  1. 1. The human diving response - effects of temperature and training

    University dissertation from Lund : Grahn

    Author : Erika Schagatay; Mittuniversitetet.; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Organism biology; NATURVETENSKAP Biologi Organismbiologi; INTERDISCIPLINARY RESEARCH AREAS Sports; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN Idrott; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; The human diving response - effects of temperature and training.; Djurfysiologi; pig; human; training; breath-holding time; breaking point; cold-receptors; arterial blood; vasoconstriction; bradycardia; diving reflex; diving response; Breath-hold diving; Animal physiology; simulated diving;

    Abstract : The aim was to elucidate the cardiovascular response associated with breath-hold diving, especially the effects of temperature in its elicitation and the effects of different types of training on the human diving response (DR) and breath-holding time (BHT), and to evaluate the human DR in a mammalian perspective. A model for simulated diving by apnea and facial immersion in cold water was developed. READ MORE

  2. 2. Cardiovascular and respiratory effects of apnea in humans

    University dissertation from Animal Physiology

    Author : Johan Andersson; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lung volume; breath-hold diving; Apnea; breath-holding; face immersion; cold stimulation; diving response; diving reflex; circulation; bradycardia; vasoconstriction; arterial blood pressure; cardiac output; spleen; respiration; splenic contraction; alveol; Physiology; Fysiologi; Respiratory system; Andningsorganen; Animal physiology; Djurfysiologi;

    Abstract : Popular Abstract in Swedish Dykresponsen Andningsuppehåll (apné) eller fridykning ställer stora krav på att så effektivt som möjligt disponera de förråd med syrgas som finns i kroppen. Känsliga organ såsom hjärnan och hjärtat kan inte klara sig utan syrgas någon längre tid. READ MORE

  3. 3. Severe hypoxemia during apnea in humans : Influence of cardiovascular responses

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Peter Lindholm; Karolinska Institutet.; Karolinska Institutet.; [2002]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diving response; breath holding; bradycardia; vasoconstriction; hypoxia;

    Abstract : When a diving human holds his or her breath, the heart beat slows and the blood vessels constrict in large portions of the body. In diving mammals such as seals, similar responses effectively conserve oxygen for the brain, enabling them to dive very deep and to stay underwater for a long time. READ MORE

  4. 4. Psychomotor and cardiorespiratory functions during inert gas sedation

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Anders Östlund; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arterial baroreflex; heart rate; gas density; hyperbaric bradycardia; inert gas; inspiratory loading; narcosis; nitrous oxide; sedation; ventilation;

    Abstract : Relative hypoventilation and bradycardia are commonly observed in both resting and exercising divers. Divers are exposed to a complex environment where there are increases of hydrostatic pressure, gas density and partial pressure of sedating inert gas. READ MORE

  5. 5. Human responses to cold and wind

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Désirée Gavhed; Karolinska Institutet.; Karolinska Institutet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bradycardia; blood pressure; clothing insulation; cold; exercise; heart rate; IREQ; mean skin temperature; metabolic rate; rectal temperature; subjective ratings; wind; Wind Chill Index; work.;

    Abstract : Cold is stressful for the human being and has physical, subjective and physiological effects. Body cooling must be prevented to provide for the worker's comfort and safety in cold workplaces. READ MORE
