19
Q

T/F

Nitrous is a selective CNS depressant

A

*non-selective

20
Q

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

A

True

21

This is what class of drug?

A

triazolam Halcion

benzodiazepene

22
Q

What are 4 different ways to administer sedation?

A

Oral

IV

Intramuscular

Inhalation

23
Q

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

A

625 L

312.5 L

24
Q

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

*most common

A

*Ball

Rod

Rotameter

25
Q

Benzodiazepenes are _____ drugs only and don’t provide _______

A

sedative

analgesia

26
Q

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

A

Titration

27
Q

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

A

incremental

desired clinical effect

28
Q

When we administer Nitrous, what do we begin and end the procedure with?

If you reach the max dose, what then?

A

100% Oxygen

Nothing - failure

29
Q

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

A

70%

30
Q

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

A

750-800 psi

31
Q

The Oxygen Unit is _____ PSI when full

The Nitrous Unit is _____ PSI when full

PSI remains constant until it is _____ full

A

2000

750-800

25%

32
Q

T/F

You can administer Nitrous if you don’t have Oxygen available

A

False

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

33
Q

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
A

625 L

34
Q

What is the Primary function of the Reservoir Bag?

Respiratory effort is also seen and from this we can determine the…

A

Additional volume for deep breathing

Flow Rate (e.g. 6 Liters)

35
Q

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?

A

50% is 312.5

so, if stop at 30%, only have 20% left

130 Liters @ 5 LPM = 26 minutes
