ch16 (respiratory emergencies) Flashcards
dyspnea
difficulty breathing/shortness of breath
respiration
exchange of oxygen for CO2
why co2 in the blood necessary?
1.stimulates breathing
2. helps maintain pH level
normal breathing rate for adults
12-20 breaths/min
normal breathing rate for children
15-30 breaths/min
normal breathing rate for infants
30-60 breaths/min
carbon dioxide retention
high blood level of co2 where the respiratory center no longer responds to high blood levels of co2
ventilation
exchange of air between the lungs and environment
hypoxic drive
low levels of oxygen in the blood stimulate the respiratory drive
hypoxia
body’s cells and tissues do not get enough oxygen
atelectasis
collapse of alveolar air spaces in the lungs
bronchitis
chronic inflammation of the lung that may damage lung tissue
orthopnea
severe dyspnea experienced when lying down and relieved when sitting up
paroxysmal nocturnal dyspnea
severe shortness of breath; especially at night after lying down, person is forced to sit up to breathe
diphtheria
infectious disease where a lining forms in the larynx obstruct the passage of air into it
oxygenation
delivering oxygen to the blood by diffusion from the alveoli following inhalation into the lungs
croup
caused by inflammation and swelling of the pharynx, larynx, and trachea
-acute viral infection of the upper respiratory tract seen in children between 6 months and 3 yrs
what are hallmark signs of croup?
stridor and a seal-bark cough
epiglottitis
bacterial infection; inflammation of the epiglottis
-mainly occurs in infants and children
what are some signs of epiglottitis?
tripod position and drooling; stridor
respiratory syncytial virus (RSV)
infection in the lungs and breathing passages and can lead to other serious illnesses
-highly contagious spreads through droplets
bronchiolitis
respiratory illness caused by RSV; severe inflammation of the bronchioles
-occurs most frequently in newborns and toddlers
pneumonia
infection of the lungs (secondary infection)
pertussis
-whooping cough
-airborne bacterial infection that affects children under 6 yrs
influenza type A
animal respiratory disease that has mutated to affect humans
-transmitted by direct contact
