• Applicant: Breathe Me, Ltd.
• Product Code: BZH · Anesthesiology
• Decision Date: Oct 26, 2018
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 868.1860
• Device Class: Class 2
• Attributes: Pediatric

Intended Use

Peak.me is intended for monitoring FEV1 (Forced exhalation in the first second) and PEF (peak expiratory flow) for home use. The device is designed for adult users and pediatric children over 5 years of age with caregiver supervision. Peak.me is not recommended for children under 5 years of age.

Device Story

Peak.me is a hand-held peak flow meter for home monitoring of FEV1 and PEF. The device consists of a mechanical unit that attaches to a smartphone and a software application. Operation: user exhales through the mechanical unit, which induces acoustic waves with a frequency proportional to airflow; the smartphone's internal microphone captures these waves. The software application analyzes the sound, calculates PEF and FEV1, and displays results numerically and graphically. The app also allows manual input of symptoms and medication usage, and provides guidance. The device is intended for use by patients (adults or children with supervision) to manage asthma or COPD. It benefits patients by providing a portable, easy-to-use platform for tracking lung function trends and disease management.

Clinical Evidence

No clinical study was conducted. Substantial equivalence was established through bench performance testing, including accuracy, precision, and resistance validation per ATS Standardization of Spirometry (1994 Update), background noise validation, and drop testing per IEC 60601-1. A human factors usability study (n=15) demonstrated that all participants could complete tasks with ease and confidence.

Technological Characteristics

Mechanical peak flow meter with mouthpiece and holding mechanism. Sensing principle: acoustic wave generation via airflow-induced rotor chopping, detected by smartphone microphone. No internal electrical components. Connectivity: physical attachment to smartphone. Biocompatibility: ISO 10993-1 compliant. Standards: ATS Standardization of Spirometry (1994 Update).

Indications for Use

Indicated for monitoring FEV1 and PEF in adults and pediatric patients over 5 years of age with caregiver supervision. Not for use in children under 5 years of age.

#### Device Description:

Peak.me is a hand-held Peak Flow Meter device that is intended for monitoring FEV1 (forced exhalation in the first second) and PEF (peak expiratory flow) for home use. The device is designed for pediatric to adult users. Peak.me is not recommended for children under 5 years of age.

Peak.me consists of a mechanical unit, which physically attaches to the user's smartphone, and a software application which analyzes the measurements and serves as a disease management platform. The device uses the smartphone's internal upper microphone as a sensor and does not include any electrical parts.

As the user exhales through the mechanical unit, it produces acoustic waves with a frequency proportional to the exhalation airflow rate, which then propagates to the smartphone's internal upper microphone.

Peak.me software application analyzes the sound and displays the results. Furthermore, the application includes a review of past measurements. It enables manual input of symptoms and medication usage and provides guidance for correct usage and more.

| <b>Peak.me</b><br>Background<br>Noise<br>Validation | Validation of <i>Peak.me's</i> accuracy in the presence of<br>potentially disruptive noises. |
| <b>Peak.me</b> Drop<br>Test Validation | Essential performance tests were conducted following drop<br>test according to IEC 60601-1. The tests were passed<br>successfully. |

Verification and testing have shown that Peak.me device performs according to its specifications.

The Peak.me device was tested and validated with the Samsung Galaxy S6, Samsung Galaxy S6 edge, Samsung Galaxy S7 and Samsung Galaxy S7 edge.

#### Summary of Clinical performance data:

No clinical study was conducted.

Peak.me has the same intended use, clinical indication and technology and no clinical studies were necessary to show substantial equivalency with its predicate device.

#### Human Factor (Usability) Study

A usability study was designed to address the usability concerns and clearness of the Instructions for Use (IFU) and Graphic User Interface (GUI) of Peak.me application and device, while operated by intended users - any person who wishes to monitor his/her lung function. All study participants (15 out of 15 -100%) completed the scenario tasks alone with ease and confidence.

The study results of this usability study demonstrate that the Peak.me device and application are as safe and as effective as its predicate device.

#### Substantial Equivalence:

Peak.me and the predicate device have the same intended use. Both of them have the same clinical indication.

Peak.me device has the same technological characteristic and measuring principles as the Wing Smart FEV1 and Peak Flow Meter (K152276). Both devices induce acoustic waves from airstreams, with a frequency proportional to the exhalation air flow rate.

The design and components of Peak.me device are similar to those of the Wing Smart FEV1 and Peak Flow Meter. Both include a mouthpiece and a mechanical core. The only difference is the sensor's type. While Peak.me is a mechanical

device only that uses the smartphone's upper microphone as an acoustic sensor, in order to record the acoustic tone, the Wing also has an electronic module.

The differences in the design and configuration between the Peak.me and the Wing do not influence the core technology in achieving their intended use.

Both Peak.me device and Wing have a mobile application (App) as the user interface.

Any minor differences in the design do not raise any new types of safety and effectiveness issues. Therefore, Peak.me is substantially equivalent to its predicate device.

#### Conclusions:

As a result, Peak.me device is substantially equivalent to the Wing Smart FEV1 and Peak Flow Meter (K152276) predicate devices.
