Regional breakdown of responses by distributing society, number of potential participants, and number of responses.

| Association of Cardiac Anesthetists (UK) | 550 | ||||
| North America | Society of Cardiovascular Anesthesiologists | 4,145 | 334 | 8.1% | 10 |

| South America | Confederacion Latinoamericana de Sociedades de Anestesiología | 2,350 | 215 | 1.7% | 8 |
| Brazilian Society of Anesthesiology | 10,443 | ||||
| Africa | Cardiothoracic Anaesthesia Society of South Africa | 50 | 22 | 46.0% | 10 |
| Asia | Asian Society of Cardiothoracic Anesthesia | Unknown | 33 | Unknown | 10 |
| Middle East | Various | Unknown | 19 | Unknown | 12 |
As the survey did not specifically ask which distributing society was involved, it is not possible to attribute an individual response to a specific organization, only to the region the participant was from. It is important to note that the percentage response is difficult to interpret as it is difficult to obtain the true denominator. For example, in South America, distribution was through non-specialist anesthesia societies hence the large number of potential participants—many of whom will not have cardiothoracic practice.
