Daniel stumbled over to the DHD and Jack took advantage, sinking to his knees. The minute or so it would take the Gate to dial was an excellent opportunity for him to put his head down and concentrate on nothing more than desperately sucking in air. His chest burned; his heart raced; his fingers felt numb. If they didn't get through the Gate soon, he wouldn't be able to do so under his own steam. "Teal'c," he managed.

"I am fine."

"Carter?"

"She is breathing."

So maybe they'd made it in time. Out of the corner of his eye, Jack saw Daniel wilt to the ground beside the DHD.

The kawoosh was so bright. And his head hurt so much.

Easily shifting Sam's body in his massive arms, Teal'c entered SG-1's GDO code along with a request for medical assistance and received confirmation almost immediately. "The iris is open, O'Neill."

"Okay," Jack panted. "Daniel."

"I just need one more minute," the younger man gasped.

"No. No, now." Forcing himself to his feet, Jack stumbled over to his friend and yanked at the shoulder of his uniform. "Daniel."

He was equally unsteady on his feet, but it kinda balanced out. Leaning on each other, they staggered toward the Gate together with Teal'c and Carter right behind.

Jack and Daniel sank to the metal grating at the top of the ramp, unable to go a step further. "What happened?" Doctor Fraiser asked as Teal'c navigated between them, then walked down the ramp to carefully place Major Carter, unconscious, on one of the waiting stretchers.

"They are having difficulty breathing," the Jaffa told her. "Major Carter was affected first, then the others. I believe they are in need of oxygen."

"Check them," the doctor ordered, pointing toward the ramp with her left hand as her right drew a small device from a pocket and clipped it to her patient's index finger. It didn't take long to read. "Eight-four percent," she announced to her team. "Let's get a mask on her."

"Eighty-nine," the nurse beside Jack called back. Daniel's was ninety.

"What is the appropriate number?" Teal'c asked.

"High nineties," Janet told him. "Ninety-five isn't great. Ninety will get you hospitalized. I need your hand."

"I am fine."

Her tone made it clear it wasn't really optional. "Teal'c, give me your hand." When he acquiesced, she put the same device on his finger that she'd used on Major Carter and frowned. "Eight-nine," she told him. "You are not fine. Let's get them to the infirmary," she ordered her team. "O2 all around."
