Q

what is the benefit of pursed lip breathing?

A

pursed lips provide back pressure to small airways that maintain opening = improved gas exchange
by keeping airways open longer, air can be exhaled easier

Q

why does trunk elevation/sitting work to relieve dyspnea?

23
Q

what are indications to use ACTs?

A

excessive pulmonary secretions
impaired mucociliary transport
ineffective or absent cough

24
Q

when should ACTs be performed?

A

before or at least 30 minutes after the patient eats

25
Q

what should be given before ACTs?

A

inhaled bronchodilators

26
Q

what should be given after ACTs?

A

inhaled antibiotics, steroids –> better deposition if after

27
Q

what is an ACT for increased ventilation during activity that enhances mucociliary transport?

A

exercise! - it is an ACT

28
Q

what is postural drainage (PD)?

A

assuming one or more body positions that allow gravity to assist with draining secretions from individual lung segments

29
Q

the segmental bronchus of the segment to be drained must be positioned ______ to the floor

A

perpendicular

30
Q

how long should each position be maintained during postural drainage?

A

> /= 5-10 minutes

31
Q

a child with CF has the worst consolidation of fluid in the left lateral lobe, which lobe should you treat first?

A

left lateral lobe –>
segment with worst airway clearance should be drained first

32
Q

b. modify the position
c. you don’t need to change anything

A

b. modify the position

35
Q

a PT suspects involvement in the posterior basal segment of lower lobes for an obese patient. which of the following is a BEST position to consider?
a. positioned on abdomen, with head down, with 2 pillows under hips with foot of table elevated 20 inches

c. positioned on abdomen, with head down, with 1 pillow under hips with table flat
d. positioned on abdomen, with head down, with 1 pillow under hips with foot of table elevated 20 inches

A

c. – because they are obese, you have to modify their position

36
Q

what is percussion?

A

loosening retained secretions performed manually or with device via rhythmical clapping with cupped hands

37
Q

43
Q

what are the 4 stages of an effective cough?

A
  1. inhalation greater than tidal volume (> 60% of VC)

Q

what is the glottis?

A

opening between the vocal cords in the larynx

Q

what does the glottis do?

A

open and close with talking, coughing, breathing, swallowing, etc.

46
Q

how should you position your patient during an assisted cough strategy?

upright positioning
upward eye gaze

thoracic extension

48
Q

for exhalation during an assisted cough, what do you want to maximize?

A

intraabdominal and intrathoracic pressure via positioning or muscle contraction

49
Q

for increased cough strength, what should you tell your patient to do?

A

brace or splint abdomen

50
Q

what does the huffing technique help do?

A

prevent bronchoconstriction or collapse of weak airways
stabilizes bronchial walls and support structures

51
Q

what is the huffing technique?

A

mouth open throughout, O shaped
glottis doesn’t close over the trachea
chest and abdominal muscle contraction
forced exhalation that sounds like a loud forced sigh

52
Q

huffing technique:
long and slow forced exhalation moves secretions:
short and strong forced exhalation moves secretions:

A

in from the distal periphery
more proximally to cough

53
Q

what is the active cycle of breathing?

A

series of maneuvers to emphasize independent secretion clearance from distal to proximal and thoracic extension

54
Q

the active cycle of breathing incorporates what 3 things?

A

normal breathing
deep inhalation
huffing
