Module 5a Discussion Flashcards
geriatrics airway considerations regarding c spine
osteoporosis and kyphosis may pose a challenge to applying the C-collar and also increase risk of bone breaks
4 differences in geriatric airway precaution
dentures pose risk for choking
dry mouth - increase risk of inefeciton, choking ability to speak
what are two airway problems that put geriatric patients at risk for aspirations
decreased cough reflex
decreased peristalsis
regarding breathing how do geriatrics respond to increaed oxygen demand
less sensitive to changes in demand –> become SOB with little exertion
what happens to old people alveoli
stretched out
what happens with old peopels chemoreceptors regarding breathing
less sensitive to hypoxia and hyerpcapnia
what happens with cilia in old people
less cilia line trachea –> decreased immunity
What happensto chest compliance in old people
becomes less compliant and loss of eleastic recoil
what does kyhosis and scoliosis do regarding breathing
more dead space and decreased expiratory flow
what happens to coronary blood flow at age 65
35% reduction due to left ventricle and left atrial enlargement –> can cause dysrthmias
what happens to heart contraction in older people
prlonged due to slow release of calcium during systole - decrease CO by 1% a year
what happens to insulin sensitivity in old age
increased
what happens to brain in old age
brain shrinkage
temperature
decreased in old people a normal persons low grade fever whould actually be a high fever in geriatrics
airway differences in children
less than 3 put a towel for sniffing posisiton
narrow nasal passages –> obstruction
infants under 6 nonths are nose breathers
large tongues higher risk of obstruction
