17
Q

What type of drug is Blood Pressure Medication?

Examples & side effects?

A

High or low blood pressure can be a reason for disqualification from flying duties. There are some medications that can be taken as a pilot but must be approved.

18
Q

What is hyperventilation?

A

State of over breathing usually brought about by fear, excitement or anxiety. Accompanied by a panicky feeling of suffocation that leads to deep, rapid breathing.
Caused by exhaling too much carbon dioxide.

19
Q

Symptoms of hyperventilation?

A

Light-headedness, dizziness, sweating, rapid heartbeat and tingling or numbness in the hands and feet. Fainting sometimes occurs.
Similar symptoms to hypoxia.

20
Q

How do you treat hyperventilation?

A

Conscious effort to slow down the breathing rate (retaining more carbon dioxide).

21
Q

By 18,000ft what is the atmospheric pressure compared to sea level?

A

Half of that at sea level.

22
Q

During climb in a very high performance unpressurised aircraft or during a rapid decompression, what can happen in relation to pressure in the body?

A

Expansion of gases in the body can cause considerable pain. Large bowel can be vented via the anus however the small bowel cannot be vented and sever pain can result.

23
Q

What are the worst foods/drinks for creating pressure in the body?

A

Fermented drinks such as beer, or vegetables such as cabbage and beans.

24
Q

At 30ft below the surface of water, what is the atmospheric pressure experienced compared to sea level?

A

Twice that of sea level.

25
Q

If pressure is suddenly released by ascending to the surface to quickly during SCUBA diving, what will happen?

A

Nitrogen will come out of the blood solution and cause joints and muscles to give rise to the feeling of stiffness in the joints and rheumatic-like pains in the muscles.
If bubbles form in the spinal cord or brain, tingling sensations or paralysis may occur.
If the diver holds their breath while ascending, the expanding air can rupture the delicate lung tissue forcing air into the blood stream. Rising quickly to the brain, this air-contained blood can cause unconsciousness or death.
This is known as decompression sickness or ‘the bends’.

26
Q

What is the most effective relief for the symptoms of decompression sickness?

A

Recompression by either returning to deep water or within a recompression (hyperbaric) chamber.

27
Q

What altitude while flying can cause the onset of decompression sickness?

A

8000ft.

28
Q

What is the recommended period between SCUBA diving and flying when the dive did not require decompression stops during ascent?

A

4 hours.

29
Q

What is the recommended period between SCUBA diving and flying when the dive required decompression stops during ascent but is less than 4 hours?

A

12 hours.

30
Q

What is the recommended period between SCUBA diving and flying when the dive required decompression stops during ascent and is more than 4 hours?

A

48 hours.

31
Q

How long can alcohol still be found in the blood for after ingestion?

A

14 hours.

32
Q

How long can alcohol still be found in the brain for after ingestion?

A

24 hours.

33
Q

If necessary to take sleeping tablets, what is the recommended period of time before flying?

A

24 hours.

34
Q

Which frequency range does alcohol inhibit the hearing of?

A

Low frequency.
