## DESCRIPTION

The LTV 1000 ventilator is intended to provide continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilator is suitable for use in institutional and attended transport settings, and is applicable for adult and pediatric patients weighing at least 10 kg (22 lbs), who require the following types of ventilatory support:

- . Positive Pressure Ventilation, delivered invasively (via ET tube) or non-invasively (via mask).
- . Assist/Control, SIMV, or CPAP modes of ventilation.
- . Breath types including Volume, Pressure Control, and Pressure Support

{1}------------------------------------------------

The LTV 1000 is a self-contained mechanical ventilator suitable for continuous life support in institutional and attended transport settings. The ventilator is slightly larger than a "laptop computer" and is selfcontained in that it can be operated without the need for externally supplied compressed air. The unit may be operated from external AC power through the use of an external AC/DC converter, or may be operated for approximately one hour using an internal rechargeable battery pack.

The following major features are included:

- Modes: Assist/Control, SIMV, CPAP, Apnea Backup .
- Breath Types: Volume Control, Pressure Control, Pressure Support, Spontaneous .
- Flow Triggering .
- . Oxygen Blending
- . PEEP
- Monitors: Calculated Peak Flow, Exhaled Tidal Volume, I:E Ratio, Mean Airway Pressure, Real Time . Airway Pressure, Peak inspiratory Pressure, PEEP, Total Breath Rate, Total Minute Volume
- Alarms: Apnea, High Pressure Limit, Low Peak Pressure, Low Minute Volume, Disconnect, Low & . Lost External Power, Low & Empty Internal Battery, Oxygen Inlet Pressure

The ventilator uses an internal flow generator to provide the pressurized gas source. All breath types are delivered by an electromechanical inspiratory flow valve. An oxygen blender meters oxygen as required to meet the current setting of the O2% control. Mechanical valves are provided internally for overpressure relief and sub-ambient relief functions.

The patient circuit is comprised of a single leg inspiratory tube connected to an exhalation system located proximal to the patient connection. The exhalation valve system will consist of a piloted exhalation valve, a PEEP valve, and a flow transducer combined in a compact package. Additional small bore tubing is included to transmit the flow, pressure and exhalation drive signals.

## NON-CLINICAL PERFORMANCE TESTING

Pursuant to establishing functional and technical equivalence to the predicate device, a non clinical test program was completed to insure that the device met its stated specifications. Validation activities included running test procedures written to validate the requirements as specified in the following documents:

- System Specification1 .
- . Software Requirements Specification
- . System Hazards Analysis
- . ASTM F 1100-90 Standard Specification for Ventilators for Use in Critical Care

The test procedures were divided into 3 primary categories:

| ASTM tests | Tests that verify the ventilator meets ASTM standards |
|-------------------|---------------------------------------------------------------------------------------------------------------|
| Performance Tests | Tests that verify the ventilator meets performance specifications including<br>tolerance and accuracy issues. |
| Functional Tests | Tests that verify the ventilator meets behavioral specifications (Primarily<br>Software) |

Test procedures were written for individual tests specifying: the requirement being tested, the number of units to be tested, the equipment to be used, test set-up instructions, the data to be recorded. In general, test procedures were written to test each parameter over the entire range of operation while varying other relevant parameters such as patient lung condition and environment. For example, the Set Tidal Volume function was tested over its entire range (50 - 2000 ml) and over worst case combinations of the following parameters:

- . Patient Compliance
- Patient Resistance .
- Temperature/Humidity of Patient breathing gas. .
- Ventilator Operating Temperature. .

A validation report was written that summarizes the results of these tests. The ventilator was found to perform to specifications with exceptions as noted in the validation report. If a parameter was found to be non-compliant, a procedure was described in the report to ensure the anomaly does not present a hazard to the patient or user.

## CONCLUSION

The comparison analysis and validation test results demonstrate the device is substantially equivalent to the predicate device and appropriate for the intended use.

See Section 15: Software.
