Question

What is the minute alveolar ventilation for a 150-lb (68-kg) patient with the following parameters?

VE 8.4 L
Respiratory rate 14/min
PetCO2 30 mmHg

1) 6.3 L
2) 5.3 L
3) 4.4 L
4) 3.2 L

Answer 1

The minute alveolar ventilation can be calculated using the formula: Minute Alveolar Ventilation = (Tidal Volume - Dead Space) * Respiratory Rate.

Step-by-step explanation:

The minute alveolar ventilation can be calculated using the formula:

Minute Alveolar Ventilation = (Tidal Volume - Dead Space) × Respiratory Rate

Given the following parameters:

• VE 8.4 L (Ventilation)
• Respiratory rate = 14/min
• PetCO2 30 mmHg (partial pressure of end-tidal carbon dioxide)

We need the tidal volume to calculate the minute alveolar ventilation. Without the given tidal volume, we cannot provide the accurate answer.
