Symptomatology of obstructive sleep apnea syndrome patients and its correlation with Apnea Hypopnea index.

Dr Yadvir Garg, Dr Cds Katoch

Abstract :

The aim of this study was to characterize symptomatology of patients suffering from obstructive sleep apnea syndrome (OSAS) and investigate its correlations with severity of disease as assessed by apnea hyponea index (AHI) score.

Materials and methods:

All patients diagnosed to be having obstructive sleep apnea syndrome (OSAS) over a period of one year in tertiary care hospital were retrospectively studied. Symptomatology was recorded and sleepiness was measured quantitatively by Epworth sleepiness scale (ESS). Symptoms were correlated with AHI score using linear correlation for continuous variables and chi –square test for discrete variables.

Results :

Snoring was detected to be most common symptom, seen in 28/30 (93.3%) of patients. Breathing pauses(16/30 –53.3%) and witnessed choking(13/30– 43.3%) on correlation with AHI had p value of 0.039 and 0.046 respectively. ESS scores increased linearly with the AHI (correlation coefficient 0.501, P value 0.005)

Conclusion

Patients with complaints of choking and witnessed apneas are more likely to be suffering from Severe OSA. Raised values of ESS score also depict increased severity of disease in linearly
