Mode Parameter Window Options
The ventilator allows you to select different ventilation modes to optimally manage the patient.
Primary Parameter
The Mode parameter window has four primary parameter choices.
•
AC (Assist/Control)
-- The patient receives either controlled or assisted breaths. When the
patient triggers an assisted breath, they receive a breath based on either the volume or
pressure target.
•
SIMV (Synchronized Intermittent Mandatory Ventilation)
-- The patient receives
controlled breaths based on the set breathing rate. Spontaneous breaths are either
unsupported demand flow or supported using Pressure Support.
Note:
SIMV is an optional mode on the Z Vent ventilator.
•
CPAP (Continuous Positive Airway Pressure)
-- The patient receives constant positive
airway pressure while breathing spontaneously. Spontaneous breaths are either demand flow
or supported using Pressure Support.
•
BL (Bilevel)
-- the ventilator provides two pressure settings to assist patients breathing
spontaneously: a higher inspiratory pressure (IPAP) and a lower expiratory pressure
(EPAP).
Secondary Parameters and Alarm Thresholds/Limits
The Mode parameter window has two secondary parameter choices.
•
Breath target
•
Leak Compensation
Breath Target
•
Volume targeting (V) --
assures a constant volume is delivered to the patient in the
inspiratory time using a constant flow. During volume targeting, the PIP parameter appears
as outlined text.
•
Pressure targeting (P) --
provides a constant airway pressure for the duration of the
inspiratory time using a decelerating flow pattern. During pressure targeting, the Vt
parameter appears as outlined text.
To set (or change) the Breath Target, follow these steps:
1. Press the Mode parameter button twice to highlight the Breath Target parameter
2.
Use the
Dial
to switch between V (Volume Targeting) and P (Pressure Targeting)
3.
Press the
Accept
. button.
Note:
Please note that tidal volume cannot be adjusted in pressure-targeted ventilation. You
may have to adjust PIP to maintain desired tidal volume.
To adjust the PIP target in Pressure Targeted ventilation, follow these steps:
1. Press the
PIP
parameter button.
2.
Use the
Dial
to set the desired PIP target value.
3.
Press the
Accept
button.
In pressure target ventilation, setting the high and low tidal volume limits protect against leaks
and ensures delivery of a minimum tidal volume.
