Requirements and explanations

Important information

• Oxygen is essential, whether you are 30 minutes offshore or unlimited. Oxygen is FIRST AID not a luxury. See Conditions requiring Oxygen.
• In remote sites (on yachts), you cannot have too much Oxygen. See below for durations of Oxygen supply.
• ALL OMI Class A and B Kits contain Oxygen (4 litres = 800 litres of Oxygen) AS STANDARD
• IMPORTANT. All other suppliers of MCA A and B kits should contain Oxygen as standard and not as an option. Some providers are suggesting optional.
• Oxygen is an integral component of the new OMI Advanced Emergency Grab bag.

Oxygen 4 litre supply (EU = 800 litres, US = approx. 500 litres)

• 2 x 2 litre D size cylinders.
• 2x waterproof barrel bags
• 1x Variable flow regulator with a SCHRADER, secondary outlet as standard (for Diving emergencies, see below).
• A full set of Emergency Oxygen masks (including Paediatric masks), variable Oxygen % masks.
  
• A Pulse Oximeter.
  
• Oxygen use instructions.
  
• Set up and ready to use
  
• Oxygen valve key
  
• Spare regulator seal
• 2nd Variable flow regulator and pulse Oximeter as an option to allow you to have 2 independent Oxygen Kits. This is ideal so
  one system can be used onboard and one available for tender use where many incidents can occur. 
  

Oxygen 2 litre supply (EU = 400 litres, US = approx. 250 litres)

• 1 x 2 litre D size cylinders.
• 2x waterproof barrel bags
• 1x Variable flow regulator with a SCHRADER, secondary outlet as standard (for Diving emergencies, see below).
• A full set of Emergency Oxygen masks (including Paediatric masks), variable Oxygen % masks.
  
• A Pulse Oximeter.
  
• Oxygen use instructions.
  
• Set up and ready to use
  
• Oxygen valve key
  
• Spare regulator seal

Oxygen 10 litre supply (EU = 2000 litres)

• A back up supply because when one needs Oxygen one often needs a prolonged supply.
• Too heavy for portable use but can be used to replace the portable Oxygen in OMI kits as soon as convenient.
• Supplied as a cylinder with a cover. The regulator can be used from the portable OMI supplies unless an extra regulator is requested.

Oxygen and Diving

• When diving is undertaken, Oxygen should always be available.
• High flow Oxygen can deal with many causes of diving problems (such as a
  collapsed lung, or many other conditions). However DECOMPRESSION
  SICKNESS can only be slowed down using 100% Oxygen. This can only be
  provided using Oxygen with a DEMAND OUTLET (SCHRADER) plus a special
  hose and a 100% Demand Mask.
• OMI from September 2011 will supply all regulators with a SCHRADER outlet,
  therefore , simply adding the tubing and Demand mask gives you an
  economical delaying treatment for decompression sickness (until a
  Recompression chamber is accessed).

Dive Oxygen 2 litre supply (EU = 400 litres, US = approx. 250 litres)

• 1 x 2 litre D size cylinders.
• 2x waterproof barrel bags
• 1x Variable flow regulator with a SCHRADER, secondary outlet as standard (for Diving emergencies).
• SCHRADER Armoured tubing with 100% DEMAND Mask.
• A full set of Emergency Oxygen masks (including Paediatric masks), variable Oxygen % masks.
  
• A Pulse Oximeter.
  
• Oxygen use instructions.
  
• Set up and ready to use
  
• Oxygen valve key
  
• Spare regulator seal

Pulse Oximeter

• Pulse Oximeters are provided in most OMI Kits as standard.
• Within seconds they give readout of the percentage of Oxygen carried in the
  person’s blood stream.
• This acts as an immediate indication of the severity of a situation.
• 94‐95% is considered the minimum level for most well people at sea level.
  

So the 1st use of this device is diagnosis of a severe situation. However:‐

• The other use of this device is to regulate and ‘ration’ the supply of your finite Oxygen supply.
• In an emergency e.g. unconsciousness; the flow rate advised would be 15 litres per minute. However using this device under
  medical advice the flow rate may be able to be slowed until the Oxygen % starts to drop.
• The resultant need of the patient may be 2 litres a minute flow (adjustable easily on the standard OMI regulator). Therefore instead of using your 400 litre , D size cylinder at 15 litres minute ( 27 minutes available) ,you may find that 2 litres a minute is all that is required thus giving more than 3 hours of supply!

How much Oxygen might you need

It is easy to appreciate that the relatively economical back up F Size cylinders are well worthwhile investing in.

Regulators

Oxygen is required in almost any medical emergency (or possible emergency) situation. In most situations when the level of oxygen needed is unknown e.g. when you have a breathless or unconscious patient, a variable flow regulator is used at maximum flow along with a non-re-breather oxygen mask (in rare cases lower percentages are required but these are also provided for in OMI kits). This is how the oxygen supply in the OMI Advanced
Emergency Grab Bag is organised. However, the other use of oxygen is related to diving incidents. If there is a suspicion or definite decompression sickness case, the only way of buying time to get the patient to a recompression chamber is by using a 100% oxygen demand system. This is usually supplied from a special regulator, which fits on any pin index cylinder, but has a second outlet. The second outlet can be attached to armoured tubing and connected to a demand mask, which is very much like a standard diving mask. This will deliver oxygen to the patient triggered by their own breathing (but can also be used in people with poor breathing movements). This therefore delivers 100% oxygen to the patient. These special regulators also have variable flow outlets, so they can also be used for standard oxygen use and is the normal use for people who have all standard risks on-board: but also can be used when diving from the vessel.

How much Oxygen?

A simple rule with oxygen in remote areas e.g. on your vessel is that you can never have enough. If something happens that requires oxygen then having adequate supplies is essential. Our standard supply is usually 4 L of pressurised oxygen which gives between 600 to 800 L of actual oxygen. This seems a lot, however in a serious situation with the flow at maximum (15 L per minute); this might only last 40 to 50 min. Of course, using the provided pulse Oximeter (supplied as standard in OMI kits) may allow you to reduce this flow rate and extend the range of the oxygen (ideally under medical advice), but in some serious cases only the maximum flow rate
will do. So it is clear that if you can have more oxygen available is a worthwhile investment. OMI can supply large F size cylinders (1500-2000 L) which can be used as backup supplies and are particularly recommended on vessels that undertake diving because finding a recompression chamber can take a considerable length of time.
The large F sized cylinders are not portable easily; however this is why smaller portable D size cylinders are in your new grab bag and backup oxygen bag.

Where to have Oxygen?

The portable source of easy to use oxygen should always be with your emergencies supplies i.e. in or with your grab bag. This should always arrive at any possible medical situation. The other risky situation is related to most tenders. Tenders are used often as a base for watersports and diving and so a portable oxygen set should usually go into the tender along with either the standard or advanced tender kit. This portable oxygen kit ideally should be one of the ones designed to provide 100% oxygen if diving is being undertaken. By simply adding a second regulator (100% type), 100% oxygen mask and tubing +/- pulse Oximeter to your backup OMI oxygen cylinder you automatically have a fully functional Tender oxygen kit.

Refilling Oxygen/ Oxygen standards

Unfortunately, either side of the Atlantic there are different standards of cylinder and generally is difficult or impossible to refill US cylinders in Europe and vice versa. For this reason vessels that oscillate between either side of the Atlantic, generally choose to have both systems available. This is the most pragmatic solution and allows for refills and standard retesting to be done in both situations and could work to your advantage, should a medical situation occur, and both systems are fully charged this could mean you have more available oxygen.
