Q

What are the 4 MOA that helps to get mucus out?

A
  1. soften secretion
    - ->by hydrating airway by adding humidity or mucolytic
  2. Loosen secretion
    - ->use vibration technique to shake secretion out of the bronchial
  3. Bronchodilation
    - ->use medication to open up airway which assists coughing up mucus
  4. Mucus expelling
    - -> by coughing

25
What cause acute cough
- -> sudden onset | - ->short course
26
What cause chronic cough
- ->more than 3 wks - ->caused by postnasal drips - ---Postnasal drip is extra mucus felt in the back of the nose and throat caused by the glands
27
What cause paroxysmal?
- ->periodic - ---frequent and violent coughing - ->prolonged - ->due to asthma, aspiration, left heart failure
28
What cause barking
- seal like cough - croup - ->swelling and narrowing in the voice box
29
What cause dry hacking
- viral infection - irritant gases - interstitial lung disease
30
What cause productive cough
- chronic bronchiectasis - cystic fibrosis - bronchitis
31
What causes cough in the morning
- chronic bronchitis | - smoking
32
What causes with positional change
- gastroesophageal reflex - left heart failure - bronchiectasis
33
What is the 4 main phases of cough
1. irritant 2. efferent signal 3. respiratory pause 4. glottis opens
34
What are some cough techniques that should be taught to patients
a. active cycle of breathing b. forced expiratory technique c. autogenic drainage d. manually assisted cough e. in-exsufflator machine f. muscle training
35
Who should be taught on about coughing?
1. post heart, abdomen, thorax patients 2. trauma patient 3. COPD patient 4. post-ventilated pt - ->muscles are weaker
36
What are the main indication of cough therapeutic technique?
- removal of secretion from central airways - reverse atelectasis - prophylaxis against postoperative - routine bronchial hygiene - as a part of other therapy
37
What is the ACBT consist of
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
What are the 2 types of huffing?
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
How is the deep breathing of ACBT performed?
1) take long, slow, deep breath in, through nose 2) breath out gently like a sigh * do 3 -5 deep breath * try 2-3 sec breath hold after inhalation
40
WHat is the huffing
Forced expiratory technique - a force expiration at mid-low lung volumes with open glottis
41
what is the result of huffing
less bronchiolar collapse | helps moves sputum up the airway , helps to clear it easily
42
How to perform huffing
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
What is autogenic drainage
- mobilizes mucus with breathing pattern | - no coughing until sequence is done
44
How many phases are there in autogenic drainage
phase 1: a full inspiratroy capacity maneuver followed by breathing at low lung volumes ->unsticks peripheral mucus 2. breathing at low to mid lung volumes to collect mucus in middle airways 3. evacuation phase, mucus is readied for expulsion from large airways
45
What is the positioning for autogenic
position | sitting, shoulders internally rotated, head flex slightly and feet supported
46
How to do manually assisted cough
1,build up good tidal volume -by small breaths 2.presses upwards on abdomen during exhalation to clear secretion
47
What are some modification done to manually assisted cough
for surguical patient - splint with hands, pillow for neurimuscular disease - compress chest/diaphragm to get secretion out COPD patient - pursed lip breathing - fet
48
What is the in fexsufflator cough machine
it improves peak cough expiratory flow rate
49
What is the normal peak cough expiratory flow rate
6-12 L/min
50
What is the cough expiratory flow rate in patient with NMD
unassisted: 1.81 assisted: 4.27 exsufflator: 7,47
51
What is the indication for cough assist T70
1. secretion clearance for chronic lung condition | 2. neuromuscular disease
52
What is the contraindication for cough assist
emphysema pneumothroax pneumo-mediaastinum
53
What does cough assist work
it loosens, mobilize, clear secretion via high frequency oscillatory vibration - applies +ve pressure then shifts to -ve pressure - the pressure produces high expiratory flowrate which clears secretion
54
What are the interface that cough assist can connect to
face mask, mouth piece, TT, ETT
55
Pressure of cough assist
insp 20-40 cmh2o for 1 - 2sec exp -20-40 cmh2o for 1 sec pause 1-2sec
56
What is the purpose of muscle training
- adjuncts for secretion clearance
57
What are some muscle training devices
1. insp muscle trainer - ->breathing in 1 -way valve - -->e.g. threshold IMT, PFLEX 2. exp muscle trainer - ->resistance increases as patient gets stronger 3. physical condition
58
What is the indication of lung expansion therapy
1. prevent atelectasis , especially in post op patient | 2. assist with cough or secretion mobilization
59
What is the methods of lung expansion therapy
1. breathing exercise 2. incentive spirometry 3. lung expansion therapies - ->manual insufflation - ->IPPB - ->in/exsufflator
60
What is PEP therapy
- exhalation against fixed resistance - sustained effort * NO VIBRATION range -10-20 cmh2o *can combine aerosol
61
What is OPEP
- 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
What is indication of pursed lip breathing
for COPD patient as they gas trap due to early airway closure -->it moves EPP so closure occurs at lower lung volumes
63
What is incentive spiroemetry?
- required sustained maximal inspiration (SMI) - mimics yawning - prevents or correct atelectasis
64
how to perform IS
slow inspiration from FRC to TLC with 5 - 10 sec breaths hold
65
what is some concern about IS
require active participation by patietn must be performed frequently
66
What are 2 equipment for IS
flow dependent | volume dependentq
67
What is some recommendation for IS
1. not recommended for pre-post op prevention of atelectasis ALONE 2. not recommended for post upper abdomen surgery
68
What is the rationale or mechanism that helpe prevents atelectass
- increase transpulmonary pressure and inspiratory volumes - improves resp muscle performance - re establish pattern of deep periodic breahting
69
What are some lung expansion therapies
1. manual insufflation - ->via BVM with mask 2. mechanical ventilation - ->IPPB - ->CPAP,EPAP 3.cough machine, cough assist
70
WHat is the setting of IPPB?
- uses preset pressure to deliver a larger Vt than normal Vt - pt breathing sponatenously for 15 - 20 mins, - q 1 - 6h
71
Who should use IPPB?
NON intubated , patient controlled
