Abstract:
A movement sensitive mattress (2) is disclosed that has a plurality of independent like movement sensors (5) for measuring movement at different locations on the mattress to generate a plurality of movement signals. The signals are processed to derive respiratory variables including rate, phase, maximum effort and heartrate. Such variables can be combined to derive one or more diagnostic variables including apnea and laboured breathing classifications.
