Gas embolism is a procedure-related complication and has been reported during endoscopy, surgical procedures, intravenous catheterization, positive pressure ventilation, and a multitude of scenarios. Recognizing the potential for gas embolus and a high level of suspicion are paramount to timely intervention to prevent significant morbidity and mortality. There is such rapid decompensation that only clinical suspicion can guide timely intervention; it is not uncommon for gas embolus to be diagnosed postmortem. It then must be determined whether the gas embolus has a venous or systemic entry point. Overall management is similar for both forms of gas emboli with focus on hemodynamic support and preservation of organ function. This case report discusses an occurrence of presumed systemic gas embolus from argon plasma coagulation and management of a patient under general anesthesia during rigid bronchoscopy.

A common assumption of plant hydraulic physiology is that high hydraulic efficiency must come at the cost of hydraulic safety, generating a trade-off that raises doubts about the possibility of selecting both productive and drought-tolerant herbaceous crops. Wetland plants typically display high productivity, which requires high hydraulic efficiency to sustain transpiration rates coupled to CO uptake. Previous studies have suggested high vulnerability to xylem embolism of different wetland plants, in line with expected trade-offs.

Introduction: Ischaemic stroke, primarily caused by thromboembolic events, typically arises as a consequence of underlying vascular or cardiac pathology. Non-thrombotic embolic strokes, although rare, are increasingly seen in interventional and intravascular procedures. Oxygen-ozone therapy (OOT) is one of the popular treatments for lumbar disc herniation, providing pain relief.

Up to 50% of patients with pulmonary embolism (PE) experience hemodynamic instability and approximately 70% of patients who die of PE experience an accelerated cascade of symptoms within the first hours of onset of symptoms, thus necessitating rapid evaluation and intervention. Venoarterial extracorporeal membrane oxygenation and other ventricular assist devices, depending on the hemodynamic derangements present, may be used to stabilize patients with massive PE refractory to initial therapies or with contraindications to other interventions. Given the abnormalities in both pulmonary circulation and gas exchange caused by massive PE, venoarterial extracorporeal membrane oxygenation may be considered the preferred form of mechanical circulatory support for most patients.

Background: Arterial gas embolism (AGE) may occur while breathing compressed air and failing to exhale during ascent to compensate for gas expansion as pressure decreases. Trauma to the lungs from over-pressurization may result in air bubbles entering the pulmonary veins and subsequently the systemic circulation, causing obstructed blood flow and inflammatory cascades. AGEs are known to always manifest within 10 min of surfacing from depth.

Subcutaneous emphysema is the accumulation of gas or air in loose subcutaneous connective tissue. The use of air-driven handpieces in dental procedures is a common iatrogenic cause of intraoral mucogingival barrier disruption by high-pressure air. This case report describes a 60-year-old woman who underwent prophylactic periodontal treatment with an air-abrasive device and subsequently developed severe bilateral subcutaneous emphysema, extending from the temporal region to the thoracic and mediastinal spaces.
