Sleep-disordered breathing (SDB)

Sleep disordered breathing (SDB) describes a group of disorders characterised by:

  1. Abnormal respiratory patterns (e.g. the presence of apnoeas or hypopneas); or
  2. Insufficient ventilation during sleep.

An apnoea is when a patient stops breathing for 10 seconds or more, and they wake up just enough to take a breath.

A hypopnea is when a patient doesn't stop breathing, but the patient's breathing becomes shallow (i.e., at least a 30% decrease in airflow) for 10 seconds or more, with an associated oxygen desaturation or arousal.

Either way, sleep disordered breathing disrupts the patient's sleep pattern, night after night, which not only makes the patient tired and exhausted the next day, but may also put excessive strain on the their nervous system and major organs.

All about sleep studies

During a sleep study, your patient's breathing is monitored to see if they have a sleep disorder such as sleep apnoea. Sleep studies can be done at home or in a sleep lab.

Equipment replacement

Learn how to educate your patients on the importance of timely equipment replacement and how critical it is to the success of their sleep apnoea therapy.
