Intended Use

The exhalation valves are intended to be used in ventilator circuits consistent with the indicated use of the ventilator to which they are attached.

The single limb model directs flow and allows for pressure monitoring and may be used within hospitals and for home care use.

The dual limb model regulates flow and is for use in hospitals and for home care use.

The exhalation valve are used with adults, pediatrics, and neonates.

The exhalation valves are for single patient use and can be used for a maximum of 30 days.

Device Description

The Altech® Exhalation Valves (Single Limb) are available in 2 configurations intended for use in Single and Dual Limb ventilator circuits. The difference between the configurations is location of exhaust of the expired gas to the room. In the Single limb, the valve is integrated to the limb and expired gas exhausts through the opening below the valve whereas in the valve is attached to the end of the exhalation limb and the expired gas exhausts through device end of the valve.

AI/ML Overview

The Altech® Exhalation Valves (Single Limb and Dual Limb) underwent non-clinical performance testing to demonstrate substantial equivalence to the predicate device.

2. Sample Size Used for the Test Set and Data Provenance:

The document describes non-clinical performance data and comparative testing to a predicate device, rather than a clinical study with a "test set" of patient data. Therefore, information about patient sample size and data provenance (e.g., country of origin, retrospective/prospective) is not applicable in the context of this submission. The "test set" refers to the physical devices undergoing various laboratory tests. The devices were tested pre- and post-aging, after 30 days of use, and after storage conditions.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:

This information is not applicable. The "ground truth" for the non-clinical performance tests is established by published ISO standards and engineering specifications, not by expert consensus on clinical cases.

4. Adjudication Method for the Test Set:

This information is not applicable. Adjudication methods like "2+1" or "3+1" are typically used in clinical studies for resolving discrepancies in expert interpretations of patient data. The non-clinical performance tests rely on objective measurements and established standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

No MRMC comparative effectiveness study was mentioned. The submission focuses on non-clinical performance and substantial equivalence to a predicate device, not on human-in-the-loop performance or comparison of human readers with and without AI assistance.

6. Standalone (Algorithm Only) Performance:

This information is not applicable. The device is an exhalation valve, a physical medical device, not a software algorithm or AI. The tests performed are on the physical device's function.

7. Type of Ground Truth Used:

The "ground truth" for these performance tests is based on:

  • International Standards (ISO): Specifically, ISO 5356-1, ISO 5367, ISO 10993-5, ISO 10993-10, ISO 10993-11, ISO 18562-2, and ISO 18562-3.
  • Engineering Specifications: Predefined acceptance criteria for various parameters like resistance to flow and material composition.
  • Toxicological Risk Assessment: For volatile organic chemicals.

8. Sample Size for the Training Set:

This information is not applicable. There is no "training set" as this is a physical medical device, not an AI or machine learning model.

9. How the Ground Truth for the Training Set Was Established:

This information is not applicable for the same reason as above.

Regulation Name:Non-rebreathing Valve
Product code:CBP

Device Description:

The Altech® Exhalation Valves (Single Limb) are available in 2 configurations intended for use in Single and Dual Limb ventilator circuits. The difference between the configurations is location of exhaust of the expired gas to the room. In the Single limb, the valve is integrated to the limb and expired gas exhausts through the opening below the valve whereas in the valve is attached to the end of the exhalation limb and the expired gas exhausts through device end of the valve.

Principle of Operation:

Exhalation Valves have control line (L port) which passes the pressure from the ventilator to open or close the internal valve.

When starting to deliver an inspiratory breath, the ventilator pressurizes the exhalation valve, closing the exhalation path so that the positive pressure is delivered to the patient. At the end of inspiration, the pressure releases, the Exhalation valve gas pathway opens and the patient's exhaled gases then are vented to the room through the exhalation limb from device end of the valve for dual limb circuits or exhausted through the bottom opening of the valve for the single limb circuit.

Indications for Use:

The exhalation valves are intended to be used in ventilator circuits consistent with the indicated use of the ventilator to which they are attached.

The single limb model directs flow and allows for pressure monitoring and may be used within hospitals

and for home care use.

The dual limb model regulates flow and is for use in hospitals and for home care use.

The exhalation valve are used with adults, pediatrics, and neonates.

The exhalation valves are for single patient use and can be used for a maximum of 30 days

Patient Population:

Adult, Pediatric and Neonates on mechanical ventilation.

Environments of use:

They may be used with ventilators that are indicated for home settings. In all cases the Exhalation valves are part of the ventilator circuit and would be consistent with the indications of the ventilator to which they are attached.

Difference Between Subject and Predicate

Table 2 below presents the differences between the subject device and the predicate which are:

  • Indications for use include the addition of neonate population and adding a Dual limb model in ● addition to the single limb model
  • . The technological characteristics are similar between the subject device and the predicate in that they both use a valve which opened or closed by pressure that is applied by the ventilator. The only difference is that the predicate does not offer a dual limb design which connects to a dual limb circuit thus directing expired gases to the ventilator whereas the single limb design for both devices exhausts the expired gases to the room as they connect to a single limb circuit.
  • . Performance and Specifications are similar and the differences in expiratory resistance and leakage are within acceptable ranges
  • Patient population of adding Neonates
    • The use of the subject device is dependent upon the ventilator to which it is attached and its O indications for use.

Non-clinical Performance Data

Non-clinical performance testing is summarized in the below table.
