Obstructive sleep apnea syndrome: evaluation of subcritical continuous positive airway pressure

Twenty eight of 48 patients diagnosed of obstructive sleep apnea syndrome over a six month duration opted for CPAP therapy. Half of them were given critical CPAP (Group A) and other half were prescribed subcritical level of CPAP (Group B). Re-evaluation after 3 months revealed that side effects like headache and feeling of inconvenience were more in Group A, though beneficial effects were same in both groups. It is concluded that subcritical level of CPAP should be adopted to treat patients of obstructive sleep apnea syndrome.
