Which of the following values are indicative of acute respiratory failure and the need for ventilatory support?
1) Maximum inspiratory pressure (MIP) = - 25 cm H₂O
2) Dead space to tidal volume ration (V_D/V_T) = 0.4
3) Vital capacity (VC) = 8 mL/kg IBW
4) pH = 7.20

The critical values for the parameters listed are: maximum inspiratory pressure (MIP)-20 to 0,dead space to tidal volume (V_D/V_T)0.3 to 0.4,vital capacity (VC)< 10 to 15 mL/kg ideal body weight (IBW),and pH < 7.25.
