Assessment of PPG & PAT to Detect Upper Airway Obstruction in Patients With Obstructive Sleep Apnea...

Sleep ApneaObstructive

The goal of this study is to collect raw waveform data for two separate noninvasive methods, both of which may be useful for the assessment of upper airway obstruction.

Obstructive Sleep Apnea, Retinal Vein Occlusion, Retinal Artery Occlusion

Retinal Vascular Occlusion

Obstructive sleep apnea is a common disorder linked to serious long-term adverse health consequences; such as hypertension, metabolic dysfunction, cardiovascular disease. Retinal vascular occlusion is related to many systemic illnesses especially hypertension. Obstructive sleep apnea is also related to vascular endothelial dysfunction and vascular endothelial growth factor elevation which causes vision threatening complications of retinal vascular occlusion. Therefore the relationship between obstructive sleep apnea and retinal vascular occlusion should be studied.

Pilot Study of the MultiSense Patch to Record Cardiopulmonary Data During Sleep and Wake Cycles...

Obstructive Sleep Apnea of Adult

The investigators are proposing to use a wearable device, MultiSenseTM, developed by Rhythm Diagnostic Systems, Inc. which has many sensors inside in a "Band-Aid" like strip in order to see if it can help diagnose capabilities in individuals suspected of having obstructive sleep apnea. The MultiSenseTM sensor is a self-contained, reusable, rechargeable, battery-powered, flexible strip, measuring 4 X 1.2 inches that simultaneously tracks and records a number of physiological health related parameters such as ECG, heart rate, pulse synchronized oxygen saturation, temperature, respiratory rate, depth of respiration and motion/position. One advantage of this device over current home diagnostic systems is the capability for recording over several nights. The objective is to compare multiple biometric parameters tracked by the MultiSenseTM to gold standard monitoring in an accredited sleep lab using polysomnography. Home monitoring will explore potential findings supportive of sleep apnea while monitoring at home during routine sleep over 5 to 7 nights. Enrolling 10 adults already scheduled for a medically indicated sleep study will help us to make these determinations. Subjects will wear the device, which is the size of a Band-Aid, via adhesive to their chest over a period of 10 days. Subjects will go about their normal daily activities and return the device via mail once completed.

Hypertension and Sleep Disordered Breathing in Pediatrics

HypertensionObstructive Sleep Apnea

The primary objective is to determine the prevalence of sleep disordered breathing in children with primary hypertension or pre hypertension. The secondary objectives are to determine any association factors for children with primary hypertension or prehypertension to have sleep disordered breathing be it gender, age, body mass index (BMI), family history (hx) or ethnic group.

Face of Sleepiness

Obstructive Sleep Apnea

The purpose of this pilot study is to find out whether successful treatment of obstructive sleep apnea makes people look less sleepy, for example by reducing swelling or dark circles under the eyes. In addition, this study will help determine whether facial photographs may be used to help identify patients who should be tested for sleep apnea and daytime sleepiness.

Obstructive Sleep Apnoea and Adipose Tissue Dysfunction

Obstructive Sleep ApnoeaObesity1 more

Dysfunctional adipose tissue predisposes to cardiovascular disease. Similarly, the risk of cardiovascular disease appears to be increased in subjects with obstructive sleep apnoea. Reduced adipose tissue oxygen availability has been described in obesity and may also be a mechanism in obstructive sleep apnoea. Hypoxia induces inflammation and fibrosis in adipose tissue which are factors contributing to cardiovascular risk. The investigators hypothesize that adipose tissue's oxygen uptake is reduced in subjects with obstructive sleep apnoea by comparing in vivo AT oxygenation and blood flow in tissue of control subjects.
