Detailed explanation-1: -Tidal volume is essentially every breath a person takes. It is one of the main determinants of minute ventilation and alveolar ventilation. Minute ventilation, also known as total ventilation, is a measurement of the amount of air that enters the lungs per minute. It is the product of respiratory rate and tidal volume.
Detailed explanation-2: -Tidal volume is the volume of each breath as measured during inspiration or expiration or averaged for the entire respiratory cycle. The value should be normalized to body weight or length. During spontaneous breathing, normal values in healthy neonates range from 5 to 10 mL/kg.
Detailed explanation-3: -Tidal volume is the lung volume representing the normal volume of air displaced between normal inhalation and exhalation when extra effort is not applied. In a healthy, young human adult, tidal volume is approximately 500 mL per inspiration or 7 mL/kg of body mass.
Detailed explanation-4: -Tidal volume (Vt or TV) is the amount of air you move through your lungs each time you inhale and exhale while you’re at rest. Tidal volume typically measures around 500 milliliters (mL) for those assigned male at birth and 400 mL for those assigned female.
