Answer :
Final answer:
Correct option is c) .In cases of failed intubations or when using Supraglottic Airways (SGA), spontaneous ventilation is the acceptable method, allowing patients to maintain control over their breathing without mechanical assistance.
Explanation:
When faced with failed intubations or the use of Supraglottic Airways (SGA), the acceptable form of ventilation is spontaneous ventilation. This type of ventilation allows the patient to control their own breathing efforts rather than relying on mechanical assistance. In the context of failed intubation or when SGAs are used, ensuring that the patient can maintain spontaneous breathing is crucial for preventing further complications. It's important to understand the terms related to ventilation, such as external respiration, which is the exchange of gases between the environment and the blood; interpulmonary respiration, the exchange of gases between the blood and the alveoli; internal respiration, the exchange of gases between the blood and body cells; and pulmonary ventilation, the physical movement of air in and out of the lungs. Additionally, the concept of residual volume is vital, as it refers to the volume of air left in the lungs after a forced exhalation, which helps prevent the alveoli from collapsing and maintains open airways for gas exchange.
