Continuous Nebulizers
• 10-15 mg/Hr of Albuterol
• Available Albuterol Concentrations
– Concentrate= 2.5mg/0.5cc(mL)
• Available Albuterol Concentrations
– Bottle= 2.5mg/0.5cc(mL) or 5mg/1cc(mL)
• Available Albuterol Concentrations
– Unit Dose= 2.5mg/0.5cc(mL) with 2.5cc(mL)NS
Continuous Nebulizer Output
Continuous Nebulizer Calculation
• 45mg albuterol over 3 hours, neb output is 20
ml/hr
15mg of albuterol per hour for 3 hours, neb
output is 20
1. How much albuterol do you need?
1. 45 mg
2. How many vials is that (or CC if bottle)
1. 45/2.5mg
(or 45/5x2)
• How much solution are we adding?
– Unit dose = vials x 3 (18 x 3)= 54 cc
– Concentrate= vials x .5 (18 x .5)= 9 cc
• What is total amount of solution needed to run
for given time
– Output of neb x hours it will run (20 x 3= 60cc)
• How mcuh saline do we add to run for given
time? (total output- albuterol solution)
– Unit dose= 60- 54= 6 cc saline
– Concentrate= 60 – 9= 51 cc saline
• 20 mg per hour for 4 hours, neb output is 25
ml per hour
• 20mg x 4= 80 mg total = 32 vials (80/2.5)
• Unit dose= 32x3= 96 cc of solution
• Concentrate= 32x.5= 16 cc of solution
• Total output for 4 hours= 100 ml
• 100-96= 4 cc saline
• 100-16= 84 cc saline
