Homework #3

1. Respir Alkalosis, acute, no compensation

_2. P_I02 = (P_B – P_H20) x F_I02

= (765 – 47) x .55

= 394.9 = 395

3. P_A02 = P_I02 – Pac02

r

= 395 – 32 = 355

.8

4. D (A – a) 0₂ = 355 – 71 = 284 (Is this normal)

5. a/A ratio = 71/355 = .2

6. .65 = x + 32/.8 = x +40

.2 .2

------------------ -------------

765-47 718

[[(.65) (718)] - 40] x .2 = x

85 = new P_a02

7. x = 100 + 32

.2 .8

----------------- = 500 + 40

(765 – 47) 718

x = 75%

8. V_T = V _E/f = 10.85 L

14 = 775 ml

9. V_D Anat = 85 kg x 2.2 kg/lb = 187 lbs x 1/2

Tracked = 93.5 cc

10. V_D/V_T ratio = 32 – 18 = 44%

32

11. V_D Phis = V_T x V_D/ V_T = 775 x .44 = 341

_12. V_A = V_T – V_{D Phis}

= 775 – 341 = 434ml

13. V_A =V_E – V_D Phis = 10.85K – (341 x 14) = 6.076L

---

or V_A =(434) (14) 6.076L

^14. (V_T1 x f₁) x P_aC₀₂₁ = (V_T2 x f₂) x P_aC₀₂²

(10.85) x 32 = (V_T2 x 14) x 40

347.2 = V_T2 x 14

40

8.68 = .62L = V_T2

14

15. VT1 x f1 x PaC02 = VT2 x f2 x PaC022

(10.85) (32) = (775) (f) x 50

347.2= (.775) (f)

50

6.94 = f = 9

.755
