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. recycle store in enumclaw

"Websubmaximal exercise, ventilation increases linearly with oxygen consumption and carbon dioxide production. This occurs primarily through an increase in tidal volume (i.e., the volume of air inhaled and exhaled per breath). At higher or near-maximal intensities, the frequency of breathing becomes more pronounced and minute ventilation (V • E " - How does increasing tidal volume affect co2
