What are we facilitating/changing when we give a pt medications for post-op pain?

Gate Theory - what fibers close the gate?

Large myelinated

c fibers small, dull

T/F

Nitrous is a selective CNS depressant

False

*non-selective

T/F
Nitrous is the wimp of all inhaled drugs
(weak one)

True

What sedative drug is only available for oral administration?

This is what class of drug?

triazolam Halcion

benzodiazepene

What are 4 different ways to administer sedation?

Oral

Intramuscular

Inhalation

What is the capacity (in Liters) for the e-cylinder for Oxygen?

If the tank is 1/2 full, how much do we have?

*x number of liters/min, can figure out how long we can run oxygen if we know this number

625 L

312.5 L

What type of Flowmeters do we see on our Nitrous Units?

*most common

*Ball

Rod

Rotameter

Benzodiazepenes are _____ drugs only and don't provide _______

sedative analgesia

Small, incremental doses of a drug until desired clinical effect is observed

Titration

Titration is the ____ dose of a drug until _____ is observed

incremental desired clinical effect

When we administer Nitrous, what do we begin and end the procedure with? If you reach the max dose, what then?

100% Oxygen Nothing - failure

With the units we use, what is the Maximum amount of Nitrous we can administer?

70%

If the Nitrous tank is 35% empty (65% full), what is the PSI?

750-800 psi

The Oxygen Unit is _____ PSI when full The Nitrous Unit is _____ PSI when full PSI remains constant until it is _____ full

2000 750-800 25%

T/F | You can administer Nitrous if you don't have Oxygen available

False *need oxygen - it is the fail safe built into the system

How much Oxygen is in the E-Cylinder when full? * we'll have to figure something out with this number * most likely how long until empty with a Flow Rate

625 L

What is the Primary function of the Reservoir Bag? Respiratory effort is also seen and from this we can determine the...

Additional volume for deep breathing Flow Rate (e.g. 6 Liters)

If an Oxygen tank is half full and Flow Rate is 5 LPM, how much time do you have left for the procedure if you stop at 30% full on Oxygen tank?

50% is 312.5 so, if stop at 30%, only have 20% left 130 Liters @ 5 LPM = 26 minutes
