TY - JOUR T1 - Life's a gas: saturation should not be used for prescription of long-term oxygen therapy JF - ERJ Open Research JO - erjor DO - 10.1183/23120541.00495-2021 VL - 7 IS - 4 SP - 00495-2021 AU - Magnus Ekström Y1 - 2021/10/01 UR - http://openres.ersjournals.com/content/7/4/00495-2021.abstract N2 - Hypoxaemia is a potential threat to all aerobic organisms, including humans. Long-term oxygen therapy (LTOT) given to people with chronic, severe hypoxaemia was the first intervention in COPD shown to prolong life [1, 2].Transcutaneous oxygen saturation by pulse oximetry is unreliable for evaluating severe hypoxaemia or need for long-term oxygen therapy https://bit.ly/3CPZXOS ER -
