2. 1. Physiological effects of apnoeic oxygenation using high-flow nasal oxygen

   Author : Ida-Maria Forsberg; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : In anaesthetic practice, the inability to oxygenate and ventilate patients is a much-feared complication with risk for severe hypoxia-induced adverse outcomes. By administrating oxygen in the absence of spontaneous ventilation, apnoeic oxygenation may overcome these challenges by a prolonged time with sufficient oxygenation. READ MORE

4. 2. Clinical and physiological consequences of preoxygenation using high-flow nasal oxygen in emergency anaesthesia

   Author : Albin Sjöblom; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Airway management;

   Abstract : Emergency anaesthesia is usually performed using a rapid sequence induction technique. The incidence of desaturation during rapid sequence induction is high, and preoxygenation prolongs the safe apnoea time. READ MORE

5. 3. Nasal airway nitric oxide : methodological aspects and influence of inflammation

   Author : Jörgen Palm; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Asthma; breath test; exhaled air; rhinitis; sinuses; sinusitis; diurnal variation; gender; nasal; oral; nitric oxide; volume flow rate; AIDS; HIV; endotoxin; gut; human; shock; allergy.;

   Abstract : Nitric oxide (NO) is an endogenously formed free radical gas involved in numerous biological processes. In 1991 NO was discovered to be present in exhaled air of humans. Soon after, it was reported that the largest amounts of NO were found in the upper airways, and that the levels of NO were increased in the lower airways of patients with asthma. READ MORE

6. 4. Studies on nitric oxide in the respiratory system

   Author : Ulla Schedin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : nitric oxide; endogenous; respiratory system; neonate; prematureinfant; animal; primate; elephant; chemiluminescence; electrochemical; nitrogen dioxide; trachea; nose; ;

   Abstract : Nitric oxide (NO) is formed in biological tissues and has regulatory functions in many organ systems. Endogenous NO has been found in exhaled air and NO is considered to have effects on the pulmonary circulation and bronchial tone, and to be one of the mediators for the circulatory adaptation at birth.

7. 5. A novel drug and device in anesthesia : with focus on breathing and upper airway physiology

   Author : Åse Lodenius; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Anesthesia-related airway complications are associated with hypoxia due to inability to secure or maintain the airway with subsequent insufficient ventilation and gas exchange. This thesis has explored the impact on airway integrity and respiratory regulation of two anesthetic compounds frequently used for sedation and a novel principle for oxygenation in patients at risk of hypoxia, in order to further improve patient safety during sedation and induction of anesthesia.
