How To Carry Out Home Oxygen Therapy Scientifically 2?
3. The method of oxygen therapy
Under the guidance of a doctor, choose a suitable oxygen concentrator for home oxygen therapy.
Three elements of oxygen therapy: flow rate/wearing time/oxygen therapy course
Long-term (long-term) home oxygen therapy (LTOT): refers to the inhalation of low-concentration oxygen for
more than 15 hours a day and night, and lasts for a long time (go to the hospital after 60-90 days to re-evaluate
whether to continue long-term oxygen therapy), so that PaO2≥mmHg or SaO2 An oxygen therapy method
that rises to 90%. The concentration is 24%-28%, and the oxygen flow rate is generally 1-2L/min.
Refining: low-flow oxygen inhalation (1-2 liters) / more than 15 hours a day / 6 months as a course of treatment
4. Detection of the effect of oxygen therapy
What effect should be achieved after oxygen therapy? Are there quantitative detection indicators? Physical condition observation and quantitative data detection:
1 Observation of physical condition
Cardiovascular system response: After oxygen therapy, the patient's expression changes from indifference or agitation
to quietness, clarity of mind, slow heart rate, improvement of peripheral circulatory system (lips/nails/fingers, etc.),
rosy, dry, warm and purple skin The phenomenon disappeared, indicating that the effect of oxygen therapy was good.
Respiratory system response: After oxygen therapy, dyspnea/shortness of breath improved, respiratory movement was stable,
respiratory frequency slowed down, and work of breathing decreased, showing that the effect of oxygen therapy was good.
2 Quantitative data detection:
Transcutaneous oxygen saturation monitoring (SpO2)
A blood oxygen value above 90% is normal blood oxygen. Note that lung diseases are accompanied by symptoms
of carbon dioxide retention. When oxygen is only inhaled, the blood oxygen normal range is 95% to 98%.
