Ventilation modes The Respironics V60 Ventilator operates in the following ventilation modes:
• CPAP (continuous positive airway pressure) mode
• S/T (spontaneous/timed) mode
• PCV (pressure-controlled ventilation) mode
• AVAPS (average volume-assured pressure support) mode (optional)
• PPV (proportional pressure ventilation) mode (optional)
Table 4-1 summarizes the characteristics of these modes. Note that on the
ventilator, the Timed breath indicator means the breath is ventilator triggered,
while the Spont breath indicator means the breath is patient triggered.
