1. The human diving response : effects of temperature and training
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. Cardiovascular and respiratory effects of apnea in humans
Abstract : This thesis deals with cardiovascular and respiratory effects of apneas in humans. During apnea (breath-holding), a number of interacting cardiovascular reflexes are initiated, and together these reflexes are called the “diving response”. READ MORE

3. Severe hypoxemia during apnea in humans : influence of cardiovascular responses
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. Psychomotor and cardiorespiratory functions during inert gas sedation
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. Human responses to cold and wind
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
