The summary describes a traditional mechanical ventilator with standard modes, controls, and monitoring parameters. There is no mention of AI, ML, or any adaptive or learning algorithms in the device description, intended use, or performance studies.
Yes
The device is a ventilator intended to provide ventilatory support, which is a form of medical treatment to assist breathing. Therefore, it is a therapeutic device.
No
The LTV1000 ventilator is described as providing "continuous or intermittent ventilatory support for the care of individuals who require mechanical ventilation." While it monitors various physiological parameters ("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"), these are for the purpose of controlling and delivering ventilation, not for diagnosing a medical condition. Its intended use is to provide therapy (mechanical ventilation), not to identify or characterize a disease or condition.
No
The device description clearly outlines hardware components such as an internal flow generator, electromechanical inspiratory flow valve, oxygen blender, mechanical valves, and a patient circuit with an exhalation system. This indicates it is a hardware device with integrated software, not a software-only medical device.
Based on the provided text, the LTV1000 ventilator is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states that the device is for providing mechanical ventilatory support to individuals who require it. This involves directly interacting with the patient's respiratory system.
- Device Description: The description details a mechanical ventilator with components like a flow generator, inspiratory flow valve, oxygen blender, and patient circuit. These are all involved in delivering gas to and from the patient.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used outside the body to analyze biological samples. The LTV1000 ventilator is used on the body to support breathing.

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 |
| tolerance and accuracy issues. | |
| Functional Tests | Tests that verify the ventilator meets behavioral specifications (Primarily |
| 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.
