Question
3 When a patient has a procedure called a tracheostomy, a hole is cut into the trachea and a tube is inserted through which the patient breathes. This allows the air to bypass the upper respiratory tract and enter the trachea directly, Could this have potential negative consequences for the patient? Explain. (Hint: Consider the function of the nasal cavity and other upper airways.) 4 A pulmonary Dulmonay cenubolus s a piece of a blood clot, adipose tissue, or other substance that lodges somewhere in the a Wety bas a pulmonary embolus lodged his pulmonary arteriol htenor vena cava to the pulmonary arteriole wher n one of his pulmonary arterioles. Trace the pathway of blood flow from his the embolus is lodged.Explanation / Answer
Answer:
Explanation: The disadvantage of tracheostomy with respect to the nasal cavity and upper airways is that the air will enter directly to trachea. The direct air applied will be dry and cold. This will also lead to drying of respiratory tract due to air bypassing upper respiratory tract or nasal passage, oxygen supplementation and a decrease in mucociliary mechanism. This all is due to the fact that the main function of nasal cavity is to make air warm, to make air moistured and it is also used to filter the air by the ciliary action before it reaches the lungs. The main function of the hairs of nose and mucus that is lining the upper respiratory tract and nasal cavity is to filter dust particles, pollen grains from plants and other contaminants before they reach lower respiratory tract. Overall, the upper respiratory tract is used to make air warm and moistured and filtration before going to main respiratory tract. In tracheostomy upper respiratory tract/nasal cavity is bypassed, therefore, there are enough chances that there will be cold air and lead to problems and infections due to dust, pollen and other contaminants.
