|
What is important to know in regards to specific entrainment ratio (Venturi)?
|
- the same FIO2 always has the same ratio
- altering flow rate will not alter ratio |
|
|
How do you alter the FIO2 in a Venturi setup?
|
- by altering the port
|
|
|
What is important to know when using a venturi system?
|
- watch for bed sheet (covered port will increase FIO2 but decrease flow)
- always place collar to prevent blockage |
|
|
What must be adjusted when switching a patient from a nasal cannula to a venturi setup?
|
- liter flow will need to be adjusted to insure correct FIO2
|
|
|
What is the FIO2 range for a venturi mask?
|
- 0.24-0.50
- high flow, but normally low concentrations |
|
|
What is a mist tent (croupette)?
|
- high flow system
- plastic tent large enough to enclose child - primarily used to provide aerosol therapy to children with croup - air conditioned |
|
|
What is the LPM & FIO2 delivered by a mist tent?
|
- 12-15 LPM to prevent CO2 buildup
- provides approximately 40% FIO2 |
|
|
What is an isolette ?
|
- high flow chamber designed to provide a thermally controlled O2 enriched, humid environment for newborns
- access provided through side ports to help maintain consistent FIO2 |
|
|
What is a head box?
|
- enclosure that fits over the head of a newborn
- warmed & humidified O2 is supplied to box by large bore tubing |
|
|
What is the minimum flow rate for a head box?
|
- 7 LPM to flush out CO2
- higher flow may produce harmful noise |
|
|
What must the flow be for an aerosol setup?
|
- 3 times the minute volume
|
|
|
What may be necessary for an aerosol setup at high FIO2's (greater than 0.60)?
|
- tandem setup may be necessary
|
|
|
What is another name for the "T" piece? What is it used for?
|
- Briggs adapter
- intubated patients & trached patients |
|
|
What does an aerosol setup deliver?
|
- high humidity along w/ a precise FIO2
