Obstructive Sleep Apnea Case Study

847 Words4 Pages

Obstructive sleep apnea (OSA) is characterized by partial or complete cessation of airflow and oxygen desaturation during sleep owing to upper airway collapse.1,2 The severity of sleep apnea depends on the abnormal size of the airway.3 In children, the major contributor to airway narrowing is hyperplasia of pharyngeal tonsils and adenoids.4 Moreover, pediatric craniofacial disharmony was strongly associated with sleep-disordered breathing (SDB). 5
Polysomnography is indicated when the clinical assessment suggests the diagnosis of childhood obstructive sleep apnea syndrome (OSAS), also in asthma if there is a clinical suspicion for an accompanying SDB disorder.6
Children with asthma had a significantly higher risk for SDB. Therefore, few authors …show more content…

The device was applied between 6:00 pm and 8:00 am and recorded data continuously throughout the night. During the test, all the children underwent recordings for ≥6 h in a quiet, appropriately prepared sleep room in the presence of one of their caretakers. 13 The TST has calculated accordingly to the childhood falling asleep and waking reported in a diary by the caretaker and compared to the changes of body position and HR recorded by the machine. The nocturnal awakenings were considered from the TST computation and removed from the final …show more content…

Obstructive respiratory events were scored as previously reported.14 In particular, the number of obstructive apneas (OA; n/h) plus hypopneas (H; n/h) was divided by the hours of TST and expressed as an obstructive apnea-hypopnea index (OAHI, n/h).15 Severe sleep respiratory condition was set at OAHI ≥ n. 10/h. We chose to evaluate central apnea index (CAI) calculating all central respiratory events recorded per hour of sleep (n/h TST), as previously reported. 16
Desaturation was considered in the presence of a drop ≥ 3% oxygen (O2). All O2 desaturations (n/h) from the baseline, mean SaO2 (%) and minimum SaO2 (%) were quantified. The oxygen desaturation index (ODI, n/h) was calculated as the total number of oxygen desaturations divided by the TST. Snoring (% of TST) was

Glenys Case Study Night Sweats

543 Words | 3 Pages

Thank you very much for referring Glenys along for further investigation of the abnormalities detected on the CT scan of her chest which was done for investigation of night sweats. As you have mentioned, she has seronegative rheumatoid arthritis for which she is normally on prednisolone, methotrexate and Arava, but the methotrexate and Arava have been stopped recently due to an elevated liver function test. The CT scan of her chest, abdomen and pelvis did not reveal any cause for her night sweats but did reveal the presence of mild, mid and upper lung paraseptal emphysema with some non-specific scarring in the basal segment of the right lower lobe basal lingula and anterior basal left lower lobe. There were multiple scattered small irregular cysts elsewhere throughout the lung. Alongside this, there were also two small pulmonary nodules in the right middle lobe and right lower lobe which were 3mm.

(Drouot et al., 2008). The more we began to explore sleep the more we came to realize the complexity of this seemingly simple project. We quickly realized that if we want to show improved sleep by decreased noise, we need a way to objectively measure sleep. If we want to show decreased incidence of delirium by improved sleep we need to consistently and accurately measure delirium and if we want to promote sleep we need create a silent

Thus, when a child shows distress they should be immediately removed from the study. In addition to this, the findings show that after the test, a lot of the children discontinued wetting the bed, taking a bottle and there were no negative changes in sleep pattern (Bain et al, 1958). Therefore this may have impacted the psychological field as the features of the experiment may have lead to these neutral or positive changes in

PSQI To Measure The Quality And Patterns Of Sleep In Adults

186 Words | 1 Pages

The PSQI is used to measure the quality and patterns of sleep in adults. It measures seven areas of sleep: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. For the purposes of the current study, the PSQI has been modified from a monthly questionnaire to a weekly questionnaire. This modified version will start with question 5A, (i.e., “During the past week, how often have you had trouble sleeping?”) and end with question 9 (i.e., “During the past week, how would you rate your sleep quality overall?”). It uses a Likert scale that ranges from “very bad” (3) to “very good” (0) sleep quality.

In the book it talks about how children are recommended to receive an average of 11 to 13 hours of sleep each night in order for them to avoid experiencing sleeping problems and the negative developmental outcomes. One of them includes short sleeping durations, this cause can easily be changed by simply modifying
