Airway stuff Flashcards
how much sputum sample is required
5-10mL
what to do to decrease trauma when using a nose suction catheter
apply suction 5-10secs and release 1-2 secs
rotating catheter during withdrawal
what does increase in tactile fremitus indicate
denser or inflamed tissue - can be pneumonia
what does decrease in vocal fremitus mean
air trapping and decreased density of lung space, or fluids; decreasing transmission of lower frequency sounds
Percussion: flat, dull, hyperresonant sounds
flat: over solid areas like bones
dull: dense like heart or liver
hyper resonant: loud and in kids or thin adults, or hyperinflated with air
Nasal cannula FiO2 range
22-50%
Nasal cannula O2 flow rate range
1-6L
simple face mask FiO2 range
40-60%
simple face mask O2 flow rate range
6-10L
nonrebreather face mask FiO2 range
60-95%
nonrebreather face mask O2 flow rate range
10-15L
Venturi mask FiO2 range
24-60%
venturi mask O2 flow rate range
4-12L
face tent FiO2 range
28-100%
face tent O2 flow rate range
8-12L
what is tidal volume
amount of air breathes into or out of lungs in a single breath
room air is how many FiO2
21%
when are postural drainage typically done
before meals and at bedtime to avoid gastric reflux & vomiting
nasopharyngeal airway (nasal trumpet) measurement
reach from tip of nose to the earlobe;
largest outer diameter that fits comfortably in the nares
oropharyngeal airway - why use it, requirements
upper airway patent when at risk for becoming obstructed by tongue or secretions;
pt needs to be asleep
why use nasopharyngeal airway
upper airway patency; won’t stimulate gag reflex so pt can be awake
why use endotracheal tube
general anesthesia or mechanical ventilation up to 14 days
why use tracheostomy tube; requirements
long-term airway support; requires surgical procedure for placement
purpose of Yankauer suction catheter
clear secretions from mouth
between mouth and trachea which should be suctioned last
mouth - clean
trachea - sterile
SO trachea first, mouth last
how often should cuffed endotracheal tubes be repositioned
q12hrs to help prevent irritation to oral mucous membranes
recommended cuff pressure for ET tube
20-25mmHg
percussion vs. vibration
percussion dislodges by striking
vibration increases turbulence
in-line suctioning is replaced how frequently
trick question
it get replaced with the ventilation tubing system can is reused until then
