{"title":"[A simple procedure for quantitative and time coded detection of snoring sounds in apnea and snoring patients].","authors":"J Schäfer","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>A simple technique for time-encoded recording of snoring sounds is presented. An electronic circuit connected to a stereo cassette recorder via cord remote control will start the recorder when the sound pressure of the snoring sound surpasses a preset level. The snoring sound is recorded on one track of the cassette recorder. The other track is used for the time code. Every 120 seconds the tape recorder is switched on by the electronic circuit and a short high level signal is recorded. The time interval between two time coding signals equals the snoring time. Analysis of the time coding signals is performed by an A/D converter installed in a Personal Computer. The converter amd accompanying software are used to calculate the duration of the intervals between the coding signals. The results are displayed graphically where sleeping time is plotted against snoring time (Fig.2). The length of each bar equals the snoring time in seconds for each 120 second interval. Snoring periods can be recognised at a glance and the snoring pattern can be evaluated. Three cases studies are presented demonstrating the performance of the technique. A 39-year-old female with nonpathological snoring (Fig.2), a 45-year-old male with heavy and regular snoring (Fig. 3) and a 36-year-old male with a full-blown Pickwickian Syndrome (Fig. 4).

The ciliated cells were acquired by the tissue cultivation of small pieces of nasal mucosa obtained during surgical interventions in the paranasal sinuses. The experiments were performed in a chamber where the cells were superfused by a tyrode solution. The ciliary beat was measured by a microscope photometer built into an inverted microscope. During the measurements the diaphragm aperture of the photometer was positioned over the cilia in such a manner that the changes of light intensity resulting from the movement of the cilia could be registered. The frequency of the ciliary beat was estimated by counting the individual beats. The ciliary beat during control conditions was studied as well as the influence of temperature. Cooling of the experimental chamber resulted in a significant reduction of the frequency of the ciliary beat.

Since the original description, these peculiar vascular structures have been detected in almost every organ and tissue. In respect of the head and neck area, arteriovenous anastomoses have been mainly observed in the nasal mucosa of either humans or different animals and in the rabbit ear; the latter offers a unique chance for in-vivo studies using the ear chamber technique. Nevertheless, the existence of arteriovenous anastomoses in the nasal mucosa has often been denied. In the present study, we examined the endonasal vascular system of the rabbit by means of light- and transmission electron microscopy. No evidence for the existence of arteriovenous anastomoses could be found in the respiratory part of the nasal mucosa whereas in the deeper layers of the olfactory mucosa several vascular structures could be encountered that were similar to the glomerula digitalia of fingertips. It is emphasised that these vessels must be regarded as true arteriovenous anatomoses which might play a potential role in endonasal thermoregulation.</p>","PeriodicalId":76098,"journal":{"name":"Laryngologie, Rhinologie, Otologie","volume":"67 8","pages":"395-9"},"PeriodicalIF":0.0,"publicationDate":"1988-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14340136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
