Sleep Apnea & Respiratory Function
- During ageing, both quality and quantity of sleep decline, contributing to reduced quality of life, obesity, hypertension, diabetes, glucose intolerance, metabolic syndrome and heart disease.
- Obstructive sleep apnea (OSA) is characterised by fragmentation and increased respiratory events including apneas with hypoxemia.
- 8 weeks of respiratory muscle training (RMST) decreased number of awakenings, apnea and hypopnea, and desaturation on REM and NREM sleep in older persons with OSA.
Sleep parameters included:
- Sleep time
- Sleep onset
- Sleep perception
- REM latency
- Leg movements
- Apnea and hypopnea
- NREM sleep
RMST significantly decreased number of awakenings, apnea and hypopnea, as well as desaturation of REM and NREM sleep.
RMST significantly improves sleep quantity and quality, with a severe reduction in apnea in older patients with sleep disorders.
