DAN Safety Tip: Getting Oxygen First Aid Prepared

9 Apr

danlogoBy DAN Asia-Pacific’s John Lippmann

DAN AP has launched an “Oxygen Preparedness and Awareness” campaign to help instructors and operators in the Asia-Pacific region become better prepared for diving incidents.

As part of this campaign, DAN AP is offering PADI Dive Professionals a 15% Discount* off Oxygen Unit purchases made by April 30.

Let’s look at what oxygen preparedness means and what you need to do to become better prepared.

The importance of DAN AP’s “Oxygen Preparedness and Awareness” campaign is strengthened by evidence that highlights the effectiveness of prompt high-concentration oxygen first aid in helping sick or injured divers.

Oxygen Preparedness means:

  • Having the right equipment readily available;
  • Knowing how to use it; and
  • Having an adequate supply to get a diver to an appropriate treatment facility.

Whilst more operators than ever have O2 equipment and know how to use it, too often they don’t have enough oxygen, which is a problem.

Getting Your Business O2 Prepared

As divers become more safety focused they will begin asking more questions of operators before booking a trip and therefore oxygen preparedness also makes good business sense.

The following steps will help you in determining the oxygen requirements for your business.

Step 1: How Many Oxygen Units Does Your Business Require?

This is determined by:

  • The distance/time from land to the nearest appropriate treatment facility (with more oxygen)
  • The distance/time from the furthest dive site to shore
  • The number of boats in operation

It is also important to have backup oxygen available in case, for example, a unit needs to travel with a diver to a treatment facility, whilst others continue to dive.

Step 2: Make Sure You Have a Sufficient Supply of Oxygen

Dive operators should always plan to ensure that enough oxygen will be available for the expected transport time between the dive site and a suitable medical facility. This may mean many hours or even days in very remote locations. It is important not to stop oxygen breathing too soon. Even if initial symptoms have disappeared with oxygen first aid, they can re-appear later and can worsen substantially.

Step 3: Effective Oxygen Equipment that is Well Maintained

It is commonly believed that because a cylinder contains almost 100% oxygen this equates to a person receiving 100% oxygen when they breathe from the equipment. Unfortunately, this is often far from the truth. The inspired oxygen concentration depends on how much air is taken in (entrained) to dilute what is inhaled. As you can see below, different equipment provides different concentrations of oxygen so it is vital the right equipment is used.

Equipment must be capable of supplying near-100% oxygen to a breathing diver by both:

  • A demand valve; and
  • A non-rebreather mask, with a flow rate of at least 10-15 litres per minute (lpm).

It should also be capable of supplying at least 50% oxygen to a non-breathing diver (e.g. resuscitation mask with oxygen).

Step 4: Make Sure Oxygen is Available at Each Dive Site

All dive operators should have suitable oxygen equipment available at each dive site that is functioning properly and ready to use. Even a delay of 15-20 minutes to oxygen administration can be critical in a severe case of DCI.

Step 5: Staff Trained in Oxygen First Aid

Make sure you have trained staff competent to provide oxygen (as well as first aid and CPR) at each dive site so an injured diver can be quickly assisted.

For maximum benefit, oxygen first aid should be provided as soon as possible after a diving injury and it should not stop unless advised by a dive medical specialist. In the case of DCI, prompt oxygen first aid can help to more quickly reduce the size and of bubbles and so help to minimise the damage they cause.

Step 6: DAN Can Help You

The DAN Team is available to help you implement an effective Oxygen Preparedness Plan that meets your business needs. Email oxygen@danap.org with the following details and you will receive advice regarding the equipment you need to ensure your business is Oxygen Prepared:

  • Your location
  • Distance to the nearest treatment facility (with basic information about this facility)
  • The number of boats you operate
  • The distance (km/time) of each dive site to land.

Don’t miss out on your opportunity to receive 15% Off DAN AP Oxygen Units*.

*Offer is valid until April 30. Freight is additional once the 15% discount has been applied to the product purchase. To redeem the offer please mention “DAN-PADI-O2-Prepared” in your email.
