Respiratory activation in patients with obstructive sleep apnea syndrome (OSA)

LI> reduced upper airway resistance in the recovery period indicated LTF of upper airway dilators;

  • lack of hyperpnea (breathing that is deeper and more rapid than is normal at rest) in the recovery period, suggesting that thoracic pump muscles do not demonstrate LTF;

  • LTF may temporarily stabilize respiration in OSA patients after repeated apneas/hypopneas; and

  • nasal CPAP did not alter the ability of OSA patients to elicit LTF at the thoracic pump muscle.
