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 mlMinute ventilation (supine) = 6 L/minRespiratory rate (supine) = 30 b/minPaO2 = 61 mmHgPaCO2 = 47 mmHga)What nerves and muscles are involved in this case?  b)What is causing significantly reduced alveolar ventilation?c)What are the values for the tidal volume and the alveolar ventilation for this Individual? How is the residual volume affected?e) What is causing the dyspnea in this individual?
