How long does one surD O2 period last?

The correct duration of a surD O2 period is indeed 30 minutes. This period is crucial in underwater rescue scenarios as it directly relates to the time responders have available to safely administer oxygen to individuals experiencing hypoxia or other oxygen-related issues after emerging from pressure.

Understanding the significance of this duration is important because it helps responders plan their actions effectively, ensuring they provide the necessary care within the established guidelines. The 30-minute time frame allows enough time for monitoring the oxygen intake and response of the individual, improving their chances of recovery. Properly adhering to this duration enhances the overall effectiveness of the rescue operation.
