Which of the following lifeguard skills are typically performed similarly in open water as in non-open water facilities?

Using a resuscitation mask and AED is a skill that remains consistent in both open water and non-open water environments. The fundamental aspects of performing rescue breathing and using an automated external defibrillator (AED) do not change based on the setting. Lifeguards are trained to deliver these lifesaving techniques effectively regardless of where the emergency occurs.

In open water, conditions may differ, such as the presence of waves or currents, but the use of the resuscitation mask and AED follows the same procedures designed for maximizing the chances of survival after a cardiac arrest. It is crucial for lifeguards to be proficient in these skills, as they are vital components of emergency response, thereby ensuring that lifesaving measures are standardized across different environments.

In contrast, certain other skills like performing CPR on land may vary in technique due to environmental factors, while setting up safety barriers might not be relevant in open water settings as they are in pools. Checking guest wristbands is typically a practice found in controlled environments like pools or water parks and does not apply in the vastness of open water scenarios.
