THE CCV WITH A CONCENTRATOR OR FLOWMETER.
PEEP/CPAP Setting
(Positive End Expiratory Pressure)
will hold a set
pressure at the end of exhalation to keep the lungs partially inflated and
help the exchange of oxygen through the alveoli. The PEEP setting may
be used in any mode and set from 0 to 25 cmH2O. This setting also
controls the pressure level for CPAP (Continuous Positive Airway
Pressure), as described in Continuous Positive Airway Pressure (CPAP)
PIP
(Peak Inspiratory Pressure)
In pressure modes PIP may be set from
15 to 55 cmH
2
O. Measured PIP is reported on the Measured Parameters
panel in all modes.
Vt
is the setting for
tidal volume
and ranges from 40 mL to 2000 mL. In
volume modes this is the single breath tidal volume target.
NOTE: The allowable ranges for I. Time, BPM, and Vt settings are
linked together so as not to exceed the CCV’s maximum flow rate of
60 LPM in volume modes. For example, if Vt is set at 1000 mL, I. Time
will be limited to 1.00 second or more (as 1 L divided by 1/60 minutes
is 60 LPM).
If the maximum flow has been reached, any attempt to increase the
tidal volume will have no effect, and the Vt will remain at its limit. If
the maximum flow has been reached and the I. Time is decreased, the
Vt will automatically decrease as well to maintain the maximum flow.
For example, if the Vt is 1000 mL and the I. Time is 1.00 second,
decreasing the I. Time to 0.75 seconds will automatically decrease the
Vt to 750 mL. See the table below for details.
