The summary describes a device that measures PEF and FEV1 and displays the results. There is no mention of AI, ML, or any algorithms that would interpret or analyze the data beyond simple measurement and display.
No
The device is described as a "medical instrument" for "monitoring" respiratory diseases by measuring and displaying PEF and FEV1, not for treating them.
Yes
The device is described as a "medical instrument which is intended to be used for the monitoring of asthma and other chronic respiratory diseases" and it "measures both Peak Expiratory Flow (PEF) and Forced Expiratory Volume-One Second (FEV1)". The purpose of monitoring diseases and measuring these parameters is to aid in diagnosis and disease management. The summary of performance studies also states that it "can appropriately provide information regarding a subject's PEF and FEV1 measurements and can appropriately identify PEF measurement of suspect quality," which points to its diagnostic capabilities.
No
The device description explicitly states it is a "pocket-sized, personal electronic device" that includes an LCD, control buttons, a mouthpiece, and an RJ-11C connector, indicating it is a hardware device with integrated software, not a software-only device.
Based on the provided information, the AirWatch II Zone is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze samples taken from the human body. The AirWatch II Zone measures respiratory parameters (PEF and FEV1) directly from the patient's breath. It does not analyze blood, urine, tissue, or other samples collected from the body.
- The intended use is direct physiological measurement. The device is used to monitor the patient's respiratory function in real-time by measuring airflow. This is a direct physiological measurement, not an in vitro analysis of a sample.
Therefore, the AirWatch II Zone falls under the category of a medical device that performs physiological measurements, but it is not an IVD.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The AirWatch II Zone was tested on 20 study subjects in each of the following studies: Validation/Measurement Quality Study; Home Use Study; User Guide Study; and Quick Reference Guide Study.
In summary, the Validation/Measurement Quality Study demonstrated that the AirWatch II Zone can appropriately provide information regarding a subject's PEF and FEV1 measurements and can appropriately identify PEF measurement of suspect quality. Other studies demonstrated that consumers can safely and effectively use the AirWatch II Zone under conditions of actual use; that consumers can interpret the AirWatch II Zone's display readings and take appropriate actions; and that the Quick Reference Guide, User Guide, AirWatch II Zone's physical design, and other human factors characteristics are appropriate for consumers.

Predicate Device:
ENACT Products, Inc. AirWatch Monitor (K941226)
Description of Device:
The AirWatch II Zone is a pocket-sized, personal electronic device which monitors respiratory status by measuring peak expiratory flow (PEF) rate in liters per minute and forced expiratory volume in one second (FEV1) in liters.
The AirWatch II Zone includes an LCD for displaying PEF and FEV1 information to the consumer, three control buttons, a removable mouthpiece, and an RJ-11C telephone connector which can be used to transfer data stored in the AirWatch to a remote computer.
Indications for Use:
AirWatch II Zone is a medical instrument which is intended to be used for the monitoring of asthma and other chronic respiratory diseases. The instrument measures both Peak Expiratory Flow (PEF) and Forced Expiratory Volume-One Second (FEVI). The instrument is designed for use by consumers from 5 years of age to adults.
Summary of Technological Characteristics:
There is one technological difference between the AirWatch II Zone and its predicate device, the addition of an effort check warning feature.
1
measurements which do not accurately represent airway status. The AirWatch II Zone checks every measurement with three effort check tests. Warning symbols appear on the display when a measurement fails any one or more of these tests. The appearance of the warning symbols will alert the consumer that the monitor has detected a measurement of suspect quality as a result of poor technique.
The AirWatch II Zone also differs from its predicate device by conforming to the new American Thoracic Society 1994 Standards versus the 1987 Standards.
Summary of Non-Clinical Performance Data:
The AirWatch II Zone and its predicate device meet all applicable electrical, mechanical and environmental performance requirements given in the Reviewers Guidance for Premarket Notification Submissions, Appendix A.
The AirWatch II Zone and its predicate device also conform to the National Asthma Education Program's Statement on Technical Standards for peak flow meters. The AirWatch II Zone meets the American Thoracic Society 1994 Standards for accuracy, precision, linearity, and back pressure. The predicate device meets the American Thoracic Society 1987 Standards.
Summary of Clinical Performance Data:
The AirWatch II Zone was tested on 20 study subjects in each of the following studies: Validation/Measurement Quality Study; Home Use Study; User Guide Study; and Quick Reference Guide Study.
In summary, the Validation/Measurement Quality Study demonstrated that the AirWatch II Zone can appropriately provide information regarding a subject's PEF and FEV1 measurements and can appropriately identify PEF measurement of suspect quality.
