Figure 5From: Pupillary reflex measurement predicts insufficient analgesia before endotracheal suctioning in critically ill patientsCardiac rate (A), respiratory rate (B), mean arterial pressure (C), number of patients with insufficient analgesia (D, E) after 10, 20 or 40 mA tetanic stimulation in 34 critically ill patients. Insufficient analgesia was defined by an increase ≥1 point on the Behavioral Pain Scale (D) or on the Richmond Agitation Sedation Scale (E).Back to article page
