Hypoxia
Reduced or not enough oxygen.
What is Hypoxia?
A common way to induce hyperventilation.
What is rapid or excessively deep breathing?
The "popping" of the ear with changes in altitude is caused by the release of pressure in this part of the ear.
What is the middle ear?
CO2 could fill the cabin and starve your body of oxygen if this product is carried in the aircraft.
What is dry ice?
Decompression sickness is associated with this gas causing bubbles in the body.
What is nitrogen?
Hypoxic, hypemic, stagnant, and histotoxic.
What are the four types of Hypoxia?
This hormone, when induced by pain, fear, or anxiety, may increase the breathing rate and contribute to hyperventilation.
What is adrenaline?
Swelling or mucus caused by the common cold can block this pathway, causing trapped air in the ear.
What is the eustachian tube?
Small aircraft heaters that use the exhaust manifold as a heat source could allow this gas into the cabin.
What is CO?
Pilots should wait this long after their last scuba dive prior to flying to minimize the risks of DCS.
What is 24 hours?
The altitude above which the FAA requires pilots use supplemental oxygen immediately.
What is 14,000 ft Pressure Altitude?
Hyperventilation causes too little of this gas to be in the bloodstream.
What is CO2?
If not corrected, a pilot who descends with an ear blockage may rupture this membrane.
What is the eardrum?
Carrying dry ice in a sealed container could result in this type of event.
What is an explosion? [of the sealed container holding the dry ice]
The type of DCS that occurs if bubbles of gas make their way to the joints.
What is the bends?
The condition in which hemoglobin cannot carry oxygen to the body, caused by carbon monoxide.
What is Hypemic Hypoxia?
After controlling breathing, this is the recommended corrective action if a pilot is unsure if the condition is hypoxia or hyperventilation.
What is using supplemental oxygen?
A pilot flying with a head cold or similar ailment might feel pain behind the eyes or nose as the trapped air in this area reacts to changes in atmospheric pressure.
What is the sinus cavity?
This addictive habit can result in self-induced CO poisoning when smoke is inhaled, even secondhand.
What is smoking?
The source of the gas that causes DCS after scuba diving.
What is the compressed air breathed during the dive?
The maximum time a pilot has to make rational, life-saving decisions without supplemental oxygen.
What is Time of Useful Consciousness?
The most common way to recover from hyperventilation, besides controlling breathing rate and breathing into a paper bag.
What is talking out loud?
A pilot experiencing ear or sinus pain during a descent should consider doing this with the airplane to allow the ear or sinus pressures to stabilize before continuing.
What is slow the descent, level off, or climb?
Due to the dangers of this gas, it is common for detectors to be placed in the aircraft cabin in view of the pilot.
What is carbon monoxide (CO)?
A pilot who needs medical attention for DCS may be treated in this device, which enables doctors to control the atmospheric pressure.
What is a hyperbaric chamber?
