Intended Use
The AVL OPTI 1 pH / Blood Gas Analyzer is intended to be used for the measurement of pH, PCO2 and PO2 in samples of whole blood in either a traditional blood gas or clinical Iaboratory setting or point-of-care locations by personnel minimally qualified to perform and report these results.
Device Description
The AVL OPTI 1 is a microprocessor-based instrument using optical fluorescence for the measurement of pH, PCO2 and PO2 in samples of whole blood. A disposable, single-use cassette containing three optical fluorescence sensors is packaged in a sealed, foil pouch which bears a bar coded label with calibration and identification information. Immediately prior to use, the bar coded calibration information is read into the instrument and the cassette positioned in the instrument for calibration verification prior to measurement using a liquid buffer contained within the cassette, und a precision calibration gas contained in a cylinder inside the OPTI 1. In order to provide our customers with an additional level of security in the quality control of results obtained with the OPTI 1, AVL has modified the operation of the OPTI 1 to allow the measurement of a traditional, ampouled, aqueous quality control product prior to any measurement of a patient's blood specimen in the same cassette.

No
The description focuses on microprocessor-based optical fluorescence technology and standard calibration/quality control procedures. There is no mention of AI, ML, or related concepts.

No.
The device is a diagnostic tool that measures pH, PCO2, and PO2 in blood samples, providing information for diagnosis, but it does not directly treat or alleviate a condition.

Yes

Explanation: The device measures pH, PCO2, and PO2 in whole blood samples, which are values used to assess and diagnose a patient's acid-base balance and respiratory status.

No

The device description clearly outlines a microprocessor-based instrument with optical fluorescence sensors, a disposable cassette, and a gas cylinder, indicating significant hardware components beyond just software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that the device is used for the "measurement of pH, PCO2 and PO2 in samples of whole blood." This is a classic definition of an in vitro diagnostic test, as it involves analyzing a biological sample (whole blood) outside of the body to provide information about a patient's health status.
  • Device Description: The description details how the device uses optical fluorescence to measure analytes in a blood sample. This further confirms its function as an in vitro diagnostic tool.
  • Clinical Setting: The intended use specifies that the device is used in "traditional blood gas or clinical laboratory setting or point-of-care locations," which are typical environments for performing IVD tests.
  • Performance Studies: The document describes both nonclinical and clinical tests performed on blood specimens to evaluate the device's performance, which is a requirement for demonstrating the safety and effectiveness of an IVD.
  • Predicate Devices: The listed predicate devices are also pH/Blood Gas Analyzers, which are well-established categories of IVD devices.

The device analyzes biological samples (whole blood) in vitro to provide diagnostic information (pH, PCO2, and PO2 measurements). This aligns perfectly with the definition of an In Vitro Diagnostic device.

(3) Substantial Equivalence

Under 510(k) notification number K944089, AVL currently markets the AVL OPTI 1 pH/Blood Gas Analyzer.

Additionally, as in the former 510(k) submission, the AVL OPTI 1 is substantially equivalent to the AVL Model 995 pH / Blood Gas Analyzer [K895317] and AVL COMPACT 2 pH / Blood Gas Analyzer [K942616].

(4) Description of the new device

The AVL OPTI 1 is a microprocessor-based instrument using optical fluorescence for the measurement of pH, PCO2 and PO2 in samples of whole blood. A disposable, single-use cassette containing three optical fluorescence sensors is packaged in a sealed, foil pouch which bears a bar coded label with calibration and identification information. Immediately prior to use, the bar coded calibration information is read into the instrument and the cassette positioned in the instrument for calibration verification prior to measurement using a liquid buffer contained within the cassette, und a precision calibration gas contained in a cylinder inside the OPTI 1.

Intended use of the device. (ર)

The AVL OPTI 1 pH / Blood Gas Analyzer is intended to be used for the measurement of pH, PCO2 and PO2 in samples of whole blood in either a traditional blood gas or clinical Iaboratory setting or point-of-care locations by personnel minimally qualified to perform and report these results.

Technological characteristics of the device. (6)

The OPTI 1 pH Blood Gas Analyzer uses fluorescence optode technology similar to that used in commercially available products since late 1983 and is unchanged in principle of operation from the originally submitted 510(k) for this device.

Calibration

A disposable, single-use cassette contains all the elements needed for calibration, QC sample measurement, patient sample measurement and waste containment. After reading the calibration information specific to a cassette into the instrument by 'swiping' the cassette packaged through a convenient bar code reader, the cassette is placed into the measurement chamber. The analyzer warms the cassette to 37.0 ± 0.1 ℃, and performs a calibration verification on the sensors for pH, pCO2 and pO2 by passing a precision calibration gas mixture across the optode sensors. The pH channel is calibrated with precision pH buffer solution contained in the cassette.

Summary of nonclinical tests submitted with the premarket notification for the (b) (1) device.

In order to assess the effects of carry-over or memory between the measurement of OPTItrol and a whole blood patient specimen, tonometered whole blood specimens were analyzed on a group of four (4) OPTI 1 instruments in both modes of operation: OPTI-trol and Patient. Each measurement of OPTI-trol was followed by a blood measurement in the same cassette, then a second measurement taken in the same instrument with a second cassette. This protocol was repeated to obtain 3 sets of measurement for each mode of operation for each of 5 levels of gas containing CO2 and then repeated for each of the three levels of OPTI-trol. No significant difference (P
