With volume-cycled breaths, worsening airways resistance or lung/chest wall compliance results in increases in peak inspiratory pressure with continued delivery of set tidal volume (unless peak pressure limit is exceeded).
One clinical study (Jones et al 1992a) compared the expiratory flow rates between circuits and found a higher peak expiratory flow rate in the Laerdal circuit at low peak inspiratory pressure (13 cm[H.sub.2]O) compared with a higher peak expiratory flow rate in the Mapleson C at a high peak inspiratory pressure (38 cm[H.sub.2]O).
Lung volumes are certainly related to airway pressures, but you can have significant changes in lung distention without any changes in peak inspiratory pressure. Note what happens when surfactant is administered.
She was placed on a ventilator with settings of SIMV with tidal volume of 70 cc, IMV of 30, PEEP of 5 cm, FI[O.sub.2] of 60% with a peak inspiratory pressure of 20.
The maximum allowable peak inspiratory pressure was set at 30 cm[H.sub.2]O; if this value was exceeded, volume-controlled ventilation was changed to pressure-controlled ventilation.
