A system of transtracheal oxygen administration has been developed which is more effective for rehabilitating chronic obstructive pulmonary disease (COPD) patients than traditional systems for providing continuous oxygen therapy. The procedure involves administering oxygen continuously through a No. 16 intravenous catheter inserted transtracheally. Therapeutic PaO2 levels are attained with an oxygen flow of 0.25 to 1 liter per minute. Transtracheal oxygen administration has numerous advantages over nasal cannula or Venturi mask devices. With this system, the patient requires 3 to 4 times less oxygen; therefore, a 2.7-kg (6-lb) portable tank will last most of one day. Oxygen-enriched air via transtracheal catheter reaches the lungs directly with less respiratory effort. Delivery of oxygen is not impaired by sinusitis, mouth-breathing, displacement of nasal cannula or loss of oxygen into the room. Patients experience an immediate sensation of being able to breathe more easily, begin ambulating the day of the procedure, have improved nutrition and return to many normal activities.
一种经气管给氧系统已被研发出来,对于慢性阻塞性肺疾病(COPD)患者的康复而言,该系统比提供持续氧疗的传统系统更有效。该 procedure 包括通过经气管插入的16号静脉导管持续给氧。通过每分钟0.25至1升的氧流量可达到治疗性的动脉血氧分压(PaO2)水平。与鼻导管或文丘里面罩装置相比,经气管给氧有许多优点。使用该系统时,患者所需氧气量减少3至4倍;因此,一个2.7千克(6磅)的便携式储氧罐可持续使用大半天。经气管导管输送的富氧空气可直接到达肺部,呼吸用力更小。氧气输送不会因鼻窦炎、张口呼吸、鼻导管移位或氧气泄漏到室内而受到影响。患者会立即感觉到呼吸更轻松,在手术当天即可开始走动,营养状况得到改善,并能恢复许多正常活动。
