What do you do if pulse ox results are low? Reapply to another site
If using continuous pulse ox monitoring, what should you do? Assess skin integrity and relocate sensor every 2-4 hours.
Is O2 an explosive? No but it supports combustion
How are oxygen cylinders stored? Upright secured
What should you do before transporting a patient on O2? Check the level in the cylinder
