I am in the EMS field and had a pt that has active MRSA. The Nursing staff at the Nursing home failed to give this information until the pt vomited on me, at that point I took extra precautions with additional PPE. The pt was vent dependent and when Respiratory Therapy went to change her to our portable vent, she accidentally pulled her foley cath line lose and urine proceeded to spray on myself and my partner. I am not real familiar with active MRSA, nor was my manager when I brought it to his attention. I guess my question is, what is the risk with this type of exposure?
