From: The role of point-of-care ultrasound in the diagnosis of pericardial effusion: a single academic center retrospective study

  POCUS (n = 75) Departmental ECHO (n = 126) Mean difference p-valuea
Mean systolic blood pressure (mmHg) 112 (95% CI 107–117) 121 (95% CI 116–126) 8.3 (95% CI 1.2–15.5) 0.022
Mean diastolic blood pressure (mmHg) 73 (95% CI 69–77) 73 95% CI 70–76) 0.63 (95% CI − 3.6–4.9) 0.77
Mean heart rate (beats per minute) 99 (95% CI 94–104) 94 (95% CI 82–106) − 5.4 (95% CI − 11–0.3) 0.63
