The Research On The Effects Of Oxygen Therapy In The Non-MV Clients After Tracheotomy Using Equipments HH And HME For Humidification And Heating

ObjectivesIn this study, two heated humidified equipments were used in severetraumatic brain injury tracheotomy non-mechanically ventilated patients withlong-term continuous oxygen therapy, the clinical effect of sputum,oxygentherapy,lung infections were observed.Compared the clinical effects of twoequipments,in order to find the evidences to support the long-term continuousoxygen therapy,and reduce the complications caused by the non-mechanicallyventilated patients in the clinical long-term oxygen therapy, improve the qualityof life.MethodsDivided the clients who meet the experimental request into HH group（n=105）and HME group（n=95） accordance with the hospital date randomly, Collectedgeneral information about the two groups of patients, and24hours urine,sputum properties, PaO₂, SaO₂, etc. HH group use HH for humidification andheating, and HME group use HME. Humidifying effects about sputum propertiesand average daily sputum volume, effects of oxygen therapy on PaO₂, SaO₂,incidence of pulmonary infection were compared between these two groups on24h、3d、5d、7d、10d、14d.ResultsThere was no different between the two groups on the clients’ generalinformation24hours urine, sputum properties, PaO₂, SaO₂and so on. On the7th days of heated humidified, the humidifying effects about sputum properties andaverage daily sputum volume, the infection rate on HH group were better than HMEgroup（P<0.05）, while there were significantly differences between two groups in thehumidifying effects on the14th days（P<0.01）.The effects on oxygen therapy aboutPaO₂,SaO₂is better in HH group than HME group（P<0.05）.ConclusionBoth of the two equipments can improve the humidifying effects, effects of oxygentherapy, incidence of pulmonary infection on the Non-MV clients who receivinglong-term continued oxygen therapy. There is no different between the two groupswhen the oxygen therapy time <7d. HH is better use for the clients after tracheotomywith severe brain trauma receiving long-term continued oxygen therapy（≥7d）.
