Emergency Medical Services Responder Manual Ventilation Performance.

Objective: Manual ventilation is a basic skill that every emergency medical services (EMS) responder is expected to perform proficiently. Improper manual ventilation may result in significant morbidity; however, there is no feedback mechanism or method of control for the volume, pressure, or frequency during manual ventilation. In this study, we aimed to quantify the volume and peak pressures of manually delivered breaths using a simulated lung.

In vivo pharmacokinetic features, toxicity profile, and chemosensitizing activity of alpha-cyano-beta-hydroxy-beta- methyl-N-(2,5-dibromophenyl)propenamide (LFM-A13), a novel antileukemic agent targeting Bruton's tyrosine kinase.

The purpose of the present study was to examine the in vivo pharmacokinetics and activity of alpha-cyano-beta-hydroxy-beta-methyl-N-(2,5-dibromophenyl)propenamide (LFM-A13), a novel antileukemic agent targeting Bruton's tyrosine kinase (BTK). We have applied an analytical high-performance liquid chromatography method for the quantitative detection of LFM-A13 in plasma samples. Our findings indicate that LFM-A13 is quickly absorbed, with the time required to reach the maximum plasma drug concentration (t(max)) being 10-18 min after i.
