different trich infection than the std infection. trichomonas in a trach is not the same as trichomoniasis , the std.
if you are washing your hands after caring for this patient , you really aren't at risk for pseudomonas or trichomonas from their trach. If their trach secretions tend to fly out a lot, make sure you are using goggles when suctioning them. Same with it also helps protect you from mrsa too. if you are caring for someone in their home, make sure they are doing all the cleaning and proper laundering that needs done to prevent mrsa from being transmitted in a household.

Sorry you are going to have to tell me what a sputum is.
Trich while it is a STD can be transmitted through use of dirty towles, hot tubs and things like that. So it is possible to get Trich without having sex.
