There are threee basic designs for O2 delivery systems. They are ; ___.
low-flow, reservoir, and high flow
Which o2 delivery system only delivers a portion of what a pt. needs with the patient making up the difference?
Low-flow delivery system
Which O2 delivery system delivers a variable performance?
reservoir delivery system
Which O2 delivery system delivers all and more of the patient's inspiration demand?
high-flow delivery system
The nasal cannula comes in four sizes (adult, ped, infant & preemie). This device is usually well tolerated. The Nasal cannula delivers an FIO2 of ______.
24-44 FIO2
Nasal cannulas are used with flow rates of _____.
1-6L/m
When using a nasal cannula, the FIO2 depends on ________.
how much room air the patient inhales in addition to the O2, how fast the patient is breathing
Hard and Fast rule: If you have a patient on greater than 4 L/m flow, then you should____.
add humidity
The nasal catheter is rarely used in modern health care facilities today. it has been replaced by the nasal cannula.It used flows of .25-8L/m.Nasal catheters deliver a FIO2 of _____.
.22-.45FIO2
A nasal catheter was inserted to just behind the ____ and then taped on the nose & forehead.
uvula
The trantracheal catheter is ____ placed in the trachea through the neck by a physician.
surgically
The transtracheal catheter is left in untill infected. It is left in permanently only if the patient has had a ______.
trachyotomy
Trantracheal catheters use _____ less O2 to achieve the same PaO2 by nasal cannula.
40%-60%
Transtracheal catheters are used with flow rates of _____L/m.
.25-4L/m
Infection complications are more common with the transtracheal catheter device because ____.
an actual incision had to be made, exposing the patient to bacteria invasion.
The reservoir cannula was designed to ______.
conserve oxygen
The reservoir cannula reduces oxygen use by as much as ____.
50%-75%
The reservoir cannula has a reservoir on either side of the nares or a pendant that is placed where the cinch would be. The reservoir itself has a ___ that holds the moisture and heat from expiration. The oxygen pools in the reservoir and is rebreathed.
cotton wick
The benefit of using a reservoir cannula is that a____ can be used for the good of the patient. You could also increase the flow rate if necessary without causing nose bleeds.
lower flow rate
Reservoir masks are the most commonly used reservoir systems. There are three types: ______.
Simple, partial rebreathing,& non-rebreathing
This mask is no longer in use.
partial rebreathing mask
The simple mast typically runs at ___ L/min and is used in recovery.
6-10 L/m
The SIMPLE rule for the SIMPLE mask is that flow must be ^5L/m in order to ______.
flush out exhaled CO2
The FIO2's for a simple mask is ___.
.4-.6 percent
A non-rebreathing mask runs at ____ L/m and is used on adults as well as the big gun in ER while decisions are being made as to what to do.
10-15L/m
The FIO2's for a non-rebreathing mask is ___.
.55-.70 percent
With a non-rebreathing mask, the flow has to be high enough that the resevoir air bag _______.
stays inflated
High flow systems use air entrainment or ____ systems.
blending (venturi)
High flow systems can ensure a ___ FIO2.
fixed or constant
The two most common high flow systems that are used on adults are;_____.
Venturi mask and jet nebulizer(cool mist)
What device would you select for an adult pt that is mildly hypoxic ( PAO2 of 60-80) if you desired a fixed FIO2 level?
AEM, air-entrainment nebulizer or a blending system
What device would you select for an adult pt that is mildly hypoxic(PAO2 of 60-80) if you desired a variable FIO2 level?
nasal cannula, nasal catheter or tracheal catheter
What device would you select for an adult pt that is moderately hypoxic(PAO2 of 35-60%) if you desired a fixed FIO2 level?
air-entrainment nebulizer or a blending system
What device would you select for an adult pt that is moderately hypoxic (PAO2 of 35-60%) if you desired a variable FIO2 level?
a simple mask (and an air-entrainment nebulizer?)ask in class
What device would you select for an adult pt that is severely hypoxic (PAO2 of ^60%) if you desired a fixed FIO2 level?
a blending system
What device would you select for an adult pt that is severely hypoxic (PAO2 of ^60%) if you desired a Variable FIO2 level?
partial rebreather or a nonrebreather
