Cardiopulmonary resuscitation duration and patient survival in a South Indian intensive care unit

Figure 1 Flow diagram of retrospective study on cardiopulmonary resuscitation and return of spontaneous circulation in intensive care unit patients. CPR: Cardiopulmonary resuscitation; DNR: Do-not-resuscitate; ROSC: Return of spontaneous circulation.

Figure 2 Initial cardiac rhythm distribution among study participants. Pie chart showing the proportion of patients with pulseless electrical activity (48.6%), asystole (35.2%), and ventricular fibrillation/tachycardia (16.2%) as initial recorded rhythms. VF: Ventricular fibrillation; VT: Ventricular tachycardia; PEA: Pulseless electrical activity.

Figure 3 Duration of cardiopulmonary resuscitation distribution. Box-and-whisker plot displaying the median cardiopulmonary resuscitation duration of 15 minutes (interquartile range: 10-22 minutes). CPR: Cardiopulmonary resuscitation; MICU: Medical intensive care unit.

Figure 4 Probability of return of spontaneous circulation by cardiopulmonary resuscitation duration. Kaplan-Meier curve demonstrating the declining probability of return of spontaneous circulation achievement with increasing duration of cardiopulmonary resuscitation (log-rank P < 0.001).

Figure 5 Survival outcomes. CPR: Cardiopulmonary resuscitation; DNR: Do-not-resuscitate; ROSC: Return of spontaneous circulation.

Figure 6 Forest plot of mortality predictors. Graphical representation of multivariate Cox regression results showing hazard ratios of mortality predictors. CPR: Cardiopulmonary resuscitation; ROSC: Return of spontaneous circulation.
