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 are vital capacity (supine) = 650 ml; minute ventilation (supine) = 6 L/min; respiratory rate (supine) = 30 b/min; PaO2 = 61 mmHg; PaCO2 = 47 mmHg. What nerves and muscles are involved in this case? What is causing significantly reduced alveolar ventilation?
