Two days ago Jill was fitted with full military flying gear. She spent the rest of that day and the next practicing the proper suiting-up. Jill wore her cotton bra and panties under a tailored nomex jumpsuit. Next she pulled on her anti-g suit, zipping tight to her legs and clenching her stomach firmly. She was well girdled, a little restricted in her breathing. Jill then donned her helmet, an HGU-55 fitted to her with the standard sizing pads. From her helmet dangled an oxygen mask, a modified MBU-12p, gray hose and gray face piece. The mask's exhalation valve had a gas-collecting collar specially made for the upcoming experiments, thus the modifications. She chose the medium size mask, though she could have used a small if she wanted. Next she donned a harness, stepping into the leg openings and lifting the harness onto her shoulders, fastening the clip in front and tightening the straps as the life support techs at the military base had taught her. Going over to the mask test area, Jill attached her mask hose to the test stand. Jill held her mask to her face, covering her mouth and nose, feeling the purified air blowing into her as she inhaled. Satisfied with the mask's fit and function, she disconnected from the stand and plugged into the oxygen system connector on her harness. Jill rolled up her sleeves. Her left arm was stuck with a needle to administer anesthetic, her right received a blood pressure cuff. Opening her flight suit, electrodes were attached to her chest. Jill knew what she was getting into; today she would be rendered unconscious, paralyzed, and intubated. While knocked out, she would be masked then given artificial respirations to evaluate various methods of resuscitation in case of chemical warfare. She also knew it would HURT! "Looks like we're ready for you, Jill", the officer in charge of the test said. Jill responded, "OK, but I still would like to intubate myself". "Sorry. The test parameters weren't set up for that. Besides, isn't that impossible?" Jill decided not to argue. Soon the IV was flowing, filling her with a disconnected, numb feeling. Her MBU-12p mask fell over to her helmet's side as she laid back, her helmeted head held gently by the anesthesia nurse. A clear anesthesia mask was placed over her nose and mouth, the nurse repeating her mantra in a mechanical fashion cultivated over a thousand inductions; "breathe normally, don't be scared, take deep breaths". Soon Jill was under the drug's influence, unconscious and unable to breathe for herself. The nurse gave the rebreathing bag several hard squeezes, filling Jill's chest which rose visibly even under all the flight gear she wore. Quickly, the nurse removed the mask, Jill's lungs emptying suddenly. The nurse swiftly lifted Jill's tongue with a laryngoscope and passed a well-lubricated 8mm endotracheal tube thru her mouth and windpipe, stopping as the blue cuff passed the vocal cords. She inflated the cuff and connected the tube to the anesthesia machine, again squeezing the bag to fill Jill's flaccid form. With the cuff checked, the nurse taped Jill's tube to the lips and cheeks and continued to ventilate her. Now Jill's limp body was lifted by 4 corpsmen and the gurney she had laid on was removed, and she was placed on the floor. An oxygen sensor was placed on Jill's finger, and the oxygen mask's gas collector hooked to the gas sampling machine. Two enlisted volunteers, a man and a woman, got ready to perform the respiration maneuvers that they might have to perform in the field if a flyer fell victim to nerve agents. They wore camouflage BDUs with chemwar oversuits, and each donned a full face gasmask with filter attached! Jill was out of it. She wouldn't remember a thing. The first volunteer, a woman, took her position over Jill, her knees straddling Jill's midsection while face-to-face with her. The nurse disconnected the ventilator, then placed the MBU-12p mask into position over Jill's intubated mouth and nose, fastening it with the bayonet-style connectors. Then the masked woman over Jill began the artificial respiration by pressing down on Jill's ribcage just below her breasts. She then let off for a few seconds and pressed again. She did this until Jill's oxygen level fell too low to be safe. Quickly the nurse undid the bayonet and pulled the mask aside and replaced the ventilator to her tube. Jill's lungs filled with oxygen-rich, anesthetic laced air! Large, full squeezes from the black rubber rebreathing bag swelled Jill's breasts! Soon her oxygen levels were normal again. Disconnecting the vent, the mask was put back into place. The volunteer again pushed the air out of her victim's lungs, this time lifting her abdomen immediately afterwards in an effort to coax more air into Jill. This time the oxygen level took longer to fall, but it did and Jill was again being forcibly ventilated. The volunteer tried to sweep her brow, forgetting for a moment she was wearing a gasmask. "Are you going to be able to continue?" asked the nurse, gently supporting Jill's ventilator tubing in her hands. "Yeah, I'm just a little hot in here", she replied in a muffled voice, her face showing beads of sweat through the gasmask's large face piece. Now Jill was turned over and the volunteer again straddled her, butt to butt. The other volunteer took his position at Jill's head. Again the ventilator was replaced by the flyer's oxygen mask, then Jill's chest was compressed and released. As the pressure was released, her arms were lifted to make her breathe in more, much like an accordion, at least in theory. Again she was unmasked and ventilated, her endotracheal tube placement and cuff checked. Jill's body would be manipulated like this for another half hour as various theories were tried. She wouldn't remember a thing. Jill awoke from the anesthetic, endotracheal tube in her throat and Foley catheter in her bladder. Her flight suit replaced by golden yellow pajamas, she regained her focus and stared down at herself, watching her breasts rise and fall with the hissings of a ventilator. The vent tubing snaked across her tummy, between her breasts and to the tube that penetrated her mouth and filled her throat in a way she couldn't describe to anyone who had never felt it before. Slowly pulsing, stiffening with every breath forced into her, relaxing as she was allowed to exhale in a controlled sigh, the ventilator tubing held her hostage and gave her life. Jill did notice her IV was piggybacked with painkillers, so she wouldn't feel the bruising and strains her formerly-unconscious body had acquired during the tests. Dr. Marks was away in Japan, no doubt giving self-intubation lessons to the young college girls there. He did give Jill the authority to extubate herself when it was safe for her to breathe on her own. This gave her time to catch up with her old habits!
