Fig. 1 Patient selection, 2001–2011. Flowchart showing the patient selection process. COPD, chronic obstructive pulmonary disease; EMS, emergency medical services. Resuscitation 2016 104, 76-82DOI: (10.1016/j.resuscitation.2016.04.017) Copyright © 2016 Elsevier Ireland Ltd Terms and Conditions
Fig. 2 Bystander CPR and survival upon hospital arrival following OHCA in relation to COPD-status from 2001 to 2011. Temporal trends in bystander CPR and patients alive upon hospital arrival following OHCA in relation to COPD-status. Changes over time were tested, a two-sided p-value of <0.05 was considered statistically significant. COPD, chronic obstructive pulmonary disease; CPR, cardiopulmonary resuscitation; OHCA, out-of-hospital cardiac arrest.

Fig. 3 Long-term survival following OHCA in relation to COPD-status from 2001 to 2011. Temporal trends in patients alive at day 30 and year 1 following OHCA in relation to COPD-status. Changes over time were tested, a two-sided p-value of <0.05 was considered statistically significant. COPD, chronic obstructive pulmonary disease; OHCA, out-of-hospital cardiac arrest.

Fig. 4 Logistic regression analyses of association between COPD-status and survival upon hospital arrival following OHCA. Odds ratios for survival upon hospital arrival after OHCA in COPD patients compared to non-COPD patients when adjusting for possible confounders. Odds ratio <1.00 indicates that COPD patients are negatively associated with survival upon hospital arrival. AED, automated external defibrillator; COPD, chronic obstructive pulmonary disease; CPR, cardiopulmonary resuscitation; OHCA, out-of-hospital cardiac arrest; OR, odds ratio.

Fig. 5 Logistic regression analyses of association between COPD-status and 30-day survival following OHCA. Odds ratios for 30-day survival after OHCA in COPD patients compared to non-COPD patients when adjusting for possible confounders. Odds ratio <1.00 indicates that COPD patients are negatively associated with 30-day survival. AED, automated external defibrillator; COPD, chronic obstructive pulmonary disease; CPR, cardiopulmonary resuscitation; OHCA, out-of-hospital cardiac arrest; OR, odds ratio.
