What treatment tables are utilized with air?

The correct choice indicates that treatment tables 1A, 2A, and 3 are specifically designed for use with air. These tables are integral components of hyperbaric oxygen therapy protocols that help manage divers' emergency situations, including decompression sickness and arterial gas embolism.

Table 1A is typically used for specific situations involving simple decompression or minor nitrogen narcosis scenarios. Table 2A assists in managing more complex decompression issues, while Table 3 is geared towards advanced treatments that require special protocols for mixed gas diving. These tables allow for precise management of dive-related conditions by using air as the breathing gas.

Understanding the distinctions between air-based and other treatments is crucial. Other choices may reference tables that are suited for different scenarios, such as mixed gas diving or higher pressure settings, which would not be applicable when air is the primary breathing mixture. Therefore, for treatments focused specifically on air, the tables selected reflect the appropriate guidelines established for effective and safe management of diver health emergencies related to air.
