The breathing set is an accessory to the F&P 950 Respiratory Humidifier. It is intended for delivery of heated humidified respiratory gases to neonatal, infant and child patients, within the limits of its stated technical specifications.

The F&P 950 Respiratory Humidifier is designed to warm and humidify air after it leaves a commercially available flow source and to maintain the air in a warmed and humidified condition to the point of delivery into the patient via heated tubing.

The F&P 950 Respiratory Humidifier is made up of a heaterbase, sensor cartridge and expiratory heater wire adapter with breathing circuit kits to support the use with adult, pediatric and neonatal patients. Breathing circuit kits enable the use of the F&P 950 Respiratory Humidifier with clinical procedures such as invasive ventilation and nasal high flow.

The device is a programmable electrical medical device that uses sensors throughout the system to humidify the gas. Gas travels through the chamber where it is humidity is requlated through monitoring the gas temperature exiting the chamber to achieve the target humidity level. The gas is then transported to the patient through a heated delivery tube. The gas temperature exiting the heated delivery tube is monitored to minimize the formation of condensate.

The document is a 510(k) Summary for the F&P 950 Respiratory Humidifier and its accessory breathing circuit kits. It outlines the device's indications for use and compares its technological characteristics to a primary predicate device (F&P MR850 Respiratory Humidifier) and several secondary predicate devices for the various breathing circuit kits. The summary also details the non-clinical tests performed to demonstrate substantial equivalence.

Ask a specific question about this device

The bellavista 1000/1000e ventilator is intended to provide positive pressure ventilatory support to adult and pediatric patients and optionally infant and neonatal patients by qualified, trained personnel under the direction of a physician.

Environment of use: hospitals, sub-acute care facilities and intra-hospital transfer

When used on neonatal patients: The environment of use is the Neonatal Intensive Care Unit (NICU).

bellavista is an electronically controlled pneumatic ventilation system. It is powered by AC or DC and also provided with an internal battery. The bellavista pneumatic system supplies respiratory gas whilst the electrical systems control the pneumatics and provides the power supply.

The user can enter values or parameters in the bellavista via the touch screen. These inputs entail instructions for bellavista's pneumatic system to ventilate the patient with a precisely controlled gas mixture. bellavista gathers readings from the proximal flow sensor within the ventilator.

I am sorry, but the provided text does not contain the information required to answer your request. The document is an FDA 510(k) clearance letter and summary for a medical device (ventilator). It describes the device, its intended use, a comparison to predicate devices, and the basis for substantial equivalence.

However, it does not include details about acceptance criteria, specific device performance numerical results, sample sizes for test or training sets, data provenance, expert qualifications, ground truth establishment, or any details about a multi-reader multi-case (MRMC) study or standalone algorithm performance, as these are typically part of a clinical validation study and not usually found in a 510(k) summary for a ventilator.

The document discusses the ventilatory support capabilities and patient populations for which the device is intended, but not the kind of detailed performance metrics usually required for AI/algorithm-based diagnostic devices.
