Study These Flashcards

Atelectasis

Recommended suction pressure for adults is:

a. 50-80 mmHg
b. 100-120 mmHg
c. 120-150 mmHg
d. 80-100 mmHg

Study These Flashcards

c. 120-150 mmHg

Recommended suction pressure for neonates is:

a. -50-80 mmHg
b. -100-120 mmHg
c. -120-150 mmHg
d. -80-100 mmHg

Study These Flashcards

d. -80-100 mmHg

Recommended suction pressure for children:

a. -50-80 mmHg
b. -100-120 mmHg
c. -120-150 mmHg
d. -80-100 mmHg

Study These Flashcards

b. -100-120 mmHg

T/F: Nasotracheal suctioning is indicated for patients who have secretions but do not have an artificial airway in place.

Study These Flashcards

True

Select each that best defines sputum samples:

I. Identify organisms that affect airway
II. Pts can cough strongly into sterile cup

Study These Flashcards

I. Identify organisms that affect airway

II. Pts can cough strongly into sterile cup

Specimen cup is called:

Leuken's trap

The primary cause of airway injury is:

Tube friction Ex)

You should maintain cuff pressures at:

25-35 cmH2O

Which cuff is designed to seal trachea with atmospheric pressure in cuff? Not commonly used in pts who already developed tracheal injury:

Foam cuff

Which cuff is low volume, high-pressure design that maximizes airflow around tube when deflated?

Tight-to-shaft (TTS)

T/F: The Tight-to-shaft (TTS) is filled with air because it is made of porous silicone material.

False Inflated with WATER, not air because it is made of porous silicone material

T/F: Minimal leaking is not recommended because it allows a small leak to remain.

True

T/F: Minimal occluding volume technique is preferred over minimal leak technique.

True Minimal occluding volume technique is preferred, it is inflating cuff just enough to eliminate leak

Most common method for securing airway is:

Taping Other options: commercial ETT stabilizers, cloth/velcro/steel ties for trach

The tube tip should be approx:

3 to 5cm above carina | or between 2nd and 4th tracheal rings

What % relative humidity is needed at BTPS?

100% RH at BTPS (isothermic boundary)

HME gives about what % RH?

70% RH

Heated wick or membrane humidifier gives what % RH?

100%

If patient has thick, hard to move secretions you should switch from the HME to the:

Heated humidifier

T/F: There is less chance of contamination from rainout with HME.

True

T/F: Heated wire circuit for heated humidifier increases rainout.

False DECREASES rainout

Safest option in reversing tube obstruction (for ex, kinking or pt biting tube) is to:

Swap the tube

If there is a herniation of cuff over tip, the first thing you should do is:

Deflate the cuff If that fails, try to pass suction catheter through tube then swap tube

What should you use to loosen mucus?

Saline

Cuff leaks impair tidal volume in what way?

Reduce delivery of tidal volume

If pilot tube or valve is leaking, the first thing you should do is:

Change the tube as soon as possible

Ruptured cuff immediately indicates:

Extubation & reintubation using endotracheal tube exchanger
