Continuous Nebulization/VM to NC Problems

Given 30 ml/hour of solution is nebulized per the manufacturers’ insert

1)You and the MD decide that the patient needs 3cc/hr for three hours

a)What is the amount of drug you would put in the nebulizer?

b) What is the total output of the nebulizer?

c) What amount of normal saline would you mix with the drug?

a) 3cc/hr x 3 hours =9 cc drug

b) 30ml/ hour x 3 hours =90 ml of total solution

c) 90 ml solution -9cc of drug =81 cc of NS

2)You and the MD decide that the patient needs 4cc/hr for five hours

a)What is the amount of drug you would put in the nebulizer?

b) What is the total output of the nebulizer?

c) What amount of normal saline would you mix with the drug?

a) 4ccdrug/hr x 5 hours =20 cc of drug

b) 30ml/hr x 5 hours =150 ml total solution

c) 150 ml-20cc/drug = 130 ml of saline

3) You and the MD decide that the patient needs 2cc/hr for four hours

a)What is the amount of drug you would put in the nebulizer?

b) What is the total output of the nebulizer?

c) What amount of normal saline would you mix with the drug?

a) 2cc/hr x 4 hours =8 cc of drug

b) 30ml/hr x 4 hours = 120 ml total solution

c) 120 ml -8 cc drug =112 cc of saline

You ar going to switch the following patients from Venturi masks to nasal cannulas, so that they can enjoy their first pureed lunch. How many liters per minute must they be on?

General formula (FIO2 on VM) = 21%(RA) + 4(lpm on NC)

a) 50% VM b) 35% VM c) 24%VM d) 28% VM e) 40%VM

a) 50 % =21%(RA) + 4x

29% = 4x

7 lpm = x

b) 35% =21% + 4x

14% = 4x

3.5 lpm = x

c) 24% =21% + 4x

3% =4x

¾ lpm or 1lpm = x

d) 28%= 21% + 4x

7% = 4x

2lpm = x

e) 40% =21% + 4x

19% = 4x

5 lpm =x
