  2. 6. Respiratory Sinus Arrhythmia and Emotion : Effects of pictorial stimuli and state anxiety

    Author : Peter Jönsson; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; state anxiety; emotion; HRV; heart rate variability; RSA; Respiratory sinus arrhythmia; Psykologi;

    Abstract : Respiratory sinus arrhythmia (RSA) refers to heart rate variations due to respiration, which results from parasympathetic nervous system activity mediated via the tenth cranial nerve, the vagus. Thus, the magnitude of RSA is considered as an index of cardiac vagal tone. This thesis explored RSA during emotional responding in healthy women and men. READ MORE

  4. 7. Humming, nitric oxide and paranasal sinus ventilation

    Author : Mauro Maniscalco; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The paranasal sinuses are air-filled bony cavities surrounding the nose. They communicate with the nose via the sinus ostia through which fluid and gases pass in both directions. A proper ventilation is crucial for sinus integrity and blockage of the ostia is a major risk factor for development of sinusitis. READ MORE

  7. 10. Ventilation of the Paranasal Sinuses. A study using the 133-Xenon Washout Technique

    Author : Bo Paulsson; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; auditive system and speech; single photon emission computed tomography; paranasal sinuses; ventilation; 133-xenon; chronic sinusitis; nose-sinus model; endoscopic sinus surgery; oxymetazoline; Otorhinolaryngology; Otorinolaryngologi; audiologi; hörsel- och talorganen; audiology;

    Abstract : A noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. READ MORE
