Hyperbaric oxygen therapy in the ATLS/ACLS resuscitative management of acutely ill or severely injured patients with severe anemia: a review.

For short periods, even without the presence of red blood cells, hyperbaric oxygen can safely allow plasma to meet the oxygen delivery requirements of a human at rest. By this means, hyperbaric oxygen, in special instances, may be used as a bridge to lessen blood transfusion requirements. Hyperbaric oxygen, applied intermittently, can readily avert oxygen toxicity while meeting the body's oxygen requirements.

Decadal changes in microplastic accumulation in freshwater sediments: Evaluating influencing factors.

Microplastics are small plastic particles with sizes ranging between 1 μm and 5 mm. Microplastics can originate from macro plastics and degrade to a smaller size or be produced directly by manufacturers. Few studies have examined microplastic contamination in freshwater sediment cores to estimate changes in microplastic contamination over time.

Medical and surgical management of pneumothorax in diving and hyperbaric chambers.

The presence of a pneumothorax within a pressurized chamber represents unique diagnostic and management challenges. This is particularly the case in the medical and geographic remoteness of many chamber locations. Upon commencing chamber decompression, unvented intrapleural air expands.

Assessment of Functional and Physical Performances of Pre-filled Syringes in Deep Cold Storage Conditions.

The recent emergence of new drug technologies such as messenger ribonucleic acid-based vaccines developed to fight the outbreak of the COVID-19 global pandemic has driven increased demand for delivery solutions capable of withstanding deep cold storage conditions down to -50°C, and even down to -80°C. Although significant data exist for deep cold storage in vials, little evidence is available for pre-filled syringes. Because pre-filled syringes serve as both the storage container and the delivery mechanism, there are additional risks to performance that must be evaluated, such as plunger gliding performance, syringe lubrication, silicone layer stability, and container closure integrity (CCI).
