Abstract

BACKGROUND

The level of arterial carbon dioxide partial tension (PaCO2) is a sine qua non for the determination of the adequacy of ventilation. The aim of this study was to assess the usefulness of SenTec Digital Monitor System in measuring transcutaneous arterial carbon dioxide partial tension (PCO2) non-invasively for the management of chronic respiratory failure.

METHODS

Three ICU patients suffering from chronic respiratory failure were enrolled. We recorded the data of PCO2 measured by a transcutaneous ear sensor (V-Sign : SenTec Inc.) and the data of PaCO2 (GASTAT-603ie Techno Medica Co., Ltd., Japan) obtained from arterial blood gas analysis.

RESULTS

The mean PCO2 was 67.2 mmHg (min. 65.9 mmHg, max. 80.2 mmHg, n = 10), and the mean PaCO2 was 71.2 mmHg (min. 67.2 mmHg, max. 79.0 mmHg, n = 10). Regression analysis showed good correlation between PCO2 and PaCO2 (PCO2 = .95 x PaCO2-0.18 mmHg; R = 0.74). Bland-Altman analysis of PCO2 yields a bias of d = 3.9 mmHg with limits of agreement (1SD) -0.4 mmHg, +8.2 mmHg.

CONCLUSIONS

SenTec Digital Monitor System enables non-invasive and reliable trend monitoring of PCO2 levels in patients with chronic respiratory failure.

摘要

背景

动脉血二氧化碳分压（PaCO2）水平是确定通气是否充分的必要条件。本研究的目的是评估SenTec数字监测系统在无创测量慢性呼吸衰竭患者经皮动脉血二氧化碳分压（PCO2）以用于管理中的实用性。

方法

纳入3例患有慢性呼吸衰竭的ICU患者。我们记录了经皮耳部传感器（V-Sign：SenTec公司）测量的PCO2数据以及从动脉血气分析获得的PaCO2数据（GASTAT-603ie，日本Techno Medica公司）。

结果

平均PCO2为67.2 mmHg（最小值65.9 mmHg，最大值80.2 mmHg，n = 10），平均PaCO2为71.2 mmHg（最小值67.2 mmHg，最大值79.0 mmHg，n = 10）。回归分析显示PCO2与PaCO2之间具有良好的相关性（PCO2 = 0.95×PaCO2 - 0.18 mmHg；R = 0.74）。PCO2的Bland-Altman分析得出偏差d = 3.9 mmHg，一致性界限（1SD）为-0.4 mmHg，+8.2 mmHg。
