Efficacy of PAP Therapy on Blood Pressure

April 14, 2015 updated by: Izolde Bouloukaki, University of Crete

The Role of Compliance With Positive Airway Pressure Use on Blood Pressure in Patients With Obstructive Sleep Apnea

The aim of the study was to determine the long term effects of compliance with positive airway pressure therapy on blood pressure in both hypertensive and normotensive patients with obstructive sleep apnoea hypopnoea syndrome.

Detailed Description

Scientific data about the causal role of obstructive sleep apnoea hypopnoea syndrome (OSAHS) in the development of systemic hypertension and the effects of positive airway pressure (PAP) treatment on blood pressure (BP) control are continuously increasing; however they are controversial. We aimed to determine the long term effects of compliance with PAP therapy on BP in both hypertensive and normotensive patients with OSAHS.

How is the study designed?

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: positive airway pressure (PAP)
Treatment with positive airway pressure (PAP)
Device: positive airway pressure (PAP)
Positive Airway Pressure (PAP) is a non-invasive machine providing air pressure f to prevent the collapse of the oropharyngeal walls and the obstruction of airflow during sleep, which occurs in obstructive sleep apnea hypopnea syndrome.
