Current Sensing Amplifier for CPAP

CPAP stands for "Continuous positive airway pressure." The CPAP is a very beneficial treatment for those with sleep apnea, which is a medical condition where the airway closes off when an affected individual is in a relaxed or sleep state. CPAP therapy holds the airway open so that uninterrupted breathing is maintained and a restful night's sleep is achieved...
