高压氧舱安全无阻力吸氧装置的临床实用性研究

Safe Oxygen Inhaling Device Without Resistance in Hyperbric Oxygen Chamber

【目的】通过测定新吸氧装置吸氧阻力和舱内氧浓度值,探讨新吸氧装置的高压氧治疗临床实用性。【方法】分三组分别测量肺式供氧吸氧装置(A组)、连续供氧装置(B组)、新吸氧装置(C组)的吸氧阻力及舱内氧浓度值,并进行比较判定。【结果】B组舱内氧浓度值明显高于A、C两组,均有统计学意义(P<0.01),而A、C两组比较差异无统计学意义(P>0.05);A组吸气阻力值明显高于B、C两组,差异均有统计学意义(P<0.01),而B、C两组比较差异无统计学意义(P>0.05)。【结论】新吸氧装置既能减小吸氧阻力,又能将降低舱内的氧浓度,既有利于患者的高压氧治疗;又保证了高压氧治疗的安全性,这一新吸氧装置值得在临床上进一步推广。

[Objective]To evaluate the clinical value of a new oxygen inhaling device by observing the oxygen inhaling resistance and oxygen concentration in chamber. [Methods] Three groups included group A （pulmonary oxygen supply apparatus）, group B （continuous oxygen supply apparatus） and group C （new oxygen inhaling apparatus）. Oxygen inhaling resistance and oxygen concentration in chambers of three groups were measured. [Results] Oxygen concentration in chamber in group B was higher than that in group A and C, and there was statistical significance（ P 〈0. 01）, but there was no statistical significance between group A and group C（ P 〉0.05）. Oxygen inhaling resistance in group A was obviously higher than that in group B and C （P〈0. 01） , and there was statistical significance（ P 〈0. 01） , but no statistical significance was found between group B and C（ P 〉0.05）. [Conclusion]New oxygen inhaling device can diminish oxygen inhaling resistance and cut down oxygen concentration in chamber. The device is in favor of the treatment and safety of hyperbaric oxygen, so it is worthy of further clinical generalization. hyperbaric
