 Portable respiratory monitoring (PM) has been used to diagnose obstructive sleep apnea (OSA) in the general population. However, its validation in patients with both OSA and chronic obstructive pulmonary disease (COPD), remains unclear.  The aim of the study was to validate PM for the diagnosis of OSA in patients with COPD.

Sleep is essential for the proper functioning of all individuals. Sleep-disordered breathing can occur at any age and is a common reason for medical visits. The objective of this consensus is to update knowledge about the main causes of sleep-disordered breathing in adult and pediatric populations, with an emphasis on obstructive sleep apnea.

Article Synopsis
  • The study evaluated arterial stiffness, indicated by pulse wave velocity (PWV), in patients with COPD and those with both COPD and obstructive sleep apnea (OSA), referred to as overlap syndrome (OS).
  • A total of 102 COPD patients were analyzed, with 51 having OSA; both groups were similar in age and airflow limitation, but the OS group had a higher percentage of men.
  • The findings showed that high PWV values were common in both groups, but there were no significant differences in PWV, blood pressure, or other vascular measures between the COPD alone and the COPD with OSA groups.

Article Synopsis
  • The study aimed to assess factors leading to poor sleep quality among COPD patients, both with and without obstructive sleep apnea (OSA).
  • Researchers evaluated 102 stable COPD patients using tools like polysomnography and the Pittsburgh Sleep Quality Index, identifying predictors of poor sleep through logistic regression analysis.
  • Results showed that 74.8% of participants experienced poor sleep quality, with significant associations found with severe COPD (GOLD grade C/D), higher COPD Assessment Test scores, and low oxygen saturation levels, while OSA did not affect subjective sleep quality.

Objective: To evaluate the construct validity and reproducibility of the six-minute step test (6MST) in individuals with obstructive sleep apnea (OSA) treated with continuous positive airway pressure (CPAP).

Methods: We evaluated 48 volunteers diagnosed with OSA and treated with CPAP for at least two months. The volunteers underwent the six-minute walk test (6MWT) and the 6MST, in random order and on different days, with an interval of, at most, seven days between the two tests.

Objective: To evaluate lung function and inspiratory muscle strength, correlating them with exercise tolerance, in obese individuals with obstructive sleep apnea syndrome (OSAS).

Methods: The sample comprised 31 adult subjects with moderate-to-severe OSAS diagnosed by polysomnography. We used spirometry to measure FVC, FEV1, and FVC/FEV1 ratio, using pressure manometry to measure MIP and MEP.

Objective: To determine the efficacy of using forced expiratory volume in six seconds (FEV6) as a surrogate for forced vital capacity (FVC) in the diagnostic screening for chronic obstructive pulmonary disease (COPD) by comparing FEV1/FVC ratios with FEV1/FEV6 ratios.

Methods: In November of 2003, on World COPD Day, we conducted a campaign of diagnostic screening for COPD. The participants completed the clinical questionnaire of the Global Initiative for Obstructive Lung Disease, and those who responded affirmatively to at least three questions underwent spirometry.
