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 it has been replaced by the nasal cannula.It used flows of .25-8L/m.Nasal catheters deliver a FIO2 of _____.

|
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: ______.
