AI/ML Overview

The provided text is a 510(k) summary for the Wright 1000 Mono Hyperbaric Chamber, a medical device. This document describes the device, its intended use, and its substantial equivalence to a predicate device. However, it does not contain information about formal acceptance criteria, device performance studies, sample sizes, expert ground truth establishment, or any of the other specific details requested in the prompt regarding a clinical or performance study that proves the device meets acceptance criteria.

The 510(k) notification process focuses on demonstrating substantial equivalence to a predicate device, not necessarily on presenting a new, dedicated study proving performance against defined acceptance criteria in the way a clinical trial or performance study would.

Therefore,Based on the provided text, I cannot describe the acceptance criteria or the study that proves the device meets them because this information is not present in the 510(k) summary. A 510(k) submission primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than presenting a novel performance study against predefined acceptance criteria.

The document discusses:

  • The device's physical specifications and manufacturing standards (e.g., max operational pressure, materials, testing conducted during manufacturing, certifications).
  • Approved indications and contraindications for hyperbaric oxygen therapy.
  • Comparison to a predicate device (HYOX System Limited 510(k) No. K874107).

The prompt asks for details that are typically found in a clinical trial report or a dedicated performance study, which are not part of this 510(k) summary document.

To directly answer your numbered points based only on the provided text:

  1. A table of acceptance criteria and the reported device performance: Not provided. The document lists manufacturing specifications and general indications for HBO therapy, but no specific performance acceptance criteria or outcome data from a study.
  2. Sample sized used for the test set and the data provenance: Not provided. No test set or study data is mentioned.
  3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not provided. No test set or ground truth establishment is referenced.
  4. Adjudication method for the test set: Not provided.
  5. If a multi reader multi case (MRMC) comparative effectiveness study was done: Not provided.
  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not provided. This device is a physical hyperbaric chamber, so an "algorithm only" study is not applicable in this context.
  7. The type of ground truth used: Not provided.
  8. The sample size for the training set: Not provided.
  9. How the ground truth for the training set was established: Not provided.

HYPERBARIC TREATMENT:

Hyperbaric oxygen therapy (HBO)is a medical treatment where a patient is placed in a specially designed vessel and placed under pressure greater then sea level and breathes 100% oxygen intermittently. Alveolar oxygen pressure is increased causing a rise in plasma oxygen content which results in enhanced tissue oxygen delivery. the amount of pressure increases and the length of time under pressure are determined by the condition being treated. Treatment pressures are usually between 2 and 3 times atmospheric. treatment usually lasts from 1 to 2 hours at full pressure.

The following are approved indications:

  • l: Air or gas embolism.
  • 2: Carbon monoxide poisoning and smoke inhalation. Carbon monoxide complicated by cyanide poisoning.
  • 3: Clostridial myonecrosis (Gas gangrene).
  • 4: Crush injury, Compartment syndrome, and other acute traumatic ischemias .
  • 5: Decompression sickness.
  • 6: Enhancement of healing in selected problem wounds.
  • 7: Exceptional blood loss (Anemia)
  • 8: Necrotizing soft tissue infections (Subcutaneous tissue, Muscle, Fascia).
  • 9: Osteomyelitis (Refractory).
  • 10: Radiation tissue damage (Osteoradionecrosis).
  • ll. Skin grafts and flaps (Compromised).

    1. Adjunctive hyperbaric oxygen in intracranial abscess.
