No
The device measures various cardiac parameters but does not state that it is used for treatment or therapy. Its function is limited to monitoring and providing data for diagnostic purposes.
Yes
Explanation: The device measures various cardiac parameters such as Cardiac Index, Cardiac Output, and Ejection Fraction, which are used to assess the physiological state of a patient, thus aiding in diagnosis. The "Intended Use / Indications for Use" section explicitly states it "noninvasively measures cardiac output and other related cardiac parameters," which are diagnostic indicators.
No
The device description explicitly states it consists of a "small, portable, lightweight electronic unit" and "a six lead, patient cable using commercially available silver/silver chloride skin electrodes," in addition to the software. This indicates it includes hardware components.
Based on the provided information, the PhysioFlow Q-Link is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The PhysioFlow Q-Link measures physiological parameters directly from the patient's body using electrical bioimpedance. It does not analyze blood, urine, tissue, or other biological samples.
- The intended use describes direct measurement of cardiac parameters from the patient. The device is applied to the patient's skin via electrodes to obtain measurements.
- The device description details a noninvasive monitor that attaches to the patient. This further confirms that it is not analyzing samples taken from the body.
Therefore, the PhysioFlow Q-Link is a non-invasive medical device used for monitoring physiological parameters, not an in vitro diagnostic device.

Device Description
The PhysioFlow Q-Link is a noninvasive, hemodynamic monitor that utilizes thoracic electrical bioimpedance technology to measure cardiac output and related cardiac parameters. It consists of a small, portable, lightweight electronic unit that attaches to the patient via a six lead, patient cable using commercially available silver/silver chloride skin electrodes. Monitor data is transmitted to a host computer running the PhysioFlow PF107 software. Communication to the host computer is via USB wired technology. The PhysioFlow PF107 software performs multiple tasks including signal processing and analysis, measured parameter computation, user interface display and control, measurement process control, event marker management, and output display/report generation. Available accessories include the patient and USB cables.

Device Description:
The PhysioFlow Q-Link is a noninvasive, hemodynamic monitor that utilizes thoracic electrical bioimpedance technology to measure cardiac output and related cardiac parameters. It consists of a small, portable, lightweight electronic unit that attaches to the patient via a six lead, patient cable using commercially available silver/silver chloride skin electrodes. Monitor data is transmitted to a host computer running the PhysioFlow PF107 software. Communication to the
1
host computer is via USB wired technology. The PhysioFlow PF107 software performs multiple tasks including signal processing and analysis, measured parameter computation, user interface display and control, measurement process control, event marker management, and output display/report generation. Available accessories include the patient and USB cables.
Indications for Use:
Indicated for use in adults only.
The PhysioFlow Q-Link noninvasively measures cardiac output and other related cardiac parameters. These parameters include:
| CI | Cardiac Index |
|---|---|
| CO | Cardiac Output |
| CTI | Contractility Index |
| dZ / dt max | Maximum value dZ / dt |
| EDV | End Diastolic Volume |
| EF | Ejection Fraction |
| HR | Heart Rate |
| LCWI | Left Cardiac Work Index |
| PEP | Pre-Ejection Period |
| SV | Stroke Volume |
| SVR | Systemic Vascular Resistance |
| SVRI | Systemic Vascular Resistance Index |
| TFI | Thoracic Fluid Index |
| VET | Ventricular Ejection Time |
| ZO | Base Impedance |
The PhysioFlow O-Link is intended for use under the direct supervision of a licensed healthcare practitioner or personnel trained in its proper use within a hospital or facility providing healthcare.
Intended use and comparison to predicate devices:
The PhysioFlow O-Link and PhysioFlow Enduro Model PF-07 have the same intended for use/indications for use. Both devices are intended for use in adults only to noninvasively measure cardiac output and other related cardiac parameters, including the following: cardiac output, cardiac index, contractility index, maximum value dZ/dt, end diastolic volume, ejection fraction, heart rate, left cardiac work index, pre-ejection period, stroke volume, systemic vascular resistance, systemic vascular resistance index, thoracic fluid index, ventricular ejection time, and base impedance. Both devices are intended for use under the direct supervision of a licensed
2
practitioner or personnel trained in its proper use within a hospital or facility providing healthcare.
Technological characteristics and comparison to predicate devices:
The PhysioFlow Q-Link is a modification of the PhysioFlow Enduro Model PF-07. It utilizes the same thoracic electrical bioimpedance technology to measure the same cardiac output and related cardiac parameters. It remains similar to the predicate device in size, but excludes the battery power source, on-board data storage, and wireless Bluetooth technology features of the predicate device. The PhysioFlow Q-Link will fill a position amongst the PhysioFlow family of devices for users who find the battery life or wireless communication features of the PhysioFlow Enduro Model PF-07 to be inconvenient or cumbersome, but still desire a small, portable unit. Like the PhysioFlow Enduro Model PF-07, the PhysioFlow Q-Link continues to interface with a MS Windows based host computer running the previously-cleared PhysioFlow PF107 software (K103283). No changes to the PhysioFlow PF107 software were required to enable its use with the PhysioFlow Q-Link.
The differences in technological characteristics between the subject and predicate devices do not raise new types of safety or effectiveness questions. Accepted scientific methods, such as performance (bench) testing, do exist for assessing the effect of the differences in characteristics.
Summary of performance data:
1
Design verification tests were performed on representative samples of the PhysioFlow O-Link as a result of a comprehensive product development and risk management plan. All tests were verified to meet the pre-specified acceptance criteria. As such, the PhysioFlow Q-Link is considered substantially equivalent to the PhysioFlow Enduro Model PF-07.
