BACKGROUND: One device that has been proposed to address the need for emergency ventilation is the Vortran Automatic Resuscitator. OBJECTIVE: To test the hypothesis that increasing load (ie, increasing resistance or decreasing compliance) significantly affects minute alveolar ventilation. METHODS: A Vortran Automatic Resuscitator was connected to a passive lung model and we measured load with 8 combinations of 4 compliances (14, 28, 46, and 63 mL/cm H(2)O) and 2 resistances (20 and 42 cm H(2)O/L/s). Source gas flow was either 20 or 40 L/min. We measured tidal volume (V(T)), frequency, inspiratory time, expiratory time, peak inspiratory pressure, and intrinsic positive end-expiratory pressure. We calculated the ratio of inspiratory time to total cycle time (T(I)/T(tot)), minute ventilation, minute alveolar ventilation, and estimated P(aCO(2)). Raw data were summarized with descriptive statistics. A subset of the experimental data (outcome measures for conditions with high and low values for resistance, compliance, and source gas flow) was analyzed with a 2-level factorial design, with standard "design of experiments" procedure, including analysis of variance. Differences associated with p values
