Mindray A9 Operating Instructions

Set Ventilation Operations
6 - 12 Operator’s Manual of Anesthesia System
SIMV-VC parameters:
•Vt: tidal volume
•RR: respiratory rate
• Tinsp: time of inspiration
• F-Trig/P-Trig: flow rate trigger level/pressure trigger level
• ΔPsupp: support pressure
• PEEP: positive end-expiratory pressure
• Plimit: pressure limit level
• Tpause: inspiratory pause
• Trig Window: trigger window (supports buffer time of synchronous inspiration of patients,
in the later expiratory stage in the Auto ventilation mode, with its duration being a percent of
the set breathing cycle)
• Tslope: rise time
• Exp%: expiration trigger level (change to the expiratory stage when the expiration trigger
level (peak flow * expiration trigger level) is reached.)
SIMV-PC parameters:
• Pinsp or ΔPinsp: peak inspiratory airway pressure or relative inspiratory pressure
•RR: respiratory rate
• Tinsp: time of inspiration
• F-Trig/P-Trig: flow rate trigger level/pressure trigger level
• Tslope: rise time
• ΔPsupp: support pressure
• PEEP: positive end-expiratory pressure
• Trig Window: trigger window
• Exp%: expiration trigger level
SIMV-VG parameters:
•Vt: tidal volume
•RR: respiratory rate
• Tinsp: time of inspiration
• F-Trig/P-Trig: flow rate trigger level/pressure trigger level
• ΔPsupp: support pressure
• PEEP: positive end-expiratory pressure
• Plimit: pressure limit level
• Trig Window: trigger window
• Tslope: rise time
• Exp%: expiration trigger level
NOTE: Before activating a new automatic ventilation mode, ensure that all
related parameters are set appropriately.
