VELA™ ventilator
NPPV
QUICK TIPS

VELA noninvasive positive-pressure ventilation
(NPPV) modes
• NPPV A/C – NPPV with assist control ventilation
• NPPV/SIMV – NPPV with synchronized intermittent mandatory ventilation
• NPPV CPAP PSV – NPPV and continuous positive airway pressure (demand breath)
with pressure support ventilation
Primary breath controls
NOTE: The VELA™ ventilator quick tips card is not intended as a replacement for
the operator’s manual.
You must become completely familiar with the operator’s manual before using
the VELA ventilator.

PEEP Positive end-expiratory pressure 0 to 35 cmH2O
Flow Trig Inspiratory flow trigger 1 to 20 L/min
%O2Percentage of oxygen* 21 to 100%
NPPV Pinsp NPPV inspiratory pressure 0 to 40 cmH2O
NPPV PSV NPPV pressure support ventilation OFF, 1 to 40 cmH2O
*Used only when connected to a high pressure oxygen source

Advanced breath controls in NPPV modes
• PC Flow Cycle – sets the percentage of peak inspiratory flow that
terminates the inspiratory phase of a PC breath.
• PSV Cycle – sets the percentage of peak inspiratory flow that terminates
the inspiratory phase of a PSV breath.
• Bias Flow – sets the continuous flow through the patient breathing circuit.
• PSV Tmax – controls the maximum inspiratory time of a pressure-supported
breath.
Leak compensation
In NPPV modes, the default setting is on. Leak compensation is up to
40 LPM, in addition to the bias flow (10 to 20 LPM, default 10 LPM).
VELA NPPV CPAP PSV set-up – for traditional noninvasive
bilevel ventilation
To set up VELA NPPV CPAP PSV:
1. Press the MODE bar to access the MODE SELECT window.
2. Press NPPV CPAP PSV.

VELA NPPV CPAP PSV set-up (continued)
3. Set primary breath controls parameters:
a. Set the PEEP to the desired pressure value. This setting is equivalent
to CPAP/EPAP pressure.
b. Set the NPPV PSV to the desired pressure value. This setting is the
pressure value plus the set PEEP value that equals the ordered
peak inspiratory pressure (Ppeak) (e.g., if PEEP = 5 cmH2O and
NPPV PSV = 5 cmH2O, then Ppeak = 10 cmH2O).
c. Set the O2and flow trigger levels.
4. Set the advanced settings:
a. Press ADV SETTING to access the ADVANCED SETTINGS window.
b. Press NPPV PSV to access the PSV (flow) Cycle and PSV Tmax controls.
c. Set the PSV Cycle. Generally, set it at 45 to 50% to facilitate the transition
to exhalation.
d. Set the PSV Tmax. A setting between 1 and 1.5 seconds provides backup
termination if large leaks occur during the PSV Cycle.

VELA NPPV CPAP PSV set-up (continued)
5. With NPPV CPAP PSV, the APNEA MODE backup settings only appear
in the MODE SELECT window. Set the APNEA MODE backup:
a. Press Apnea Settings.
b. In APNEA MODE, press Volume or Pressure.
c. Set the primary breath controls for the APNEA MODE backup.
6. Set the alarms:
a. Press LIMITS to access the ALARM LIMITS window.
b. Press the desired alarm, and using the data dial, change the setting.
c. To accept the new alarm setting, press ACCEPT. To restore the previous
setting, press CANCEL.
d. Press LIMITS to exit the ALARM LIMITS window.
7. Press Mode Accept to begin ventilation with the new settings.

VELA monitoring options
The three screens that enable monitoring include:
• Main – displays 5 user-definable parameters plus 3 waveforms.
• Monitors – displays 15 user-definable parameters.
• Trends – displays up to 24 hours of monitored data, 4 histograms and
11 monitored values—all user defined.
To select the desired screen, press the NPPV A/C screen to access the
SCREEN SELECT window.
Patient interface/mask
Specific to NPPV and a dual limb circuit:
• Has no exhalation ports—Is not a mask designed for CPAP or OSA
• Features labeling for noninvasive ventilation use.
• Eliminates ported masks or “whisper valves,” as leakage is not necessary
for proper operation.
Mask fit
To ensure proper fit:
• Use the mask sizing template, which usually comes with the mask, to ensure
the correct size.
• Do not overtighten the mask or headgear, as that can lead to pressure areas.
• Ensure that the facial contours are optimized to prevent leaks (e.g., dentures
are in place, and facial hair is minimal).
