A tracheotomy is an operation to make an opening in the trachea if there is an upper respiratory obstruction of airflow. Explain how ventilation is possible via this opening and why you don’t need to use your nose or mouth to bring air into your lungs.
What will be an ideal response?
Answer: Tracheostomy is a process in which a hole is made in the trachea so that the patient can take in the air and expel the air through the tracheostomy opening.
By making a hole we are bypassing the nose or mouth... And the air can enter during inspiration (where negative intrapleural pressure develops) through the opening and air leaves the lungs through the opening during the expiration (where the positive intrathoracic pressure pushes air out if lungs)
