exemple 292 Pain in the joints.

Question 132-17 : The type of hypoxia, which occurs at altitude is a explained by ?

Dalton's law.

.dalton's law tells us that the total pressure of any mixture of gases with constant temperature and volume is the sum of the individual pressures also called partial pressure of each gas in the mixture. also, partial pressure of each gas is proportional to that gas's percentage of the total mixture. because the percentage of oxygen in the atmosphere remains constant at 21%, dalton's law lets us calculate the partial pressure of the oxygen in the atmosphere at any altitude...the human body is affected by the pressure of the gases in the atmosphere. the partial pressure of oxygen and to a lesser extent other gases available in the surrounding air is important in determining the onset and severity of hypoxia. exemple 296 Dalton's law.

exemple 300 It competes with oxygen in its union with haemoglobin.

A reduction of carbon dioxide in the blood.

Franck.when you hyperventilate you loose carbon dioxide from the lungs the way to treat it is to breath into a paper bag to breath back the carbon dioxide you're exhaling and to calm down exemple 304 A reduction of carbon dioxide in the blood.

exemple 340 Inner ear.

Question 132-29 : The coriolis effect in spatial disorientation occurs as a result of ?

Simultaneous stimulation of several semicircular canals.

.coriolis illusion effect the illusion of rotation or movement in an entirely different axis, caused by an abrupt head movement, while in a prolonged constant rate turn that has ceased to stimulate the brain s motion sensing system. this involves the simultaneous stimulation of two semicircular canals and is associated with a sudden tilting forward or backwards of the pilot's head while the aircraft is turning. this can occur when tilting the head down to look at an approach chart or to write on the knee pad , or up to look at an overhead instrument or switch or sideways. this can produce an overpowering sensation that the aircraft is rolling, pitching, and yawing all at the same time, which can be compared with the sensation of rolling down a hillside. this illusion can make the pilot quickly become disoriented and lose control of the aircraft. exemple 344 Simultaneous stimulation of several semicircular canals.

Question 132-35 : The physiological rhythms of a pilot in a new time zone will resynchronise to this new time zone at a rate of about ?

1 1.5 hours a day.

It takes about a day to shift one time zone..the internal circadian clock adapts slowly to abrupt changes of time cues. the rate of adaptation has been reported to follow a number of models. rates of one hour per day without countermeasures, or quicker adaptation during the first days have all been quoted. however, since the adaptation is highly dependent on the individual, to the direction of flight, to the number of time zones crossed, to exposure to environmental cues any simplistic formula is inappropriate..the direction of the time zone change is particularly important. in general adaptation after eastbound travel is much slower than after westbound flight..example during summer, after a flight from london to kuala lumpur malaysia , the time change is 7h. it will take 7 to 10 days to acclimate to the new time zone. exemple 368 1 - 1.5 hours a day.

Question 132-36 : The duration of a period of sleep is governed primarily by ?

The point within your circadian rhythm at which you try to sleep.

.the timing of adult sleep is governed by circadian rhythms physiological changes that follow a 24 hour cycle. many of these changes are influenced by your exposure to light...when you expose yourself to sunlight each morning, you help maintain your internal clock. even if you are sleep deprived, morning light exposure helps ensure that you will be more alert during the day than you are at night. as the day wears on and darkness falls, your body begins to produce less cortisol a hormone that keeps you alert and more melatonin the hormone of drowsiness. when you expose yourself to bright, artificial lighting in the evening particularly to lights that include the blue part of the spectrum you delay these changes and may find it harder to fall asleep. exemple 372 The point within your circadian rhythm at which you try to sleep.
