The summary describes a device that measures and displays physiological data (EtCO2 and respiration rate) and guides the user through breathing exercises. There is no mention of AI, ML, or any algorithms that learn or adapt based on data. The device appears to be a biofeedback system.
Yes
The device is indicated as an adjunctive treatment for symptoms associated with panic disorder (PD) and/or posttraumatic stress disorder (PTSD), which are medical conditions, and clinical studies show a reduction in CAPS-5 scores for these conditions.
No
The device is intended as a treatment for the reduction of stress and as an adjunctive treatment for symptoms associated with panic disorder and PTSD, not for diagnosing these conditions.
No
The device description explicitly mentions the "Freespira Sensor" which is a hardware component used to measure exhaled carbon dioxide and respiration rate.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is described as a "relaxation treatment for the reduction of stress by leading the user through guided and monitored breathing exercises." It is indicated as an "adjunctive treatment of symptoms associated with panic disorder (PD) and/or posttraumatic stress disorder (PTSD)." This describes a therapeutic intervention, not a diagnostic test performed on biological samples.
- Device Description: The device measures and displays exhaled carbon dioxide (EtCO₂) level and respiration rate (RR) to guide breathing exercises. While it measures physiological parameters, it does not analyze biological samples (like blood, urine, tissue, etc.) to diagnose a condition or provide information about a person's health status in that way.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analysis of biological specimens.
- Providing diagnostic information about a disease or condition.
- Use in a laboratory setting (though some IVDs are point-of-care).
The device is a therapeutic tool that uses physiological measurements to guide a treatment, not a diagnostic test.

Summary of Performance Studies
Palo Alto Health Sciences Inc. performed a prospective, single arm, un-blinded investigation of Freespira in the indicated population. Patients with a primary diagnosis of PTSD (military and non-military, combat and non-combat) were enrolled into a four-week Freespira program. At enrollment, and then at specified intervals, patients underwent assessment using validated questionnaires (PHQ-9, SF-36, PDSS, CGC-S and CAPS-5 30-day score). In addition, every time a patient used Freespira, their EtCO2 and RR data were stored locally (on the tablet) and securely uploaded to a cloud server for clinician review.
The primary endpoint of this study was: quantitative improvements using the Clinician Administered PTSD Scale (CAPS-5). Using this scale, "Response" was defined as a reduction of 6 or more points. "Remission" was defined as Response plus no longer meeting clinical symptom criteria and having a severity score

SUMMARY OF CLINICAL TESTING
Palo Alto Health Sciences Inc. performed a prospective, single arm, un-blinded investigation of Freespira in the indicated population. Patients with a primary diagnosis of PTSD (military and non-military, combat and non-combat) were enrolled into a four-week Freespira program. At enrollment, and then at specified intervals, patients underwent assessment using validated questionnaires (PHQ-9, SF-36, PDSS, CGC-S and CAPS-5 30-day score). In addition, every time a patient used Freespira, their EtCO2 and RR data were stored locally (on the tablet) and securely uploaded to a cloud server for clinician review.
The primary endpoint of this study was: quantitative improvements using the Clinician Administered PTSD Scale (CAPS-5). Using this scale, "Response" was defined as a reduction of 6 or more points. "Remission" was defined as Response plus no longer meeting clinical symptom criteria and having a severity score =6 pts

Response Rates with increasing Thresholds of Response Definition
*% change from mean baseline score of 52.0
The following adverse events were reported as possibly related to the treatment: chest pain, cold symptoms, and headache.
Patient satisfaction with Freespira was high post-treatment (84%), at 2-months (74%), and 6-months (90%) post-treatment. These percentages were based on the number of patients who gave a score of 3 or 4 on a 0-4 scale (where "0" meant "not satisfied" and "4″ meant "very satisfied") at each time point.
The clinical data demonstrate that Freespira provides a safe and effective, adjunct at-home treatment for the symptoms associated with PTSD that can be easily and widely disseminated. Freespira is completed in 4-weeks at-home without unpleasant side-effects. This likely contributed to the relatively low dropout rate (20%), high protocol adherence (77%), and high satisfaction scores (84%).
EQUIVALENČE TO PREDIČATE DEVIČE
Freespira is substantially equivalent to the predicate device based on the information summarized here:
The subject device has the same design and dimensions, and uses identical materials as the device cleared in K131586. The subject device has the same technological characteristics to the device cleared in K131586 except that the device can now also be used while it is plugged into the AC power adaptor. The fundamental difference between the two devices is that the subject device has expanded indications that include its use as an adjunct treatment for symptoms associated with PTSD. The subject device has undergone bench and clinical testing to ensure the device is as safe and effective as the predicate.

510(k) Summary
CONCLUSION
Based on the testing performed, namely a prospective clinical study, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate device. The similar technological characteristics and performance characteristics for the proposed Freespira are assessed to be substantially equivalent to the predicate device. The device is considered safe and effective for its intended use.
