1&2) COPD w/ hyperinflation
3) paradoxical
Expected outcomes of diaphragmatic breathing are __ RR, decr. reliance on accessory muscles of inspiration, __ TV, improvement of dyspnea (subjective), & improved activity tolerance.
1) decreased RR
2) increased TV
Pursed-lip breathing is used to __ RR & __ dysnpea by maintain __ pressure in the bronchioles. This can help prevent airway collapse in pts with __ & help trapped air escape in pts w/ __. Indications include tachypnea & dyspnea. What is the only precaution/CI for pursed-lip breathing?
1) decr. RR
2) decr. dyspnea
3) positive pressure
4) emphysema
5) COPD
6) forcing exhalation
Expected outcomes of pursed-lip breathing include decr. RR & dyspnea, incr. TV & activity tolerance, & prevention of airway collapse in emphysema pts. What are 2 more expected outcomes?
1) Reduce PaCO2
2) Increase SaO2
Segmental breathing is intended to improve __ ventilation & tx pulmonary complications after surgery. The goal is to __ or __ chest wall movement through proper __ placements, verbal cues, or __ of breathing.
1) regional
2&3) facilitate or inhibit
4) hand
5) coordination
Segmental breathing is indicated for __ lung volumes, __ chest wall compliance, & ___ mismatch. What are the precautions/CIs associated with segmental breathing?
1) decreased
2) decreased
3) V/Q
4) NONE but be careful w/ pain/tenderness
Expected outcomes of segmental breathing are increased chest wall __, expand __ alveoli, & ___ loosening+clearance
1) mobility
2) collapsing
3) secretion
What is a very important to aid in airway clearance to help reduce risk of pneumonia?
Hint: Indicated for post-surgical pain, SCI (forced exp. muscles not innervated = T1-T12), & progressive weakness.
Coughing
Compensatory techniques available if pt can’t cough effectively
__/__ stimuli to the __, __, carina, or __ bronchi can cause a cough to be stimulated reflexively.
1&2) mechanical/chemical
3) larynx
4) trachea
5) lower
What are the 5 stages/components of a cough?
1) Deep inhalation
2) Glottis closes
3) Incr. pressure gradient
4) Glottis opens
5) Forceful movement of air
Post-surgical pts may need to splint chest/abdomen by applying pressure over incision w/ pillow or soft blanket roll
If pts cannot perform a directed cough, they can perform a __ cough. This cough is used to force expiration with the glottis open. It does not produce to airflow __ of a directed cough, but it helps decr. risk of __ __.
1) huff
2) velocity
3) airway collapse
Precautions/CIs for coughing are __ precautions w/ inability to control __, __ intracranial pressure, acute __ __, unstable head or neck injury, potential __, untreated pneumothorax, OP, & __ chest.
1&2) droplet precautions w/ inability to control secretions
3) elevated
4) acute MI
5) aspiration
6) flail chest
Name the segment we are working on with this positioning:
Bilateral Posterior Superior Segments
(Specifically Bilateral Superior Segmetns of the Lower Lobes)
Opposite of Bilateral Anterior Segments
flat/neutral
Name the segment we are working on with this positioning:
Bilateral Anterior Segments (lower lobes)
Opposite of bilateral Posterior Segments
lower lobes so 18 in. elevation
Name the segment we are working on with this positioning:
Bilateral Posterior Apical Segments (upper lobe)
Opposite positioning of bilateral anterior apical segments
apical = sitting up
Name the segment we are working on with this positioning:
Left Lingular
Remember: this is the left version of the Right Middle Lobe
Elevated 12 inches only!!!
Name the segment we are working on with this positioning:
Left Lateral Segment (lower lobe)
Opposite of Right lateral
Lower segment so raise 18 inches
Name the segment we are working on with this positioning:
Bilateral Posterior Segments (lower lobes)
Opposite of Bilateral Anterior segments (lower lobes)
elevated 18 inches
Name the segment we are working on with this positioning:
Right Lateral Segment (lower lobe)

___ cycle of breathing technique starts w/ diaphragmatic breathing, then adds thoracic expansion for deep breathing, then a relaxed exhale, then huffs/cough, then ctrlled breathing. Expected outcomes are __ loosening/clearance, improved __, and improved effectiveness of __.
1) Active
2) secretion
3) ventilation
4) cough
main idea is practicing breath ctrl, deep breathing, & huffing/coughing in a cycle to clear chest
__ __ is staged breathing at different lung __ f/b huff/coughs to expectorate sputum. Expected outcomes of the technique include mobilizing secretions by creating __ forces induced by airflow: __ of expiratory flow helps shear secretions from bronchial walls.
1) Autogenic Drainage
2) lung volumes
3) shear forces
4) speed
