However, this may also be caused by pulmonary dysfunction with an increase in dead space volume. Therefore, correlation between the end tidal CO2 and an ABG/VBG measurement is needed to confirm the diagnosis of hypocapnia.

WebWhat is a normal tidal volume? Tidal volume is the volume of gas that is moved in and out of the lungs per breath. The normal tidal volume is 6 to 8 ml/kg, regardless of age. Total lung capacity (TLC) is the volume of gas present in the lung with maximal inflation. The normal range for TLC is 60 to 80 ml/kg.

WebAug 5, 2024 · However, if the patient is ventilated with small tidal volumes, then a greater fraction of each breath will be wasted on dead space ventilation. Consequently, a strategy of high-frequency, low-tidal volume breaths will tend to achieve less CO2 clearance for any specific total minute ventilation.

WebJul 12, 2024 · Exercise During exercise, the gas exchange requirements of the lung increase due to an increased oxygen consumption and increased carbon dioxide production. In addition, both the respiratory rate and tidal volume increase, hence alveolar ventilation also increases. This increases the rate of gas exchange and minute volume. WebSep 28, 2024 · The main function of the respiratory system is gas exchange (O 2 and CO 2 ).
