Randomized Controlled Trial Comparative Study Clinical Trial[Effects of age, body weight, and ventilatory pattern on the difference between arterial and end-tidal PCO2].
To evaluate the effects of physiological ventilatory patterns on P(a-ET)CO2 gradient and on the alveolar dead space production during controlled mechanical ventilation. ⋯ Ventilatory setting, used in a normal physiological range, don't affect P(a-ET)CO2 difference during mechanical ventilation. Age, body weight and airway pressure of the patient must be considered to obtain a correct value of PaCO2 by the measure of PETCO2.
