lecture 11: thoraic injuries Flashcards
3 main groups in chest cavity
pulmonary
vascular
gi tract
where is the scapular
ribs 2-7
spine at t3
where is the lung apex
2.5 cm above clav
where is the coracoid process
lines up w first rub
where is the nipple
level of rib 4
where is the heard
level of hibs 2-6
what are the most commonly injured ribs
5-10
what are the true ribs
1-7
what are teh faslse ribs
8-10
what are the floating ribs
11-12
explain the breathing mecahsism
exhalation: pressure is postive and gases are forced out
inhialtion: oressure in neg so air comes in
what nervers supplies diagphram
phrenic nerve (c345)
if there is an injury to c3 orn above what happens
cannot breath
when diagprah contacts andx relaxewhat happens
chest cavity enlarges reducing pressure (asir rushes in )
then disgaphrm revalxes and pushed out air
if thre is an increase in co2 what happens to breathing rate
increase
chest injuries that go unrecognized can lead to…
1) tissue hypozia
2) hypercarbia (increase co2)
3) acidosis
what is assessment for thoraic injuries
uabcs secondary assessment (observe, palpate, asuticulate, percussion) bitals treatment decision
what ar some observations to look out for
bruses
cyanosis
vein distensioin
open chest wounds
is tracheal deviation an early or late sign
late sign
true ro false: trachean should move inferior on inspiration
true
when you are palmpating you are looking for
tenderness deformtity swelling crepitus emphysema
what si the respiotry breathing assessment
rate deptjh rythm sounds other diagnostic sounds
what is the treatment for anything that affects airway exhange and oxygenation
improve oxygenation and transport rapid
what is the treatment for a major problem that is blood losss
imporove oxygen
shock
rapid transport
whta are some respirtry problems involving blood loss
hemothorax, shear to aorta
athletes with mild contusion may RTp after how long
15 minutes
what are the conditoons for return to play
vitals normal
no pain (refered or interfer)
protection
no respisration alterantion
true or false: respitory distress deveols more rapidly in adults
false in children
