Aveoli
where 02 and C02 exchange takes place between.
surfactant
keeps aveoli from collapsing
attalactasis
collapse of aveoli
plural cavity
2 layers that protect the lungs
1)viseral plura (inner layer)
2)plerital plura (outter layer)
harring brewer reflex
expiration stress receptors lungs signal respiratory centers via the vagus to stop inspiration
kemoreceptors
normal neroregulatory control of ventilation.
central kemoreceptors
located on serfice of medula ablengada detect changes in ph of cerebral spinal fluid if medula fails pons will take over
prerephrial kemoreceptors
located in arch of aortic body and common carotid artery detect variation of 02 in arterial blood in addtion to changes in arterial carbon dioxide and ph levels
normal respiratory rates
adults 12-20
peds 8-24
infants 40-60
hemoglobin
cell in red blood cells carries 02 and C02 through out body
capnography of an asthma pt looks like?
shark fin
capnography above 45
increase ventilation
capnography below 35
decrease ventilation
harring brewer reflex
prevent over inflation of lungs during large inspiration
pulsus paradoxus
systolic b/p drops blow 10 mmhh with inspiration blood trapped in lungs temporarily seen in copd and paricardial tamponade
tachycardia/bradycardia adults vs peds
tachycardia early sign of hypoxia in adults
bradycardia early sign of hypoxia in children but late sign in adults
kusmals respirations
deep slow or rapid gasping sign of accidosis see in dm ketoaccidosis
cheyne storkes respirations
progressively deeper and faster alternating with slower shallow breathing cerebral cortex or brain stem injury
biots respirations
irregular pattern of rate and volume (cluster breathing) intermittent periods of apnea indicative of intercranial pressure or injury to pons or upper medula
aganol respirations
shallow slow infrequent respiration severe hypoxia of the brain
