  1. Bubble humidifier
    • Gas goes through the backchannel and then bubbles back up pushing water down and out to pt
    • Nasal Cannula or Face Mask ONLY
    • Flow rates of equal or greater than 10 L/min (can produce aerosol at flow rates ≥ 10 L/min)
    • Recommended for flow rates 2-6 L/min
    • Aka diffuser
    • -diffuser allows more output
  2. Wick humidifier
    • Hudson Heater
    • This device has a Concha-Column produces humidification using the evaporation process to ensure minimal resistance to gas flow.
    • The wired-corrugated tube helps to maintain a constant temperature along the tube. This helps to reduce the “rain” forming when there is a crash of hot and cold temperatures (cold due to the surroundings; room temperature).
    • This heater has a hose for water recycling that connect at the top of the reservoir system (prolonging the duration of the sterile water reservoir)
  3. Room humidifier (Spinning disk)
    The ones you buy at CVS or Walmart. Are used to humidify air in a room. Point machine directly over patient to humidify the air the patient breathes
  4. HME’s (Heat and Moisture Exchanger)
    • “Artificial nose”
    • Change every time check on pt is able, if not NO MORE THAN 3 days
    • Filtration can be added (HMEF)
    • Has mechanical deadspace
    • Short term use
    • Exhaled heat and moisture are captured by condenser during exhalation; cool and dry inspired gas is warmed and heated as it flows through condenser
    • Standard output of >30mg/L
    • Contraindications include:
    • Thick, copious, bloody sputum

    Expired tidal vol of less than 70%

    Body temp less than 89.6F (32 CO)

    Pt receiving in line aerosol drugs

    Pt on noninvasive ventilation
  5. Misty-Ox HiFi
    • High Flow Device
    • Can be connected to either connection on thorpe tube

    • Can be run at a flow as high as 40 LPM
  6. Heated wire circuits
    Keep temp the same through whole system
  7. Heated
    are ACTIVE humidifiers

    Provides 100% relative humidity

    Bland aerosol therapy

    LVN or VMN
  8. non heated
    are PASSIVE humidifiers
  9. 2.Know difference between LOW flow and HIGH flow humidifiers

    (standard vs. Misty-Ox LDH, will see in lab)
  10. Be able to label parts of various humidifiers
  11. 4. Understand the principle of Humidity Deficit
    Humidity deficit helps us understand and allows to know what is the amount of water vapour the body must add to the inspired gas to achieve saturation at body temperature (37 Co)
  12. CYLINDER DURATIONS
    • Know how to calculate either E or H durations (Calculator WILL be on table to assist)
    • E-.28

    H-3.14


    Duration of Flow= (Psig x Cylinder size) / flow


    Psig- if not given use 2200

    Gas duration is measured in min


    Amount of gas in cylinder= Liquid O2 (lb) x 860/2.5lb/L

    Duration of gas= Amount of gas in cylinder/Flow
  13. AEM
    Know your AIR:OXYGEN RATIOS


    How to calculate TOTAL FLOWS

    Understand the principle of operation
  14. Know your AIR:OXYGEN RATIOS
    “Magic Box” or memorize equations or formula

    .24 -- 25:1

    .28 -- 10:1

    .31 -- 7:1

    .35 -- 5:1

    .40 -- 3:1

    .50 -- 1.7:1

    .60 -- 1:1

    .70 -- .6:1
  15. How to calculate TOTAL FLOWS
    Total flow= L/min x Air Ratio #

    NC .24-.44

    TC .22-.35

    SM .35-.50

    OM .24-.90

    PRBM .40-.70

    NRBM .60-.80


    High Flow devices:

    HFNC .21-1

    AEM .21-1

    AEN .06-.08
  19. Know ALL of the flow ranges of ALL modalities, High and low flow

    • Bourdon gauge
    • Which is Pressure Compensated, Which is gravity dependent?


    Types – Standard Flow, High Flow, Low Flow.



    Purpose of the 50-psi port (sometimes referred to as the Power Port)
  22. Know the functions and indications for the usage of both Thorpe tube and

     Bourdon gauge
    Thorpe Tube:

    • Two flow sizes offered, smaller (>15/16 is for peds)
    • Can be uncompensated or compensated

    Bourdon Gauge:

    • The gauge displays a predictable outlet flow
    • Measures pressure
  23. Which is Pressure Compensated, Which is gravity dependent?
    Pressure Compensated is the Bourdon Gauge

    Gravity Dependent is the Thorpe Tube


    *Bourdon Gauge experiences backflow and can give a faulty reading

    *Thorpe tube CAN be used for transport except that you will have to pick it up right to read the

    volume
