treat for shock … and only then tend to such lesser concerns as immobilizing broken bones or bandaging wounds. The old mnemonic “ABC” established the order of treatment: airway, breathing, circulation. First establish an open airway, then restore breathing, and finally stop the bleeding and treat the shock caused by blood loss and trauma.
That order held true in space as well, but things became a lot more complicated. Suit integrity was the first concern; the larger the hole in a Marine’s vac armor, the faster and more explosive the loss of air. In space combat, a corpsman also had to be part suit mechanic. Keeping a Marine’s space armor alive was vital to keeping the Marine inside alive as well.
Mark VIII vac armor was smart enough to seal off a hole to prevent pressure loss. A spongy, inner layer of the armor laminate was a memory plastic designed to press tightly around the man’s body at the point of a leak, serving both as tourniquet and as a seal against further air loss. Sometimes, though, a complete seal just wasn’t possible. This one, for instance. The suit had formed a seal around the hole in order to maintain internal pressure, but the laser burst had punctured the Marine’s thoracic cavity … and penetrated the left lung as well. Air was spilling from the Marine’s bronchial tubes into his chest cavity—a condition called pneumothorax—and the air, mixed with blood, was bubbling away into space through the punctured suit. As the air drained away, the condition became the opposite of pneumothorax—vacuthorax—and massive lung tissue trauma.
And suddenly, things were getting much worse very quickly. As Lee rolled the armored form over, a crusty, glittering patch of frozen blood and water clinging to the wound suddenly dissolved in a spray of red vapor. He caught his mistake immediately. When he’d changed the Marine’s position, he’d moved the wound from shade into direct sunlight. The wound had been partly plugged with blood-ice, but in the harsh light of the sun just above the eastern lunar horizon, the temperature on that part of the armor soared from around −80° Celsius to almost boiling. In seconds, the ice plug had vaporized, reopening both the wound and the partly plugged hole in the armor.
There was no time for anything but plugging that leak. Reaching into the case mounted on his right thigh, he pulled out a loaded sealant gun, pressed the muzzle up against the hole, and squeezed the trigger. Gray goo, a quick-setting polymer heavily laced with programmed nano, squirted over the hole and wound together, almost instantly firming to a claylike consistency, then hardening solid. He checked the Marine’s suit readout again. Internal pressure was low, but steady.
But the guy was still bleeding internally—probably hemorrhaging into his thoracic cavity—and his heart was fluttering, atrial fibrillation. The patient was on the verge of going into arrest.
Lee reached for another tool, a Frahlich Probe, and slammed the needle down against the armor, directly above the heart. The probe’s tip was housed in a nano sheath, which literally slipped between the molecules of the man’s vac armor, then through skin, muscle, and bone to penetrate the patient’s chest while maintaining an almost perfect air-tight seal. Leaving the needle in place, he pulled off the injector, then attached a reader. The device fed his implant a noumenal image of a glistening red, pulsating mass—the beating heart—and let him position the tip of the needle more precisely, at the sinus node at the top of the right atrium. Easy … easy … there!
Now he could program the probe to administer a rapid-fire series of minute electric shocks directly into the sinus node, regularizing the beat. He watched the readout a moment longer as the probe’s computer continued to feed electrical impulses into the patient’s heart. The fibrillation ceased, the heartbeat slowing to a fast but acceptable 112 beats per minute.
The patient’s breathing was labored. He couldn’t tell, but he suspected that the left lung had collapsed. Certainly, it had been badly damaged by both wound and vacuum trauma. With the wound sealed over, the best Lee could do for the patient now was evacuate him.
“Nightingale, Nightingale,” he called. “This is Fox-Sierra One-niner. I need an emergency evac. Patient has suffered massive internal vacuum trauma. Suit leak is plugged and wound is stable. Heart monitor in place and operational. Over!”
A voice came back through his implant a moment later. “Copy that, Fox-Sierra. This is Alpha Three-One, inbound to your position, ETA two-point-five mikes. Ready your patient for pickup, and transmit suit data, over.”
“We’re ready to go at this end. Uploading data now.”
He spent the time checking for other wounds, monitoring the patient’s heart and vitals, and entering the computer code that caused the man’s armor to go rigid, locking him immobile against the chance of further injury. The patient’s condition continued to deteriorate, and Lee was beginning to guess that he’d made a wrong choice, a wrong guess somewhere along the line.
His patient was dying.
Two and a half minutes later, a silent swirl of lunar dust marked the arrival of Alpha 3/1, a UT-40 battlefield transport converted to use as a medevac flier. Bulbous and insect-faced, it settled to the lunar regolith on spindly legs. A pair of space-suited men dropped from the cargo deck and jogged over to Lee and the patient.
Lee stepped back as they attached a harness to the rigid armor. He was already scanning for another casualty. His suit scanners were giving him another target, bearing one-one-seven, range two kilometers. …
“Belay that, Lee,” Gunnery Sergeant Eckhart’s voice told him. “The exercise is concluded.”
“But Gunnery Sergeant—”
“I said belay that! Mount up on the Bug and come on home.”
“Aye aye, Gunnery Sergeant,” he replied. From the sound of Eckhart’s voice, he’d screwed this one up pretty badly. He looked over one of the Marine’s shoulders at the patient and saw the deadly wink of red lights: PATIENT TERMINATED.
Damn, what had he missed? He’d followed procedure right down the list.
He mounted the UT-40, popularly known as a “medibug,” or “bug” for short. The passenger compartment wasn’t much more than an open framework of struts, with a bit of decking underfoot. The two Marines were strapping the patient onto a carry stretcher slung portside outboard, but without the usual formalities of connecting life support and condition monitors. The exercise was over.
The patient, of course, wasn’t really dead, had never been alive to begin with in the traditional sense. It was a high-tech dummy, a quite sophisticated robot, actually, with a very good onboard AI that let it realistically simulate a wide range of combat wounds, injuries, traumas, various diseases, and even potentially fatal conditions such as drop-sickness-induced vomiting, followed by choking inside a sealed helmet. He was called “Misery Mike,” and he and his brothers had helped train a lot of Navy corpsmen for SMF duty. He couldn’t really die of vacuthorax because he wasn’t alive to begin with … but how Lee had treated his problems could mean life or death for Lee’s hopes to ship out with the Marines.
The UT-40’s plasma thrusters fired, the blasts both silent and invisible in the lunar vacuum. Dust billowed out from beneath the bug’s belly as the ugly little vehicle rose into the black sky. After a moment’s acceleration, the thrusters cut out, and the medibug drifted along on a carefully calculated suborbital trajectory, the cratered and dust-cloaked terrain slipping smoothly past a hundred meters below.
He spent the time going over his treatment of the last casualty. He knew he should have been more careful about moving the suit. If he’d left the wound in the shade, kept it below freezing, he might not have damaged the patient’s lungs as badly. But the lungs had already been damaged and vacuthorax would still have been an issue. Damn, what had he missed?
Minutes later, the medibug was descending over the powdery desert of Fra Mauro. Ahead, the Navy–Marine Lunar Facility was spread out in the glare of the early morning sun, its masts, domes, and Quonset cylinders casting oversized shadows across the surface.
The Fra Mauro facility had started life a century and a half ago as a U.N. base, with attendant spaceport. Taken over by U.S.
