Minute ventilation

|
|
Stroke Volume
|
|
|
Inspiratory reserve volume

|
|
Tidal volume

Explanation:
Detailed explanation-1: -Minute ventilation is the tidal volume times the respiratory rate, usually, 500 mL × 12 breaths/min = 6000 mL/min.
Detailed explanation-2: -Tidal volume (TV) measures the amount of air that is inspired and expired during a normal breath. On average, this volume is around one-half liter, which is a little less than the capacity of a 20-ounce drink bottle.
Detailed explanation-3: -Normal minute ventilation is 5-8 L/min. A patient with a high minute ventilation has a high drive to breathe (pain, sepsis, etc) and may not be ready to breathe comfortably without the ventilator. If a patient’s minute ventilation is too low, they may retained CO2 if not mechanically ventilated.
