Twin Patients $X$ And $Y$ , Both Have Resp Irations of 12 Breaths/min, Tidal Volumes

Twin patients, $X$ and $Y$ , both have resp irations of 12 breaths/min, tidal volumes of 500 $\mathrm { mL }$ , and dead space of $100 \mathrm {~mL}$ . Patient $X$ 's resp iratory rate decreases by half and the tidal volume doubles. Patient Y's resp iratory rate doubles and the tidal volume decreases by half. After 2 minutes, what conditions would best describe their alveolar gases, as compared with normal?
Patient X Alveolar Ventilation $\quad \underline { \text { Patient } \mathrm { Y } }$ Alveolar Ventilation
$\begin{array} { l } &\text { Alveolar } \mathrm{pO}_{2}&\text { Alveolar } \mathrm{pCO}_{2}&\text { Alveolar } \mathrm{pO}_{2}&\text { Alv eolar } \mathrm{pCO}_{2}\\A.&\uparrow&↓&\uparrow&↓\\B.&↓&\uparrow&↓&↓\\C.&\uparrow&↓&↓&\uparrow\\D.&\uparrow&\uparrow&\uparrow&\uparrow\\E.&\downarrow&\uparrow&\downarrow&\uparrow\\\end{array}$
