Currently, sleep disorders, especially sleep apnea (OSA), are very common
in patients with chronic obstructive pulmonary disease (COPD), and
respiratory polyangiography is an effective exploratory technique in
diagnosing these disorders. With the goal of describing the results of
respiratory polygraph and evaluating the association with several clinical and
subclinical characteristics in patients with COPD GOLD E, we conducted a
cross-sectional descriptive studied on 59 COPD patients who were measured
by respiratory polygraphy at the Respiratory Center of Bach Mai Hospital,
obtaining the following results: 48/59 patients (81.4%) had OSA and COPD
overlap syndrome (OS), the average AHI was 22.5 ± 17.7. BMI, neckline,
abdominal circumference, Epworth score, STOPBANG score, and
Mallampati score were significantly higher in the OS group compared with
the COPD group (p<0.05). There was no significant difference in the two
groups when comparing age, sex ratio, %FEV1, and frequency of
comorbidities (p>0.05). Patients with COPD alone have respiratory and sleep
disorders, but when combined with OSA, these disorders are exacerbated.
BMI, neckline, abdominal circumference, Epworth score, STOPBANG
score, Mallampati score are predictors of OSA in COPD patients.
