All of the following will increase lung compliance except? Question 14Select one:a.increased transpulmonary pressureb.decreased fibrotic tissue surrounding alveolic.increased production of surfactantd.increased elastic fibres in lung tissuee.reduced alveolar surface tension
Solution
Para responder a esta pregunta, primero debemos entender qué es la "compliance" pulmonar. La "compliance" pulmonar se refiere a la capacidad de los pulmones para expandirse y contraerse. Un aumento en la "compliance" pulmonar significa que los pulmones se expanden más fácilmente.
Ahora, analicemos cada opción:
a. Increased transpulmonary pressure: La presión transpulmonar es la diferencia entre la presión alveolar y la presión pleural. Un aumento en esta presión facilita la expansión de los pulmones, lo que incrementa la "compliance" pulmonar.
b. Decreased fibrotic tissue surrounding alveoli: El tejido fibroso reduce la elasticidad de los pulmones. Disminuir el tejido fibroso alrededor de los alvéolos aumentaría la "compliance" pulmonar, ya que los pulmones se expandirían más fácilmente.
c. Increased production of surfactant: El surfactante reduce la tensión superficial en los alvéolos, facilitando su expansión. Un aumento en la producción de surfactante incrementa la "compliance" pulmonar.
d. Increased elastic fibres in lung tissue: Las fibras elásticas permiten que los pulmones se retraigan después de la expansión. Un aumento en las fibras elásticas haría que los pulmones sean más rígidos y menos capaces de expandirse fácilmente, lo que disminuiría la "compliance" pulmonar.
e. Reduced alveolar surface tension: La tensión superficial en los alvéolos tiende a colapsarlos. Reducir esta tensión facilita la expansión de los alvéolos, lo que incrementa la "compliance" pulmonar.
Por lo tanto, la opción que no aumentaría la "compliance" pulmonar es:
d. Increased elastic fibres in lung tissue
