Abstract

BACKGROUND

In critically ill patients, clinicians can have difficulty obtaining accurate oximetry measurements.

OBJECTIVE

To compare the accuracy of nasal alar and forehead sensor measurements and incidence of pressure injury.

METHODS

43 patients had forehead and nasal alar sensors applied. Arterial samples were obtained at 0, 24, and 120 hours. Oxygen saturations measured by co-oximetry were compared to sensor values. Skin was assessed every 8 hours.

RESULTS

Oxygen saturations ranged from 69.8%-97.8%, with 18% of measures < 90%. Measurements were within 3% of co-oximetry values for 54% of nasal alar compared to 35% of forehead measurements. Measurement failures occurred in 6% for nasal alar and 22% for forehead. Three patients developed a pressure injury with the nasal alar sensor and 13 patients developed a pressure injury with the forehead sensor (χ2 = 7.68; p = .006).

CONCLUSIONS

In this group of patients with decreased perfusion, nasal alar sensors provided a potential alternative for continuous monitoring of oxygen saturation.

摘要

背景

在危重症患者中，临床医生可能难以获得准确的血氧测量值。

目的

比较鼻翼和前额传感器测量值的准确性以及压力性损伤的发生率。

方法

43 例患者同时应用前额和鼻翼传感器。在 0、24 和 120 小时采集动脉样本。将比色法测量的氧饱和度与传感器值进行比较。每 8 小时评估皮肤情况。

结果

氧饱和度范围为 69.8%-97.8%，18%的测量值<90%。与前额测量值的 35%相比，鼻翼测量值有 54%在比色法测量值的 3%以内。鼻翼传感器的测量失败率为 6%，前额传感器为 22%。3 例患者鼻翼传感器处发生压力性损伤，13 例患者前额传感器处发生压力性损伤（χ2=7.68；p=0.006）。
