Hey Vince,
The important words in the scenario are “effective” and “disaster”. In a MCI, many liberties are granted by protocol to allow for rapid triaging and care. In many cases the low priority patients (walking wounded) are perfect candidates for treatment by citizens with first aid training. The severely injured (the dead or dying), unfortunately, due to the degree of care that must be siphoned from rescue resources are provided “comfort care”. It is generally, the group in the middle, significant injuries, that are borderline life threatening, that are candidates for more formal EMS care and transport.
