The effect of a single closed‐circuit rebreather decompression dive in extremely cold water to cardiac function
Laura J. Tuominen, Suvi Tuohinen, Richard V. Lundell, Anne K. Räisänen‑Sokolowski, Tomi Wuorimaa

Purpose: Dive-induced cardiac and hemodynamic changes are caused by various mechanisms, and they are aggravated by cold water. Therefore, aging divers with pre-existing cardiovascular conditions may be at risk of acute myocardial infarction, heart failure, or arrhythmias while diving. The aim of this study was to assess the effect of a single decompression CCR dive in arctic cold water on cardiac function in Finnish technical divers.

Oxygen Variations—Insights into Hypoxia, Hyperoxia and Hyperbaric Hyperoxia—Is the Dose the Clue?
Balestra C, Mrakic-Sposta S, Virgili F.

Molecular oxygen (O2) is one of the four most important elements on Earth (alongside carbon, nitrogen and hydrogen); aerobic organisms depend on it to release energy from carbon-based molecules.

Relative Hypoxemia at Depth During Breath-Hold Diving Investigated Through Arterial Blood Gas Analysis and Lung Ultrasound.
Paganini M, Moon RE, Giacon TA, Cialoni D, Martani L, Zucchi L, Garetto G, Talamonti E, Camporesi EM, Bosco G.

Pulmonary gas exchange in breath-hold diving (BHD) consists of a progressive increase in arterial PO2 and PCO2 (PaO2 and PaCO2) during descent. However, recent findings have demonstrated that PaO2 does not consistently rise in all subjects. This study aimed at verifying and explaining PaO2 derangements during BHD analyzing arterial blood gases and searching for pulmonary alterations with lung ultrasound.

Does Decreased Diffusing Capacity of the Lungs for Carbon Monoxide Constitute a Risk of Decompression Sickness in Occupational Divers?
Loddé B, Giroux-Metges MA, Galinat H, Kerspern H, Pougnet R, Saliou P, Guerrero F, Lafère P.

Long-term alterations of pulmonary function (mainly decreased airway conductance and capacity of the lungs to diffuse carbon monoxide (DLCO)) have been described after hyperbaric exposures. However, whether these alterations convey a higher risk for divers' safety has never been investigated before.
