Table 3 Ability of the oscillometric monitor in detecting systolic or mean invasive pressure lower than 80 or 60 mmHg

From: Prospective clinical study to evaluate an oscillometric blood pressure monitor in pet rabbits

  Sensitivity Specificity Positive predictive value Negative predictive value
Systolic arterial blood pressure
 Cutoff of 80 mmHg for NIBP 46.3% (37.3%–5.56%) 77.6% (63.4%–88.2%) 83.8% (72.9%–91.6%) 36.5% (27.3%–46.6%)
 Cutoff of 90 mmHg for NIBP 74.0% (65.3%–81.5%) 57.1% (42.2%–71.2%) 81.3% (72.8%–88.0%) 46.7% (33.7%–60.0%)
Mean arterial blood pressure
 Cutoff 60 of mmHg for NIBP 73.8% (63.0%–82.8%) 78.4% (68.4%–86.5%) 76.5% (65.8%–85.3%) 75.8% (65.7%–84.2%)
 Cutoff 65 of mmHg for NIBP 91.8% (83.6%–96.6%) 61.4% (50.4%–71.6%) 69.4% (59.9%–77.8%) 88.5% (77.8%–95.3%)
  1. Specificity, sensitivity, positive and negative predictive value of the non-invasive oscillometric blood pressure (NIBP) device in detecting a systolic and a mean invasive blood pressure lower than 80 mmHg and 60 mmHg at different cutoff limits. Data are expressed as percentage (95% confidential interval)
