Data at the world health organization shows that around more than 100 million people worldwide suffer from Obstructive Sleep Apnea (OSA) and most sufferers go undetected. The purpose of this study is to develop an apnea monitor that can detect the symptoms of Obstructive Sleep Apnea using the Telemedicine Smartphone System (TmSS). The contribution of this study is the generation of telemedicine systems in sleep apnea monitoring devices. So that the monitoring tools can be effective and efficient when used, then the Obstructive Sleep Apnea monitoring tool is made with the TmSS system that can transmit data values wirelessly and in real-time. This tool uses a flex sensor to detect patient breathing. The output generated by the sensor is then conditioned on an analog signal conditioner (PSA) circuit. The signal output from the PSA is processed on the ATMega 328 microcontroller to get the respiration value which is then sent via Bluetooth HC-05 and displayed on an android smartphone device which will also display a warning notification in the event of stopping breathing (apnea). Based on the results of the measurement of respiration values compared with standard equipment produces the highest error value of 6.98% and the lowest of 0.00%. The tool can send data respiration values using the TmSS system properly. This tool can be implemented to detect the symptoms of Obstructive Sleep Apnea.

BCI technology as a widely used technique is gradually into daily life. Based on the study of this technique and taking advantage of MindSet extraction equipment of EEG which is available in the market, we design a portable sleep apnea monitoring tools which use MindSet as a platform, which has comfortable pillow structure. Monitoring equipment described in the text achieves real-time monitoring for apnea, also has an alarm function. Apnea syndrome on self-monitoring and alarm has better effects.

Obstructive Sleep

BACKGROUND Obstructive sleep apnea (OSA), the most common upper-airway disease, is closely associated with cardiovascular risk. However, the early detection of OSA is challenging, relying on polysomnography (PSG) or home sleep apnea test (HSAT) in hospitals. A novel technology, PPG (Photoplethysmography), has been developed for OSA screening. However, the validation of PPG-based smart devices is limited as compared to that for PSG or HSAT. OBJECTIVE This study aimed to investigate the feasibility and validity of PPG-based smart devices in the detection of OSA. METHODS A total of 119 consecutive outpatients were recruited from the Chinese PLA General Hospital and assessed using a smart watch, PSG or HSAT for a whole night sleep. RESULTS 17/119 patients were excluded due to poor quality of PPG-signals. Among the rest, 83 patients were diagnosed with OSA. Compared to HSAT devices, the accuracy, sensitivity, and specificity of PPG-based smart device in predicting moderate to severe OSA patients (Apnea Hypopnea Index, AHI≥15) were 87.9%, 89.7%, and 86.0%, respectively. Compared to PSG, the accuracy, sensitivity, and specificity in predicting the sleep apnea in patients (AHI≥5) were 81.1%, 76.5%, and 100%, respectively. Moreover, for moderate to severe OSA patients (AHI≥15), the predictive ability of PPG-based smart device in OSA did no differ significantly as compared to HSAT (P=0.75) or PSG (P=0.52). CONCLUSIONS The PPG-based smart devices demonstrated good performance in detecting OSA; nevertheless, validation in a large-scale population is imperative.

Buccal Flap

Purpose The 2 most commonly used operations to treat velopharyngeal inadequacy (VPI) are superiorly based pharyngeal flap and sphincter pharyngoplasty, both of which may result in hyponasal speech and airway obstruction. The purpose of this article is to (a) describe the bilateral buccal flap revision palatoplasty (BBFRP) as an alternative technique to manage VPI while minimizing these risks and (b) conduct a systematic review of the evidence of BBFRP on speech and other clinical outcomes. A report comparing the speech of a child with hypernasality before and after BBFRP is presented. Method A review of databases was conducted for studies of buccal flaps to treat VPI. Using the principles of a systematic review, the articles were read, and data were abstracted for study characteristics that were developed a priori. With respect to the case report, speech and instrumental data from a child with repaired cleft lip and palate and hypernasal speech were collected and analyzed before and after surgery. Results Eight articles were included in the analysis. The results were positive, and the evidence is in favor of BBFRP in improving velopharyngeal function, while minimizing the risk of hyponasal speech and obstructive sleep apnea. Before surgery, the child's speech was characterized by moderate hypernasality, and after surgery, it was judged to be within normal limits. Conclusion Based on clinical experience and results from the systematic review, there is sufficient evidence that the buccal flap is effective in improving resonance and minimizing obstructive sleep apnea. We recommend BBFRP as another approach in selected patients to manage VPI. Supplemental Material https://doi.org/10.23641/asha.9919352
