for a brief instant in time. right at end of exhallation. lung pressure (alveolar)= environement pressure
what happens with air exchange during resting expiration
no air goes in and no air goes out. happens in an on going fashion. at the end of every breath.
lung volumes: is there ability to influence?
no. anatomically driven. they are what they are
lung volume is...
how much air in the lungs at any given time.
resting tidal volume/tidal breathing: what is it? what does it depend on? factors?
volume of air exchanged during a specific task. depends on task demands: running, talking, sitting. factors: fitess, build, age, gender, size.
resting tidal volume/ tidal breathing serves as a reference point: describe

SB: 10% inhale; 90% exhale
volume of air inhaled per cycle: QB? SB? how much utilized?
QB: inhale up to 50% VC, exhale down to 40% VC. 10%VC utilized

SB: inhale up to 60% VC. exhale down to 35-40% vc. 20-25%VC utilized
loud speech: Same questions
40%VC utilized. need more air: more force: speak louder.
child speech: VC USED? why?
40% vc used. smaller lungs
muscle activity during exhalation: QB? SB?
QB: inhalation active, exhalation passive (recoil forces- muscles must relax after contracting)

SB: controlled exhalation using abdominals
problems that may effect speech: (3)
1. inadequate air supply- in take problems. limited vital capacity
2. inefficent breath control- limited access to vital capacity due to muscular problems
3. loss of air pressure due to inadequate valving (muscle weakness)
Ptrac: air pressure at level of trachea
Poral: air pressure at level of oral cavity
general principles guiding management of respiratory breakdowns: (2)
evaluation of static and dynamic breathing.

management of inhalation and exhalation
why imp to regulate management of inhalation and exhalation? how treat?
if you don't take in enough air, you won't have enough to exhale and will effect speech. individualized nature of treatment. same general format but different.q
management can effect all subsystems: meaning
when working with someone you need to look at the whole picture, family, respiration, communication needs, etc. not just a pair of lungs with limited vital capacity
why do we care about breathing in this course?
1. lungs are beginning pint of whole process.
2.lungs are originating point of generating sound
instrumentation of estimating volumes/capacities of pressures: why want to know this? respiratory therapy?
to see if the person is producing enough air to speak. respiration therapy, want to know capabilities if someone has sustained some damage.
piece of instrumentation used to estimate lung volume
parkinson's disease: location
neurological disease
represents a loss ( of some degree) to muscle control
nature of disorder
muscle rigidity
speech characteristics
articulation-speech sound distortions. lips, tongue, etc. can't hit the proper positions that they once could.
(intonation) flat inflection. absense of appropriate intonation. more monotone quality to voice. imp in pragmatics. and understanding in lang.
laryngeal control
reduiced vocal intensity. hard to comunicate in a restaurant. might end up staying home, embarrasing too hard. can effect social life, confidence, def interupts lief activities.
respiratory control:
chest wall shape (compressed) lead to limited vital capacity. outside layer of pleura is attached to thorax. lungs go for the ride. lungs have reduced room for air. compromised tracheal pressure. comprmised oral pressure- air pressure in mouth
compensatory strategies:
maximize pressure and control egressive air stream(going out)-> in order ot produce speech

- reduced sentence lenght
- frequent inhalation
- speaking at beginning of exhalation cycle
increase vocal intensity
strengthen vocal fold clossure. enhance laryngeal control thorugh sustained vowel phonation. through sustained ( continuant) consonant phonation.
cerebellar disease: nature of problem:
poor coordination of voluntary movement
speech characteristics:
unpredictable pitch and loudness control (laryngeal changes). scanned speech (robotic speech). cannot get louder- prosody question-telling a joke- punch line- ouder- can't do
respiratory function:
tital breathing may be jerky. inspiratory gasps. not smooth, may need more air. vital capacity may be below normal
managment strategies
begin utterance significantly above resting expiratory level (movement where all pressure are equal- no air going in- none going out)
spinal cord injury: nature of problem:
poor/no enervation to muscles
speech characteristics:
reduced vital capacity. reduced vocal intensity (less larynx control) imprecis consonant production. few syllables per breath (can't sustain exhalation) slow inspirations (timing issue) why? muscles lower rib cage- connected to spine- will effect size of thoracic cavity
repiratory function:
vital capacity may be below normal. difficulty accessing IRV, ERV. larger abdominal volumes. will effect size of thoracic cavity
management strategies:
encourage larger lung volumes. facilitate optimal posture/ individuallly adjusted seating system. if you're not sitting right, less room for air. greater volition control-over speech ( muscle strengthening and coordination exercises)
cerebral palsy: nature of damage:
reduced oxygen to brain often druing birth but at any time in life. muscle regidity maybe throughout whole body
speech characteristics:
articulation-distortion (dysarthria) and hyper/hypo nasality. takes muscle control to raise or lower the velum. prosody- flucuations. laryngeal control- pitch.
respiratory function:
smaller than normal vital capacity. muscular problems leading to coordination problems( msucles related to breathing). pressure loss due to poor valve control
management strategies:
postural support to help with vital capacity. abdominal trussing another form of abdominal support. inspiratory checking- take in air in smaller increments
voice problem: nature of problme:
central (neurological) peripheral (damage to actual vocal folds)
speech characteristics:
varied, according to nature and scope of damage. horseness, intensity prob: dif with pitch.
management strategies:
clavicular to abdominal breathing. yawn-sign (for vocal fold hyper function) type of vocal fold excercise.
larynx sits atop the
first tracheal ring

positioned anterior to
C4 through C6 (cervical vertebrae
4 functions of larynx
