Longitudinal Trend Tracking

Evaluates the device's ability to consistently track respiratory changes over time.

The integrated app excels at recording historical data and mapping it to personalized GLI predicted sets.

The app stores both spirometry and oximetry data alongside symptom logs, creating a highly detailed, chronological health diary.

Longitudinal Trend Tracking

Evaluates the device's ability to consistently track respiratory changes over time.

Clinical Spirometry Correlation

Assesses how closely the home measurements align with formal clinical pulmonary function tests.

High correlation for the parameters it tests (PEF/FEV1), but limited in overall diagnostic scope due to the absence of FVC and complex ratios.

Dual tracking of oxygen saturation and full-loop spirometry heavily aligns with the protocols used in formal pulmonary function labs.

× Reusable turbine must be cleaned meticulously to maintain accuracy.

Expert Review Summary

Our clinical assessment and verdict for each device

MIR Smart One

Recommended

"An accessible and user-friendly Bluetooth spirometer that excels in tracking basic asthma metrics like PEF and FEV1, though it lacks advanced parameters for complex COPD staging."

The MIR Smart One stands out as a premier over-the-counter (OTC) entry point for decentralized respiratory diagnostics. Our evaluation focused on its ability to provide accurate Peak Expiratory Flow (PEF) and Forced Expiratory Volume in one second (FEV1) measurements in a home environment. Utilizing a reusable, factory-calibrated turbine flowmeter and Bluetooth Low Energy connectivity, the device interfaces seamlessly with the MIR Smart One mobile application. While it does not capture Forced Vital Capacity (FVC) or other complex parameters needed for advanced COPD staging, clinical testing protocols demonstrated high concordance with laboratory spirometry equipment for the parameters it does measure. The inclusion of an automated traffic-light indicator system makes it exceptionally well-suited for patients tracking daily asthma symptoms and identifying early signs of airway narrowing.

MIR Spirobank Oxi

Highly Recommended

"A highly versatile, 2-in-1 smart device that seamlessly merges comprehensive clinical spirometry with reflectance pulse oximetry for complete home respiratory management."

The MIR Spirobank Oxi elevates remote patient monitoring by integrating two vital diagnostic tools into a single, highly portable device. Not only does it deliver full Flow/Volume loop spirometry (measuring FVC, FEV1, PEF, FEF2575, and more) using MIR's proven turbine technology, but it also features an innovative touch reflectance pulse oximeter to measure SpO2 and heart rate. FDA-cleared and compliant with ATS/ERS 2019 standards, the device connects via Bluetooth 5.0 to the MIR Spirobank mobile app. This allows users to view real-time plethysmographic curves, track longitudinal trends, log symptoms, and generate comprehensive PDF reports for their healthcare providers. It is an exceptionally powerful tool for managing complex respiratory conditions where both airway obstruction and oxygen saturation are critical metrics.
