Introduction
the patient at a preset inspiratory pressure, I:E ratio or inspiratory
time, rise time factor (how quickly inspiratory pressure rises to
achieve the set inspiratory pressure), and oxygen concentration at a
minimum respiratory rate. A spontaneous breath allows the patient
inspiratory flows of up to 300 L/min, with or without pressure
support ventilation (PSV). On the 760 Ventilator, you can set the rise
time factor and exhalation flow sensitivity (that is, the point at
which the ventilator cycles from inspiration to exhalation) in PSV.
The ventilator begins apnea ventilation if no breath (patient- ,
ventilator-, or operator-initiated) is delivered within the selected
apnea interval. Apnea ventilation is active during all modes. On the
740 Ventilator, only VCV breaths are available in apnea ventilation.
On the 760 Ventilator, VCV or PCV breaths are available in apnea
ventilation.
The 760 Ventilator also offers the ability to perform respiratory
mechanics calculations and maneuvers as a standard feature using
the EXP PAUSE (to calculate auto-PEEP) and INSP PAUSE (to calculate
patient resistance and compliance) keys.
