Central venous pulsations associated with a falsely low oxygen saturation measured by pulse oximetry

Abstract

Venous pulsations are thought, but to our knowledge have never been demonstrated, to result in underestimation of oxygen saturation measured by pulse oximetry (SpO2); however, to our knowledge, this has never been demonstrated. A patient with ischemic cardiomyopathy requiring intra-aortic balloon counterpulsation (IABC) had to withstand a temporary cessation of IABC (period I), during which she had marked central venous pulsations and a pulse oximeter bias of -18%. After IABC was reinstituted (period II), the venous pulsations disappeared and the bias was reduced to 0%. Cardiac output, systemic vascular resistance, and temperature during both periods were comparable. Pulmonary vascular resistance, however, was much lower during period II. We postulate that the bias was caused by venous pulsations significantly contributing to the AC, or variable component, of light absorption.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Pulse oximetry values were both lower in cases where CVP contributed to the signal.

    “The pulse oximetry values were both lower in cases where CVP contributed to the signal.”
  • Shelley et al. and Sami et al. both demonstrated the influence of the venous signal on SpO2, showing that forehead and earlobe pulse oximeters produced a significantly biased variable component of the PPG determined to originate from central venous pressure (CVP).

    “Shelley et al. and Sami et al. both demonstrated the influence of the venous signal on SpO2, showing that forehead and earlobe pulse oximeters (respectively) produced a significantly biased variable component of the PPG determined to originate from central venous pressure (CVP) [125,127].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
