A Sebastes-specific complementary DNA (cDNA) microarray was developed to identify potential biomarkers involved in the capture stress and recovery of Sebastes species if they are assisted in returning to their original depth of capture following barotrauma. Black rockfish Sebastes melanops were exposed to simulated decompression from 450 kPa (c. 35 m depth) (which resulted in barotrauma) and su...

Barotrauma from arc induced shock waves may result in dangerous sequelae during ablation of arrhythmogenic foci. In this report, maximum pulse amplitude and pulse width determinations were made to assess avoidance of shock-wave generation using rectangular constant current pulses. Energy delivery appears to be optimal between 80-100 microseconds. If higher energies are required, multiple pulses...

Techniques were developed to determine which life stages of fish are vulnerable to barotrauma from expansion of internal gases during decompression. Eggs, larvae, and juvenile hatchery-reared white sturgeon (Acipenser transmontanus; up to 91 days post hatch; d.p.h.) were decompressed to assess vulnerability to barotrauma and identify initial swim bladder inflation. Barotrauma-related injury and...

A compressed air diver suffered pulmonary barotrauma with arterial air embolization; resuscitation was unsuccessful. Attempts at resuscitation included mouth-to-mouth ventilation and cardiac massage. A chest radiograph taken during resuscitation revealed free intraperitoneal air. Postmortem examination showed rupture of the stomach. The two possible aetiological factors--barotrauma of ascent an...

We present the case of a 24-year-old male who presented to the otolaryngology clinic for otalgia and aural fullness after riding a roller coaster. We present his clinical course and outcome and briefly discuss the mechanism of injury and otologic barotrauma. Roller coasters have been reported as the cause of many different types of injuries, but this is the first reported case of otologic barot...

OBJECTIVE To catalog the side effects of 2.4 atmospheres absolute (atm abs) hyperbaric oxygen (HBO2) vs. sham on post-concussion symptoms in military service members with combat-related, mild traumatic brain injury (TBI). METHODS Fifty subjects diagnosed with TBI were randomized to either a sham (1.3 atm abs breathing air) or treatment (2.4 atm abs breathing 100% oxygen) hyperbaric profile. F...

Objective.: To report the high incidence of barotrauma in critically ill patients admitted to intensive care unit (ICU) with coronavirus disease 2019 (COVID-19) and discuss its implications. Design.: Retrospective cohort study. Setting.: ICU an academic county hospital Los Angeles, CA from March 15-June 20, 2020. Patients.: 77 COVID-19 pneumonia. 75 met inclusion criteria. Results.: 21% severe ...
