  2. 16. Respiratory inductive plethysmography (RIP) : calibration, breathing pattern analysis and external CO2 dead space measurement

    Author : Tomas Strömberg; Gert Nilsson; Per M. Gustafsson; Steffen Groth; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Respiratory inductive plethysmography (RIP) is an important tool for ventilatory monitoring in research studies because it has minimal influence on the spontaneous breathing pattern and because the rib cage and abdominal contributions to the breaths are measured. RIP measures changes in rib cage and abdominal cross-sectional areas which are translated into lung volume estimates via RIP calibration against e. READ MORE

  4. 17. The role of substance P in respiratory control in the newborn : effects of morphine and nicotine

    Author : Jonas Berner; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : We breathe in order to maintain oxygen, carbon dioxide and pH levels within the physiological range in response to the metabolic demands of the body. To achieve this, the respiratory control system is dependent on input from peripheral and/ central chemosensitive areas and on participation of different neuromodulator systems. READ MORE

  5. 18. Apnea and infection in neonates : mediatory role of interleukin-1Beta and prostaglandin E2

    Author : Annika Olsson Hofstetter; Karolinska Institutet; Karolinska Institutet; []
    Keywords : respiration; interleukin-1Beta; prostaglandin E2; newborns; rodents; brainstem;

    Abstract : The breathing pattern of infants, particularly preterm infants, is often irregular or periodic and is frequently interrupted by apnea. The latter represents a major concern in haematology, yet much remains unknown about its incidence, appearance, and pathophysiology. READ MORE

  6. 19. Perioperative management and molecular patterns in patients with obstructive sleep apnea

    Author : Eva Christensson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Obstructive sleep apnea (OSA) is a common disorder, both in the general and surgical population. While there is a steadily increased awareness of the disorder both in the society as a whole and within health care, unfortunately, most individuals with OSA still go undiagnosed. READ MORE

  7. 20. Pharmacological therapy in obstructive sleep apnea - Methodology and interventional aspects of carbonic anhydrase modulation

    Author : Erik Hoff; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; obstructive sleep apnea; carbonic anhydrase; endotype; drug therapy; hypoxia; hypoxia-inducible factor 1α; placebo;

    Abstract : BACKGROUND: Obstructive sleep apnea (OSA) is a highly prevalent disease with potential severe short- and long-term consequences such as daytime sleepiness and cardiovascular disease. Recurrent total or partial collapse of the upper airway during sleep leads to sleep fragmentation and intermittent hypoxia/hypercapnia. READ MORE
