When this issue occurs, anesthetic agent delivery will be interrupted and requires clinician intervention. If this is not provided, the patient may experience decreased anesthetic agent effect.

Why it matters: The FDA recorded an enforcement action against this device. Most device recalls are corrections rather than removals, so the device often stays in use while the manufacturer issues a fix.
