The diagnosis of OSA is based on the number of apneic or hypopneic episodes per hour of sleep, a measure called the apnea hypopnea index (AHI) (Kryger et al., 2011).
If patient has a hypopneic breathing pattern defined as a resting tidal volume of less than 7 ml/kg, then hyperinflation technique will be used to deliver aerosol medication using an Ambu bag.
Apneas were classified as obstructive if the chest and the abdominal wall movements continued during the apneic and hypopneic episodes.
Results include the apneahypopnea index or the respiratory disturbance index (number of apneic or hypopneic episodes per hour).
This machine defines an apneic event as a cessation of nasal airflow for 10 seconds or longer and a hypopneic event as a 50% reduction in nasal ventilation.
OSAS was defined as the presence of sleep apnea symptoms and a respiratory disturbance index (RDI) of 10 or more on polysomnography (PSG), as evaluated by standard criteria [8]; RDI is calculated by averaging the number of apneic and hypopneic events per hour of sleep.
