There are two types of sleep scoring techniques for evaluation of obstructive sleep apnea (OSA) on polysomnography, they are manual and automated scoring. Manual scoring with expert technician is considered as a gold standard scoring technique. It evaluates total sleep time, stage of sleep, and apnoea or hypopnea index (AHI) better than automated scoring. However, this technique needs more manpower, money, and infrastructure. Automated scoring technique is simple, cost effective, and less time consuming. Both techniques can be performed with home sleep testing or in laboratory polysomnography. Though, automated scoring technique is less accurate in diagnosis of mild form of OSA, it is a viable option for moderate and severe OSA especially where the patient load is high and facilities are limited.
