The ideal flow rate for patients with COPD intends to increase the levels of arterial partial pressure of oxygen (PaO2) to between 60 to 65 mm Hg, saturating the blood with 90 percent to 92 percent oxygen, according to WebMD. It has been shown that higher flow rates than this are not beneficial and can even pose risks for the patient. As with most medical treatments, there are both long-term and short-term benefits, as well as risks involved with using oxygen for patients with COPD.
