The Masimo SET® (Quartz 2500 Pulse Oximeter and accessories are indicated for the continuous noninyasive monitoring of functional oxygen saturation or arterial hernoglobin (SpO2) and pulse rate (measured by an SpO2 sensor). The Masimo SET "Quartz 2500 Pulse Oximeter and accessories are indicated for use with adult, pediatic, and neonatal patients during both no motion conditions, and for patients who are well or poorly perfused in hospitals, hospital-type facilities, and home environments.
The Masimo LNOP® Series of Sensors are indicated for the Masimo SETYQuartz 2500 Pulse Oximeter and the following:
A single use oximetry sensor intended for adults and pediatrics greater than 30kg.
A single use oximetry sensor intended for pediati.cs and small adults greater than 10 kg and less than 50 kg;
A single use oximetry sensor intended for neonates with good skin integrity less than 10kg;
A single use oximetry sensor intended for neonates with integrity less than 1kg; and
A reusable oximetry sensor intended for adults and pediatrics greater than 30kg.
The Masimo PC Series of Patient Cables are indicated for use with the Masimo LNOP® Series of Sensors and the Masimo SET /Quartz 2500 Pulse Oximeter.
The Masimo SET®/Quartz 2500 Pulse Oximeter and Accessories is a portable stand alone device, connecting cable, and oximetry sensors to noninvasively calculate the functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate.
The monitor consists of a screen that displays the pulse plethysmographic waveform, the pulse rate, SpO2 value, the high and low SpO2 and pulse rate alarm limits, alarms, trends and status messages. It contains the electronic hardware and software that receives and calculates the signals from the LED's to determine the functional oxygen saturation of arterial hemoglobin (SpO>) and pulse rate and provide for the connection to the connecting cable.
The Masimo SET®/Quartz 2500 Pulse Oximeter is available in one configuration as a portable stand alone pulse oximeter that is 10cm high, 27.5cm wide, 25cm deep and weighs 4 kg. The unit is powered either with a voltage input of 100-240 Vac, 50-60 Hz or with a sealed lead-acid battery with an operating time of 5.5 hours and a charge time of 4.5 hours to 80% capacity.
The PC series of connecting cables connects the monitor to the oximetry sensors and transfers LED drive power and the calibration drive to the oximetry sensors from the monitor and the monitor receives the detector signal from the oximetry sensor.
The PC series of connecting cables is available in one configuration and three lengths, 4 feet, 8 feet and 12 feet.
The LNOP® series of oximetry sensors measure the light absorption of blood from two light emitting diodes (LED's). Oxygen saturated blood absorbs light differently as compared to unsaturated blood. The amount of light absorbed by the blood is used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood.
The LNOP® series of oximetry sensors is available in five configurations:
- a single use oximetry sensor intended for adults and pediatrics greater than 30 kg; ●
- a single use oximetry sensor intended for pediatrics and small adults greater than 10 kg and . less than 50 kg:
- . a single use oximetry sensor intended for neonates with good skin integrity less than 10kg;
- a single use oximetry sensor intended for neonates with integrity less than 1kg; and .
- . a reusable oximetry sensor intended for adults and pediatrics greater than 30kg.
The provided text is a 510(k) summary for the Masimo SET®/Quartz 2500 Pulse Oximeter, asserting its substantial equivalence to a previously marketed device, the Masimo SET® 2000 Pulse Oximeter. While it mentions "rigorous testing" and compliance with standards, it does not contain the detailed study information needed to fully answer your request. Specifically, it lacks explicit acceptance criteria, performance metrics, sample sizes, ground truth establishment methods, or information on comparative effectiveness studies, multi-reader multi-case studies, or standalone algorithm performance.
Therefore, I cannot provide a table of acceptance criteria and reported device performance or details about the specific studies. The document focuses on regulatory equivalence and design specifications rather than detailed clinical validation study results.
Here's a breakdown of what can be extracted from the document, and what is missing:
1. Table of Acceptance Criteria and Reported Device Performance
- Not available in the provided document. The document states that the device was "validated through rigorous testing that, in part, support the compliance... to the above mentioned standards." However, it does not specify the acceptance criteria used for these tests (e.g., accuracy +/- X% SpO2) or the specific performance results achieved against those criteria.
2. Sample Size Used for the Test Set and Data Provenance
- Not available in the provided document. The document does not describe a clinical test set, its sample size, or the provenance of any data used for testing.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
- Not applicable/Not available. Since no details of a clinical test set are provided, there is no information about experts or ground truth establishment for such a set.
4. Adjudication Method for the Test Set
- Not applicable/Not available. No information on an adjudication method is provided as no test set details are given.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This device is a pulse oximeter, not an AI-assisted diagnostic tool that would typically involve human readers interpreting cases. Therefore, an MRMC study as described would not be relevant. The document does not mention any studies involving human readers or AI assistance.
6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done
- Partially addressed, but details are lacking. The device is a standalone pulse oximeter, inferring that its performance is reported as algorithm-only, measuring SpO2 and pulse rate. However, the document does not present the specific standalone performance metrics (e.g., bias, accuracy, precision) that would result from such testing. It broadly states the device was "validated through rigorous testing."
7. The Type of Ground Truth Used
- Not available in the provided document for specific performance studies. For pulse oximetry, the typical "gold standard" for SpO2 accuracy studies is arterial blood gas (co-oximetry). While it's implied that such methods would have been used in "rigorous testing," the document does not explicitly state how ground truth was established for the validation.
8. The Sample Size for the Training Set
- Not available in the provided document. No information about a training set for algorithm development is provided.
9. How the Ground Truth for the Training Set Was Established
- Not available in the provided document. No information about a training set or its ground truth establishment is provided.
