Indications for Use
The Astral 100/150 provides continuous or intermittent ventilatory support for patients weighing more than 5kg (11 lb) who require mechanical ventilation. The Astral device is intended to be used in home, institution/hospital and portable applications for both invasive and non-invasive ventilation.
Device Story
Astral 100/150 is a microprocessor-controlled ventilator; uses blower, valves, and pressure/flow sensors to regulate air delivery. Inputs: air via double circuit, single circuit with expiratory valve, or single circuit with intentional leak; supplemental oxygen entrainment at turbine inlet. Outputs: therapeutic/technical alarms, monitored clinical data on LCD screen. Used in home, hospital, and portable settings; operated by clinicians or patients. Provides Assist/Control, SIMV (volume/pressure), Continuous Spontaneous Ventilation (Pressure Support/CPAP), Volume Assurance, and Apnea Ventilation. Healthcare providers adjust clinical parameters via user interface; output assists in managing patient respiratory needs; benefits include continuous or intermittent ventilatory support for patients >5kg.
Clinical Evidence
No clinical data. Bench testing only. Verification activities included accuracy of ventilation volume and pressure controls, waveform performance (flow, pressure, volume), triggering/cycling accuracy and repeatability, endurance, environmental testing, and alarm verification. Side-by-side performance testing against predicates confirmed equivalent flow, pressure, and volume waveforms, and patient trigger reliability.
Technological Characteristics
Microprocessor-controlled blower; pressure, flow, and time regulation. Interfaces: double limb, single limb with expiratory valve, or single limb with intentional leak. Power: AC, DC, and internal battery. User interface: LCD screen, hard keys, LED indicators. Standards: ASTM F 1246-91, ASTM F 1100-90, ISO 10651-2, IEC 60601-1, IEC 60601-1-2.
Indications for Use
Indicated for patients >5kg (11 lb) requiring mechanical ventilatory support; suitable for home, hospital, and portable use; supports both invasive and non-invasive ventilation.
Regulatory Classification

#### Intended Use
The Astral 100/150 provides continuous or intermittent ventilatory support for patients weighing more than 5kg (11 lb) who require mechanical ventilation. The Astral device is intended to be used in home, institution/hospital and portable applications for both invasive and non-invasive ventilation.
#### Device Description
The Astral ventilator system uses a micro-processor controlled blower, which, along with valves and pressure and flow sensors, achieves pressure, flow and time regulation of air delivery. Air is directed to the patient via one of three ventilator breathing circuits; double circuit, single circuit with expiratory valve, or single circuit with intentional leak. Supplemental oxygen can be entrained at the inlet to the main turbine. The device provides both therapeutic and technical alarms, and a user interface allowing adjustment of clinical parameters and display of monitored clinical data. The Astral can use external AC or DC power supply and contains an integrated battery.
The Astral is capable of providing the following types of ventilatory support:
- -Assist/Control and SIMV with either volume or pressure control
- . -Continuous Spontaneous Ventilation in either Pressure Support or CPAP
- ー Volume Assurance and Apnea Ventilation
#### Substantial Equivalence
The Astral has the following similarities to the previously cleared predicate devices:
- -Same intended use
- Same scientific technology ﺖ
- Similar performance specifications -
A comparative summary of the technological characteristics of the Astral device with the primary predicate Trilogy 200 (K093416) is presented below.

#### Non-Clinical Performance Data
Design and Verification activities were performed on the Astral as a result of the risk analysis and product requirements. Testing included accuracy of ventilation volume & pressure controls and monitoring, waveform performance (flow, pressure, volume), accuracy and repeatability of triggering and cycling, endurance and environmental testing, and alarms verification. All tests confirmed the product met the predetermined acceptance criteria. In particular non-clinical side-by-side performance testing was performed for each therapy mode and supplementary feature. Characteristics tested included flow, pressure and volume waveforms, ventilation control parameter accuracy, and patient trigger reliability and synchrony, supporting the claim that the Astral is substantially equivalent to the predicate devices.
The Astral was designed and tested in accordance with the applicable requirements in relevant FDA guidance documents and international standards including:
- FDA Draft Reviewer Guidance for Ventilators (July 1995) -
- FDA Guidance for the Content of Premarket Submissions for Software Contained in -Medical Devices (May 11, 2005)
- ASTM F 1246-91 (2005) Standard Specification for Electrically Powered Home Care -Ventilators
- ASTM F 1100-90 (1997) Standard Specification for Ventilators intended for use in -Critical Care
- ISO 10651-2:2004. Lung ventilators for medical use Part 2: Home care ventilators for ventilator-dependent patients
- -IEC 60601-1:2005 Medical electrical equipment. Part 1: General requirements for basic safety and essential performance.
- IEC 60601-1-2:2007, Medical electrical equipment Part 1-2: Electromagnetic compatibility - Requirements and tests
Clinical testing was not required.

### Conclusion
The indications for use, technological characteristics, and principles of operation are similar to the predicate devices. Performance data supports the claim that the new device is as safe and as effective as the predicate devices. Thus the data in this submission supports the claim of substantial equivalence to the identified predicate devices.
