The efficacy of the pulse oximeter was evaluated in lieu of multiple arterial blood gas (ABG) determinations as a screening method for the early diagnosis of hypoxemia and clinical fat embolism syndrome. A prospective analysis was performed on 43 patients with long bone and pelvic fractures without any associated chest wall, head, or intraabdominal trauma. A standard pulse oximetry reading was obtained initially within 12 hours of injury and at 24-hour intervals thereafter until the patient had been observed for 72 hours. Fifteen patients were hypoxemic with an oxygen-hemoglobin (O2-Hb) saturation less than or equal to 94%. All hypoxemic patients were evaluated by ABG measurements that demonstrated the expected correlation with the pulse oximetry readings. These patients were subsequently managed with an intensive pulmonary care regimen. Hypoxemia resolved in all patients within 48 hours of the initiation of treatment. The pulse oximeter is an efficient and reliable screening device to identify patients with clinically unrecognized hypoxemia.
作为低氧血症和临床脂肪栓塞综合征早期诊断的筛查方法，对脉搏血氧仪的有效性进行了评估，以替代多次动脉血气（ABG）测定。对43例无任何相关胸壁、头部或腹部创伤的长骨和骨盆骨折患者进行了前瞻性分析。在受伤后12小时内及之后每24小时进行一次标准脉搏血氧测定读数，直至对患者观察72小时。15例患者存在低氧血症，氧合血红蛋白（O2-Hb）饱和度小于或等于94%。所有低氧血症患者均通过ABG测量进行评估，结果显示与脉搏血氧测定读数具有预期的相关性。这些患者随后接受了强化肺部护理方案治疗。所有患者在开始治疗后48小时内低氧血症均得到缓解。脉搏血氧仪是一种有效且可靠的筛查设备，可用于识别临床上未被识别的低氧血症患者。
