Hello,

Respiratory therapists are trained in critical care and cardio-pulmonary medicine. They work therapeutically with people suffering from acute critical conditions, cardiac and pulmonary disease. There are lots of scope available in this field. Being an respiratory therapist you can also be a researcher in this field. So, the salary is more in this field compared to BSc Nursing. Although, BSc Nursing has larger scope but it offered salary amount is low.

Hope it helps!

Good luck!
