Flashcards in Airway maintenance Deck (35):
Suctioning can be performed in which airways?
upper airway (oropharynx)
lower airway (trachea and bronchi).
You suction the oropharynx with
suction through the nose
suctioning through the artificial airway
T/F Tracheal suctioning through the mouth should be avoided because it causes gagging.
What kind of suctioning is when the catheter is inserted until resistance is met and then withdrawn approximately 1 cm before applying suction
What kind of suctioning is when the catheter is advanced to a predetermined depth, which is usually the length of the airway plus the adapter.
What kind of suctioning is recommended in infants and children
T/F Patients should be suctioned according to a predetermined schedule?
the patient should be assessed for clinical indicators, such as rhonchi heard on auscultation, which suggest the need for suctioning, instead of scheduled suctioning.
Too large a suction catheter combined with negative pressure can cause
atelectasis and hypoxemia.
The diameter of the catheter should be less than __% of the internal diameter of the artificial airway in adults.
Before suctioning what FIO2 and how long
delivery of 100% oxygen (O2) for 30 to 60 seconds
T/F If any major change is seen in the heart rate or rhythm during suctioning, the RT should immediately stop suctioning, administer O2 to the patient, provide ventilation as needed, and notify the nurse and physician.
Atelectasis can be caused by removal of too much air from the lungs in a short time. This complication can be avoided by doing what 4 things.
(1) limiting the amount of negative pressure used
(2) keeping the duration of suctioning as short as possible,
(3) using the appropriate size suction catheter
(4) avoiding disconnection from the ventilator.
What type of suctioning is indicated for patients who have retained secretions but do not have an artificial tracheal airway.
While performing nasotracheal suctioning as the catheter enters the lower pharynx, the patient should assume what position
Male Or Female.
an orotracheal tube should initially be inserted to the 21- to 23-cm mark at the teeth in
Male Or Female.
An orotracheal tube should initially be inserted to the 19- to 21-cm mark at the teeth
If the patient still needs an artificial airway after approximately 14 days. What should be considered?
The benefits of a tracheostomy versus oral or nasal intubation are
less need for deep sedation
shorter weaning time,
shorter intensive care unit (ICU) and hospital stay.
What kind of tracheostomy tube is a double cannulated tube that has an opening in the posterior wall of the outer cannula above the cuff
What type of ET tube limits the cuff pressure to 16 to 18 mm Hg.
What kind of cuff is designed to seal the trachea with atmospheric pressure in the cuff .
The foam cuff
T/F The foam cuff is not commonly used except in patients who have already developed tracheal injury.
What are Four reasons for a tube to be obstructed
(1) the kinking of the tube or the patient biting on the tube
(2) herniation of the cuff over the tube tip
(3) obstruction of the tube orifice against the tracheal wall
(4) mucus plugging
A small cuff leak can be detected by
noting decreasing cuff pressures over time
What would you do if the cuff ruptures and the patient is being mechanically ventilated. ,
extubation and reintubation
This procedure can be done via the standard reintubation procedure or by using an endotracheal tube exchanger
What can mimic a cuff leak?
endotracheal tube that is positioned too high in the trachea and near the glottic opening
What consists of a short tube and a small mask that is inserted deep into the oropharynx.
T/F The insertion of the LMA requires the use of additional equipment?
LMA. When the cuff is in place, it is inflated to a maximum of _____ . Inflation causes the mask to rise slightly out of the mouth.
60 cm H2O
Contraindication for LMA
conscious or semicomatose patient because of stimulation of the gag reflex.
What tube is inserted blindly through the oropharynx and into the trachea or the esophagus. One cuff seals the oropharynx. The second seals the trachea or the esophagus.
The double-lumen airway (Combitube)
the insertion of a visualization instrument (endoscope) into the bronchi.
