In seventeen years, I’ve had to use a ring-cutter only one time in the prehospital setting, because I had other tasks to attend to on that particular patient, and the swelling had reached the point of causing neuromuscular compromise of the digit. In the field we often have fast access to the patient before swelling has reached the point that hinders simply being able to twist the ring off.
If you find a patient beyond that point, and have time to dedicate to the task, here is a trick to remove a ring using a strap from an oxygen mask. We’ve not been able to use it yet, but it looks like a great idea.
