Critique of Quantitative Research Article Essay

look Critique, Part 2 Critique of Quantitative Research Article The existence who argon diagnosed with obstructive sleep apnea (OSA) often experience daytime drowsiness and are at risk for ischemic heart disease, arrhythmias, hypertension, and other vascular related problems (Hsu et al., 2007). There are several treatment options for people with OSA, which are weight loss, continuous positive airway pressure (CPAP), dental appliances, and operative procedure. This correction evaluates patients who have undergone uvulopalatopharyngoplasty (uvulopalatopharyngoplasty) to determine improvement and changes in functional parameters of their upper airway using quantitative videoendoscopic computer-assisted measurement (CAM) in hopes of exhibit improvement in the apnea-hypopnea index (AHI).Protection of Human ParticipantsThe authors describe this study as prospective in design. The study was conducted to evaluate the efficacy of UPPP, a surgical procedure for OSA, on patients who had sur gery six months prior (Hsu et al., 2007). It is presumed every(prenominal) patient gave consent for the surgical procedure. An assumption may be do that subjects were voluntary for the post surgical study because there was no give ear of further consents. It is not stated that this study had approval from an institutional retread board from the agency. The 19 male patients participated in overnight pre and operative non-invasive polysomnnographic studies (PSG).These tests take on the Epworth sleepiness scale recording, CAM of upper airway, and bio-data recording. PSG entails electroencephalogram (EEG), submental electromyogram (EMG), anterior tibialis muscle EMG, electrocardiogram (ECG), thoraco-abdominal motion, oronasal airflow (expired CO2), arterial oxygen saturation with pulse oximetry, and electrooculography (EOG). Images were enter for comparison evaluation surgically. The connote age of the subjects was 40.6 years with a mean body mass index (BMI) of 29.4, all who h ad UPPP after weakness the CPAP trial and other medical methods. info Collection and AnalysisThe major variables were labeled in association with the endoscopic photographs from the computer-assisted measurement (CAM) airway digest at the retropalatal level with calibrator in regards to showing airway dimensions in some(prenominal) pre and postoperative images (Hsu et al., 2007). There was no sign of manipulation of these variables other than from the postoperative images. The research team compiled the data to show the regression data of UPPP surgery were considerably correlated with postoperative improvement. This method of data array was used to analyze the correlation between modifications in surgical parameters and the postoperative position of OSA patients. The six-month postoperative, patients again underwent PSG, Epworth sleepiness scale recording, CAM of upper airway, and bio-data analysis.A nitty-gritty of eight videoendoscopic images were taken of all 19 subjects. P atients were analyzed during quiet airing and Muellers maneuver in both supine and erect positions at the retropalatal and retrolingual levels. The Muellers maneuver is a non-invasive procedure using fiber oculus endoscopic evaluation that measures both size, shape, and collapsibility of the upper airway (Friedman, 2009). Images were captured using a videocapture card, which was installed into the computer along with digital imaging software package. Transverse and longitudinal dimensions, as well as surface areas were measured using digital software to calculate the collapsibility of obstructive sites of the upper airway. Comparison was made between pre and postoperative images, which show significant improvement of the retropalatal area by 70% (Hsu et al., 2007).Data Management and AnalysisThe author indicates that the researcher who performed the upper airway measurements was not privy to patient information whether they were of preoperative or postoperative status (Hsu et al. , 2007). Following UPPP, the importance (p
