Question

With what you have learned about pulmonary ventilation, how would you design an artificial respirator to keep patients with paralyzed respiratory muscles alive? How does artificial respiration by a machine compare to mouth-to-mouth respiration?

A) The respirator mimics lung movement by compressing and releasing the chest. It is less effective than mouth-to-mouth respiration.
B) The respirator uses positive pressure to aid inhalation. It is more efficient than mouth-to-mouth respiration.
C) The respirator relies on negative pressure to assist exhalation. It is equally effective as mouth-to-mouth respiration.
D) The respirator utilizes vocal cord stimulation to induce breathing. It is more invasive than mouth-to-mouth respiration.

Answer 1

An artificial respirator can be designed to keep patients with paralyzed respiratory muscles alive. Positive pressure respiration is more efficient than mouth-to-mouth respiration as it ensures a consistent flow of air.

Step-by-step explanation:

A paralyzed respiratory muscles patient can be kept alive by using an artificial respirator. The respirator aids in the movement of air in and out of the lungs, replacing the function of the paralyzed respiratory muscles. It can be designed to use positive pressure to aid inhalation. This method is more efficient than mouth-to-mouth respiration because it ensures a consistent flow of air and can be adjusted according to the patient's needs.
