The most common type of sleep Apnea is obstructive sleep Apnea. However, another type does exist, and can be just as dangerous to the health. Whereas obstructive sleep Apnea, as the title suggests, relates to some sort of obstruction in the airways, including enlarged tonsils or adenoids, a deformed uvula or fatty tissue in the throat area, central sleep Apnea is caused by a dysfunction in the thalamus area of the brain and the mechanism that controls your breathing. ...

[The MRI study of upper airway on obstructive sleep Apnea hyponea syndrome] Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2008 Jul;22(13):593-6 Authors: Zha D, Qiao L, Ge Y, Deng Z, Xue T, Liu Y, Qiu J OBJECTIVE: To investigate the character of upper airway and to offer the reference for clinical treatment through observing the upper airway caliber and its corresponding pharyngeal wall of OSAHS patients by magnetic resonance imaging (MRI). METHOD: The upper airway of 33 obstructive sleep Apnea hyponea syndrome (OSAHS) patients diagnosed by PSG were analyzed and compared by MRI. The cross-sectional area of the upper airway and thickness of lateral parapharyngeal wall were calculated. The cross-sectional area of the upper airway and thickness of lateral and posterior pharyngeal wall were also measured in 20 nonsnoring age-matched normal subjects selected as the control group. RESULT: The cross-sectional areas of upper airway of OSAHS patients were smaller than that of the control. The Thickness of posterior pharyngeal wall and lateral pharyngeal wall of the retropalatal region, retroglossal region and epiglotttal region were thicker in patients group than that of the control. The thickness and length of the palate in patients group were larger than that of the control. The cross-sectional areas of retropalatal region of OSAHS patients had negative correlation with Apnea hyponea index (AHI). There was also negative correlation between t ...

Related Articles Morbidity due to obstructive sleep Apnea: insights from animal models. Curr Opin Pulm Med. 2008 Nov;14(6):530-6 Authors: Farré R, Montserrat JM, Navajas D PURPOSE OF REVIEW: Obstructive sleep Apnea (OSA) is a prevalent disorder with clinically well known mid-term and long-term consequences. It is difficult, however, to investigate the mechanisms causing morbidity in OSA from human studies, owing to confounding factors in patients. Animal research is useful to analyze the various injurious stimuli--intermittent hypoxia/hypercapnia, mechanical stress and sleep disruption--that potentially cause OSA morbidity. This review is focused on the most recent advances in our understanding of the consequences of OSA, achieved as a result of animal models. RECENT FINDINGS: Animal research has improved our knowledge of various aspects of the cardiovascular consequences of OSA: myocardial damage, left ventricular dysfunction, vasoconstriction, hypertension and atherosclerosis. The systemic and metabolic consequences of OSA--inflammation, insulin resistance, alterations in lipid metabolism and hepatic morbidity--have also been investigated with animal models. Our understanding of the mechanisms involved in the neurocognitive consequences of OSA--neuronal and brain alterations and cognitive dysfunctions--has also been improved through animal research. Moreover, animal models have recently been used to investigate the mechanisms of upp ...

[Diagnosis of obstructive level in pharynx with obstructive sleep Apnea hypopnea syndrome with multiple detector-row spiral CT] Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2008 Jul;22(13):600-2 Authors: Zhou M, Jiang M, Cheng Y, Li Z, Huang W, Xue F, Wang Q OBJECTIVE: To evaluate the diagnostic significance of multiple detector-row spiral CT(MSCT) in patients with obstructive sleep Apnea hypopnea syndrome (OSAHS). METHOD: Sixty-seven patients with OSAHS and 40 volunteers were scanned. The CT imagings from the nasaopharyngeal floor to the glottis obtained. The relevant dimensions of area, diameter, thickness of retropharyngeal tissue were measured in some regions in imagings including nasaopharynx, oralopharynx and hypopharynx, as well as the narrowest region in pharynx. RESULT: 1) The values of area, left-right diameter and front-back diameter of oralopharyngeal imagings of patients with OSAHS were narrowest regions which were (133.5 +/- 32. 9) mm2, (12.5 +/- 2.0) mm, (10.4 +/- 1.8) mm respectively. The value of above parameters of oralopharyngeal imagings of volunteers were (238.5 +/- 46.5) mm2, (20.4 +/- 3.1) mm, (21.1 +/- 4.0) mm respectively. The values of two groups had marked difference by statistics (P< 0.01). 2) The narrowest regions were located in oraopharynx in the imagings of 58 patients with OSAHS, which located in soft palate site in 19 patients, in oralopharynx site in 11 patients and in retro-lingua site in 28 patie ...

Blood flow and metabolic regulation in seal muscle during Apnea. J Exp Biol. 2008 Oct;211(Pt 20):3323-32 Authors: Ponganis PJ, Kreutzer U, Stockard TK, Lin PC, Sailasuta N, Tran TK, Hurd R, Jue T In order to examine myoglobin (Mb) function and metabolic responses of seal muscle during progressive ischemia and hypoxemia, Mb saturation and high-energy phosphate levels were monitored with NMR spectroscopy during sleep Apnea in elephant seals (Mirounga angustirostris). Muscle blood flow (MBF) was measured with laser-Doppler flowmetry (LDF). During six, spontaneous, 8-12 min apneas of an unrestrained juvenile seal, apneic MBF decreased to 46+/-10% of the mean eupneic MBF. By the end of Apnea, MBF reached 31+/-8% of the eupneic value. The t(1/2) for 90% decline in apneic MBF was 1.9+/-1.2 min. The initial post-apneic peak in MBF occurred within 0.20+/-0.04 min after the start of eupnea. NMR measurements revealed that Mb desaturated rapidly from its eupenic resting level to a lower steady state value within 4 min after the onset of Apnea at rates between 1.7+/-1.0 and 3.8+/-1.5% min(-1), which corresponded to a muscle O(2) depletion rate of 1-2.3 ml O(2) kg(-1) min(-1). High-energy phosphate levels did not change with Apnea. During the transition from Apnea to eupnea, Mb resaturated to 95% of its resting level within the first minute. Despite the high Mb concentration in seal muscle, experiments detected Mb diffusing with a translational diff ...

[Effects of short-term continuous positive airway pressure treatment on arterial stiffness in patients with obstructive sleep Apnea hypopnea syndrome] Zhonghua Yi Xue Za Zhi. 2008 Apr 29;88(17):1189-91 Authors: Lü YH, He ZM, Dong XS, Li J, Han X, An P, Wang L, He QY, Han F OBJECTIVE: To investigate the effect of short-term continuous positive airway pressure (CPAP) treatment on the arterial stiffness in patients with obstructive sleep Apnea hypopnea syndrome (OSAHS). METHODS: Cardio ankle vascular index (CAVI) and blood pressure (BP) were measured before and after sleep in 60 non-hypertensive patients with OSAHS and gender and 60 age-matched healthy controls. CPAP was administrated in 22 of the 60 OSAHS patients. And on the first and third days of the CPAP treatment CAVI and BP were measured in the morning, i. e., after sleep. RESULTS: In the morning, the CAVI of the OSAHS patients was 8.0 +/- 1.2 m/s, significantly higher than that before sleep (7.3 +/- 1.0, P = 0.000), the diastolic BP (DBP) was (86 +/- 12) mm Hg, significantly higher than that before sleep (83 +/- 13 mmHg, P = 0.001), and the mean BP (MBP) was (101 +/- 12) mm Hg, significantly higher than that before sleep (98 +/- 14, P = 0.00116). However, there were no significant differences in these parameters among the controls The systolic BP (SBP) of the OSAHS patients did not changed significantly after sleep, however, there was a tendency to decrease in the controls [(123 ...

[Voice quality evaluation in patients with obstructive sleep Apnea syndrome treated with uvulopalatopharyngoplasty (UPPP)] Pol Merkur Lekarski. 2008 Jul;25(145):46-50 Authors: Kosztyła-Hojna B, Rogowski M, Olszewska E, Kasperuk J MATERIAL AND METHODS: The evaluation of voice quality of 22 patients with obstructive sleep Apnea syndrome (OSAS), who underwent uvulopalatopharyngoplasty (UPPP), was performed. The voice quality was assessed before the operation, and 1 month and 6-months after the procedure. The grade of dysphonia was determined on a six-grade dysphonia scale according to the Union of European Phoniatricians. Maximum phonation time (MPT) was analyzed. The acoustic examination of voice was performed determining fundamental frequency (F0) value and shimmer, jitter and NHR acoustic parameters. Formants analysis of voice was made estimating the level of F1, F2, F3 and F4 formants. RESULTS: Registered hearing dysphonia directly after the surgery was transient. The surgery did not significantly change F0 and jitter parameters that decrease the grade intensification of dysphonia. The reduction of maximum phonation time, changes in jitter and NHR acoustic parameters as well as the reduction of F3 and F4 formants confirmed the occurrence of open nasality directly after UPPP. CONCLUSION: Registered voice quality and timbre disturbance after UPPP were periodic. PMID: 18839614 [PubMed - in process] ...

[The effect of short-time continuous positive airway pressure treatment on insulin sensitivity in patients with obstructive sleep Apnea-hypopnea syndrome and type 2 diabetes] Lin Chung Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2008 Jul;22(13):597-9 Authors: Wang H, Wang L, Liu J OBJECTIVE: To investigate the effects of short-time continuous positive airway pressure treatment before the surgery on insulin sensitivity in patients with obstructive sleep Apnea-hypopnea syndrome and type 2 diabetes who need the operation of uvulopalatophargngoplasty. METHOD: Thirty cases of patients with moderate and severe obstructive sleep Apnea-hypopnea syndrome and type 2 diabetes who need the operation of UPPP were included in this study. The Apnea hypopnea index (AHI) and LSaO2 and the insulin sensitivity index (ISI) was evaluated by homeostasis model assessment (HOMA), after 7 days of effective CPAP treatment. Subsequently, the data of the PSG and the ISI were rechecked and compared to the data previously achieved. RESULT: After 7 days of effective CPAP treatment, the level of AHI and LSaO2 changed (P < 0.05). The level of ISI improved (P < 0.05), while the level of AHI was correlated with fasting blood insulin level (r = 0.6365, P < 0.05) and was inverse correlated with insulin sensitivity (r = - 0.6229, P < 0.05). There was an negative correlation between LSaO2 and fasting blood insulin level (r = -0.8889, P < 0.05), and there was a correlation between ...
