Used for emergency airway access when conventional endotracheal . intubation and ventilation cannot be performed.

The Arndt Cricothyroid Catheter consists of a connector on the proximal end connected to tubing with an inner diameter. Through the catheter lumen is a dilator. The dilator provides a transition to a wire guide for insertion. The device is placed using the Seldinger technique. The catheter will be included in a set consisting of appropriately sized components.

The provided information does not contain any data regarding acceptance criteria or a study proving device performance in relation to such criteria. The document is a 510(k) premarket notification for the Arndt Emergency Cricothyrotomy Catheter Set, primarily focusing on its substantial equivalence to predicate devices and its intended use.

The text describes the device, its indications for use, and a comparison to existing predicate devices (Melker Cuffed Cricothyroid Catheter Set and The Pertrach). The FDA letter confirms the substantial equivalence determination, allowing the device to be marketed. However, no performance metrics, acceptance criteria, or study results are presented.

Therefore, I cannot fulfill the request to provide:

1. A table of acceptance criteria and reported device performance.
2. Sample sizes used for the test set or data provenance.
3. Number of experts or their qualifications for establishing ground truth.
4. Adjudication method.
5. MRMC comparative effectiveness study results or effect sizes.
6. Standalone performance results.
7. Type of ground truth used.
8. Sample size for the training set.
9. How ground truth for the training set was established.
