Cuando buceo, el agua es clara y azul. Me siento seguro, no tengo miedo. A unas treinta metros de profundidad pierdo de vista la superficie. Me encuentro solo en un entorno azul oscuro en el que difícilmente distingo el fondo. Luego lo descubro y me siento a salvo. Hay una relativa claridad porque la luz se refleja. Jacques-Yves Cousteau. Entrevista con Perry Miller publicada en Life, 27 noviembre de 1950. En: Violet B. Cousteau. Un hombre del mar. Madrid: Temas de Hoy SA, 1993; p.127. 5 PREFACIO EDITORES La provincia de Cádiz dispone de más de 100 kilómetros de costas y playas. La práctica del buceo deportivo se ha incrementado en los últimos años, con la aparición de numerosos clubes y deportistas federados. Ello, unido a los periódicos ejercicios de buceo militar de la Marina española (Núcleo de Buceo de Puntales y Base Naval de Rota), americana (Rota) e inglesa (Gibraltar), junto a las maniobras de la OTAN, incrementan el riesgo de aparición de accidentes subacuáticos. El Hospital General de la Defensa «San Carlos» en San Fernando (Cádiz), es el único público de Andalucía que dispone de unas instalaciones capaces de asumir el tratamiento de los accidentes de buceo y de las patologías subsidiarias de oxígeno a presión. Su servicio de Medicina Subacuática e Hiperbárica (en funcionamiento desde mayo de 2001) es el de referencia para cualquier evento subacuático que ocurra en el litoral, desde Ayamonte hasta Gibraltar, incluyendo militares estadounidenses e ingleses. En este año 2007 se cumplen siete ediciones del Curso del Doctorado sobre Medicina Subacuática e Hiperbárica que, en colaboración con la Universidad de Cádiz, se han desarrollado en nuestro hospital. Este lapso de tiempo es apropiado para el sedimento de unos conocimientos en una disciplina poco conocida, tanto en el ámbito académico universitario como en el público en general, y así se ha decidido publicar un manual en el que se recojan las lecciones impartidas a lo largo de estos años. El objetivo del mismo ha sido su distribución a los alumnos, a los servicios de urgencias hospitalarios y extra-hospitalarios de nuestra comunidad autónoma, y a los servicios clínicos que puedan precisar tratamientos hiperbáricos para sus pacientes, con objeto de difundir esta modalidad terapéutica. Se ha pretendido que los temas estén actualizados y tengan una orientación práctica para los facultativos poco habituados al manejo de estas patologías. Los autores, con una participación totalmente altruista, han sido los profesores de las anteriores ediciones del curso. En este manual se plasma el esfuerzo de un grupo de facultativos y enfermeros que tras una encomiable y desinteresada colaboración han reflejado en muchos casos vivencias personales a lo largo de sus años de experiencia profesional. El reducido mundo de la Medicina Subacuática e Hiperbárica ha condicionado que los que la ejercitan, a base de un continuado contacto, hayan llegado a ser un grupo de amigos con motivaciones comunes. A todos ellos, a la dirección del hospital, a la Universidad de Cádiz, al Club de Buceo Deportivo «Escafandra» del CN Elcano y finalmente al Laboratorio Salvat, patrocinador y divulgador del manual, nuestro más sincero agradecimiento.

  • Mammalian Diving Response
    Science Unit: Living with Oxygen Lesson 2: Oxygen Consumers – Mammalian Diving Response School Year: 2012/2013 Developed for: J.W. Sexsmith Elementary School, Vancouver School District Developed by: Sheila Thornton (scientist); Duncan Kay and Danielle Conrad (teachers) Grade level: Presented to grade 7; appropriate for grades 6 – 7 with age appropriate modifications Duration of lesson: 1 hour and 20 minutes (2 hours is preferable) Objectives 1. Reinforce the basic concepts of hypothesis-driven science. 2. Understand the body’s need for oxygen and what affects the physiology of respiration. 3. Understand the physics of pressure and how this relates to the circulatory system. 4. Learn the basic physiology of the mammalian diving response. 5. Develop and test hypotheses on the mammalian diving response in humans. Background Information The mammalian diving response is a combination of physiological reflexes that occur when an animal initiates a dive. When an animal’s face enters the water and respiration ceases, the heart rate slows down (bradycardia). Blood vessels supplying nonessential organs are constricted, redirecting blood to the oxygen-requiring brain and heart. When the heart supplies fewer organs with blood, it can beat more slowly and still maintain adequate blood pressure to the brain, the most metabolically sensitive organ. Diving bradycardia is an easily measured component of a group of reflexes that together constitute the “diving response.” This response to diving is observed in seals, penguins and whales, but also seen to a lesser degree in humans. Vocabulary Bradycardia: A slower than normal heart rate. The heart usually beats between 60 and 100 times a minute in an adult at rest.

  • Religious Deep Structuresâ•Flunderstanding and Reaching
    Godina: Religious Deep Structures—Understanding and Reaching Secular Peop 111 BOJAN GODINA Religious Deep Structures—Understanding and Reaching Secular People Interdisciplinary Scientific Basis of Religious Deep Structures Regarding the topics “Invisible Religion” (Luckmann 1967), “Implicit Religion” (Thomas 2001), “Religious Emotion” (Beile 1998), “Personality Independent Religious Emotions” (Godina 2003), or even the psychoso- matic significance of a “Positive Spontaneous Relationship with God” (Grossarth-Maticek 1999:110-113), research has been conducted in the past decades largely in the field of sociology, psychology, and even including the area of systemic epidemiology. A precise and interdisciplinary scien- tific presentation for the phenomenon of “religious deep structures” in the human being was provided in detail by me in 2007 at the faculty for Behavioral and Cultural Studies at Heidelberg University in Germany (Godina 2007:69-372) and thus the topic was introduced into scientific dis- cussion. It was shown through these interdisciplinary studies that the me- dia makers and marketing strategists successfully integrate elements of “invisible religion” into their products in order to address the subliminal human religious needs and desires and thus to increase product sales and media consumption. Within the framework of the Adventist Church as an institution in 2009, further scientific evidence for human religious deep structures were delivered in the evangelistic context by the IKU Institute at Friedensau Adventist University in Germany (Godina 2009: 61-172). In the following article, I will refrain from a detailed interdisciplinary scientific justification of the practice and instead will describe an applica- tion that is suitable for evangelistic practice. This article is a modified and advanced version of the evangelistic book Das Atelier (Godina 2009:69-103).

  • Walter Johnson - Ability-Adaptation Squeeze Model.Pdf
    The Ability-Adaptation Squeeze Model First published 26 December 2013 First, let me say that I am not trying to postulate a universal theory of everything. I am merely trying to get us to a model which is valid to the extent that it is useful and suggests productive avenues of improvement in our thought processes, training, and tactics. I will be making some generalizations, as that is the nature of models, but rest assured, I am aware that no model can possibly account for all the variables that present themselves on even one dive. Still, I feel that this model will be useful, because I think it brings a bit of a useful focus to the recent events that have traumatized all of us. Definitions “Ability” as it relates to a particular dive broadly covers the skills that to some extent at least, can be learned. These skills might include such things as diet, preparation, breathe-up, duck-dive, breath-hold, relaxation, stroke, streamline position, equalization, turn, surfacing, surface protocol, and psychological factors. Certainly, this list is not all inclusive, as there are other skills involved, but I think you get the idea here - you go to school, you learn the skills. Also, I do understand that breath-hold seems to be a difficult fit here, but in the end, as you look at the yin and the yang of it, I think it makes somewhat more sense. The reason for that, I think, is that all the other skills relate so integrally to the breath-hold that it is impossible to separate it from the pack.

    Confirmatory factor analysis of Mystical Experience in Freediving as a recreative way to higher efficiency in sport performance and planet saving and money making Olga Mitina (1), Mir Mirsaidov (1), [ Natalia Molchanova ] (2), Andy Tutrin (2)(*) (1) Faculty of Psychology, Lomonosov Moscow State University, Moscow, 125009, Russia (2) Freediving Federation, Moscow, 119330, Russia (*) corresponding author, email: tutrin(at)gmail.com Preprint DOI: 10.31234/osf.io/b7mnz DRAFT preprint Abstract: searching what and how, and results Aim Investigate accounts from breath-holding freedivers about high efficiency in coping with adversity and pain. Investigate rumors of immediately quitting addictions, attaining harmonious meaningful life, becoming perspicacious and compassionate, getting a spontaneous religious experience. The aim of this research was to investigate such allegations, and if confirmed, to verify would freediving be useful to improve happiness and efficiency in sustainable business money-making. Roadmap = Self-experimenting with feelings during CO2- and O2-assisted freediving to test the technique from Ladislas Meduna (i.e. CO2-and-O2-enriched breathing). Indeed high partial pressure of endogenous CO2 in deep-water hypercapnia is translated into a similar to a high concentration of CO2 in Meduna mix at atmospheric pressure, and anecdotal freediving reports have similarities with mystical experience in the scientific meaning of the word. = Persuade major world champions of deepwater freediving to endorse an anonymous online Mystical Experience Questionnaire MEQ30 survey of freedivers, to check for mystical experiences. = Collect enough anonymous data from freedivers for a Confirmatory Factor Analysis of mystical experience. = If mystical experience is confirmed, conduct a second round of online data collection from freedivers about their personality, experience, happiness, performance in sport and business, etc.

  • Man V Seal: How We Compare with Our Marine Cousins
    Sections Man v seal: How we compare with our marine cousins By Victoria Gill Science reporter, BBC News 17 June 2013 Science & Environment Scientists from the University of Liverpool have published research that explains how marine mammals, including seals and whales, hold their breath for so long. The research reveals how the oxygen-storing capacity of mammals muscles has been changed by millions of years of evolution. The videos above show how a highly trained free-diver compares in breath-holding ability to a common seal. And here we explore some of the most extreme examples of breath-holding in the animal kingdom and how they match up with record-breaking human free-divers. Common yet extraordinary Common seals, featured in the video above, are widespread and familiar, especially in the waters of the north Atlantic and north Pacific Oceans. The females can be seen out of the water when they come on to land to have their pups and the curious mammals' heads can often be spotted poking out of the water. But they spend 80% of their time underwater. These seals can dive for about 30 minutes and even sleep under the water. Their nervous system has an automatic shut-off mechanism that prevents them from breathing at inappropriate times. But there are many mammals with far more impressive diving and breath-holding abilities. Squid-eating giant Along with the beaked whale, the sperm whale is one of nature's best divers. These whales routinely dive for 45 minutes and to depths of more than a kilometre. This enables them to hunt the giant squid they eat.

Plants experience low oxygen levels in many occasions one of which is flooding. Interestingly, both plants and humans have similar solutions to deal with the challenging environment under water. Humans came up with many ways to explore the extraordinary underwater life; one of the easiest and cheapest ways being breathing through a snorkel.
