Methods to increase Lung Volume Flashcards
1
Q
Increasing Lung Volume
A
- reduces airway resistance and improves ventilation
2
Q
Controlled Mobilization
A
- Most beneficial technique
- Combines upright posture which encourages distribution of air to dependent regions with natural deep breathing but can only be used with pt’s who are able to get out of bed
- Control the level of activity so that the depth of breathing increases just slightly
- Then ask the pt to lean against wall of relax against back of chair to get breath back
- Teach patient to identify feeling of slight breathlessness so they can practice on their own
3
Q
Positioning
A
- most lung volumes are responsive to positioning
4
Q
The ______ and its range of movement are affected by ____, _______ ________, size of _______, _____ and ________.
A
- Diaphragm
- Posture
- Stomach Distension
- Intestines
- Liver
- Obesity
5
Q
What positions increase lung capacity by least to to most
A
- Supine
- Slumped Sitting
- Half Lying
- Side Lying
- Sitting Upright
- Standing
6
Q
Supine
A
- Resting level of diaphragm rises, respiratory excursions are large but lung volumes are decreased
- Due to elevated position of the abdominal organs
(LEAST)
7
Q
Slumped Sitting
A
- Sacral sitting with rounded shoulders
- > Supine sitting
8
Q
Half Lying
A
- Use of head of bed upright, legs straight out
. > Slumped Sitting
9
Q
Side Lying
A
- Inclined towards prone - dome of diaphragm on lower side rises into thorax, abdominal organs fall forward out of the way, allowing increased excursion on lower side; upper side moves little
- > Half Sitting
10
Q
Sitting Upright
A
- Dome of diaphragm is pulled down by abdominal organs = Increased lung capacity
- > Side Lying
11
Q
Standing
A
- BEST for increased lung volume
12
Q
Principles for positioning
A
- Bedridden pt’s should spend time in side-lying, inclined towards prone to free diaphragm from abdominal pressure
- Sitting upright is fine in theory but pt usually gradually assumes a slumped posture which restricts lung volume almost as much as supine
- Techniques to increase volume are relatively ineffective in half lying and should be avoided
- Affected lung should be uppermost in the side lying postion
13
Q
Bedridden pt’s should spend time in _________, ______ ________ _____ to free diaphragm from _________ pressure.
A
- Side lying
- inclined towards prone
- abdominal
14
Q
Sitting _____ is fine in theory, but pt usually gradually assumes a _________ posture which ______ lung volume almost as much as ______.
A
- Upright
- Slumped
- Restricts
- Supine
15
Q
Techniques to increase volume are relatively ______ in _____ ______ and should be ______.
A
- Ineffective
- Half Lying
- Avoided
