Table 2 Advantages and disadvantages of interventions learned in initial laboratory use*
Intervention Advantages Disadvantages
Digital compression Fast, easiest to target, one-handed Smallest muscles tire fastest
Manual compression Heels of hands work quickly If two hands are used, no hand is free
Knee compression Powerful, sustained, no hands Clumsy, can obscure wound
Kettlebell Fast, rounded edges, frees one hand Heavy, tilts, one hand to steady
CRoC First available, best known device Disc can fall, has the most steps
SJT Fast, may use binder on pelvis Newest, least known device
JETT Harness may splint a pelvis fracture Disc can fall, two straps, two discs
AAT Targets pressure point broadly May block vena cava
