Extracted text: John halves his tidal volume and doubles his respiratory rate. Which of the following would this result in? W. alveolar ventilation is unchanged X. dead space is unchanged Y. arterial PCO2 is unchanged Z. pulmonary (minute) ventilation is unchanged Select one: a. if only W, X and Y are correct O b. if only W and Y are correct O c. if only X and Z are correct O d. if only Z is correct O e. if all are correct


Extracted text: Air in the trachea at the end of expiration W. contains virtually no CO2 X. has a PO2 of 160 mmHg Y. has the same PCO2 as at the end of inspiration Z. has the same PCO2 as in the alveoli Select one: O a. if only W, X and Y are correct O b. if only W and Y are correct O c. if only X and Z are correct O d. if only Z is correct O e. if all are correct
