This document summarizes the work of the CPAP and bilevel PAP therapy for OSA Technical Expert Panel working group. For positive airway pressure (PAP) therapy, the most pressing current coverage barriers identified were: an insufficient symptom list describing all potential symptoms in patients with mild OSA; the 4 h per night of PAP usage requirement to keep the device; the additional sleep studies requirement to re-qualify for PAP or supplemental oxygen; and the inability to use telehealth visits for follow-up visits. Critical evidence supports changes to current policies and includes: symptom list inadequate to cover all scenarios based on updated clinical practice guidelines; published evidence that 2 h per night of PAP use can result in benefit to quality of life and other metrics; the costs of another sleep study not justified for all nonadherent patients or for supplemental oxygen due to other types of assessment currently available; and the remarkable success and acceptance of telehealth visits.

Study Objectives: Clinical benefit from positive pressure therapy is dependent on treatment adherence. Extreme weather events, such as floods, hurricanes, and tornadoes, can contribute to nonadherence by electricity loss and mandatory evacuation. We aimed to evaluate the concerns and behaviors of regular positive airway pressure users surrounding the extreme weather event Hurricane Irma.

Epidemiology has identified an association between the use of pacifiers and protection from sudden infant death syndrome (SIDS). The use of pacifiers for SIDS prevention fails to gain adoption partly because there is no widely accepted physiologic mechanism to explain the epidemiologic association. Additionally, the scientific literature available on pacifier use focuses largely on the probable adverse effects.

Obstructive sleep apnea (OSA) is a prevalent sleep related breathing disorder characterized by repetitive collapse of the upper airways leading to intermittent hypoxia and sleep disruption. Clinically relevant neurocognitive, metabolic and cardiovascular disease often occurs in OSA. Systemic hypertension, coronary artery disease, type 2 diabetes mellitus, cerebral vascular infarctions and atrial fibrillation are among the most often cited conditions with causal connections to OSA.

Obstructive sleep apnea (OSA) is a chronic and heterogeneous disorder that leads to early mortality, stroke, and cardiovascular disease (CVD). OSA is defined by the apnea-hypopnea index, which is an index of OSA severity that combines apneas (pauses in breathing) and hypopneas (partial obstructions in breathing) associated with hypoxemia. Yet, other sleep metrics (i.

Article Synopsis
  • - The study aimed to investigate whether obstructive sleep apnea syndrome (OSAS) is linked to the progression of glaucoma and how the severity of OSAS impacts the loss of visual field (VF).
  • - After analyzing 141 patients with both OSAS and glaucoma, only 25 were enrolled, revealing that 44% of eyes were "progressors" with more severe initial VF loss, but age and other factors were similar between progressors and non-progressors.
  • - Ultimately, the findings indicate no significant relationship between OSAS and glaucoma progression, as there was no correlation between the severity of OSAS and the rate of VF loss.
