Effect of laryngeal mask airway insertion on parameters derived from catacrotic phase of photoplethysmography under different concentrations of remifentanil 150 150 IEEE Journal of Translational Engineering in Health and Medicine (JTEHM)

Background: Some parameters have been extracted from photoplethysmography (PPG) with a good relativity with nociception, but without encouraging results in qualifying the balance of nociception-anti-nociception (NAN). The features of PPG…
