The attendant was concerned, and rightfully so. Clearly, they had been in the water too long and gotten quite overheated.

He helped move them to a cooler, air-conditioned room, but left them without clothes. He'd put a few ice packs around Madara's neck and gave Sasuke a basin of cool water that he could sponge on. It wasn't long before he started to stir.

Itachi, though, was still out cold. His breathing was very shallow, his pulse was fast and his color was definitely off. The fact that there was an oxygen tank with his clothes was a godsend, and the attendant went for it immediately, along with ice packs for all the vital, blood-rich areas. Of course, he did all of this after sending a fellow attendant to fetch a medic from the clinic across the street. You can never be too careful!
