A transcutaneous oxygen sensor was used continuously during surgical management of a ruptured abdominal aortic aneurysm. Closed chest compression initiated for intraoperative cardiac arrest gave an inadequate cardiac output on the basis of falling PtcO2 despite transmitted femoral pulses and an excellent PaO2. This discordance provided a rationale for open cardiac massage, which increased the cardiac output and tissue perfusion (PtcO2) needed for successful resuscitation. The PtcO2 sensor provides immediate, non-invasive, and continuous information regarding tissue oxygenation. It reflects the PaO2 in hemodynamically stable patients as well as providing a sensitive indicator for inadequate cardiac output during shock. In patients undergoing cardiopulmonary resuscitation, a falling PtcO2 with an acceptable PaO2 indicates poor tissue perfusion and, in select circumstances, may warrant open cardiac massage.
在腹主动脉瘤破裂的手术治疗过程中持续使用经皮氧传感器。尽管有股动脉搏动且动脉血氧分压（PaO2）良好，但因术中心脏骤停而启动的闭胸按压，基于经皮氧分压（PtcO2）下降，心输出量不足。这种不一致为开胸心脏按压提供了理论依据，开胸心脏按压增加了成功复苏所需的心输出量和组织灌注（PtcO2）。PtcO2传感器可提供有关组织氧合的即时、非侵入性和连续信息。它在血流动力学稳定的患者中反映PaO2，同时也为休克期间心输出量不足提供敏感指标。在进行心肺复苏的患者中，PtcO2下降而PaO2可接受表明组织灌注不良，在某些情况下，可能需要进行开胸心脏按压。
