1. Cardiovascular and respiratory effects of apnea in humans
Sammanfattning : 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”. LÄS MER
2. On the Formation and Physical Behaviour of Exhaled Particles
Sammanfattning : Aerosol particles are generated in human airways and leave the body with exhaled air. The particles originate from the respiratory tract and contain non-volatile compoundsthat potentially may be used as biomarkers for various medical conditions. To utilise any information provided by the particles, they must be characterised. LÄS MER
3. The human diving response : effects of temperature and training
Sammanfattning : 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. LÄS MER
4. Aspects on patient experiences and participation in magnetic resonance imaging including breath-hold acquisitions
Sammanfattning : .... LÄS MER
5. Hypoxic Blackout in Serial Freediving – Protective Mechanisms and Risk Factors
Sammanfattning : Breath-hold diving or freediving exposes the body to stressors such as low oxygen and high carbon dioxide levels in the blood, increased hydrostatic pressure, and cold. The reduction in blood oxygen levels is considered a primary factor for loss of consciousness while diving. This is known as hypoxic blackout. LÄS MER
