Influence of the Coronavirus Disease 2019 Pandemic and Bystander-victim Relationship on the Willingness of Laypeople and Health-care Providers to Perform Cardiopulmonary Resuscitation.

Participants were less W-CPR during the COVID-19 pandemic on all recipients (laypeople: 2.8%-21.0%, HCPs: 7.6%-31.2%), except for laypeople with FMs. The recipient's relationship was more critical in W-C-CPR than in W-CO-CPR, especially in HCPs.
