1) A 22- year old man was in a motorcycle accident with resultant neck injuries that led to partial paralysis of the upper and lower limbs. Almost immediately his chest felt heavy and he became dyspneic. His pulmonary values:
Vital capacity (supine) = 650 ml
Minute ventilation (supine) = 6 L/min
Respiratory rate (supine) = 30 b/min
PaO2 = 61 mmHg
PaCO2 = 47 mmHg
a)What nerves and muscles are involved in this case?
b)What is causing significantly reduced alveolar ventilation?
