Both multi trauma and blood transfusions lead to ARDS.

This is an important question in regards to how you handle this. 

Are you a hospital employee or a private contractor?

If you are an employee, you can submit a complaint to the administration.  The complaint will need to mention "disruptive physician".  Your hospital must have a disruptive physician policy.  In this letter you need to mention "hostile work environment".  This ought to get hteir attention.  If it doesn't then you need to decide whether it is worth getting an attorney or letting it ride.  The term "hostile environment" shoulder get the attention of any CEO worth their salt.  The bottom line is to write letters and have situations documented.
