Q

steps of a modified allens test

A

1) have pt make a fist
2) obstruct both the radial and ulnar arteries by applying pressure with your thumb
3) have a patient open their hands and hand will turn white
4) release pressure from ulnar artery

  • hand should pink up in 1-2 seconds
  • if not collateral circulation isn’t good
  • use another site

Q

example of point of care testing

A

I stat

*done in 90 seconds

24
Q

if paco2 is in acceptable range what should your response be?

A

you should not put the patient on a ventilator or even change the vent settings

25
Q

if pt paco2 is greater than 45 what should you do?

A

initiate mechanical ventilation

*if pt is already own vent you need to help vent

26
Q

if pt paco2 is less than 35 you should do what?

A

don’t put patient on vent because pt is ventilating.
