What is the main cause of hypoxic hypoxia for pilots?

• Decrease in oxygen percentage in the atmosphere

• Reduction of air pressure with an increase in altitude

• Chemical inability of blood to transport oxygen

• Excessive acceleration of gravity

What is the primary danger of carbon monoxide poisoning for pilots?

• It causes rapid dehydration

• It reduces the blood's ability to carry oxygen

• It causes spatial disorientation

• It increases blood pressure

What is the term for hypoxia that is caused by reduced ability of the blood to carry oxygen?

• stagnant hypoxia

• hypoxic hypoxia

• hypemic hypoxia

• histotoxic hypoxia

What is the primary function of the vestibular system?

• Controlling breathing rate

• Enhancing night vision

• Maintaining balance and spatial orientation

• Regulating blood pressure

What are common symptoms of hypoxia?

• Excessive sweating
• Muscle spasms, hot and cold sensations, general discomfort

• Nausea, paleness, vomiting

• Cyanosis, impaired judgement, drowsiness

What is the treatment for hypoxia during flight?

• Restoring proper carbon dioxide levels in the body

• Flying at lower altitudes and using supplemental oxygen

• Breathing into a paper bag or talking aloud

• Pinching nostrils and blowing slowly

What is the term for the inability of cells to effectively use oxygen even when it is transported to them?

• Stagnant hypoxia

• Hypemic hypoxia

• Histotoxic hypoxia

• Hypoxic hypoxia

What are the symptoms of hyperventilation?

• Hot and cold sensations, vomiting

• Nausea, paleness, sweating, general discomfort

• Visual impairment, dizziness, tingling sensations, muscle spasms

What is the term for the condition where pressure builds up in the ears and sinuses during climbs and descents?

• Hypoxia

• Middle ear and sinus problems

• Spatial disorientation
