2. Hypoxia What is hypoxia and what can happen with prolonged hypoxia?
Hypoxia is the physical condition induced by an inadequate concentration of oxygen in the blood and the vital organs.
The insidious danger of hypoxia is the subject's unawareness of his deteriorating faculties which may actually be perceived as a feeling of well-being or euphoria.
Exposure to severe hypoxia will result in unconsciousness. Note: there is a wide variability in individual tolerance.
Level of fitness or age does not determine ones tolerance

3. BREATHING AIR SAFETY POINTS
Read this literature carefully as your life and the lives of others depends on correct handling procedures
Oxygen under high pressure in the presence of organic compounds can cause spontaneous combustion.
If oil or grease contaminated fitting and threads come in contact with oxygen under high pressure there may be an explosion
This includes sunburn cream, skin grease, cooking oils.
All equipment must be clean and free of dust
Cleaning is carried out using alcohol solvents and then allow all components to dry thoroughly. There are special solvents & procedures available.

4. BREATHING AIR SAFETY POINTS (continued)
All components must be stored in clean sealed plastic bags in the plastic case located in the canteen.
Always store MH cylinders in their protective bags, full and in a cool area.
Only endorsed members may operate club MH EDS units.
Oxygen cylinders can be filled by members who are endorsed.
Only approved breathing oxygen cylinders that comply with Australian Standards and are in current test can be filled. (5 yrs composite) (10 yr Aluminium)
Use only Dry Aviation Breathing Oxygen BOC Code 430 / RAAF Spec G172

11. Using Oxygen
Check:
Cylinder – security, sufficient contents, turned ON 3 turns, gauge visible.
Plumbing – lines correctly attached, secured and not pinched
Battery in unit and working. A spare battery and jack should be carried in an inside pocket. Battery effected by low temp. Not a requirement at >14,000 ft
EDS Unit connected to O2 supply and to nasal cannula or mask – fit mask/cannula prior to take off.
Check operation before commencing flying

12. Settings
The EDS unit has four different flow rate settings. These provide different O2 flow rates for a variety of conditions and personal requirements N
D5, D10, D12
F10, F15, F20, F25
R/M
July 2013
Ian Cook

13. “N” Settings ‘N’ settings: Night or Now Mode:
Responds to breathing actions at all altitudes with standard delivery protocols.
“Set and fly”.
Flow commences at your starting altitude, at a equivalent rate of 1 10,000 ft
Flow increases automatically with height
Recommended that all pilots use this setting for the majority of flights.
July 2013
Ian Cook

14. “D” Setting Day or Delayed Mode Setting available ‘D5, D10, D12
The EDS unit does not start delivering O2 till you reach the preselected pressure altitude setting.
D5 - commences at 5,000ft
D10 – commences at 10,000ft
On D12 the unit does not start delivering O2 till a pressure altitude of 12,000’ is reached.
Flow rate of equivalent to 1.2 L/m
Recommended that you use the D5 setting
Flow increases automatically with height
July 2013
Ian Cook

15. “F” Setting F settings to be used with face mask
‘F’ settings: Floor or Mask
Settings ‘F10,F15, F20,F25
Each settings cause the EDS unit to ADD additional O2 equivalent to the indicated setting.’
Setting F10
At 8000’ the effective flow rate is 0.8 L/m L/m =1.8 L/m
Setting ‘F20’
At 4000’ you receive 0.4 L/m L/m =2.4 L/m
F settings to be used with face mask
Useful if a smoker or have a respiratory condition
Flow increases automatically with height
July 2013
Ian Cook

16. R/M Setting ‘R/M’ settings: Reserve / Manual
This setting causes the EDS unit to respond to breathing actions with a fixed pulse length of 1/2 sec, regardless of pressure altitude.
Equates to 100% O2 for conventional systems .
Effective flow rate of 10 L/m.
Used as an emergency setting and allows deep inspiration breathing and maximum absorption.

19. Never try to change from a cannula to mask at above 10,000ft
Mask Operation
Pull elastic both sides to snug fit
Press nose clip to fit
Place elastic above ears
Never try to change from a cannula to mask at above 10,000ft
Only mask above with EDS 1
(FAA STD)

20. Alarms The EDS unit has audio and visual (red LED) alarms. Flow fault
Pinched line to EDS unit. (Personal experience line pinched on undercarriage lever)
O2 supply removed
Battery power to low to activate valves. (Go to R/M setting)
APNOEA Alarm
Quite breathing for 45 sec
Outlet Cannula disconnected
Outlet Cannula tube pinched

Ian Cook

21. Using Oxygen
Above 18,000ft FAA recommend full mask rather than just nasal prongs. *See note 1
MUST be on by 10,000ft ‘GFA requirement’
MUST trigger oxygen with each breath – this usually means breathe IN through nose
Alarms sounds if 45 seconds elapse without breathing through nose, oxygen supply run out, battery power low, pinched line on HP or LP side or disconnected.

22. You risk hypoxia at altitude!
Using Oxygen
If you have a beard, a good mask seal is difficult or impossible.
Trim very short or remove beard prior to using masks.
“For some of us beards makes us look younger and more dashing (Ladies excepted)”
You risk hypoxia at altitude!
A risk with using a cannula at high altitude is that you may breath through your mouth and you will go hypoxic very quickly.
If using a mask it does not matter if your breath through your mouth or nose

23. Low battery alarm
If Low Battery fault warning LED is on. Insert jack to reserve battery. Check system OK.
If battery fault alarm still on
press to last button position – R/M mode (reserve/manual) – gives half second oxygen pulses.
Airbrakes deployed, undercarriage down, and descend as quickly as safety allows.
Don’t exceed Vne!
This means well below 10,000ft

24. Alarms
If any flow or fault alarms remain on and the fault cannot be diagnosed and fixed within I minute.
press to last button position – R/M mode (reserve/manual) – gives half second oxygen pulses.
Airbrakes deployed, undercarriage down, and descend as quickly as safety allows.
Don’t exceed Vne!
This means well below 10,000ft

25. Summary
Recommended to use the ‘N’ setting & use oxygen on all flights except local or low altitude. If older, respiratory problems etc. use “F” settings Regularly Check your Oxygen system and know its functions. “It is your life that you may be putting at risk”.

27. CO-PILO2T Kit The CO-PILOT oxygen system is a small, light-weight, hand-held oxygen system. Precision manufactured in Japan, this unit was especially designed for supplemental breathing while at high altitudes. The regulator has an on/off and volume control knob adjustable from off to a max setting of 2-ltr./min. The removable face mask can be replaced by an optional Oxymizer cannula for continuous "hands off" operation. Each 18 liter replacement cylinder lasts up to 30 minutes at 15,000 ft. The regulator can hold a cylinder for several months without any noticeable drop in pressure. Cylinders
