# How to calculate my “approximate” mortality rate while in ICU?

To make a long story as short as possible for context, I was rushed to the ER while in cardiac arrest back in 2014. Heart stopped beating momentarily and lost oxygen to the part of my brain. None of the doctors were able to completely figure out the cause of what triggered the event, but I was ultimately diagnosed with two main illnesses which I want to focus on as they are the most significant to me in the calculation I want to get to, if that's possible.

I was primarily diagnosed with Sepsis and Acute Respiratory Distress Syndrome. When I was discharged from the ICU, the ER doctor who treated me told me that when I was admitted, my mortality rate was over 80% (thank you so much to the amazing staff at my hospital, forever grateful!!).

I know he factored in the cardiac arrest and other issues I had when initially admitted, but I would like to know my likely/average/rough estimate/I'm-not-sure-what-correct-term (if there is one) mortality rate was, factoring in only the sepsis and ARDs. I read on Wikipedia (not the best source, I know...) that the mortality rate for sepsis ranges from 30%-80%, and ARDs is anywhere from 35%-50%. Is there a way to calculate some form of mortality rate from these two ranges? Or would it not make sense? I was 18 at the time, smoked ~half a pack of cigarettes a day, tad bit underweight (I believe I was around 120ish at 5'9", curse you ADHD medication!), but otherwise was a healthy male for being 18yo and stupid, if that makes any difference.

Thank you so much for your help, insight and expertise offered to a 23yo who is curious about what treatment, or combination of treatments, helped save my life 5 years ago!

P.S. For those wondering why I want to know some sort of figure for this, I'm writing a post asking those who are healthy and able to donate plasma to consider doing so, as I received a substantial amount of PRP treatments, as well as a multiple bags of donated plasma while in ICU. I knew I received this treatment, but I just read this research article by the American Thoracic Society, which was published on June 24, 2014 - less than 3 months before I got sick and was treated with this therapy. I wonder if my Pulmonologist who treated me in the ICU came across this article during his research, as he stayed up many nights during my stay reading case studies, and his first treatment he requested permission from my parents was therapeutic hypothermia, which I know is considered controversial/ineffective by certain medical professionals, so considering the fact he was trying everything he could to save me, I'm not sure if this PRP treatment for sepsis resulting in ARDs was also considered new (admittedly haven't read the entire paper!).
