Helping passengers with neurological symptoms Medical Advisory Neurological diseases are disorders of the brain, spinal cord and nerves. When something happens to your nervous system, you can have trouble moving, speaking, swallowing, breathing or learning. You can also have problems with your memory, senses or mood.
In ight neurological symptoms such as #ainting episodes, dizziness or severe headaches can be di##icult to identi#y correctly 3 sometimes masquerading as an entirely di##erent condition altogether. Consider, #or instance, the alarming incident o# loss o# consciousness. This neurological event can be the result o# several underlying causes, which might be metabolic, such as low blood sugar (hypoglycaemia) or oxygen level; cardiac, such as irregular heart rhythm or ine##icient pumping action; haemodynamic, such as dehydration or blood loss; or traumatic, #rom a head injury.
The loss o# ability to speak ... more. less.
in someone who used to speak normally can be the result o# a stroke or metabolic disorder. Loss o# motor #unction o# a body part can be caused by a stroke or nerve root compression. Conversely, the brain.<br><br> This process may occur in passengers with pre-existing cardiovascular disease and in those passengers su##ering #rom head trauma or a ruptured aneurysm; " head injury 3 #rom a #all or #alling objects #rom overhead bins. I# serious, a head injury may cause loss o# consciousness and/or bleeding in the brain tissue, and; " hyperventilation (breathing unusually rapidly or deeply) 3 anxiety can cause numbness and tingling around the mouth and numbness in fngers and hands. Managing a neurological incident The recommended method o# managing neurological incidents is to: 1.<br><br> Assess the situation. 2. Ask the appropriate questions to the passenger or travelling companion: main symptoms/complaints; has this happened be#ore?; other medical history; current medications and allergies; what has been done so #ar?<br><br> 3. Give the passenger oxygen. 4.<br><br> Stabilise injuries i# present. 5. Initiate communication with land physicians and relay the gathered in#ormation.<br><br> The more in#ormation that telemedicine physicians have at their disposal, the #aster they can determine how to stabilise the passenger and diminish the likelihood o# complications. 22 neurological hyperactivity can cause its own set o# problems in ight 3 resulting in seizures, involuntary movements or panic. While neurological symptoms can vary #rom #ainting episodes to body weakness and speech di#fculties, the seriousness depends on the context o# that person 9s medical history and recent activity.<br><br> By understanding the processes behind the most common in ight neurological scenarios, crew can #eel more confdent in the initial management o# such events until defnitive help becomes available. The most common in ight neurological scenarios are: " weakness 3 generalised weakness is usually metabolic in origin (hypoglycaemia, hypoxia, dehydration), whereas #ocal weakness is neurological; " dizziness 3 also described as lightheadedness, vertigo (a spinning, rocking sensation or #eeling that the environment is moving), unsteadiness (gait problems) or even depression. May be caused by an endocrine disorder, inner ear in ammation, such as labyrinthitis, or stroke; " con#usion 3 causes can be metabolic (low blood sugar), toxic (drugs or medication toxicity/side e##ect) or stroke (depending on the location o# stroke, the predominant symptom may be a change in mental status or a personality change); " headache 3 an extremely common symptom.<br><br> Can be the result o# something as trivial as tension or as serious as a type o# stroke called 8subarachnoid haemorrhage 9; " seizure 3 not necessarily alarming in a passenger with a pre-existing seizure disorder but can be a new onset seizure #rom a metabolic derangement (hypoglycaemia, toxins) or stroke; " stroke 3 the sudden onset o# neurological defcits, such as the inability to move one side o# the body, can result #rom compromised blood ow or haemorrhage (bleeding) in
