Molecular hydrogen is a promising therapeutic agent for pulmonary disease » Molecular hydrogen exerts biological effects on nearly all organs. It has anti-oxidative, anti-inflammatory, and anti-aging effects and contributes to the regulation of autophagy and cell death. As the primary organ for gas exchange, the lungs are constantly… Ncbi.nlm.nih.gov

Pneumothorax » A pneumothorax is a collection of air outside the lung but within the pleural cavity. It occurs when air accumulates between the parietal and visceral pleurae inside the chest. The air accumulation can apply pressure on the lung and make it collapse. The degree of collapse determines the clinical presentation of pneumothorax. Air can enter the pleural space by two mechanisms, either by trauma causing communication through the chest wall or from the lung by rupture of the visceral pleura. There are two types of pneumothorax: traumatic and atraumatic. The two subtypes of atraumatic pneumothorax are primary and secondary. A primary spontaneous pneumothorax (PSP) occurs automatically without a known eliciting event, while a secondary spontaneous pneumothorax (SSP) occurs after an underlying pulmonary disease. A traumatic pneumothorax can be the result of blunt or penetrating trauma. Pneumothoraces can be even further classified as simple, tension, or open. A simple pneumothorax does not shift the mediastinal stru Ncbi.nlm.nih.gov

Hypoxic Brain Injury » The brain consumes a significant amount of energy compared to its weight and size. It is highly metabolically active and exquisitely sensitive to hypoxia and hypoperfusion. Cellular injury can begin within minutes, and permanent brain injury will follow if prompt intervention does not occur. Therefore, it is critical to understand the clinical presentation, pathophysiology, and management options. Ncbi.nlm.nih.gov
