compare symptom and sign
symptom - from patient; subjective
signs - from PT; objective measures/tests
what is tidal volume
amount of air a person inhales and exhales at rest
500-700 ml
what is inspiratory reserve volume
amount of air a person can maximally inspire at end of normal respiration
~2 L
what is expiratory reserve volume
amount of air a person can maximally exhale at end of normal exhalation
~1 L
what is vital capacity
IRV + TV + ERV
amount of air a person can take in and out of lungs
~3.5 L
what is residual volume
air that stays in lungs after ERV
~1.3 L
what is total lung capacity
VC + RV
~5 L
discuss eupnea
normal, regular and comfortable
12-20 cpm
younger and athletes have lower
tachypnea
normal to abnormal
> 20 cpm
can be exercise or disease
bradypnea
< 12 cpm, slow
cam be electrolyte imbalance, obesity, hormonal
hyperpnea
hyperventilation c deep breathing
form of tachypnea but deeper
> 20 cpm
can be neuro, psych, metabolic, diseases

damage to medulla
ataxic
disorganization c irreg and varying depths
poorest prognosis
