low level of carbon dioxide in blood, breathig into paper bag would increase level of carbon dioxide
declining PO2 acting on the oxygen sensitive peipheral chemorecepors
hypoxic drive
genetic disorder that produces persistent infection, causes over seretion of mucus that clogs respiratory passages, impairs digestion by clogging pancreatic and bile ducts, sweat glands don't function properly
cystic fibrosis
acute infection and inflammation of lung tissue accompanied by accumulation of fluid (exudation) usually caused by bacteria or virus
amount of air inhaled or exhaled at rest, 500 ml in both sexes
tidal volume
amount of air that can be forcefully inhaled after normal tidal inhalation, 3100 in males, 1900 in females
inspiratory reserve volume
amount of air that canbe forcefully exhaled after normal tidal exhalation, 1200 in males, 700 in females
expiratory reserve volume
amount of air remaining in lungs after forced exhalation, 1200 in males 1100 in females
residual volume
max amt. of air in lugs after maximum inspiratory effort, 6000 in males 4200 in females.
=tidal vol+insiratory reserve vol+expiratory reserve vol.+residual vol
total lung capacity
maximum amt. of air that can be expired after maximum inspiratory effort, 4800 in males, 3100 in females.
=tidal vol+inspiratory reserve vol+expiratory reserve vol
vital capacity
maximum amt of air that can be inspired after normal expiration. 3600 in males 2400 in females
=tidal vol+inspiratory reserve vol
inspiratory capacity
vol of air in lungs after a normal tidal volue expiration. 2400 in males, 1800 in females.
=exiratory reserve vol+residual vol.
functional residual capacity
incomplete formation of palate
cleft palate
inhaling something into lungs, vomt or excessive mucus
when the person drowns in their own fluids
aspiration pneumonia
when nasal septum is so far to one side that it obstructs breathing
deviated septum
mushroom like benign neoplasms of nasal mucosa, may be caused by nasal irritation, may block air flow
nasal polyps
nosebleeds, caused by injury, high bp, leukemia
inability to breath in horizontal position
caused by rapid travel from low to high elevation, headache, shortness of breath, nausea, dizzy, in sever cases can lead to death from pulmonary and cerebral edema
acute mountaion sickness
response to long term change from low to high elevation
deth and rate of breathing are increased, ehance alveolar ventilation, flushes carbon dioxide out of blood, increases ph of blood, dizzy, faint
breathing is slow and shallow
cessation of breathing may occur until carbon dioxide againg stimulates respiration
most widely spread of all respiratiory diseases, many different kinds, no cure
common cold
viral disease that causes inflammation of upper respiratory tract
inflammation of tonsils
inhalation of sute, more common in welders, caused by a build up of particles in alveoli that reduces efficiency of o2 inc HR and leads to heart failure
black lung disease
type of hypoxia, leading cause of death from fire, carbon monoxide is 200 times easier to combine with hemoglobin han oxygen, nove easily detectable
carbon monoxide poisoning
when sand or dust is breathed in to respiratory system sharp particles end up in alveoli, the accumulation results in shortage of o2, heart failure, or particles could rub against alveoli cut them and let blood in overwhelming the system resulting in heart failure
history of smoking, coughing and pulmonary infections are common, develop respiratory failure
chronc obstructive pulmonary disease
difficult or labored breathing, gets progressively more severe
affects persons who are allergic to cats,dogs,roaches,fungi,dust mites, swelling and blocking of lower resp. tubes, panic,coughing,labored breathing,can have long periods with no symptoms
caused by bacterium mycobacterium tuberculosis, 1/3 of pop. infected but most dont develop symptoms:fever,nightsweats,lose weight,severe cough, spitting up blood, treated with antibiotics, have resistant forms of bacterium, can be spread by saliva, resistant form has chronic condtions
inhaled irritants lead to chronic excessive production of mucus, smoking is main cause, air pollution may contribute. inflammation and fibrosis of mucosa in lower respiratory passageways
chronic bronchitis
caused by breakdown of alveoli, from smoking or hereditary, inc. size of air spaces and dec. surface area, inflammation leads to fibrosis and loss of elasticity of lungs, permanent barrel chest due to trapped air in lungs
obstructive emphysema
caused by repeated inhalation of irritating substances such as cigarette smoke. cancers of lip, larynx, and lungs are common in smokers over 50, 1/3 of all deaths from cancer each year in US. more than 90% of patients smoked, care is low, die withing 1 year (7% live 5 yrs)
lung cancer
