|
Term
| this is more common in the lower limb where the fascia is thick. Deep arteries, nerves, and veins contained withing the deep fascia are pressed upon by swollen tissues (muscles) because the fascia does not stretch or expand, this pressure cuts off vital blood supply causing tissue death (surgical emergency) |

|
|
Term
| blood gas is drawn from the arteries so the needle should be more perpendicular to the arm, rather than parallel as would be normal for an IV (venous line) |
