The Effect Of Oxygen Temperature On The Comfortableness And Curative Effect Of Patients With The Disease Of Respiratory System

Object: According to molecular heat principle, the humidity and activity of gas are linearrelation with the gas temperature, that is, the humidity and activity of gas go up with the raise ofthe gas temperature. The research is done in order to examine the effect of heated oxygen on thecomfortableness and treatment effect of patients with the disease of respiratory system whoaccept oxygen therapy, find the optimal temperature of oxygen therapy and provide referencebasis for oxygen therapy.Methods: Selecting 84 patients in respiratory division of General Hospital of Tianjin MedicalUniversity. 84 eligible patients with the disease of respiratory system were randomly assigned toeither the intervention group (n=42) or the control group (n=42). All patients completedquestionnaires of oxygen therapy at baseline assessment. Patients in the intervention group andthe control group received routine nursing care and took analgesic medicine as prescribed.Patients in the intervention group were treated by heated and humidified oxygen individuallywho used the MR850 heated humidification tool of Fisher & Paykel medical care limitedcompany in New-Zealand, 2 hours twice a day for three days. And patients in the control groupwere treated by ambient humidified oxygen individually 2 hours twice a day for three days. Afterthat, all patients were similarly reassessed.Results: (1) Before the intervention, all patients fill in the questionnaires. The comfortablenessand treatment effect of 42 patients in the intervention group were the same as those in the controlgroup at baseline assessment (P＞0.05), which is comparable. (2) When the two groups werereassessed after three days, there was statistical significance between the two groups in thefollowing aspects (P＜0.05): oxygen temperature, oxygen humidity, pharynx nasals' feeling, cough, expectoration difficulty, phlegm fluidity form and phlegm quantity. (3) There was nostatistical significance between the two groups in the aspects of oxygen smell, flow rate, feelingof lower respiratory tract, feeling of body, body temperature, arterial pulse, respiration and bloodpressure(P＞0.05). Heated oxygen therapy is more beneficial for comfortableness of patients withthe disease of respiratory system, which effect on oxygen temperature, humidity, pharynx nasals'feeling, cough, expectoration difficulty, phlegm fluidity form and phlegm quantity. But heatedoxygen therapy don't effect on oxygen smell, flow rate, feeling of lower respiratory tract, feelingof body, body temperature, arterial pulse, respiration and blood pressure.Conclusion: The oxygen temperature is the same as ambient temperature (20℃～22℃) inoxygen therapy, which is lower than the temperature of nasal cavity (30℃～35℃). The patientsfeel that inhaled gas is dry and cold. Oxygen temperature is 30℃～35℃in heated oxygentherapy, which gets closer to the temperature of nasal cavity. The humidity and activity of gas goup with the raise of the gas temperature. In order to avoid stimulus, heated oxygen inhaled into respiratory tract makes the patients comfortable and improves the effect of oxygen therapy.Heated oxygen therapy could improve on the comfortableness and treatment effect of patientswith the disease of respiratory system who accept oxygen therapy. Further research is stillneeded to examine the effectiveness of heated oxygen therapy on gas analysis in blood. Heatedoxygen therapy would be used in clinical in the future in order to make the patients comfortableand improve the effect of oxygen therapy.
