[Different approaches to long-term O2 therapy (LTOT) in patients using intermittent positive pressure ventilation]
Background:
Until now there is no conclusion about a distinguished long-term O2 therapy in patients using IPPV.
Patients And Methods:
24 patients (6 women, 18 men, mean age 60 years, mean length of IPPV 15.6 months, mean length of long-term O2 therapy 16.7 months) with IPPV and long-term O2 therapy were studied by the topical and the past dose and the length of long-term O2 therapy.
Results:
1. Thirteen patients had the highest need for oxygen under strain with same need under IPPV and daytime. 2. The distribution among the others was different, 3 patients showed an elevated need for oxygen from IPPV to day-time to activity, 3 needed oxygen only under strain. 3. Changing the length was necessary in 4 patients. 4. The individual dose was changed in the course in 18 patients, reduced in 4, raised in 6 and both in 8 patients.
Conclusion:
1. A distinguished long-term O2 therapy with testing the need in rest, under IPPV and in activity is convenient. 2. Regular controls are necessary because of the individual changings.
