A Study of the Impact of CVS-ICU Cardiac Arrest Efficiency Initiative on the Delay from Cardiac Arrest to Critical Resuscitation Efforts


About this study

The primary aim of this study is to determine the impact of our CVS-ICU cardiac arrest efficiency initiative on the delay from cardiac arrest to critical resuscitation efforts.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

Inclusion Criteria:

  • All patients age 18 or older with Mayo Research Authorization on file who develop cardiac arrest in the CVS-ICU within 10 days of chest closure

Exclusion Criteria: 

  • Prisoners 
  • Adults lacking capacity
  • Children (<18 years old) 
  • Patients who are “Do Not Resuscitate” (DNR) and patients with a known pregnancy
  • Cases of cardiac arrest will be retrospectively reviewed to exclude patients who developed cardiac arrest for which the CALS-S algorithm would not have been appropriate (e.g., primary respiratory failure, septic shock)
