Minute ventilation and end-tidal carbon dioxide. A The two-handed group showing greater inhaled minute ventilation. B The two-handed group showing greater exhaled minute ventilation. C The lower end-tidal carbon dioxide (EtCO2) in the one-handed group might be uncertain due to greater leaks around the facemask during expiration. The EtCO2 value could be reliable in the two-handed group because of its minimal leaks
