The FreeO2 device automatically adjusts the oxygen flow rate thereby maintaining an ideal oxygen target for maximum patient safety throughout the treatment period, while reducing potential side effects.
How it works FreeO2 controls a closed loop system that continuously adjusts the oxygen flow between 0 and 20 L/min in real time, (with or without a humidification system) based on the blood’s oxygen saturation (SpO 2).
The FreeO2 tailors oxygen therapy treatment to the patient’s needs, thereby reducing the risk of serious complications related to hypoxemia, including both hypoxia and hyperoxia. Clinical recommendations can be delivered without complications for both the patient, and the attending personnel.

Medico-economic benefits
FreeO2 was designed and developed by clinicians aware of both the common and serious dangers of oxygen toxicity, and the inherent difficulties encountered by healthcare workers. Safety and testing FreeO2 has been the subject of numerous successful studies and clinical validation trials on more than 500 patients in Canada and Europe.

FreeO2
The primary goal of oxygen therapy is to prevent hypoxia and hyperoxia.
The first goal: avoid hypoxia When SpO2 is less than 88%, tachycardia, myocardial ischemia, and arrhythmia events can occur. For COPD patients, this increases pulmonary artery pressure and the subsequent death rate from associated complications.
The second goal: avoid hyperoxia
