Question: I'm an author of military science fiction who tends to get my characters injured in the line of duty. Are any of your doctors willing to help me with some book research? I would gladly include their name in the Acknowledgments.

I'm very sorry. Your answer landed in my Spam folder. I have fixed that. Here is the scenario:
Shortly after ejecting from his stricken fighter and while running from enemy pursuers, my pilot character falls on a dead stick that causes a deep laceration from the heel of his right hand almost to the inside of his elbow. (He's right-handed.) He has a military-issue first-aid kit, which he uses to stop the copious bleeding and clean the wound as well as he can under the circumstances, including antibiotic powder in the wound.
He has to travel through mountainous terrain on foot. It's early autumn, so temperatures become quite chilly at night, but no rain. He has survival gear. It will take him a week to get to the pickup point. He's living on survival rations, what edible seeds and insects he can find, and the canteens of water he has with him, which he'll need to refill in a creek (he has water purification tablets to kill amoebas, etc.).
He'll be weakened/in shock from blood loss, become sleep deprived, malnourished, and slightly dehydrated, I expect, as well as incurring a variety of abrasions and contusions. Despite his efforts to prevent it, the arm wound becomes infected and he'll be in bad shape from that by the time he's picked up.
In his weakened state, how likely is he to develop pneumonia as well? I'd rather he didn't; the arm wound should be the most serious risk to him being permanently grounded from flying. However, if that's likely I'm willing to work with it.
Whether or not he ends up with pneumonia will, I expect, determine what kind of immediate and follow-up medical care he'll require. I'd like to continue to correspond, if that is all right with you, once I receive your answer about pneumonia. If we can do that, then I will resubscribe.
Best regards,

Thank you very much, Dr. XXXXXXX This is futuristic science fiction, so he will have advanced technology medical care. Might he be put in a medically induced coma on a ventilator to get him through the most critical stage?
Once they awaken him, how soon will they want to get him on his feet? I expect him to be very weakened, but he doesn't have any leg or back injuries. How long before he will be able to walk unassisted?
They will be able to save his arm, but he will need occupational therapy for some time.
Thank you again, very much. Best regards, Diann Read
