Tidal volume (symbol VT or TV) 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.
    The tidal volume range of our emergency ventilator JX100C is 50~1200ml; and the tidal volume range of our emergency ventilator JOGGER is 50~2000ml.
