Prognostic impact of hypernatremia for septic shock patients in the intensive care unit

Figure 1 Flow chart of patients involved in this study. ICU: Intensive care unit; IAH: Intensive care unit-acquired hypernatremia.

Figure 2 The relationship of persistent inflammation, chronic critical illness and rapid recovery for patients with septic shock between intensive care unit-acquired hypernatremia group, hypernatremia at admission group and normonatremia group. A: Patients with persistent inflammation; B: Patients with chronic critical illness; C: Patients with rapid recovery. ICU: Intensive care unit; PICS: Persistent inflammation, immunosuppression and catabolism syndrome; CCI: Chronic critical illness; RR: Rapid recovery.
