AVIATION MEDICINE Flashcards
Definition of Hypoxia
Lack of oxygen in the blood tissues
Management of Hypoxia?
Give oxygen- 4L
Calm and reassure
make comfortable by loosing clothing
monitor
Symptoms of Hypoxia?
MILD
fatigue
lack of concentration
listlessness
MODERATE
breathlessness
mood swings
confusion
lack of criticism
SEVERE
death
unconsciousness
cyanosis
Decompression sickness definition?
When gas bubbles form
due to atmospheric pressure
e.g diving, need 24hrs for nitrogen to release
cabin crew- 48hrs
Symptoms of Decompression sickness?
the bends
the chokes
the creeps
In detail..
Symptoms for decompression sickness
deep pain in joints
difficulty breathing
odd sensation in skin
red rash
partial loss of vision
How to manage Decompression Sickness?
Let the FD know
to divert to nearest airport with a hyperbaric chamber
to descend to a lower altitude to release nitrogen
unconscious- lay in recovery position
conscious- lay them on their backs with feet up
keep warm
restrict movement
give oxygen
monitor
Depressurisation types?
Gradual
Rapid
Symptoms of Graduel depressurisation
Headaches
mild euphoria
sleepiness
drowsiness
increase pulse rate
Symptoms of Rapid depressurisation?
Loud bang
extreme noise
extreme cold
air rushing out
loose items
hot water boiling
Definition of Rapid depressurisation?
Structural damage
fuselage damage
damage to the aircraft system
TUC 20000 FT?
5-10M
TUC 25000FT?
2-3 M
TUC 30000FT?
45-75 SECS
TUC 35000FT?
30-45 SECS
TUC 40000FT?
20-30 SECS
TUC 45000FT?
15-20 SECS
How does it vary?
TUC
due to age
condition of health
fitness
altitude
depressurisation response?
what PA will you hear from the FD
ATTENTION! EMERGENCY DESCENT!
safe altitude reached?
What PA will you hear from the Flight deck?
CABIN CREW safe altitude reached?
Emergency decent response
after hearing the PA what will you do?
FIT- oxygen
SIT- secure in seat wherever
ADVISE- pax to do the same
safe altitude response
after PA has been made what will you do?
TRANSFER- to portable oxygen
ASSIST- crew/pax/administer FA
ASSESS- pax/ identify injuries &dmage to aircraft
report- injuries and damage to aircraft. actions / TEST
When can you stop giving first aid?
When a medical personnel takes over
when the person becomes better
when it becomes unsafe
or when you can no longer continue due to fatigue
Can you contact flight deck for a medical emergency during no contact
no only if a person tries to open the exits or there is a self sustaining fire
what about in limited contact?
What things are you able to contact THE FD during this time?
Yes, for medical emergencies
fuel leak, fire etc i can
first aid role?
Preserve- administer correct first aid
Promote- ongoing treatment
Prevent- further danger
Atmospheric pressure percentage?
78% nitrogen 20% oxygen 2% carbon dioxide
What happens with increasing altitude?
temperature drops
humidity falls
gas trapped in the body expands
atmospheric pressure increases
Pain in Ears management ADULT
Instruct pax to chew and yawn
if that fails then we are going to ask them to take a deep breath, close mouth and noise and swallow
if the pains persists during descent we will give Panadol as instructed by pax
apply warmth to the outer ear and advise to see a medical doctor
Pain in ears Infant
what wil you let the baby do?
let the baby cry vigorously and advise the parents to let the baby suck on a bottle
if pain persists advise to see a medical doctor
Teeth Management?

give panadol
Symptoms of teeth pain?
Hollow Cavity
Decay
gas expanding and putting pressure
Sinus Management?
instruct pax to blow forcibly one nostril at a time
give Bren-Clear
give Panadol
Symptoms of Sinus issues?
Headaches
Pressure in forehead
Watery Eyes
Hyperventilation Symptoms?
feelings
Anxiety
Stress
Rapid or deep breathing
Low level of carbon dioxide
Tingling
Spasms
Fainting
Numbness
Hyperventilation Management?
what to do after you see someone hyperventalating?
