37
Q

What is the ACBT consist of

A
  1. breathing control
    - breath at tidal volume for 5 -10 sec which helps to increase VC for a good cough
    2.deep breathing (thoracic expansion)
    3.huffing
    (fogging up window)
  • performed in a cycle until no more secretion
  • might be used with postural drainge
38
Q

What are the 2 types of huffing?

A

1) short and forceful
- ->moves sputum from upper chest to trachea
- ->use this when sputum is ready to come out

2) long and unforceful
- moves sputum up from bottom of the chest
- take small to medium breath in then huff

39

40
Q

WHat is the huffing

A

Forced expiratory technique

  • a force expiration at mid-low lung volumes with open glottis
41
Q

what is the result of huffing

A

less bronchiolar collapse

helps moves sputum up the airway , helps to clear it easily

42
Q

How to perform huffing

A
  1. exhale via open mouth
  2. squeeze air quickly from lungs
  3. use abdomen muscle to help squeeze breaths out, follow by breath control
43
Q

A
  • mobilizes mucus with breathing pattern

- no coughing until sequence is done

44
Q

How many phases are there in autogenic drainage

A

phase 1:
a full inspiratroy capacity maneuver followed by breathing at low lung volumes
->unsticks peripheral mucus

  1. breathing at low to mid lung volumes to collect mucus in middle airways
  2. evacuation phase, mucus is readied for expulsion from large airways
45

A

position

sitting, shoulders internally rotated, head flex slightly and feet supported

46

  • exhalation against fixed resistance
  • sustained effort
  • NO VIBRATION

range
-10-20 cmh2o

*can combine aerosol

61
Q

What is OPEP

A
  • patient exhales via a adjustable resistance level that creates back pressure felt at lung

Expiratory pressure stents airway open, opening up collapse alveoli

intermittent resistance creates oscillation pressure and increase expiratory flow—>helps to dislodge mucus to central and upper airway

62
Q

What is indication of pursed lip breathing

A

for COPD patient as they gas trap due to early airway closure

–>it moves EPP so closure occurs at lower lung volumes

63
Q

What is incentive spiroemetry?

  • required sustained maximal inspiration (SMI)
  • mimics yawning
  • prevents or correct atelectasis
64
Q

how to perform IS

slow inspiration from FRC to TLC with 5 - 10 sec breaths hold

65
Q

what is some concern about IS

require active participation by patietn

must be performed frequently

66

flow dependent

volume dependentq

67
Q

What is some recommendation for IS

A
  1. not recommended for pre-post op prevention of atelectasis ALONE
  2. not recommended for post upper abdomen surgery
68
Q

What is the rationale or mechanism that helpe prevents atelectass

A
  • increase transpulmonary pressure and inspiratory volumes
  • improves resp muscle performance
