Was kann man gegen die F-Tolerance machen
1. Tilt Back Seat => over 45 Grad Tolerance + 2-3 Gz 2. Anti G Trousers + 2G 3. AGSM = Pressen mit der Baumsukelatur => + 2-2,5 GZ
Wie viele UV-Strahlen gibt es ?
UV A: 320-400 mm UV B: 290-320 mm UV C: 200-290 mm
UV C wird absorbiert von
Ozon Schicht Ozon layer
UV A verursacht:
1. skin aging 2. skin cancer => kein Sonnenbrand
UV B verursacht
1. Skin aging (Alterung) 2. sunburn 3. Skin cancer
aging
ALterung
Sunburn was passiert?
DNA damage => cell death
Skin canver durch
UV A und UV B chroniccumulative damage without sunburns and repetitive (wiederholende) sunburns
UV - Radiation Effects on Eye
Snow blindness => UV-B => sunburn of cornea (Augenhaut entzündet sich) => Augen werden rot, tearing, swollen ==> SUNGLAsses
Ozon =>
Headache , irritation of mucous membranes (eye, nose, airways) ==> Prevention Aircraft: ozone monitoring above Fl180 On ground: no excessive activity between 10 am and 4 pm

AT an altitude where teh pressure is half of that at sea level a person will have to:
use supplementary oxygen
A pilot has caught a cold. What may happen to his susceptibility to hypoxia?
it will increase due to the need to generate more oxygen which leads to a greater demand for oxygen
How should decompression sickness be treated if encountered during flight?
Descent to a lower altitude and place the individual on 100% oxygen if available
Whicg law explains partial pressure
Dalton's law
carbon monoxide can be found in higher concentrations in the blood of
smokers
Oxygen absorption by the cells is calles
internal respiration (viscular breathing)
A man who has a high cholesterol level, exposes himself to teh risk of
hear attack
The eardrum separates the x from the y
The eardrum separates the middle ear from the auditory canal
Pressue equalization in the moddle air is made by
the eustachian tube
vertigo
Schwindel
shivering
Schauer
a infected root of a tooth may cause pain
during the climb
An indicatio for a lack of oxygen is
cyanose = blaue Finger
Wieviel breitet sich die Luft in der der Höhe aus?
18'000 fuss doppelt so viel => 34'000 4x mal ==> Sow ie sich der =2 druck abnimmt, nimmt das Volumen zu
Luft Ausdehnung x2 x4 x6 und im Magen ?
18'000ft: 2x Ausdehnung
34'000ft: 4x Ausdehnung
43'000ft: 6x Ausdehnung
Im Magen: 5x auf 34'000 ft
At an altitude where teh presuure is half of that at sea level a person will have to:
use supplementary oxygen
What is the remedy for decompression sickness, or bends?
increase the amount of oxygen
What is considered to be the lowest partial pressure of oxygen, approximately, before performance deterioration begins ?
55 mmHg
Insulin is produced by the pancreas and controls the level of carbohydrate in the blood within very precise limits.
How is the control mechanism for this release monitored?
Neuro-hormonal feedback
How much of the body's available oxygen, under normal conditions, does the brain use...
20%
What term is used to describe the increasing sensitivity of the eyes in low light conditions?
Adaption (or adaptation)
What is the typical human tidal volume?
500 ml
Which Law states that the rate of gas diffusion through a tissue medium is proportional to the tissue area and partial pressures on the 2 sides; and is inversely proportional to the tissue thickness?
Fick's Law
What law may be explained by the formula:
PTOT = P1 + P2 + P3 + P4 etc. ?
Dalton's Law
What is sensitivity?
The lowest threshold at which sense organs respond
