B.O.L.T, Pulse Oximeter model Base unit (VA01) along with a pulse oximeter probe (VA01-2) is a non-invasive device intended for spot checking of functional oxygen saturation of arterial hemoglobin (SpO2) and pulse rate (PR) from the fingertip of adult users.

The B.O.L.T patient monitor system base unit VA01 is elegantly designed with small form factor. The devices NIBP, IRT thermometer and Pulse Oximeter connects to the base unit. The device has two LED indicators that display power status and Bluetooth connectivity status. The device has an on/off slide switch on the side and USB power socket. The device has one accessories port with Lemo connector to connect IRT Thermometer and Pulse Oximeter, one at a time. There are two other ports to connect the twin tubes of the NIBP Cuff. The base unit has a rechargeable lithium polymer battery and device should be used only in battery mode and it should not be used while charging. The power adapter is given only for charging the device. The B.O.L.T. NIBP device model VA01-0 connects to the VA01 Base unit's twin port and measures both systolic and diastolic blood pressure and pulse rate via a standard oscillometric method. The oscillometric method senses the vibrating signal via the closed air pipe system and utilizes a microcontroller in the base unit to automatically sense the characteristics of the pulse signal. Unlike with the traditional measuring method, based o6i the Korotkov sound, with the oscillometric method the use of a stethoscope is not required. Through simple calculations, this method provides accurate blood pressure readings: the systolic pressure is defined as the blood pressure when the cuff pressure oscillating amplitude begins to increase, while the diastolic blood pressure is defined as the pressure when the cuff pressure oscillating amplitude stops decreasing. The device includes a plastic enclosure and external wraparound cuff, and it requires an external device (e.g. a smartphone) to display results and perform user interaction.

  • NIBP: Omron model HEM 907 (K032305)
  • IRT Thermometer: Braun PRO 4000 (K031928), and DT-K11E (K172861) as a contact reference thermometer.
  • Pulse Oximeter: Contec Medical Systems model CMS-50D (K082641) (as a reference device) and Radiometer model ABL 800 Basic with Co-oximeter (for measuring SaO2 from arterial blood sample).

4. Adjudication Method for the Test Set

• The document does not describe any specific adjudication method (e.g., 2+1, 3+1) for the test sets. The accuracy of the B.O.L.T devices was evaluated by comparing their measurements directly to those obtained from the established reference devices and standards.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No MRMC comparative effectiveness study was done. The studies described are device-to-reference device comparisons, not human reader performance studies with or without AI assistance. The B.O.L.T is a vital signs monitor, not an AI-assisted diagnostic imaging tool that would typically involve MRMC studies.

6. Standalone Performance

• Yes, standalone performance (algorithm only without human-in-the-loop performance) was effectively done for each module. The studies evaluate the accuracy of the B.O.L.T device's measurements (NIBP, SpO2, Temperature) against established reference devices, without the direct involvement of human interpretation of the device's output for diagnostic purposes beyond reading the measurements themselves. The device's operation is controlled by an application, but the core measurement accuracy is assessed as a standalone system.

7. Type of Ground Truth Used

• The ground truth used was established by comparison with measurements from predicate/reference medical devices and in the case of SpO2, also with outcomes data (SaO2 values from arterial blood samples) measured by a Co-oximeter which is considered a gold standard for blood oxygen saturation. This is a form of empirical validation against established clinical standards and reference instruments.

8. Sample Size for the Training Set

• The document describes clinical validation studies (test sets) but does not provide any information regarding the sample size used for the training set for the device's development or algorithms. The device's technological characteristics are based on established methods (e.g., oscillometric method for NIBP, infrared for temperature, photoelectric for pulse oximetry), rather than deep learning algorithms requiring large training datasets.

9. How the Ground Truth for the Training Set Was Established

• Since no specific training set for an AI/ML algorithm is described, the ground truth establishment for a training set is not applicable here. The device's underlying principles are based on known physiological measurement techniques and are validated against established medical device standards and reference instruments.
