An alarm woke her up in the middle of the night.
She rubbed her eyes, but knew that wishing it away wouldn't work.
"Jarvis?" she asked.
"Sorry to wake you, but Mr Stark is in need of your assistance."
"What'saproblem?" Ron muttered, his head popping up from the pillow to ask.
"Tony fucking Stark," she swore, and Ron took that as enough explanation, his head falling back to the pillow.
"Where is he Jarvis?" she asked, pulling a jumper on top of her pyjamas.
"Mr Stark is currently in the kitchen on his floor."
She stumbled out the door of their quarters and over to the lift, where it was already waiting for her.
"What is it? Because if it's another 'hold this thing while I fix this so it doesn't explode' I will hurt him."
"No at all," Jarvis said quickly. "He appears to be unwell, and is not responsive."
"Right. Is anyone else up?"
"Thor is awake."
"Great. Can you have him bring a stretcher to Tony? Actually, no, just have him meet me in the kitchen, he can just carry Tony."
"Of course. Anything else?"
"Do you have vitals?" she asked as the doors opened on Tony's floor. Pepper was in Japan or China on business, one of the entire day by aeroplane countries.
"Temperature is elevated, as is pulse and respiration. Left here," he instructed.
"Thank you," she muttered, spotting Tony slumped on the floor. "Did he fall?" she ordered, kneeling next to him. "Lights on please."
The kitchen lit up as Jarvis began to speak. "He fell from standing, and did not hit his head on the way down. Spinal precautions are not necessary."
"Love you Jarvis."
"Thor is on his way, " he said in response, which she knew meant 'love you too' in Jarvis speak.
She rolled Tony from his fetal position on to his back. He stirred slightly, but didn't awaken. She only had time to get a pulse and respiratory rate before Thor appeared.
"Healing maiden, how is friend Stark?"
"Not well Thor," she replied. "I need you to carry him to the medical floor for me."
Thor bent over and scooped Tony gently into his arms, cradling his head like one would with an infant. Miranda nearly had to run to keep up with his hurried footsteps.
"He is warm," Thor noted while they were in the lift.
"Yeah," she conceded, distracted by the rasp in Tony's chest. "He's probably got an infection of some sort, in his lungs by now, because he's lucky like that."
The doors of the lift opened, and Thor strode over to a bed, setting Tony down with care.
"Do you require further assistance? Shall I fetch Dr Banner?"
"Oh, no thank you Thor. Jarvis will be able to alert you or anyone else if we need you. Thank you for carrying Tony."
He bowed slightly to her, and left.
She set to work, stripping Tony's shirt off to place EKG leads. She placed a probe on his finger, and frowned when it announced what the oxygen saturation in his blood was.
"I know that your sats are normally lower, but that's still too low. Jarvis, what are his baselines?" she asked, untangling the tubing of an oxygen mask.
"92 to 95 percent," Jarvis replied.
She glanced back up at the screen. 88. "You're a mess Tony," she sighed, placing the mask on his face and turning up the flow of oxygen.
"Dehydrated too, of course," she noted. At least his temperature was low grade, not high enough to be risking brain damage or seizures. Because that was all he needed.
She set about finding a vein while watching his sats rise.
"Your veins are rubbish," she told him. Miranda stepped back and considered her options. There was a potentially viable vein on his left hand, and that was about it. She could always throw in a central line, or an intraosseous line, but she'd rather not.
"Sorry about this," she said in advance, before attempting to cannulate his hand.
"Oh, I think it worked," she said, drawing back blood. Of course, as soon as she said that, the vein collapsed and she had nothing to work with. "Dammit," she muttered. "I suppose it's settled then. Subclavian would probably be best," she told herself, feeling along Tony's neck and collarbone.
She stuck a plaster on his hand, and set up to insert a line into the larger vein.
