ABSTRACT

OBJECTIVE To explore the effect of the pip fixation of the chest on air leakage through continuous positive airway pressure (CPAP) treatment. METHODS 106 patients with obstructive sleep apnea hypopnea syndrome were enrolled for this study. All patients underwent a whole night automatic titration for CPAP treatment. The patients included were divided into two groups randomly. For one group, the pipes were fixed on the chest (fixed group), while for the other group, there were no additional fixations for the pipes (control group). The data of all patients, including age, body mass index, AHI, and results of the titrations, were all collected for analyses. RESULTS Among the patients included, 42 patients belonged to the fixed group (39. 6%), while 64 patients belonged to control group (60. 4%). The average oxygen saturation of the Pipe-fixed group was significantly higher than that of the control group, while there were no significant differences for other parameters between the groups. However, the air leakage volume of the fixed group, (26. 5±7. 3)L/min,was significantly lower than that of the control group, (29. 9±9. 1)L/min (P=0. 041). The linear regression analyses suggested that the average pressure(coefficient=2. 124,P<0. 001) and the fixation of the pipe (coefficient=-2. 541, P=0. 050) had predictive value for the air leakage volume (P<0. 05). The equation was: the air leakage volume=13. 093+2. 124xthe average pressure -2. 541 × the fixation of the pipe (the data is 2 for the fixed group and 1 for the control group), the R square and the adjusted R square values of the analyses were 0. 398 and 0. 386. CONCLUSION The treatment pressure is positively related to the air leakage volume in CPAP treatment, a higher pressure suggested a higher potential air leakage volume, while the fixation of the pipe could be helpful in reducing the air leakage volume.

ABSTRACT

OBJECTIVE We hypothesized that unstable ventilatory control(high loop gain, LG) could predict the short-term efficacy of positive airway pressure therapy in patients with obstructive sleep apnea(OSA). METHODS 42 adult patients with OSA, M/F=39/3, were studied. The stability of the ventilatory control system(LG) was quantified by fitting a simplified mathematical model to the spontaneous ventilatory pattern obtained via polysomnography. LG, pulmonary function test results, and other PSG parameters were analyzed in patients who had post-treatment AHI≥10 events/hr(non-responders) using auto-positive airway pressure therapy. RESULTS The subjects aged(40±8) years, apnea-hypopnea index(AHI) were 68.2[42.9,81.0]events/hr). Nine patients(34.6%) were non-responders. Twenty pat ients(47.6%) had residual AHI<5 events/hr. Loop gain and pre-treatment mixed apnea index were higher in the non-responders versus responders(0.74 [0.62, 0.82] vs 0.49[0.37, 0.77], P =0.035) and(11.0[4.3, 22.9] vs 2.0[0.2, 5.3], P =0.004). In the 26 patients with LG>0.6, nine(34.9%) had posttreatment 5 events/hr≤AHI<10 events/hr. And all of the non-responders had LG(n=9, 34.9%). The difference was signif icant between the LG>0.6 a nd LG<0.6 group(P =0.007). CONCLUSION Loop gain and mixed apnea index was higher in patients with residual AHI>10 events/hr after short-term auto-PAP therapy. Ventilatory control stability evaluation might have predictive value for PAP treatment efficacy in OSA patients.

ABSTRACT

Objective@#To investigate the sleep-related deglutition in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) and its correlation with sleep stage and cortical arousals. @*Methods@#From December 2015 to September 2017, simultaneous polysomnography and pharyngeal pressure monitoring were performed in 23 adult patients with OSAHS, Mann-Whitney U test were employed to analyze the following parameters: (1) the relationship between arousal and deglutition; (2) the effect of sleep stage on deglutition; (3) The relationship between the frequency of deglutition and the severity of OSAHS. @*Results@#The subjects in this study aged (43±12) years, and the mean apnea-hypopnea index (AHI) was (49.2±27.7) times/hour. A total of 1 382 deglutition were recorded during sleep, with a median of 9.2[5.8, 13.8]times/person. There was a positive correlation between deglutition frequency and AHI(r=0.570, P=0.005) and negatively correlated with oxygen saturation (r=-0.639, P=0.001). The majority of the deglutition (73.7%) occurred after the respiratory event and in association with respiratory arousal. Deglutition occurred more in Non-rapid eye movement sleep stage 1 (N1) than N2, N3 and REM sleep (Z=-3.680, P<0.001; Z=-2.746, P=0.006; Z=- 3.490, P<0.001). @*Conclusions@#The occurrence of deglutition in patients with OSAHS is associated with cortical arousals. Deglutition frequency increased with the severity of apnea and affected by sleep staging.

ABSTRACT

<p><b>BACKGROUND</b>Obstructive sleep apnea syndrome (OSAS) has been shown to generate hypertension and endothelial dysfunction. Retinal vessel is the only vessel that can be observed directly and noninvasively; retinal vascular abnormalities can serve as a predictive marker for the occurrence, clinical course, and prognosis of cardiovascular and cerebrovascular diseases. The objective of this study was to identify the effect of OSAS severity on the morphological changes of retinal vessels.</p><p><b>METHODS</b>Adult patients complained of snoring were included in this study. The patients' general information, polysomnography, and fundus photography parameters including central retinal artery equivalent (CRAE), central retinal vein equivalent (CRVE), and arteriole-to-venule ratio (AVR) were collected. Patients were divided into four groups according to their apnea-hypopnea index (AHI) results: Group I, AHI ≤5/h; Group II, 5/h < AHI ≤30/h; Group III, 30/h < AHI ≤60/h; and Group IV, AHI> 60/h.</p><p><b>RESULTS</b>A total of 133 patients were included in this study with 111 males (83.5%) and 22 females (16.5%). Mean age was 41.6 ± 9.9 years, and the mean body mass index was 28.1 ± 4.0 kg/m2. AHI ranged between 0 and 130.8/h with a mean of 39.1 ± 30.7/h. There were 24, 34, 35, and 40 patients in Group I, Group II, Group III, and Group IV, respectively. Significant differences were found for AHI (F = 388.368, P< 0.001), minimal pulse oxygen saturation (F = 91.902, P< 0.001), and arousal index (F = 31.014, P< 0.001) among four groups; no significant differences were found for CRAE (F = 0.460, P = 0.599) and CRVE (F = 0.404, P = 0.586) among groups; there were significant differences for AVR between Group I and Group IV (63.6 ± 5.1% vs. 67.2 ± 5.5%, P = 0.010) Group II and Group IV (64.5 ± 6.0% vs. 67.2 ± 5.5%, P = 0.030), and Group III and Group IV (64.7 ± 4.1% vs. 67.2 ± 5.5%, P = 0.043). A main group-by-AHI effect was found on the AVR: patients with higher AHI showed higher AVR results (r = 0.225, P = 0.009). Multivariate logistic regression analysis was used for multi-variable factors. A group-by-age effect was found on the AVR: younger patients showed higher AVR results (β = -0.001, P = 0.020).</p><p><b>CONCLUSIONS</b>This study indicated that increased AVR of retinal vessel can be observed in extremely severe OSAS patients. For patients with OSAS, retinal vascular abnormalities may become an early indication for further cardiovascular abnormalities.</p>

ABSTRACT

OBJECTIVE To evaluate the value of Epworth sleepiness scale(ESS) combined with home-based portable monitoring(PM) in the diagnosis of patients with obstructive sleep apnea syndrome(OSAS). METHODS Adult OSAS patients who visited Beijing Tongren Hospital and complained of snoring were included in this study. The overnight polysomnography(PSG) and the ESS were completed at the sleep center and the portable multi-channel monitoring was completed within one week. Subjects were divided into two groups according to their apnea hypopnea index(AHI) of PSG: simple snoring or mild OSAS group(AHI<15/h) and moderate-severe group(AHI≥15/h). The ESS score, respiratory disturbance index(RDI) of PM and other parameters were compared and the correlation of AHI with ESS scores, RDI were analyzed. The sensitivity and specificity of ESS score≥9 points, RDI≥15/h in the diagnosis of moderate-severe OSAS were calculated. RESULTS A total of 51 subjects were included in this study with 42 males(82.4%) and 9 females(17.6%). Mean age was(43.8±10.8) years, and the mean body mass index was(27.9±4.5)kg/m2; ESS scored 1-24 points and mean(8.6±5.0) points, 18 cases with ESS score ≥9 points; AHI ranged between 2.5 and 99.8/h with a mean of(37.4±29.8)/h. There were 19(37.3%) and 32(62.7%) patients in snoring-mild group and moderate-severe group, respectively. There was significant difference for ESS scores between the two groups(9.9±5.1 vs 6.6±4.2 points, P<0.05),RDI in moderate-severe OSAS group was significantly higher than that in snoring-mild group[(49.4±23.1)/h vs (6.8±4.5)/h, P<0.001)]. There was a positive correlation between the ESS score and PSG derived AHI(r =0.435, P =0.002); the PM derived RDI were significantly correlated with PSG derived AHI in snoring-mild group(r =0.706, P=0.001), moderate-severe group(r =0.873, P=0.000) and patients with ESS score ≥9 points(r =0.967, P=0.000). At a PSG threshold AHI=15/h, the sensitivity and specificity for ESS score ≥9 points were 45.2% and 78.9%; the PM derived RDI≥15/h had a sensitivity and specificity of 84.4% and 84.2%, respectively; the sensitivity and specificity for each individual screening tool along with the combination of ESS and PM were 100.0% and 100.0%. CONCLUSION ESS combined with PM diagnostic method is a valuable measure for the diagnosis of moderate and severe OSAS patients.

ABSTRACT

<p><b>BACKGROUND</b>Obstructive sleep apnea/hypopnea syndrome (OSAHS) and laryngopharyngeal reflux (LPR) disease have a high comorbidity rate, but the potential causal relation between the two diseases remains unclear. Our objectives were to investigate the esophageal functional changes in OSAHS patients and determine whether OSAHS affects LPR by affecting esophageal functions.</p><p><b>METHODS</b>Thirty-six OSAHS patients and 10 healthy controls underwent 24-h double-probed combined esophageal multichannel intraluminal impedance and pH monitoring simultaneously with polysomnography. High-resolution impedance manometry was applied to obtain a detailed evaluation of pharyngeal and esophageal motility.</p><p><b>RESULTS</b>There were 13 OSAHS patients (36.1%) without LPR (OSAHS group) and 23 (63.9%) with both OSAHS and LPR (OSAHS and LPR group). Significant differences were found in the onset velocity of liquid swallows (OVL, P = 0.029) and the percent relaxation of the lower esophageal sphincter (LES) during viscous swallows (P = 0.049) between the OSAHS and control groups. The percent relaxation of LES during viscous swallows was found to be negatively correlated with upright distal acid percent time (P = 0.016, R = -0.507), and OVL was found to be negatively correlated with recumbent distal acid percent time (P = 0.006, R = -0.557) in the OSAHS and LPR group.</p><p><b>CONCLUSIONS</b>OSAHS patients experience esophageal functional changes, and linear correlations were found between the changed esophageal functional parameters and reflux indicators, which might be the reason that LPR showed a high comorbidity with OSAHS and why the severity of the two diseases is correlated.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore whether there were differences between the results of automatic titration and the results of manual titration for positive airway pressure treatment in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its influencing factors, the results might provide a theoretical basis for the rational use of two pressure titration methods.</p><p><b>METHODS</b>Sixty one patients with OSAHS were included in this study. All patients underwent a manual titration and an automatic titration within one week. The clinical informations, polysomnography data, and the results of both two titration of all patients were obtained for analysis.</p><p><b>RESULTS</b>The overall apnea/hypopnea index was (63.1 ± 17.7)/h, with a range of 14.9/h to 110.4/h. The treatment pressure of manual titration was (8.4 ± 2.1) cmH(2)O, which was significantly lower than the treatment pressure of automatic titration, (11.5 ± 2.7) cmH(2)O (t = -9.797, P < 0.001). After using a ΔP of 3 cmH(2)O for the cutoff value (ΔP was defined as the difference of automatic titration and manual titration), it was found that the pressure of automatic titration was significantly higher in patients with a ΔP > 3 cmH(2)O than in patients with a ΔP ≤ 3 cmH(2)O, which was (13.3 ± 2.3) cmH(2)O vs (10.0 ± 2.0) cmH(2)O (t = -6.159, P < 0.001). However, there were no differences for the pressure of manual titration between these two groups, which was (8.6 ± 2.4) cmH(2)O vs (8.3 ± 2.0)cmH(2)O (P > 0.05). There was no significant difference in age, body mass index, neck circumference, abdomen circumference, apnea hypopnea index, and arterial oxygen saturation between these two groups.</p><p><b>CONCLUSIONS</b>The treatment pressure of automatic titration is usually higher than that of manual titration. For patients with a high treatment pressure which is derived from automatic titration, a suggestion about manual titration could be given to decrease the potential treatment pressure of continuous positive airway pressure, which may be helpful in improving the comfortableness and the compliance of this treatment.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the correlation between upper airway CT measurement value and severity of patients with obstructive sleep apnea hypopnea syndrome (OSAHS).</p><p><b>METHODS</b>The upper airway of 82 patients with OSAHS were scanned by CT during normal respiration. The 3-D CT measurement were made in lateral and anterior-posterior diameters, cross-section areas and volumes of retropalatal and retroglossal region.</p><p><b>RESULTS</b>The lateral diameters and cross-section areas of every research plane were negatively correlated with apnea and hypopnea index (AHI), in particular the minimal lateral diameter of the whole airway (r = -0.558, P < 0.01). For volumes, AHI decreased with larger volume of nasal cavity, nasopharyngeal cavity and velopharyngeal cavity (P < 0.05 or P < 0.01). The negative correlation between AHI and proportion of cavity volume to the bone frame of velopharyngeal area and whole upper airway were significant (P < 0.05 or P < 0.01). But the correlation between AHI and volume of velopharyngeal soft tissue, the proportion of soft tissue to the bone frame volume of velopharyngeal area, the proportion of soft tissue to the bone frame volume of whole upper airway was significant positive, as well as the correlation between AHI and the proportion of soft tissue to the cavity volume of velopharyngeal area and whole upper airway (P < 0.05 or P < 0.01).</p><p><b>CONCLUSIONS</b>To evaluate the severity of OSAHS with upper airway CT measurement, there is no difference between 3-D parameters and 2-D parameters. In terms of the whole airway, the lateral diameters, the cross-section area, the cavity volume, the soft tissue of the upper airway, are meaningful to evaluate the severity of disease, in particular the measurement of velopharyngeal area.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To assess the accuracy of pulse transit time (PTT) in classification of apnea events, and collect data for clinical application reference.</p><p><b>METHODS</b>Thirty-two obstructive sleep apnea-hypopnea syndrome (OSAHS) patients included in the research had Polysomnography (PSG), and 10 305 apnea events were recorded. All the events were analyzed by PTT and esophageal pressure (Pes) respectively. The results were analyzed to assess the accuracy of PTT and compare the accuracy of pulse transit time between REM stage and NREM stage, and analyze the correlation between age, body mass index (BMI), apnea hypopnea index (AHI) and concordance rate in every patient.</p><p><b>RESULTS</b>The total concordance rate between PTT and Pes in classification of apnea was 96.7% (9970/10305). The sensitivities of PTT in detecting central, mixed and obstructive apnea were 88.0%, 91.3% and 97.8% respectively and the specificities were 99.8%, 97.8% and 92.8% respectively. The false determinations of apnea events mainly concentrated on the false determinations between the obstructive and mixed apnea. There was no statistical significant between the accuracy of PTT in different sleep stages. There was a negative relationship between the age, BMI, Lowest SaO2, AHI and the concordance rate.</p><p><b>CONCLUSIONS</b>There was good concordance between PTT and Pes in classification of apnea. PTT had very high sensitivity and specificity in detecting all kinds of apnea. This study showed that PTT can detect respiratory drive noninvasively with high accuracy.</p>

ABSTRACT

<p><b>OBJECTIVE</b>The distribution of upper airway obstruction sites can be identified quantitatively and dynamically with continuous airway pressure measurements in obstructive sleep apnea hypopnea syndrome ( OSAHS) patients. Its value as a clinical predictor for the outcome of revised uvulopalatopharyngoplasty was evaluated.</p><p><b>METHODS</b>The upper airway obstruction sites (transpalatal level, tongue base or hypolarynx level) were determined preoperatively with overnight upper airway pressure monitoring and concurrent polysomnography (PSG). Of one's total amount of obstructive events, the proportion of apnea/hypopnea events located at Transpalatal level was quantified as contribution of transpalatal obstruction. Of all OSAHS patients, 26 males and 1 female underwent revised uvulopalatopharyngoplasty (2 had same stage transpalatal advancement pharyngoplasty) and had follow-up PSG 6. 33 +/- 0.84 months after surgery. The relationship of transpalatal obstruction proportion, age, tonsil size and body mass index (BMI) and the reduction in apnoea hypopnea index (AHI) was analyzed.</p><p><b>RESULTS</b>The AHI (times/hr) of 27 subjects decreased from 63.9 +/- 20.7 to 28.4 +/- 25.4. The response rate was 51.9% (defined as AHI reduction over 50%). Correlation between the transpalatal obstruction proportion and the AHI reduction percentage was significant (r = 0.609), so was the degree of the tonsil size (r = 0.511). The proportion of tongue base level obstruction showed a negative correlation for the AHI reduction. Patients with oropharynx obstruction percentage > or = 70% had a success rate of 90% and all patients with oropharynx obstruction percentage <60% responded poorly to the operation. The regression model showed distribution of obstructive sites, along with tonsil size and other PSG parameters could predict 66.7% of the postoperative AHI of transpalatal level surgery (F = 6.701, P = 0.001) .</p><p><b>CONCLUSIONS</b>Contribution of transpalatal level obstruction has significant predictive value to the outcome of transpalatal level surgery in OSAHS patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To understand how sleep stage and position influence the mechanisms for pharyngeal collapse in different levels of upper airway (UA), overnight state-related changes and postural variation in obstructive sites in obstructive sleep apnea hypopnea syndrome (OSAHS) patients were studied.</p><p><b>METHODS</b>Fifty four OSAHS patients underwent overnight upper airway pressure monitoring during polysomnography. The lower limits of the UA obstruction were determined and their relationship with sleep stage, position, age, body mass index and apnea hypopnea index (AHI) were investigated.</p><p><b>RESULTS</b>All 54 patients had oropharynx (14 837 of the 23 172 analyzed events) and tongue base obstruction (5605/23,172), 2532 events were located at the oropharynx with extension to tongue base. Twenty nine patients has hypopharynx obstruction (105/23 172). Of the total amount of apnea hypopnea, the portions of obstruction located at tongue base level increased (t = 8.790, P = 0.000) in rapid eye movement (REM) sleep while those located at oropharynx decreased (t = -6.846, P = 0.000). Indexes of the apnea hypopnea caused by tongue base obstruction raised (t = 6.189, P = 0.000). Although the overall AHI in supine position was higher than in lateral position (t = 4.000, P = 0.000), increases in indexes of both the apnea hypopnea caused by tongue base (supine, 17.1 +/- 13.8 vs. lateral, 13.9 +/- 14.6) and oropharynx obstruction (44.3 +/- 20.3 vs. 37.2 +/- 25.9) were without significance (P > 0.05). Distribution of obstructive site varied little with different position (P > 0.05).</p><p><b>CONCLUSIONS</b>Upper airway obstruction involves more than one specific site of the upper airway and the oropharynx is the most common collapse site. Obstructive sites are likely to extend to lower levels during REM sleep. Sleep position has little effect on the distribution of obstructive site.</p>

ABSTRACT

OBJECTIVE To investigate the effects of obstructive sleep apnea hypopnea syndrome on the quality of life of the patients. METHODS The quality of life was assessed with the Medical Outcomes Study SF-36 Health Survey in 145 patients with OSAHS and 17 snorers without OSAHS. Excessive Daytime Sleepiness was assessed with Epworth Sleepiness Scale. Pearson linear correlation and stepwise multiple regression analysis were used to study the association between each domain score of SF-36 and patients information,PSG parameters,EDS scores. RESULTS Three domains of SF-36 correlated negatively with Body Mass Index. Four domains correlated negatively with EDS. Three domains and total score correlated significantly with the lowest oxygen saturation. Two domains correlated negatively with the longest time of apnea. AHI and the lowest oxygen saturation have a mild side effect on the quality of life. BMI and EDS score have significantly side effect on the quality of the life. CONCLUSION Comparing to the mild OSAHS patients and snorers without OSAHS,the severe OSAHS patients have worse quality of life. EDS score and BMI have a significantly side effect on the severe OSAHS patients. OSAHS has a side effect on the quality of life of the patients.
