Deep Learning-Based Venous Gas Emboli Grade Classification in Doppler Ultrasound Audio Recordings.

Journal Article IEEE Trans Biomed Eng · May 2023 OBJECTIVE: Doppler ultrasound (DU) is used to detect venous gas emboli (VGE) post dive as a marker of decompression stress for diving physiology research as well as new decompression procedure validation to minimize decompression sickness risk. In this art ... Full text Link to item Cite

An open-source framework for synthetic post-dive Doppler ultrasound audio generation.

Journal Article PLoS One · 2023 Doppler ultrasound (DU) measurements are used to detect and evaluate venous gas emboli (VGE) formed after decompression. Automated methodologies for assessing VGE presence using signal processing have been developed on varying real-world datasets of limite ... Full text Link to item Cite

Development of a graphical user interface for automatic separation of human voice from Doppler ultrasound audio in diving experiments.

Journal Article PloS one · January 2023 Doppler ultrasound (DU) is used in decompression research to detect venous gas emboli in the precordium or subclavian vein, as a marker of decompression stress. This is of relevance to scuba divers, compressed air workers and astronauts to prevent decompre ... Full text Cite

The Dewey Monitor: Pulse Oximetry can Warn of Hypoxia in an Immersed Rebreather Diver in Multiple Scenarios.

Journal Article Annals of biomedical engineering · February 2022 Divers who wish to prolong their time underwater while carrying less equipment often use devices called rebreathers, which recycle the gas expired after each breath instead of discarding it as bubbles. However, rebreathers' need to replace oxygen used by b ... Full text Cite

Testing of full face snorkel masks to examine recreational snorkeler deaths.

Journal Article Undersea & hyperbaric medicine : journal of the Undersea and Hyperbaric Medical Society, Inc · January 2022 A recent rise in snorkeling-related deaths in Hawaii has inspired several bans on full face snorkel masks (FFSMs). However, while there are theories to explain the deaths, little physiological data exists about the way the FFSMs provide gas to an exercisin ... Cite

Did a "lucky shot" sink the submarine H.L. Hunley?

Journal Article Forensic Sci Int · January 2017 The H.L. Hunley was the first submarine to be successful in combat, sinking the Union vessel Housatonic outside Charleston Harbor in 1864 during the Civil War. However, despite marking a milestone in military history, little is known about this vessel or w ... Full text Link to item Cite

Air blast injuries killed the crew of the submarine H.L. Hunley.

Journal Article PLoS One · 2017 The submarine H.L. Hunley was the first submarine to sink an enemy ship during combat; however, the cause of its sinking has been a mystery for over 150 years. The Hunley set off a 61.2 kg (135 lb) black powder torpedo at a distance less than 5 m (16 ft) o ... Full text Open Access Link to item Cite

The Dewey monitor: Pulse oximetry can independently detect hypoxia in a rebreather diver.

Journal Article Undersea Hyperb Med · 2017 Rebreather diving has one of the highest fatality rates per man hour of any diving activity in the world. The leading cause of death is hypoxia, typically from equipment or procedural failures. Hypoxia causes very few symptoms prior to causing loss of cons ... Full text Open Access Link to item Cite

Behind armor blunt trauma: Recreation of field cases for the assessment of backface signature testing

Conference Proceedings - 30th International Symposium on Ballistics, BALLISTICS 2017 · January 1, 2017 A total of 47 real-world cases were re-created in a laboratory environment. Cases were identified from the IACP/DupontĀ® and Safariland survivors' databases. Exemplar armor was obtained for testing in the laboratory. Details surrounding the incident were de ...

Did the crew of the submarine H.L. Hunley suffocate?

Journal Article Forensic Sci Int · March 2016 On the evening of February 17th, 1864, the Confederate submarine H.L. Hunley attacked the Union ship USS Housatonic outside Charleston, South Carolina and became the first submarine in history to successfully sink an enemy ship in combat. One hypothesis fo ...

Underwater blast injury: a review of standards.

Journal Article Diving Hyperb Med · September 2015 The first cases of underwater blast injury appeared in the scientific literature in 1917, and thousands of service members and civilians were injured or killed by underwater blast during WWII. The prevalence of underwater blast injuries and occupational bl ... Link to item Cite

Human Injury Criteria for Underwater Blasts.

Journal Article PLoS One · 2015 Underwater blasts propagate further and injure more readily than equivalent air blasts. Development of effective personal protection and countermeasures, however, requires knowledge of the currently unknown human tolerance to underwater blast. Current guid ... Full text Link to item Cite
