WOB and Paediatric Mechanical Ventilation

"The ventilator mode is switched to PS ventilation. The level of PS is set to meet the level of PS set when the patient is ventilated in the SIMV-PS mode. The patient will be in the PS mode until he or she clinically shows increased work-of-breathing (tachypnoea and the presence of nasal flaring and intercostal and/or interjugular retractions indicate increased work of breathing). This sprinting is performed on the theory that the respiratory muscles can be slowly trained to sustain complete spontaneous breathing. Also, theoretically this sprinting allows a better global and regional distribution of the tidal volume in the lung."
