Abstract:
Emergent indications for HBO2 are not only for some of the most serious conditions, but also may be the only modality to directly target the patient's pathophysiology. They are to begin emergently or urgently, but may be limited by either the instability of the patient's condition or transfer logistics. Often these emergent treatments involve several treatments in the first 24 hours for best outcomes. If one considers the effects of HBO2 upon the body while breathing 100% oxygen at pressure many benefits become evident. This article will concisely review hyperbaric oxygen's emergent indications.

Guidelines in Case of a Laboratory Emergency
The most common laboratory emergencies include chemical spills, fire or explosion, electric shock, and personnel injuries. Most laboratory accidents occur due to poor planning or lack of attention. Therefore, it's always better to prevent accidents (being proactive) than having to take any actions during an emergency (being reactive). For example, always wear proper personal protective equipment (PPE) in the...
