Question 136-15 : Some hours after a rapid decompression at fl 300 you experience pain in the joints which of following answers is correct ?

You should ask for medical advice flight surgeon since this is a symptom of decompression sickness.

1 2 and 3 are correct.

Question 136-17 : Decompression symptoms are caused by ?

Dissolved gases from tissues and fluids of the body.

Decompression sickness describes a condition arising from dissolved gases coming out of solution into bubbles inside the body on depressurisation decompression sickness most commonly refers to a specific type of underwater diving hazard but may be experienced in other depressurisation events such as caisson working or flying in unpressurised aircraftsince bubbles can form in or migrate to any part of the body decompression sickness can produce many symptoms and its effects may vary from joint pain and rashes to paralysis and death individual susceptibility can vary from day to day and different individuals under the same conditions may be affected differently or not at all

Question 136-18 : In the event of rapid decompression the first action for the flight deck crew is ?

Don oxygen masks and ensure oxygen flow.

Question 136-19 : Decompression sickness can be prevented by 1 avoiding cabin altitudes above 18000 ft2 maintaining cabin pressure below 8000 ft when flying at high altitudes3 performing physical exercises before and during the flight4 breathing 100% oxygen for 30 min prior and during the flight ?

1 2 and 4 are correct.

The most satisfactory way to prevent decompression sickness is to avoid exposure to altitudes at which it occurs it does not occur at altitudes below 18&8201 000 feetbreathing 100% oxygen will flush nitrogen from the tissues and the bloodstream this procedure is known as 'pre oxygenation' or 'denitrogenation'

Question 136-20 : Following a rapid decompression at 30000 feet the time of useful consciousness would be about ?

Between 45 seconds and 1 minute 30 seconds.

com encom070 169jpg

Question 136-21 : After a rapid decompression at 35 000 feet the time of useful consciousness is about ?

30 to 90 seconds.

Question 136-22 : After scuba diving more than 30 feet of depth you have to wait a period of time before flying again this period is at least ?

24 hours.

The recommended waiting time before going to flight altitudes of up to 8000 feet is at least 12&8201 h after diving which has not required controlled ascent nondecompression stop diving and at least 24 h after diving which has required controlled ascent decompression stop diving the waiting time before going to flight altitudes above 8000 feet should be at least 24 h after any scuba divethis takes into consideration the risk of decompression of the aircraft during flight

Question 136-23 : Flying immediately after scuba diving involves the risk of getting ?

Decompression sickness without having a decompression.

Question 136-24 : Which statement is correct 1 smokers have a greater chance of suffering from coronary heart disease2 smoking tobacco will raise the individuals physiological altitude during flight3 smokers have a greater chance of contracting lung cancer ?

1 2 and 3 are correct.

Raising the physiological altitude means that the body will think that it is at a higher altitude so if the cabin altitude is 8000 ft the body may act as if it is at 10000 ftthis is due to the reduction in oxygen that the lungs can take in due to all the tar
