Automatic oxygen supply with the O2matic device has been shown to provided an enhanced oxygen treatment in patients with hypoxemia. O2matic was significantly better than manual control to maintain oxygen saturation within target interval and to reduce time with unintended hypoxemia in patients suffering from chronic obstructive pulmonary disease. This trial investigates the effect of using O2matic in hypoxic patients submitted to the Department of Cardiology.
Oxygen supply to patients with cardiovascular disease has been subject to several investigations. Both too much and too little oxygen is supposed to be harmful. The O2matic device is a new way of supplying oxygen treatment which is significantly better than manual control to maintain oxygen saturation within target interval and to reduce time with unintended hypoxemia. The device has past favorable tests in patients suffering from chronic obstructive pulmonary disease. This study investigates the application of the O2matic device on hypoxic patients admitted to the Cardiology ward.

Time in designated saturation interval
We have predefined an optimum saturation interval of 92-96% with a target of 93%
Time frame: 24 hours of treatment
Time with hypoxemia
Time with saturation below 92% but above 85%
Time frame: 24 hours of treatment
Time with severe hypoxemia
Time with saturation below 85%
Time frame: 24 hours of treatment
Time with hyperoxemia
Time with saturation above 96%
Time frame: 24 hours of treatment
