Elevation of spectral components of electrodermal activity precedes central nervous system oxygen toxicity symptoms in divers.

Journal Article Commun Med (Lond) · December 19, 2024 BACKGROUND: Oxygen-rich breathing mixtures up to 100% are used in some underwater diving operations for several reasons. Breathing elevated oxygen partial pressures (PO2) increases the risk of developing central nervous system oxygen toxicity (CNS-OT) whic ... Full text Link to item Cite

Does Heart Rate Variability Predict Impairment of Operational Performance in Divers?

Journal Article Sensors (Basel) · December 3, 2024 We examined data from Naval Sea Systems Command grant project N0463A-12-C-001, "Hypercapnia: cognitive effects and monitoring", with the objective of validating or repudiating heart rate variability (HRV) as a warning sign of cognitive impairment from divi ...

Prediction of central nervous system oxygen toxicity symptoms using electrodermal activity and machine learning

Journal Article Biocybernetics and Biomedical Engineering · April 1, 2024 Objective: Breathing elevated oxygen partial pressures (PO2) prior to SCUBA diving increases the risk of developing central nervous system oxygen toxicity (CNS-OT), which could impair performance or result in seizure and subsequent drowning. We aimed to st ... Full text Cite

Effects of submersion on VO2: comparing maximum aerobic exertion on land and underwater.

Journal Article Undersea Hyperb Med · 2024 INTRODUCTION: Submersion results in blood redistribution into the pulmonary circulation, causing changes in pulmonary compliance and increased cardiac preload. Few studies have compared incremental exercise to exhaustion (VO2 max testing) in a dry environm ... Link to item Cite

Time-varying Spectral Index of Electrodermal Activity to Predict Central Nervous System Oxygen Toxicity Symptoms in Divers: Preliminary results.

Journal Article Annu Int Conf IEEE Eng Med Biol Soc · November 2021 The most effective method to mitigate decompression sickness in divers is hyperbaric oxygen (HBO2) pre-breathing. However, divers breathing HBO2 are at risk for developing central nervous system oxygen toxicity (CNS-OT), which can manifest as symptoms that ... Full text Link to item Cite

Portable Neuromonitoring Device Detects Large Vessel Occlusion in Suspected Acute Ischemic Stroke.

Journal Article Stroke · April 2021 BACKGROUND AND PURPOSE: Early detection of large vessel occlusion (LVO) stroke optimizes endovascular therapy and improves outcomes. Clinical stroke severity scales used for LVO identification have variable accuracy. We investigated a portable LVO-detectio ... Full text Link to item Cite

Successful treatment of pneumatosis intestinalis with associated pneumoperitoneum and ileus with hyperbaric oxygen therapy.

Journal Article BMJ Case Rep · May 30, 2017 Pneumatosis intestinalis (PI), or the presence of air in the bowel wall, is a rare disorder that is associated with a variety of underlying diseases, including connective tissue disorders. PI presents on a spectrum from asymptomatic to bowel obstruction an ... Full text Open Access Link to item Cite

Assessment of the interaction of hyperbaric N2, CO2, and O2 on psychomotor performance in divers.

Journal Article J Appl Physiol (1985) · October 1, 2016 Diving narcosis results from the complex interaction of gases, activities, and environmental conditions. We hypothesized that these interactions could be separated into their component parts. Where previous studies have tested single cognitive tasks sequen ... Full text Link to item Cite

Cerebral Arterial Gas Embolism During Upper Endoscopy.

Journal Article A A Case Rep · September 15, 2015 Arterial gas embolism can be caused by direct entry of gas into systemic arteries or indirectly by venous-to-arterial shunting. Although arterial gas embolism is rare, most documented cases are iatrogenic, resulting from the entry of gas during procedures ... Full text Link to item Cite

Survey of patient and physician influences and decision-making regarding CT utilization for minor head injury.

Journal Article Injury · September 2014 OBJECTIVE: Assess factors that influence both the patient and the physician in the setting of minor head injury in adults and the decision-making process around CT utilization. METHODS: This is a convenience sample survey study of adult minor head injury p ... Full text Link to item Cite
