VT:
Regulation of the propelled volume by the ventilator in the mandatory inspiration.
Flow Waveform:
To change the flow waveform.
PSV:
Regulates the level of pressure support.
Rise Time:
To vary the PSV pressurization.
Synchronized intermittent ventilation with pressure-controlled mandatory
inspiration and spontaneous inspirations with pressure support.
(SIMV [PCV] +
PSV)
Definition and Operative Proceeding:
Similar to the previous mode, in this
synchronized ventilation form the patient receives, during the mandatory inspiration, a
pressure controlled inspiration with decelerating flow which is sent to the patient in a
synchronized form. During the spontaneous breathings the patient ventilates with
pressure support.
Specific Controls for the SIMV [VCV] + PSV mode:
PCV:
Regulation of the pressure of the mandatory inspiration.
PSV:
Regulates the level of pressure support.
Rise Time:
To vary the PCV and PSV pressurization.
Mandatory Minute Ventilation with Pressure Support.
(MMV + PSV)
Definition and Operative Proceeding:
It is a spontaneous ventilatory mode where
the patient breathes with pressure support at a preset initial value, and there is
regulation of a minimum minute volume. During every minute, if the volume is not
reached, the pressure support level increases progressively until that volume is
attained.
Specific Controls for the SIMV [VCV] + PSV mode:
Minute Volume:
Regulation of the minimum minute volume.
PSV:
Regulates the initial level of pressure support.
Rise Time:
To vary the PSV pressurization.
Pressure Support Ventilation with Tidal Volume Assured.
(PSV + VT Assured)
Definition and Operative Proceeding:
It is a spontaneous ventilatory mode where
the patient breathes with pressure support at a given value combined with the
regulation of a target tidal volume. If during some breath, the set volume is not
reached, the descending ramp flow changes to continuous flow. This effect produces
a rise in the inspired volume until the target volume is reached with a concomitant rise
in the airway pressure.
Specific Controls for the SIMV [VCV] + PSV mode:
VT:
Regulation of the minimum tidal volume.
PSV:
Regulates the level of pressure support.
Rise Time:
To vary the PSV pressurization.
