The TREND 110 device is for treatment of obstructive sleep apnea (OSA) in adult patients weighing at least 30 kg. These devices are not intended for use with ventilator-dependent patients.
The TREND 110 device provides continuous positive airway pressure.
The AquaTREND Humidifier accessory provides humidification of the air delivered to the patient.
Hoffrichter TREND 110 devices provide mono-level CPAP treatment levels over the clinician settable range of 4 to 18 cmH₂O.
The TREND 110 CPAP device is provided in a compact lightweight enclosure for easy bedside use. A 2 x 16 character LCD display with keys on the operator panel provides the user with displayed information about the treatment level as well as access to menus for soft-start ramp, clinical prescription (set by doctor, PIN code protected) and hours of operation. TREND 110's power supply automatically supply adapts to regional mains voltage (115 to 230 VAC).
Heated humidification is available by installing the AquaTREND /// heated humidifier accessory. A key with LED indicator permits the user to select the humidification level. Moisture contacting materials in the humidifier and therapy tube meet biocompatibility requirements.

Hoffrichter CPAP devices are prescription use devices, and are not intended for life supporting or life sustaining applications.
This 510(k) summary describes a CPAP device and humidifier accessory. The provided text does not include the typical structure of acceptance criteria and a detailed study report that would fully answer your request.
Medical device approval (especially for 510(k) submissions) often relies on demonstrating substantial equivalence to a predicate device rather than strictly meeting pre-defined performance acceptance criteria in the same way a new drug might. Therefore, the "acceptance criteria" here are generally implied to be "comparable performance to the predicate devices" across various technical and safety benchmarks.
Based on the provided document, here's the information that can be extracted and inferred:
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria (Implied) | Reported Device Performance |
|---|---|
| Electrical Safety | Passed applicable standards |
| Electromagnetic Compatibility (EMC) | Passed applicable standards |
| Shock and Vibration Resistance | Passed applicable standards |
| Environmental Temperature and Humidity Tolerance | Passed applicable standards |
| Static Pressure Performance (comparable to predicate) | Met specified requirements; comparable to predicate devices |
| Dynamic Pressure Performance (comparable to predicate) | Met specified requirements; comparable to predicate devices |
| Humidification Performance (comparable to predicate) | Met specified requirements; comparable to predicate devices |
| Software Verification to Requirements | Verified to requirements |
| Software Validation to Intended Use | Validated to meet intended use by parameter and event testing |
| Biocompatibility of Moisture-Contacting Materials | Met biocompatibility requirements |
| Equivalence to Predicate Devices | Demonstrated to be as safe and effective as, and perform in a manner equivalent to, the predicate devices: Hoffrichter SCALAR/VECTOR Plus, Fisher and Paykel HC200, and Invacare Poseidon. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: Not explicitly stated for any of the non-clinical tests. The document refers to testing "the TREND 110 and AquaTREND III devices" and comparisons "with predicate devices," implying a laboratory or engineering test environment rather than a patient-based test set.
- Data Provenance: Not explicitly stated, but the tests were conducted by the manufacturer, HOFFRICHTER GmbH, in Germany. These are non-clinical engineering and bench tests, not clinical data from patients.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications of Experts
- Not applicable. This document describes non-clinical engineering and bench tests for device functionality and safety. The "ground truth" for these tests would be established by engineering specifications, regulatory standards, and performance characteristics of predicate devices, not by expert medical consensus on patient data.
4. Adjudication Method for the Test Set
- Not applicable. As the tests described are non-clinical engineering tests, there is no mention of an adjudication method in the way it would apply to clinical expert reviews.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
- No. The document explicitly states "Clinical Tests Submitted: (None)". Therefore, no MRMC study was conducted.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done
- Not applicable. This device is a CPAP machine, a physical device that delivers therapy, not an algorithm or AI system for diagnosis or interpretation. The "software" mentioned refers to the embedded control software for the physical device, not a diagnostic algorithm.
7. The type of ground truth used
- For the non-clinical tests (e.g., pressure, humidification, safety), the "ground truth" was based on:
- Applicable industry standards (e.g., for electrical safety, EMC).
- Manufacturer's internal specified requirements.
- Performance characteristics of the predicate devices for comparison.
- No patient-derived ground truth (e.g., pathology, outcomes data) was used, as no clinical studies were submitted.
8. The Sample Size for the Training Set
- Not applicable. This device is a hardware product with embedded control software, not an AI or machine learning model that requires a "training set" of data in the typical sense. The software was verified and validated against requirements and intended use, which is a different process than machine learning model training.
9. How the Ground Truth for the Training Set was Established
- Not applicable. As there is no "training set" for an AI or machine learning model, this question does not apply. The "ground truth" for the device's control software would be its functional specifications and intended performance parameters.

Standard accessories include treatment tubing with integrated measurement tube and headgear. Commercially available masks and swivels are specified.
Hoffrichter CPAP devices are prescription use devices, and are not intended for life supporting or life sustaining applications.
(5) Intended use:
Obstructive sleep apnea (OSA) is a condition caused by closing of the upper airway during sleep. The uvula and soft pallet collapse on the back wall of the upper airway, and when the tongue moves back, the airway is temporarily sealed, causing disruptions in normal respiration and sleep.
Continuous Positive Airway Pressure (CPAP) is an effective treatment for OSA. CPAP devices treat the condition by supplying a constant positive pressure to the airway, most commonly via the nasal passages, in order to prevent the collapse of the soft tissue of the uvula and soft palate during sleep.
Indications for Use:
The TREND 110 device is for treatment of obstructive sleep apnea (OSA) in adult patients weighing at least 30 kg. These devices are not intended for use with ventilator-dependent patients.
The TREND 110 device provides continuous positive airway pressure.

The AquaTREND Humidifier accessory provides humidification of the air delivered to the patient.
Technological Characteristics: (6)
The TREND 110 CPAP device employs the same technological characteristics as the predicate devices. The devices employ a computer controlled blower system which is attached via tubing to a swivel and nasal mask to deliver a prescribed mono-level CPAP treatment to a patient. Devices with humidification employ a hotplate type design to heat a water reservoir to add humidification or a passive (unheated) humidifier.
Hoffrichter CPAP devices employ pressure measurement at the mask via a measurement hose integrated into the breathing hose. This enables improved pressure control and accuracy by the Hoffrichter CPAP devices.
Non-Clinical Tests Submitted: (1) (b)
The TREND 110 and AquaTREND III devices were tested in accordance applicable standards for medical device Electrical Safety, with with with with a Electromagnetic Compatibility, Shock and Vibration, and Environmental Temperature and Humidity. The CPAP devices passed all of the tests.
Static and dynamic pressure testing and humidification testing was performed in comparison with predicate devices. The Hoffrichter TREND 110 and AquaTREND III devices met specified requirements and were comparable to the applicable specifications of the predicate devices.
Software across all platforms was verified to requirements and validated to meet intended use by parameter and event testing.
Clinical Tests Submitted: (None) (2)
Conclusions from Tests: (3)
As described in (b)(1) above, all of the testing demonstrated that the Hoffrichter TREND 110 and AquaTREND III CPAP devices are as safe and effective as and perform in a manner equivalent to the predicate devices, the Hoffrichter SCALAR/VECTOR Plus, Fisher and Paykel HC200, and Invacare Poseidon.
