What should be obtained as part of the corrective actions for DCS?

Obtaining medical assistance is crucial as part of the corrective actions for Decompression Sickness (DCS). DCS occurs when a diver ascends too quickly, causing nitrogen bubbles to form in the bloodstream and tissues due to rapid reduction in pressure. The condition can lead to serious medical complications that may require immediate intervention.

Medical professionals trained in diving medicine can administer treatments such as hyperbaric oxygen therapy, which is the primary method for effectively treating DCS. This therapy helps to reduce the size of nitrogen bubbles in the body, increases the amount of oxygen in the bloodstream, and promotes the healing of affected tissues.

While other options may relate to potential scenarios in aviation or diving, they do not directly address the immediate medical needs posed by DCS. For instance, diving equipment is pertinent to the activity but does not provide the necessary medical intervention, and in-flight refueling or oxygen masks do not serve the purpose of treating DCS. Thus, the focus on medical assistance is the most appropriate corrective action for addressing the condition.
