hyperbaric environment without need for modification.
