Details and patient eligibility

About

The diagnosis of OSASH requires expensive sleep tests that generate long waiting lists, so we need simplified and rapid diagnostic tools. The ApneaLinkTM, is a device that allows the assessment of respiratory events by measuring the flow ventilation with a nasal cannula connected to a pressure transducer.
