Shallow Water Blackout

Sunday, February 8th, 2015

Shallow Water Blackout

Shallow water blackout, the sudden loss of consciousness due to oxygen starvation.

The sudden loss of consciousness due to oxygen starvation

If you’re like most Scuba Divers, what you likely remember about shallow water blackout – the sudden loss of consciousness due to oxygen starvation – is that it happens in shallow water while free diving. But given the growing interest in snorkelling and free diving, especially as a family activity, your working knowledge of this life-threatening malady needs to be more than just a vague memory.

The form of shallow water blackout that most of us are familiar with occurs primarily among breath-hold divers. A common technique when free diving is to hyperventilate before a dive – increasing the rate and depth of respirations. This “blows off” carbon dioxide in the system so that you start the dive with less carbon dioxide in your blood than you would otherwise. This technique allows you to stay down longer because it is elevated carbon dioxide levels in the blood that signal the brain that the body needs to breathe. By starting a breath-hold dive with less carbon dioxide in your blood, it takes you longer to build up carbon dioxide to the point where you feel the urge to breathe.

How Hyperventilation Causes Shallow Water Blackout:
The downside is that hyperventilation can bring on the condition of hypoxia, or lack of oxygen. The partial pressure of oxygen at sea level is .21 atmospheres (ATA). The brain requires a minimum partial pressure of oxygen of .10 ATA in order for you to remain conscious. Hyperventilation can drop you below that level.

Here’s what usually happens:
When a diver hyperventilates to reduce his body’s carbon dioxide level, he also slightly increases his oxygen partial pressure level to around .24 ATA. He then dives to a depth of 33 feet, doubling the pressure he is under, which also doubles the partial pressure of oxygen in his lungs to .48, according to Boyle’s Law. During the dive he extracts oxygen from his lungs, and slowly replaces it with carbon dioxide. By the time carbon dioxide accumulates sufficiently that the diver needs to surface, the oxygen partial pressure in his lungs is .15 ATA, but the diver is still at 33 feet. As he ascends, both he and the gas in his lungs are under less and less pressure, until he reaches the surface where, assuming an oxygen partial pressure of .15 ATA at depth, he would now have an oxygen partial pressure of .075 – less than that needed to maintain consciousness. Therefore, at some point before reaching the surface (usually between 10 and 15 feet), this diver would black out, instantaneously and without warning.

Diving and Snorkelling:

Is It Safe? What are the risks then, if any, of diving after snorkelling, or vice versa? Recreational snorkelling and free diving, because of the relatively short time spent at depth, do not result in any significant nitrogen build up in the blood or tissues. Therefore, there is little to no risk in diving after snorkelling.
However, the reverse is not necessarily true. It is well-known that tiny bubbles appear in many divers’ bloodstreams after diving. These bubbles are usually filtered from the blood as it passes through the lungs without causing any problems.

But if a diver with these micro-bubbles were to dive to a depth where the pressure forced these bubbles back into solution, and then ascend rapidly – as breath-hold divers do – these bubbles would come back out of solution, potentially as much larger bubbles that could result in symptoms of DCS. The depths at which the tiny bubbles would be forced back into solution are variable, but could occur at depths as shallow as 30 feet, well within the range of most snorkelers.

This potential risk can be easily eliminated by avoiding any deep free dives (below 15 feet) after scuba diving. So enjoy your snorkelling surface intervals, but remember to stay close to the surface and to wear a skin or T-shirt to protect your back from the sun.

Padi Open Water Diver Course – Padi Neutral Buoyancy

Tuesday, November 4th, 2014

Padi Neutral Buoyancy -Instructor Development Skills.

Padi Open Water Diver Course – Neutral Buoyancy (Dive 3)

In the Open Water Diver course, Open Water Dive 3 neutral buoyancy skill underwater, the standard states: Become neutrally buoyant and hover by inflating the BCD orally.

The intent of the skill is to ensure that the student diver can use BCD oral inflation to attain neutral buoyancy in open water, as was mastered first in confined water.

You may also conduct this skill by:
1. having student divers demonstrate padi neutral buoyancy via oral BCD inflation (fin pivoting, for example). This demonstrates that the student can use controlled manual inflation underwater in the event of an inflator freeze or malfunction. Once the student is neutrally buoyant, then

2. having the student demonstrate hovering – using either BCD oral inflation, BCD LPI inflation, or dry suit inflation.

This offers a practical option in areas where student divers dive in dry suits that you can use now. The
amendment will be included in future editions of the Padi Open Water Diver Course Instructor Guide, Padi Neutral Buoyancy Skills.

The eRDPML™ in PADI Courses

Tuesday, November 4th, 2014

You’ve heard that the eRDPML is replacing The Wheel and the eRDP, but did you know that your divers can use it to meet all knowledge development and testing requirements for all PADI courses from Open Water Diver to instructor? Here’s a simple guide to how you can use the eRDPML in your courses.

Using the eRDPML in PADI Courses
Student divers can use the eRDPML in all PADI courses to answer Recreational Dive Planner exam questions. Beginning 1 January 2009, all PADI Divemaster and Instructor Development Course candidates – including those only participating in an Assistant Instructor or Open Water Scuba Instructor programs – will be required to have their own eRDPML in addition to the RDP Table version.

PADI Open Water Diver Course
During the PADI Open Water Diver course, student divers may use either the eRDPML or the RDP table to answer questions in Quiz Four and the final exam. If you currently teach multilevel diving using The Wheel in your courses, your divers can now use theeRDPML to answer all RDP questions.

In the future, PADI eLearning participants can choose to learn the eRDPML in Section Four, Section Five and the final exam. Multilevel dive planning is optional and not part of the PADI eLearning assessments.

PADI Divemaster Course
Since the eRDPML has replaced The Wheel and the original eRDP, divemaster candidates can use the eRDPML to answer all questions on the Decompression Theory and The Recreational Dive Planner Exam. You will also want to make sure that candidates understand the RDP Table version so they will be able to answer any student diver questions while assisting with PADI courses.

PADI Instructor Development Course (IDC)
IDC candidates may use the eRDPML to answer questions from the Recreational Dive Planner exams. However, candidates must still demonstrate mastery of the RDP Table version. Candidates should be proficient in both versions and be prepared to teach either version during the IDC.

PADI Instructor Examination
Instructor candidates can use the eRDPML to solve all RDP problems in the dive theory exams. Knowledge Development assignments based on the RDP during the IE will clearly designate whether candidates should teach using the RDP Table version or the eRDPML (or The Wheel through the remainder of 2008).

Please use the eRDPML during any professional diver training courses like Padi Dive Master or Padi Instructor Courses in Cyprus
