Non-invasive ambulatory blood pressure monitoring: effect on nocturnal sleep of children and adults.
OBJECTIVE: To investigate whether disturbance of sleep by ambulatory blood pressure monitoring determinations might result in altered blood pressure. METHODS: Ninety-seven subjects (29 children and 68 adults) attending an outpatient chronobiology center wore wrist actigraph motion detectors for 48 h (24 h before ambulatory blood pressure monitoring and 24 h during ambulatory blood pressure monitoring). Sleep variables including sleep efficiency, sleep latency, total time in bed, total sleep time, total minutes awake plus number and average duration of awakenings were derived by a dedicated algorithm. RESULTS: Comparison of the sleep variables for the baseline and ambulatory blood pressure monitoring nights revealed no differences in any of the sleep parameters either in the adults or in the children. Small differences between adults and children during the baseline and monitoring nights for some variables were most likely age- and disease-related. CONCLUSION: Non-invasive ambulatory blood pressure monitoring by the SpaceLabs model 90207 device at hourly intervals during night-time sleep does not significantly affect sleep either in children or adults.
