A cause of daytime sleepiness due to an inherited disorder of the control of dreaming sleep. Has to be differentiated from sleep apnoea, periodic leg movements and other rarer causes of daytime sleepiness.
The process of delivering a continuously raised airway pressure via a mask on the nose.
NASAL CPAP SYSTEM
Mask – Consisting of three main types, nasal pillows, nasal mask and full face mask
Nasal Pillows – sits under the nose with short pillow protrusions into the nasal passages, that inflate slightly due to the slight increase in air pressure once the pump starts
Nasal Mask – fits over the nose on a cushion, that is sealed by the slight increase in air pressure once the pump starts
Full Face Mask – Covers the nose and mouth on a cushion that is sealed by the slight increase in air pressure once the pump starts.
Pump or blower – main unit developing the pressure. Ramp – the slow rise to full pressure after first turning on the machine, available from some manufacturers.
NASAL INTERMITTENT POSITIVE PRESSURE VENTILATION (NIPPV)
The same as BiPAP (this is a brand name like Hoover).
One of the best predictors of whether there are upper airway problems during sleep. More than 16″ – could be a snorer, more than 17″ could have sleep apnoea. One can still have sleep apnoea with smaller necks but it is less common.
Baby less than a month old.
