Indications for Use

The FloCHANNEL is intended for use during sleep disorder studies to detect respiratory airflow onto a physiological recorder. A filtered disposable nasal/oral cannula attaches to the patient and connects into the input of the FloCHANNEL device. The outputs of the device provide low-voltage signals that are intended to be input into a physiological recorder.

Device Story

FloCHANNEL FC-100 is a breathing frequency monitor used in sleep disorder studies. Device accepts pneumatic inputs from a three-channel nasal/oral cannula (left nasal, right nasal, oral) via a patient interface unit with independently sealed chambers to prevent cross-flow. Internal sensors measure relative airflow; hardware-based signal conditioning transforms pneumatic inputs into analog voltage outputs. Device features a DIP switch for configuring four output voltage ranges. Six output connectors provide signals for Left Nasal, Right Nasal, Oral Airflow, Summed Airflow, Relative Tidal Volume, and IE Marker. Used in clinical settings by healthcare professionals; outputs are fed into a physiological recorder to assist in scoring respiration. Benefits include improved resolution of airflow measurement compared to single-channel sensors, allowing for more detailed respiratory pattern detection.

Clinical Evidence

Bench testing only. Design verification and validation activities confirmed the device met all performance requirements and was clinically equivalent or superior to the predicate device.

Technological Characteristics

Breathing frequency monitor; pneumatic sensing principle; three-channel input (left/right nasal, oral); analog voltage output; six output connectors; DIP switch for signal conditioning configuration; filtered disposable cannula interface; low-power, non-conductive patient connection.

Indications for Use

Indicated for pediatric patients (2 years and older), adults, and geriatric patients undergoing sleep disorder studies to detect respiratory airflow. Contraindicated for infants and children under 2 years of age for respiration or SIDS monitoring.

Regulatory Classification

Identification

A breathing (ventilatory) frequency monitor is a device intended to measure or monitor a patient's respiratory rate. The device may provide an audible or visible alarm when the respiratory rate, averaged over time, is outside operator settable alarm limits. This device does not include the apnea monitor classified in § 868.2377.

## Device Description:

The FloCHANNEL, FC-100, Sleep Diagnostic Device accomplishes its intended purpose The I look I \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ by providing a measure nasal airflow resistance effects. The device simultaneously measures relative airflow of isolated left, right, and oral passages. The FloCHANNEL, measures relative annow of loolated for methods of scoring sleep disordered PC-100, provides analog voltage out hardware amplified analog voltages from three breathing. The outputs provided an have a summed output, and two microprocessor all now sensors, hardware analog voltages to aid in scoring the respiration of a patient.

The FloCHANNEL, FC-100, is dependent on the patient interface unit to be able to compute and detect the respiration patterns of the patient. This accessory is three air compute and delove the respirately pannula. The cannula is of one-piece construction that allows independent pneumatic fluid connection between the FloCHANNEL, FC-100, that the patient's left nasal airway, right nasal airway, and oral airway. The filter shall arra the patient of on habat all ways greater than or equal to 0.1 microns in size between prevent the transfer or partiountios groater and filter per channel on the patient interface unit with independently sealed chambers to prevent cross flow between pneumatic channels.

The FloCHANNEL has an output selection switch that is accessible from the outside of The I loon ANNEE has an ourportion two-selector right-angled DIP switch. The purpose of the enclosure and to a lour pockibility in the output options to be able to configure to a the switch to to ano it signal conditioners. With this switch there is the ability to create four different output voltage ranges.

There are six (6) output connectors on the FloCHANNEL, FC-100. All output connectors There are Six (0) output oonnoctors on the reach output. The outputs are Left Nasal are Nort Julier. This re Nasal Processed Airflow, Oral Airway Processed Airflow, Sum r 10003500 Airflow and Right Nasal Processed Airflow, Relative Tidal Volume, and IE Marker.

#### Intended Use:

The FloCHANNEL is intended for use during sleep disorder studies to detect respiratory rifle i loon a nNVEE is intended for estable nasal/oral cannula attaches to all now onto a pryelence the input of the FloCHANNEL device. The outputs of the the patient and connected into the the that are intended to be input into a physiological recorder.

#### Contraindications:

The FloCHANNEL device can be used for pediatric patients, two years and older and adult patients including geriatric patients. The device is not intended for pediatrics and infants below two years of age for the purpose of respiration or SIDS monitoring.

## Comparison of Technological Characteristics:

Both the Dormio Tech FloCHANNEL and the predicate device are prescription devices, have similar indications for use, similar contradictions, patient populations, patient connections, operating environments, operating temperatures, similar outlet signal voltages and connect to the same physiological recorders for use in sleep disorder studies.

The device has many similar technological characteristics as the predicate device, except that the FloCHANNEL has a relative left naris, right naris and an oral flow input and output signal, whereas the predicate device has only one naris input and output. The FloCHANNEL device also incorporates a state of the art airflow sensor for output signals that that exceed the resolution of the predicate device. The FloCHANNEL device also has two additional low-voltage output signal settings for connection to the widest range of physiological recorders.

#### Summary of Testing:

All risk assessment, design verification and validation activities were conducted in accordance with the device product requirements to demonstrate that the Dormio Tech FloCHANNEL would perform as intended.

- > The FloCHANNEL passed all of the test criteria established in the FloCHANNEL design verification and validation tests.
- The FloCHANNEL was proven clinically equivalent or superior to the predicate device.
- > The differences in the new device and the predicate device do not raise new issues regarding safety or effectiveness. Both devices utilize a filtered patient cannula and are low-powered devices that do not have any direct electrical connections or conductive electrical connections to the patient.

#### Substantial Equivalence:

The device has a similar indications statement as the predicate device. The differences in the device and the predicate device do not alter the effect or raise new issues of safety or effectiveness.

The FloCHANNEL passed all of the tests and acceptance criteria as outlined in the fest procedures. Test data demonstrates equivalence to the predicate device.

Based on the above, we have concluded that the Dormio Tech FloCHANNEL is substantially equivalent to the legally marketed predicate device and is safe and effective for its intended use.
