Duus CL, et al. - Researchers performed this study on patients who underwent major abdominal cancer surgery and were continuously monitored with peripheral arterial oxygen saturation (SpO₂), heart rate (HR), and respiratory rate (RR) the first 4 days after surgery, to compare continuous monitoring to standardized Early Warning Score (EWS) with respect to the number of micro events detected. They used Fisher's exact test and Wilcoxon rank sum test to analyze the number and duration of events. Post-operative patients commonly had very low SpO₂ and tachycardia; these micro events were under-diagnosed by the EWS. By detecting these micro events, continuous monitoring can potentially contribute to earlier detection and, potentially, result in prevention of clinical complications.
