  1. What’s the volume in a tank (E-cylinder) when the pressure reads 500PSI?

    2.  

    500 psig = 23% full

    2200 psig

     

  2. How many hours will an H-cylinder last if it runs at 5 liters/min from full?

    3.  

    2200 x 3 = 1320 min/60min 1hr = 22 hrs

    5 LPM

     

  3. How long will an H-cylinder last when it reads 1000PSI? Flow = 8LPM

    4.  

    1000 psig x 3 = 375 min/60 min/hr = 6.25 hrs

    8 LPM

     

     

  4. How long will an E-cylinder run if its liter flow is 1.5 liters/min and the pressure 1800 PSI?

    5.  

    1800 x .3 = 360 min/60min/hr = 6hrs

    1.5 LPM

     

     

  5. How long (with a G-cylinder ) will oxygen run if it is set on 1liter/min and the pressure reads 650 PSI? (factor for G=2.41)

 

650psig x 2.41 = 1566.5 min/60 min/ = 26.1 hrs

1 LPM

 

ENTRAINMENT/TOTAL FLOW PROBLEMS- RESP 101

 

 

NAME

 

What is the total flow of gas going to the patient in each of the following: Total Parts X LPM = Total Flow

 

  1. Venturi-mask on 24% and 4LPM

    2.  

    24% 25:1 25 + 1 = 26

    26 x 4 = 104 1pm

     

  2. Nebulizer 60% and 10 LPM

    3.  

    60% 1:1 1+ 1 = 2 If hospital policy

    2 x 10 = 20 1pm 20 x 2 = 40 1pm

     

     

  3. Nebulizer on 40% and 8 LPM

    4.  

    40% 3:1 3 +1 = 4

    4 x 8 = 32 1 pm

     

     

     

  4. Venturi Mask on 50%, 10 LPM.

    5.  

    28% 10:1 10 + 1 = 11

    11 x 3 = 33 LPM

     

     

  5. Nebulizer on 30%, 8 LPM

    6.  

    30% 8:1 8 +1 = 9

    9 x 8 = 72 LPM

     

     

  6. Nebulizer on 50%, 10 LPM.

    7.  

    50% 2:1 2+1 = 3 Hospital Policy 2 nebs

    3 x 10 = 30 LPM 30 x 2 = 60 LPM

     

  7. Nebulizer on 60%, 12 LPM

60% 1:1 1+ 1 = 2 Hospital Policy 2 nebs

2 x 12 LPM = 24 LPM 24 x 2 = 48 LPM
