ANSWERS | 100% PASS
the gas containing spaces in the human body are at risk for barotrauma
when?
a. only during ascent
b. only during descent
c. only while at depth
d. anytime the pressure is changing - 🧠 ANSWER ✔✔D
Barotrauma Is defined as ? - 🧠 ANSWER ✔✔tissue damage resulting from
a pressure inequality between the environment and a gas filled space
within the body
,your patient has a non -healing planter ulcer. He has had 14 treatments of
the original 20 ordered. Today ,during the chamber pressurization , he
complains of pain in his left ear at 9FSW. the chamber operator stops the
pressurization but the patient is unable to equalize the pressure in the ear.
the chamber operator reduces the pressure in the chamber, stopping at
6FSW and # FSW, but the patient is still unable to equalize. the chamber
operator brings the chamber to the surface , removes the patient form the
chamber, and looks in the ear with a otoscope . He sees a tympanic
membrane that is reddened , and appears to have some fluid behind it in
the middle ear space. this is an example of ?
a. otitis externa
b. otosclerosis
c. otic barotrauma
d. optic barotrauma - 🧠 ANSWER ✔✔(C) otic barotrauma
What is otitis externa? - 🧠 ANSWER ✔✔infection of the outer ear canal
otosclerosis - 🧠 ANSWER ✔✔immobilization of the stapes bone behind the
tympanic membrane this happened over a long period of time and causes
hearing loss, that is not related to barotrauma
, optic barotrauma - 🧠 ANSWER ✔✔is related to the eye usually because of
the scuba mask squeeze
a patient who experiences problems with ears after 15th dive asks why ? if
no problems before and if there is a correlation with the 15th dive - 🧠
ANSWER ✔✔no correlations barotrauma can occur anytime there is
pressure changes , the likelihood is that you are having some swelling in
your Eustachian tube due to allergies or an upper respiratory infection ,
which is the cause of your problem
The most common barotrauma that occurs in hyperbaric environment is? -
🧠 ANSWER ✔✔Middle ear barotrauma
Middle ear barotrauma can usually be avoided with good patient education
and training all of the above are acceptable method of equalizing the
middle ear except - 🧠 ANSWER ✔✔Insertion of chest tube
A Toynbee maneuver - 🧠 ANSWER ✔✔Pinching the nostrils shut while
swallowing
Frenzel maneuver - 🧠 ANSWER ✔✔Pinching the nostrils closed and raise
the back 1/3 of the tongue causing the Adam's apple to elevate sleep me
call this throat piston
