WebWith the advent of rapid-responding pH and reference electrodes coupled to sensitive pH meters, these changes in H + ion concentration could be accurately measured. That measurement, which can be performed either directly or indirectly, forms the underlying principle upon which the electrometric methods for the assay of CA activity are built. WebpH-stat management was associated with fewer metabolic derangements and improved survival after 75 minutes of DHCA at 18°C, when compared with α-stat.1 In a study involving DHCA in piglets, improved cerebral oxygenation by near infrared spectroscopy, improved short term neurological performance, and concrete with wwm https://daisybelleco.com
