A SCUBA diving emergency

  • Comment

This SCUBA diver surfaced with memory loss and became unresponsive.

He did not ascend rapidly, and these red marks on his neck became apparent shortly after. Which condition is the most likely cause of his cognitive dysfunction?

Answer: These neurologic deficits point towards Type II decompression sickness, believed to be the result of venous obstruction. Venous obstruction is caused by the coalescence of gas bubbles within the low pressure venous drainage system in the brain. Treatment for decompression syndrome includes hydration, administration of 100% oxygen, and left lateral decubitus placement of the patient.
