They have, however, expressed some concerns that we would like to address. They argue that extracorporeal cardiopulmonary resuscitation (E-CPR) should be performed irrespective of COVID-19 status, resuscitation provider safety, emotional or physical stress, and resource availability 2 ; however, we emphasize these risks. We believe that resuscitation provider safety, emotional or physical stress, and resource availability, are very important factors, and could be key determinants in deciding whether to perform E-CPR. It is clear that the highest priority should be the prevention of infection in healthcare workers, and we believe that E-CPR should be discouraged if there is any risk of infection by performing E-CPR. They point out that actual confirmed COVID-19 cases may well represent a small fraction of the number of originally suspected cases; however, the source that they have cited 3 also mentions that healthcare professionals underestimating the risk of transmission may spread the virus J o u r n a l P r e -p r o o f 4 to the rest of their team, and within the larger community, putting further strain on the healthcare system. Patient safety during E-CPR is an important issue. Stress during cardiopulmonary resuscitation (CPR) has been shown to be associated with worse CPR performance 4, 5 . Stress reduces focus and, therefore, in stressful situations, the ability to dismiss irrelevant information is reduced, leading to an increase in distractibility. Additionally, stress impairs rational decision-making, and is associated with a loss of team perspective and poor team performance. Stress-induced poor performance can further increase the mental stress of the rescuer, which could lead to a vicious cycle.
