21% oxygen (Approximate)

1%

• helium 0.0005%

• argon 0.9%

• neon 0.0018%

• carbon dioxide 0.03

Air (earth’s atmosphere) is composed principally of?

air density also decreases

what will happen to air density as air pressure decreases.

air density decreases

what will happen to air density as air temperature increases.

36,000 ft

Turbine powered aircraft need to operate at approximately __________ to operate efficiently.

Hypoxia

a human aspect when the brain is not getting a sufficient amount of oxygen

Hyperventilation

A human aspect when rapid, deep breathing caused by too much carbon dioxide in the blood.

• Loss of judgement

• Increased breathing rate

• Headache

• Dizziness and lightheadedness

• Tingling in the fingers

• Vision becomes impaired

• Desire to sleep

Hypoxia may result to?

• Symptoms similar to hypoxia

• Hot and cold sensations.

• Nausea

• Unconsciousness

Hyperventilation may result to?

Carbon monoxide poisoning

caused from breathing engine exhaust gases?

• Colorless

• Odorless

• Tasteless

Carbon monoxide gas characteristics?

Liquefying air & Electrolysis of water

2 process to make pure oxygen

Liquefying air

process of boiling off the nitrogen

Electrolysis of water

process Electrically separating the oxygen from the hydrogen

- MIL-O-21749

- MIL-O-27210

2 Types of Aviators breathing oxygen

• must be painted green

• must be marked AVIATORS BREATHING OXYGEN

aviators oxygen must be?

99.5% pure oxygen

0.01% moisture content

According to the Federal Aviation Administration's recommendations, it should consist of at least ______ pure oxygen and have a moisture content of less than _______ .

pulse oximeters

These devices measure the oxygen saturation level of the blood.

gaseous

form of oxygen that is stored in steel cylinders at 1,800 PSI to 2,400 PSI.

Gaseous

Liquid oxygen

Solid oxygen

Mechanically Separated

forms of oxygen ?

stored in steel cylinders at 1,800 PSI to 2,400 PSI

where do gaseous stored ? and at what psi ?

liquid oxygen

- Pale Blue transparent liquid

- Stored at -181 degrees F or below in a Dewar bottle.

-181 degrees F or below in a Dewar bottle

where do liquid oxygen ? and at what degrees?

Solid Oxygen (Oxygen Candle)

that actually MAKES oxygen as it burns.

It's also called a chemical oxygen generator.

sodium chlorate encased in a steel case

where do solid oxygen ?

Mechanically separated

forms of oxygen new procedure.

molecular sieve

Mechanically separated is where air is drawn through a ?

Continuous-flow and Demand Flow.

what are the 2 Systems are often characterized by the type of regulator used to

dispense the oxygen?

Continuous-Flow Systems

• In its simplest form

• allows oxygen to exit the storage tank through a valve and passes it through a regulator/reducer attached to the top of the tank.

Manual continuous-flow regulators & Automatic continuous-flow regulators

types of Continuous-Flow Systems

Manual continuous-flow regulators

are adjusted by the crew as altitude changes.

Automatic continuous-flow regulators

have a built-in aneroid. As the aneroid

expands with altitude, a mechanism allows more oxygen to flow through the regulator to the users.

pressure relief valve

is also typically installed in the system, as is some sort

of filter and a gauge to indicate the amount of oxygen pressure remaining in the storage cylinders.

Demand-Flow Systems

When oxygen is delivered only as the user

inhales, or on demand, it is known as a ?

Crew oxygen cylinder

High-pressure gaseous oxygen is stored safely in the located below the ________________ flight deck in the forward cargo compartment.

System shutoff valve

Oxygen flows from the cylinder up toward the cockpit, passing through the _____________, which allows the system to be manually opened or isolated.

Distribution Line

The main supply line splits into separate plumbing legs to feed each crew member station in the flight deck simultaneously.

Mask/regulator

•Low/intermediate pressure oxygen reaches the individual ____________ units housed at each crew station (Captain, First Officer, and Jump seat Observers) for immediate use during emergency depressurization or smoke/toxic fume protection.
