Hi Aspirant,

Respiratory therapists earn more.So comparitively there are more scopes in Respiratory therapist.You can research as well as treat patients in some really renowned hospitals since it is a high demanded course.You can really earn well after pursuing this course.Next comes BDS where you can set up your own clinic and if you have enough experience and knowledge you can really earn well since you will treat patients in your own clinic and earn accordingly.However bsc nurse has larger scope but less salary.

Hope this information helps!!
