IR Thermal Imaging for Apnea Detection
November 7Just when we discussed how effective respiratory flow sensors are in detecting apnea events, along comes a new method using thermal imaging. An infra-red camera is placed near the bed and records airflow via thermal imaging (it ’sees’ the heat produced by exhalations) to determine breathing interruptions.
Initial tests confirm this method’s accuracy and the fact that it’s a non-contact way of apnea event detection, this solution could be a break through in screening and diagnosis. A no-wires approach means your sleep lab visit isn’t hampered by getting tangled or wearing recording devices.
