HFT150 is for spontaneously breathing adult and pediatric patients (10 kg and up) who would benefit from receiving high flow warmed and humidified respiratory gases. The flow may be from 2 - 60 L/min depending on the patient interface. HFT150 is used in hospital and professional healthcare environments.

Device Story

HFT150 is a heated humidifier with integrated flow source and heated breathing tube; delivers warmed, humidified gas flow (2-60 L/min) with supplemental oxygen (21-100%) to patients. Comprised of motorized blower assembly and integrated humidification tub. Operated by nurses, respiratory therapists, or doctors in hospital/professional healthcare environments. Software monitors ambient temperature, humidity, and flow to optimize humidity delivery and minimize condensation. Includes optional integrated Nonin Xpod 3012LP pulse oximetry for SpO2 and pulse rate monitoring. Disposable nasal cannulas, heated tubes, and water tubs used for patient interface. Provides audible/visual alarms for temperature, flow, and oxygen fraction. Benefits patients by providing respiratory support via high-flow therapy; integrated monitoring reduces need for standalone pulse oximetry devices.

The HFT150 includes an integrated oxygen module, delivering an oxygen range of 21% to 100% to the patients. The HFT150 humidifier is comprised of two connected functional units. One is a motorized blower assembly that provides air flow and the delivery of supplemental oxygen to patients via an integrated oxygen module. The blower speed is directly related to total delivered flow and is controlled by software with a flow sensor. The blower assembly output connects directly to an integrated humidification tub. {5}------------------------------------------------ Image /page/5/Picture/0 description: The image shows the logo for Invent Medical Corporation. The word "invent" is written in a sans-serif font, with the "in" in light gray and the "vent" in blue. Below the word "invent" is the phrase "MEDICAL CORPORATION" in smaller, gray, sans-serif letters. The logo is simple and modern, and the use of color helps to make it stand out. The second functional unit of the HFT150 is a heated humidifier. The tub is integral to the HFT150. Software monitors ambient temperature, humidity, and flow to optimize the humidity delivery to the patient and minimize condensation in the patient circuit. The HFT150 is protected from contaminants and pathogens by an integral anti-bacterial filter. The nasal cannulas, heated tubes, and water tubs are disposable and are for single use only. The HFT150 may be operated by nurses, respiratory therapists, or doctors and water tubs are disposable and are for single use only. The HFT150 may be operated by nurses, respiratory therapists, or doctors. # Indications for Use HFT150 is for spontaneously breathing adult and pediatric patients (10 kg and up) who would benefit from receiving high flow warmed and humidified respiratory gases. The flow may be from 2 - 60 L/min depending on the patient interface. HFT150 is used in hospital and professional healthcare environments. | HFT150 Indications for Use (Subject Device – K233707) | AIRVO 2 Series Humidifier (Primary Predicate Device – K131895) | Assessment of Differences | |--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | HFT150 is for spontaneously breathing adult and pediatric patients (10 kg and up) who would benefit from receiving high flow warmed and humidified respiratory gases.

The minor differences between predicate and subject devices are identified in the table above and are described further below. Both the HFT150 and the predicate device support the delivery of oxygen flow up to 60 L/min. The subject device utilizes an internal mechanism for oxygen flow delivery. The predicate device utilizes an external mechanism for oxygen flow delivery. Both the HFT150 and the predicate device support a nasal cannula patient interface. The predicate device also supports a tracheotomy and mask interface. The HFT150 utilizes both a rotary control knob and LCD touch screen for selecting device settings. The predicate device utilizes hard keys for selecting device settings. The HFT150 provides users the option of an integrated Nonin Xpod 3012LP for SpO2% and Pulse Rate display and alarms for low SpO2%, high SpO2%, High Pulse Rate, and Low Pulse Rate. Although both the subject device and predicate device provide supplemental oxygen, the predicate device does not provide an integrated Pulse Oximetry option. For either the subject device or predicate device, the user may choose to use an external, standalone pulse oximetry device. As such, this submission includes the reference device, ApneaLink Air (K143272), which also utilizes the same well-established Nonin Xpod 3012LP technology. Additionally, a second {8}------------------------------------------------ Image /page/8/Picture/0 description: The image shows the logo for Invent Medical Corporation.
