Breathing is something most people only notice when it becomes difficult. Blood oxygen levels can shift without obvious symptoms, and peak expiratory flow¡ªthe speed and force of each exhale¡ªcan decline gradually over days or weeks before the change becomes obvious. For people managing asthma, COPD, or any condition affecting the respiratory system, a consistent home reading routine makes those shifts easier to catch and discuss with a clinician. The Lung & Oxygen Kit combines pulse oximetry, peak flow monitoring, and blood pressure readings into one organized home routine. Whether you're checking SpO2 after activity, tracking peak flow as part of an asthma action plan, or keeping blood pressure records alongside respiratory health, the Kit keeps all three readings in one place¡ªorganized, connected, and easier to share.
