Minute & Alveolar Ventilation Minute ventilation (V E) is the total volume of gas entering (or leaving) the lung per minute. It is equal to the tidal volume (TV) multiplied by the respiratory rate (f). Minute ventilation = V E = TV x f At rest, a normal person moves ~450 ml/breath x 10 breath/min = 4500 ml/min.

Although alveolar ventilation is usually defined as the volume of fresh air entering the alveoli per minute, a similar volume of alveolar air leaving the body per minute is implicit in this definition.

When alveolar ventilatory rates decline, the rate at which CO 2 is eliminated by the lungs correspondingly decreases, thus yielding increased partial pressures of alveolar CO 2 (PA CO 2 ). Alveolar ventilation (a product of respiratory rate and tidal volume) is normally carefully controlled by the actions of central and peripheral chemoreceptors and lung receptors. 14 Ventilation is driven by both the arterial partial pressure of oxygen (Pa o2) and the arterial partial pressure of carbon dioxide (Pa co2), with Pa co2 being the most important driver. 14 The body attempts to correct hypoxaemia and hypercarbia by increasing both tidal volume and respiratory rate. Rate of uptake is dependent on 1) alveolar ventilation rate 2) partial pressure of gas (concentration effect) 3) breathing system.

1. respiratory minute volume is Vt (tidal volume) x RR or f (resp. rate). ex: 500cc x 12 = 6000cc breathed in a minute. thats your respiratory volume. 2. alveolar volume is (vt -dead space) x rr . the average dead space is about 150cc give or take a few. ex: 500cc - 150 = 350 x 12 = 4200cc alveolar volume (ventilation)

Normal ranges for the variables used are included in the table below: Although alveolar ventilation is usually defined as the volume of fresh air entering the alveoli per minute, a similar volume of alveolar air leaving the body per minute is implicit in this definition. The alveolar ventilation rate changes according to the frequency of breath, tidal volume, and amount of dead space. PA refers to alveolar partial pressure of a gas, while Pa refers to the partial pressure of that gas in arterial blood. Gas exchange occurs from passive diffusion because PAO2 is greater than PaO2 in deoxygenated blood. The target alveolar ventilation is 4.7 L/min which is the alveolar ventilation in this patient with a minute ventilation of 150 ml/kg/min PBW and with a medium instrumental dead space (HME 50 ml, catheter mount and connections 20 ml). The alveolar ventilation for an average sized adult with a tidal volume of 500mL breathing at a rate of 12/per minute would be calculated as: What's the alveolar ventilation? AV= (500mL-150mL) X 12/minute AV=4200mL or 4.2L/per minute The target alveolar ventilation is 4.7 L/min which is the alveolar ventilation in this patient with a minute ventilation of 150 ml/kg/min PBW and with a medium instrumental dead space (HME 50 ml, catheter mount and connections 20 ml).
