Pulse oximetry appears to improve quality of care by the early detection of hypoxia noninvasively. We tested the hypothesis that the widespread use of pulse oximetry over a 5-year period in the operating rooms at our institution had resulted in a reduction in blood gas measurements and in departmental operating costs. The total number of blood gas determinations per hour of anesthetic time at our institution decreased by 44%, from 7.64 to 4.26 measurements per 100 operating room hours. The number of capnography units in the operating rooms increased from 8 to 14, the number of pulse oximeters increased from 0 to 22, and oximeter use increased from 0 to 100% for all anesthetics. The total cost to provide oximetry, capnography, and blood gas measurements in 1989-1990 was less than the cost to provide blood gas measurements alone in 1985-1986. The introduction of these technologies was accomplished without an increase in cost: $76,880 in 1985-1986 versus $71,025 in 1989-1990.
脉搏血氧饱和度测定法似乎通过早期无创检测低氧血症来提高医疗质量。我们检验了这样一个假设：在我们机构的手术室中，5 年期间广泛使用脉搏血氧饱和度测定法导致了血气测量次数的减少以及科室运营成本的降低。我们机构每麻醉小时的血气测定总数下降了 44%，从每 100 个手术室小时 7.64 次测量降至 4.26 次。手术室中二氧化碳监测仪的数量从 8 台增加到 14 台，脉搏血氧仪的数量从 0 台增加到 22 台，并且所有麻醉中血氧仪的使用率从 0 增加到了 100%。1989 - 1990 年提供血氧测定、二氧化碳监测和血气测量的总成本低于 1985 - 1986 年单独提供血气测量的成本。这些技术的引入在成本未增加的情况下完成：1985 - 1986 年为 76,880 美元，而 1989 - 1990 年为 71,025 美元。
