A patient has an adequate ventilatory reserve if which of the following is true? A) Ability to double the resting minute ventilation B) Normal PaCO₂ and minute ventilation less than 10 L/min C) MIP = -55 cm H₂O D) V_D/V_T less than 0.4

Question

Quizplus · Accepted Answer

Adequate ventilatory reserve means the ability of the patient to increase their minute ventilation to meet the increasing metabolic demands during exercise or physical activity. A patient has adequate ventilatory reserve if they can double their resting minute ventilation. So, option A is the correct answer. Option B refers to normal PaCO2 and minute ventilation which can be a sign of respiratory stability but not necessarily an indicator of ventilatory reserve. Option C refers to maximal inspiratory pressure and Option D refers to the ratio of dead space to tidal volume, which are not directly related to ventilatory reserve.
