Introducing Your Servoi
User Interface
•
The User Interface is where settings are made and ventilation is monitored.
•
You can operate the unit via the soft keys on the touch screen or by means of the direct access knobs(4) or by the fixed keys on the perimeter of the user interface
•
Finally the Main Rotary Dial can also be used to make ventilator changes.
User Interface Slot for PC card with cover
This is the back of the user interface.
New Old
There is a new toggle switch that powers up the Servo-i.
User Interface Loudspeaker which should never be covered
• •
Underneath the cable reel is the control cable. The control cable is 9.5 feet long and must remain connected to the patient unit.
Locking arm to tilt the the screen
User Interface
• •
•
The user interface is designed to separate from the cart. Just lift the user interface straight up, there are no levers to push or hold. The user interface weighs 11lbs (5kg). Screen rotation locking lever
User Interface
•
The user interface can be secured to a table, IV pole etc. by using the locking screw.
Ventilation Record Card
•
Patient ventilatory files can be down-loaded to PC for further analysis, hardcopy, patient file storage - Event log - Trends - Recordings - Open Lung Tool data - Copy screen
Patient Unit
•
The patient unit is where gases are mixed and administered.
•
Flow and pressure are continuously measured by transducers and controlled by a feedback system.
•
The patient unit can operate with one gas source.
Patient Unit
•
As seen here the patient unit can be maneuvered by using the locking handle to push or pull the console.
Patient Unit
•
•
The patient unit is designed so that it can be orientated to the right or left for ease of use. Refer to the user’s manual for the proper procedure.
Patient Unit
The patient unit is also designed to be removed from the cart for transport. Underneath the console there is security knob.
This is the security knob, clockwise secures the patient unit to the console, counterclockwise releases the patient unit.
Patient Unit
•
The cover on the top portion of the patient unit can be removed.
•
Please refer to the user’s manual for specific instructions on how to do this.
Patient Unit
O2 sensor
There are two options to analyze oxygen, one is an oxygen sensor and the other is an oxygen cell. The oxygen sensor seen here is non-disposable and requires no maintenance.
Patient Unit Gas Modules
O2 cell
Here you see an example of the oxygen cell
Patient Unit
1) and 2) are the gas inlets. 3) The gas flow is regulated by the gas modules for air and oxygen. 4) Inspiratory mixing section. 5) O2 sensor or cell. 6) This connection leads to the inspiratory pressure transducer (located inside the ventilator). 7) Inspiratory channel delivers the mixed gases to the patient system.
Patient Unit
Replacing the O2 cell is made easy. Please refer to the user’s manual for the proper procedure.
Patient Unit
•
On the opposite side of the gas modules sits the Expiratory cassette.
•
The Expiratory cassette is a precision instrument and must be handled carefully.
•
The Expiratory cassette can be exchanged between different Servoi Ventilator Systems.
•
Always perform a Pre-use check after exchanging an Expiratory cassette.
Patient Unit
Removing the Expiratory cassette is easily done.
Patient Unit
•
•
The gas flow through the expiratory channel is measured by ultrasonic transducers. The expiratory pressure is measured by the expiratory pressure transducer (located inside the ventilator).
Patient Unit
•
The pressure (PEEP pressure) in the patient system is regulated by the expiratory valve.
•
Gas from the patient system leaves the ventilator via the expiratory outlet. The outlet contains a non-return valve.
