Pulse CO-oximetry (Rad-57; Masimo Corp, Irvine, CA) has been available since 2005. To date, all published clinical studies have focused on clinical reliability and whether the device enhances case finding through screening of various populations. This study examines whether use of pulse CO-oximetry shortens the time to diagnosis and treatment of patients with carbon monoxide (CO) poisoning. ⋯ Pulse CO-oximetry is associated with more rapid diagnosis and initiation of hyperbaric oxygen therapy in CO-poisoned patients compared with laboratory CO-oximetry. The impact on clinical outcome remains to be determined.

Blood-fluid level on computed tomography head: a sign of warfarin-associated intraparenchymal hemorrhage.
“Blood/fluid level” represents interface between the plasma and sedimented blood and is defined radiologically as presence of area of low computed tomography (CT) attenuation above and high CT attenuation below a discrete line of separation in an area of intraparenchymal hemorrhage. It is a rare finding seen in association with large clot volume of intraparenchymal hemorrhage. We present a case of warfarin-related intraparenchymal hemorrhage presenting with a classic sign of “blood/fluid level” on CT head with small clot volume.
