Brief Summary

O2matic HOT is a further development of O2matic and is intended for home oxygen use with patients in need of long-term oxygen treatment (LTOT). O2matic HOT is a closed-loop system which on basis of signals from pulse oximetry titrates the oxygen flow to the patient. In this crossover trial patients are admitted for 24 hours twice. Once with usual fixed dose oxygen and once with oxygen titration by O2matic HOT.
