Define tidal volume in lungs.
Answers
Tidal volume is a measure of the amount of air a person inhales during a normal breath. Traditional preset tidal volumes higher than 10 ml/kg have been proved to be associated with increased risk of pulmonary barotrauma and should be avoided. High tidal volumes also decrease venous return and reduce cardiac output.
Additional formulas:
Ideal body weight (IBW), men = 50 kg + 2.3 * [height (in) – 60]
IBW, women = 45.5 kg + 2.3 * [height (in) – 60]
Usual tidal volume target = 6-8 mL/kg IBW.
Answer:
Tidal volume (symbol VT or TV) is thelung volume representing the normalvolume 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
