More ventilator features Flashcards
What are some Adjuncts of ventilators
Tubing compensation
Preoxygenation
Nebulization
what is the purpose of ATC?
- Compensation for resistance of the artificial airway
How does ATC wok?
- Calculates pressure drop at the end of the ETT
- Calculates the pressure/ flow required based on the diameter and length of the ETT
- Changes pressure at wye to compensate
What is the ATC called in Evita
ATC
What is the ATC called in AVEA
AAC
how to access and activate ATC in Evita
set in additional setting , enter this information:
- -> ET OR TT
- -> Internal diameter
- -> compensation %
IN which modes can ATC be used in EVita
Spontaneous
Pressure Support
Pressure control
Auto Flow
How to know if ATC is activated in evita just by looking on the screen?
- visual cue on screen
- ->a tube symbol at the upper right corner
- ->the calculated value of pressure is displayed
how to access and activate AAC in Avea?
Set up screen, enter:
- ETT ID & length
IN which modes can AAC be used in Avea
Active in flow cycled breaths only
–> doesn’t work in volume or time cycle breath
What is the ATC called in Pb840
Tube Compensation (TC) Proportional Assist (PA)
What information is needed to activate the TC in Pb840
% support,
Expiratory sensitivity,
tube I.D.,
and tube type.
What is preoxygenation called in servo-i
oxygen breaths
What is preoxygenation called in avea
increase O2
characteristic of oxygen breath in servo-i
100 % oxygen given for 1 minute
then:
- oxygen concentration will return to the pre-set value
- Can be interrupted by repressing the O2 breaths fixed key during the 1 minute interval
characteristic of preoxygenation in avea
Increases the oxygen concentration delivered to the patient for 2 minutes.
If the key is pressed again within this two-minute period, the maneuver is cancelled
How much does O2 increase in adult/ped mode in AVea
79% above the set % O2
How much does O2 increase in neonate mode in AVea
20% above the set % O2 or 100%, whichever is less
What is the “O2 sensor calibration” in PB840
- Not Equivalent to “Oxygen breaths”
- Delivers 100% oxygen (if available) for two minutes and calibrates the oxygen sensor.
- If you press the O2 key again, system restarts the two-minute interval.
- Press CANCEL to stop the calibration.
What is the “Suction Procedure” in evita?
1.3mins preoxygenation
2.When disconnection for suction occurs,
EvitaXL interrupts ventilation
–> Alarms silenced during disconnection
- After reconnection
- -> 120 seconds post oxygenation (O2 concentration same as preoxy)
- ->MV alarm silenced for 2 minutes
- ->Other alarms silenced 15 seconds
How much o2 does evita give after using suction procedure?
adult patient mode:
–>100 Vol.% O2
pediatric patient mode:
–> O2 concentration that is 25 % higher
than the set concentration
How to assess suction procedure on Evita?
Touch–>Special Procedure–>additional function–> O2 Y suction« screen key,
the key turns yellow.
characterisitc of avea nebulization?
Pneumatic jet nebulizer 20 minutes during inspiration May cancel Up to 8 Lpm Flow decreased to patient 6 lpm
characterisitc of evita nebulization?
Pneumatic jet nebulizer
Adult:
Available in all modes
Flow on inspiration only
Maintains minute volume
Pediatric: Continuous flow No volume compensation Only in Pressure Control or Autoflow No flow sensor
