Doctors take an oath to save lives, but what if as a doctor you didn't know if you were going to live to see another patient?
A University of Kentucky doctor in residency is living that reality right now and hoping for a call that will mean breathing will soon be easier.
Dr. Kevin Bauereis is often times one of the last people patients see before going into surgery.
As a resident in Anesthesiology, Dr. Bauereis sees how modern medicine helps people everyday, what his patients don't know is that he has beaten the odds in his own right.
"When I was younger I was told 18 or 19 would be the life expectancy and I'm 10 years past that," said Dr. Kevin Bauereis.
Kevin's road to becoming a doctor started early on when he was first diagnosed with Cystic Fibrosis, a disease that attacks the lungs, making breathing difficult.
Right now Kevin is among the 30,000 Americans living with CF.
In the seventh grade he realized he wasn't like most kids.
"Sports were kind of going away, I wasn't able to keep up with everybody else so my biggest fill was academics."
Not knowing how long he would live Kevin set his sights on becoming a doctor, no matter the grueling toll it might take on his health.
Now he's in a hospital because he loves it.
"It's get here early and work late."
Many times you will find him stopping not to rest, but to keep up with his daily regiment of medication including a 23 hour continuous antibiotic infusion.
Kevin remembers a time when he didn't take his treatment seriously and the wake up call from his doctor.
"A doctor told me how can you take care of anyone else when you can't take care of yourself."
He changed his tune and now lives for his patients, but he doesn't know for how much longer.
Kevin's health is failing, he needs a double lung transplant.
While he waits, its his patients who give him hope.
" I did an epidural for a young girl who just got a bi-lateral lung transplant, the joy on her face on her first breath is something I remember."
Something this doctor hopes to experience himself.
Dr. Bauereis has taken a leave from UK while he waits for a transplant, he is optimistic.
As for his future he plans, after completing his residency he plans on becoming a Pediatric Anesthesiologist.
Recently his friends and co-workers at the University of Kentucky held a golf scramble to help Kevin and his wife.
The scramble raised $20,000 to help with expenses during the surgery.
