Impact Uni-Vent 750 Portable Ventilator

Description - The Uni-Vent 750 Portable Ventilator is a portable electronically

controlled, time cycled, pressure limited ventilator. It is controlled by anon board microprocessor which continuously monitors the patients airway

pressure, all control settings, alarm parameters and power signals.

Indications- Extended duration transport that requires ventilator assistance or complete

airway/ventilation control

Contraindications- None

Side Effects- Possible hypoxia due to malfunction of ventilator

Possible Pnumothorax from over pressure

Special Considerations- Adequate oxygen supply for the transport

External 110 power supply

Operation of the Uni-Vent 750 Portable Ventilator

Control Module: Front panel of ventilator where the controls and indicators are located.

This panel is accessed by unlocking and lifting the clear cover. All of theventilator functions and settings are done from the Control Module.

Mode Selector Switch: Turn the ventilator on and allow it to perform a self check. After the self

check has completed you can use the Control Module to make adjustmentsto the settings and select the operation mode according to the patients

needs.

CTRL Cycles in accordance with Rate, Inspiration time and Flow

Adjust settings.

ASSIST Cycles in accordance with Rate, Inspiration timeand Flow

Adjust, but will sense the patients attempts at spontaneous respiration

and assist the patient with the Flow and Inspiration time settings.

Control takes over when the rate is to low or no spontaneous respirations

are sensed.

SIMV Will intermittently deliver a controlled breath at the Ratecontrolsetting, and synchronize to the patients spontaneous respirations. The

patient breathes at their normal rate and volume until the next controlled

ventilation.

Flow Adjust: The Flow Adjustwill allow for the user to adjust the Tidal volume

delivered. It is used in conjunction with the Inspiration Time.

(Calibrated for 50psi input pressure)

Example: Flow Adjustset at 500 ml/SEC and Inspiration Timeset at 1.5SEC will deliver a Tidal Volume of 750 ml. (see the back of the ventilator

for a Computation Chart)

Tidal volume = 6 Liters/Kg

Rate control: To select the ventilation rate, press the RATE button next to the Ratecontrol knob. The button lamp will illuminate and the digital display will

light and allow adjustments to be made.

12-20 breaths per minute

Inspiration Time: To select the inspiration time, press the INSP button next to the

Inspiration Rate control knob. The button lamp will illuminate and thedigital display will light and allow adjustments to be made.

Inspiration time 1-1.5 SEC

High/low pressure controls:Adjust High/Low pressure alarms. press the HIGH or LOW button

next to the High/LOW knob. The button lamp will illuminate and thedigital display will light and allow adjustments to be made. (10 above and

5 below the hospital Peak Inspiratrory Pressure)

PEEP controls: Select the PEEP setting if required.

Alarms: Alarm Status indicator will alert you to any problems that may occur.This function is designed to give you an auditory and visual alert. The

alarm can be temporarily muted or cancelled for a period 30 seconds to 5

minutes depending on the alarm type

1. Low Pressure/Disconnect activates when the airway pressure falls below the low pressure

alarm setting control setting, or if the patient circuit is disconnected for any reason.

2. High Pressure activates if the airway pressure exceeds the High pressure control setting for2 seconds or for 4 consecutive breaths.

3. Peep Not Set activates when monitored Peep exceeds the settings by +2 or -1 for threeconsecutive breaths.

4. Alarm Mute/Cancel indicates that the alarm mute/cancel button has been pressed. All

ventilation alarms will mute for 30 seconds. External Power Low/Fail and Low Battery alarmswill last for 5 minutes. All alarm conditions will reset once the problem has been corrected

5. External Power Low/Fail activates when the external power supply has failed or been

disrupted

6. Battery Low/Fail activates when the internal battery falls below 12.2 volts. (It will shut

down if the battery falls below 11.2 volts.) An external power supply should be supplied if this

alarm activates.7. Apnea activates in Assist and SIMV modes. The ventilator will default to a special Assist-Control Ventilation program during this alarm. It cannot be muted. Once the problem has been

corrected the alarm can be cancelled.

Ventilator Connections

GAS IN: Connect the Green Oxygen tube to the GAS IN connection (male thread) on thefront of the ventilator.

Requires 50psi to function properly

GAS OUT: Connect the ventilator end of the circuit to the GAS OUT port on the front ofthe ventilator.

Transducer: Connect the GREEN transducer tube to the Transducer port on the front of

the ventilator directly below the gas out port. You may have to cut the connector

off the end of the tube.

Exhaust Port: Connect the CLEAR tube to theEXHAUST port silver nipple located on the

side of the gas out port. You may have to cut the connector off the end of the

tube.

External Power: Connect the external power cord to the EXT POWER port on the front of theventilator.

Operator Performance ChecksBefore connecting the ventilator to the patient

1. Verify operating Power connection.

2. When using external power source insure that the EXT POWER indicator lamp isIlluminated.

3. Verify completion of self-check.

4. Insure all hoses, tubing and fittings are properly connected and secure.

5. Review all ventilator settings.

Patient Connections

Patient Valve: Connect theGREEN transducer tube to the Patient Valve on the larger of the twonipples using the white elbow.

6/6

Connect the Clearexhaust tube to the smaller nipple located on top of the Patient

Valve.

Connect the circuit to the endotracheal tube and assess the quality of the

ventilations being provided

Consider the use of an End Tidal Co2 Detector.

In a high noise environment or where auscultation may be difficult or impractical, an End Tidal Co2

detector is mandatory as an aid in assessing the patients ventilatory status and tube placement.

.

Manual Over-Ride

Manual Trigger located on the bottom of the Control Module will allow manual over-ride of the

control settings.
