What is the typical resting minute ventilation (Ve)?

• A. 4 L/min
• B. 6 L/min
• C. 8 L/min
• D. 10 L/min

Answer: (B)

The typical resting minute ventilation, known as Ve, refers to the volume of air that is inhaled or exhaled from a person's lungs per minute while at rest. For a healthy adult at rest, the average minute ventilation is approximately 6 liters per minute. This number is derived from the product of tidal volume (the amount of air per breath) and the respiratory rate (number of breaths per minute). At rest, an average tidal volume is around 500 milliliters (0.5 liters), and when you multiply that by a typical resting respiratory rate of about 12 breaths per minute, the calculation yields a minute ventilation of about 6 L/min (0.5 L/breath × 12 breaths/min = 6 L/min). This value can vary based on several factors such as age, sex, body size, and physical conditioning, but 6 L/min is widely accepted as the normative value for resting minute ventilation. Understanding minute ventilation is important in various clinical settings, such as assessing respiratory function, managing ventilatory support in patients, and recognizing the effects of certain pathological conditions on breathing efficiency.
