To evaluate a monitor of pulmonary gas exchange (Deltatrac, Datex) in a clinical setting.
After in vitro evaluation, comparison over 2 min between VO2 and VCO2 values measured by the Deltatrac and the Douglas bag technique. Comparisons were also achieved over 8 h periods between the Deltatrac and a system using a mass-spectrometer.
Polyvalent intensive care unit (ICU 15 beds) in a 1200 bed general hospital.
Comparison with the Douglas bag technique in 10 patients undergoing controlled ventilation. Comparison with the mass-spectrometer system in 25 other patients undergoing controlled or pressure support ventilation.
Compared to the results obtained by the Douglas bag technique, the bias (+/- 2 SD) for VO2 and VCO2 was -3.5 +/- 26.6 and 6.1 +/- 12.7 ml.min-1, respectively. By comparison with the mass-spectrometer system, the bias for VO2 and RQ was -5.8 +/- 16.0 ml.min-1 and 0.018 +/- 0.048, respectively. No drift between the two systems was observed over time.
The Deltatrac appears suitable for VO2 and VCO2 measurements in ventilated patients and equivalent to a mass-spectrometer system for long term measurements.
在临床环境中评估一种肺气体交换监测仪（Deltatrac，Datex公司）。
在体外评估后，比较Deltatrac测量的VO₂和VCO₂值与道格拉斯袋技术在2分钟内测量的值。还比较了Deltatrac与使用质谱仪的系统在8小时期间的测量结果。
一家拥有1200张床位的综合医院的多科重症监护病房（ICU，15张床位）。
与10名接受控制通气的患者的道格拉斯袋技术进行比较。与另外25名接受控制通气或压力支持通气的患者的质谱仪系统进行比较。
与道格拉斯袋技术获得的结果相比，VO₂和VCO₂的偏差（±2SD）分别为-3.5±26.6和6.1±12.7 ml·min⁻¹。与质谱仪系统相比，VO₂和呼吸商（RQ）的偏差分别为-5.8±16.0 ml·min⁻¹和0.018±0.048。随着时间的推移，未观察到两个系统之间有漂移。
Deltatrac似乎适用于测量通气患者的VO₂和VCO₂，并且在长期测量方面等同于质谱仪系统。
