Bronchial hyigene Flashcards
What are the goals of Bronchial hyigene
- interrupt cycle of lung tissue destruction
- decrease infection and illness
- improve quality of life
- mobilize secretions and prevent accumulation
- improve efficiency and distribution of ventilation
- improve cardiopulmonary reserve
What are the 4 MOA that helps to get mucus out?
- soften secretion
- ->by hydrating airway by adding humidity or mucolytic - Loosen secretion
- ->use vibration technique to shake secretion out of the bronchial - Bronchodilation
- ->use medication to open up airway which assists coughing up mucus - Mucus expelling
- -> by coughing
What does mucus retention lead to?
mucus retention
mucus plugging/obstruction
lung infection
lung damage
What are the 2 indication for secretion clearance
- lung condition lead to excess sputum
- Acute: pneumonia, exacerbation of COPD, acute respiratory failure, acute lobar atelectasis
-Chronic: CF, bronchiectasis
- patient with difficulty clearing secretion and coughing
- immobile patients
- post-op patient with abdomen and thorax wounds that make them breath shallowly
- patient with neuromuscular disease (Guillian Barre, Amyotrophic lateral sclerosis, Myasthenia gravis)
What are 6 bronchial hygiene technique
- chest physiotherapy
- assisted cough maneuvers
- lung volume recruitment
- suctioning (ONT)
- sputum induction
- humidity therapy
What techniques are include in chest physiotherapy?
a) postural drainage
b) percussion
c) chest vibration
What is postural drainage
put pt in position that uses gravity to drain secretion into bigger bronchial for removal
What is the technique of postural drainage?
1) patient is position so that affected lung segment are superior to the carina
2) position is held 3-15 or as tolerated
3) total treatment time is 30 - 40 mins
4) cough method is used simultaneously to enhance removal
Who should be treated with postural drainage
its most effective for pt with excessive sputum production (<25 to 30ml/day)
what are some addition technique when using postural drainage
1) head angle should exceed 25 degree below horizontal line to achieve maximum effect
2) ensure systemic and airway hydration
What are the precautions of postural drainage
1) Positional desaturation
2) increase ICP
3) positional hypotension
4) bronchospasm
5) dysrhythmias
6) pulmonary hemorrhage
7) mobilizing secretion to other areas of lung, increasing frequency of suctioning
What are the relative and absolute contraindication of postural drainage
Relative: Injury - Cranial / opthalmic - thorax Disease - pulmonary - cardiovascular - abdominal
Absolute:
- unstabalized head/neck injury
- hemodyanmic instability
How often should a postural drainage be done
Q4-6hr PRN for mechanically ventilated pt
PRN for patient response to therapy
How to position critical care patients with postural drainage
- PD is used to improve V/Q matching in critical care patient
What is the expected outcome of secretion removal
- improve breaths sound
- less crackle
- improve chest x ray
What is another technique use to acompany postural drainage?
Cupping - a form of percussion technique for chest physiotherapy
How does it assist postural drainage?
use rhythmic shaking motion with cupping technique over affected area to loosen up the secretion
or using a mechanical device (palm cup percussors)
What is the cupping movement
1) Hand position 3 inches from chest
2) strike the chest in waving movement
What is the precautions for cupping
- -> dont do it on bony or breast tissue
- ->dont do it on people with bone problem like osteoporosis
- ->dont do it on people with thorax surgery or fracture ribs
What is the contraindication of cupping
Bone cancer Unstable angina Arrhythmias Skin graft Open wounds Bronchospasm
What is chest vibration
1) its vibration done using both hands during expiration
2) mehanical devices
What are some vibration devices
Thairapy vest
- a high frequency chest wall compression
- small volumes moving in and out of the vest to create the oscillatory motions ( 5 - 25 hz)
- use for 30 minutes
Flutter valve
- pep therapy
- acepella
Disadvantage of the thairpy vest
expensive and cumbersome
What are the types of cough
- acute
- chronic
- paroxysmal
- barking
- dry/hacking
- productive
- cough in the morning
- coughing with positional changes
What cause acute cough
- -> sudden onset
- ->short course
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
What cause paroxysmal?
- ->periodic
- —frequent and violent coughing
- ->prolonged
- ->due to asthma, aspiration, left heart failure
What cause barking
- seal like cough
- croup
- ->swelling and narrowing in the voice box
