For the successful treatment of patients dealing with breathing problems, ventilation is essential. Basically, it is of two types, invasive and non-invasive. Now, invasive ventilation refers to a medical procedure where endotracheal intubation is used. In this treatment, your body parts are invaded by cutting or puncturing the skin. On the other hand, non-invasive ventilation administers the use of breathing support through a mask. In this treatment, no part of your body is invaded/pierced for tending to your breathing issues.For more:https://www.resmed.co.in/healthcare-professionals/diagnosis-and-treatment/respiratory-care/niv
