Automated oxygen titration, weaning and monitoring (FreeO2) allows oxygen management in spontaneously breathing patients receiving oxygen with nasal cannula, oxygen mask, nasal high flow, CPAP or NIV. Liberal oxygen therapy has been shown to increase mortality. Recent meta-analyses and guidelines underline the necessity to accurately titrate oxygen to avoid both hypoxemia and hyperoxemia. Studies conducted in hypoxemic (pneumonia, COVID-19, adult or pediatric patients) or hypercapnic patients (acute exacerbations of COPD) demonstrated that in comparison with manual titration, FreeO2 increased the time in the oxygenation target, reduced the episodes of hypoxemia and hyperoxemia, and decreased the duration of oxygen therapy and hospital length of stay. In addition, a continuous and remote monitoring of cardio-respiratory parameters and new scores (EWS.O2 Early Warning Score-O2) is possible to detect early worsening of patients’ clinical condition. Remote monitoring at home is a new strategy evaluated in patients with COPD exacerbation with this device (FreeDom strategy).
