Background: Pneumatic tube transport of blood gas samples is a common method of delivery within a facility. The effects of pneumatic tube transport on blood gas analysis has been studied. However, other analytes that are often assessed in blood gas analysis (eg, electrolytes, metabolites, and oximetry) are not typically included in these studies.

Background: Task interruptions are accident contributors in numerous industries. Recently, studies on health care interruptions and their impact on patient hazards have received attention.
Background: Arterial puncture for blood gas analysis is a common procedure in hospitals. The aim of the study is to determine if standardizing technique elements of the arterial puncture process could improve the success rate of technicians through the full scope of an academic medical center.
Methods: The study is conducted by the Blood Gas Laboratory at University of Utah Health's main campus.
Objectives: To determine the impact of systemwide charge display on laboratory utilization.
Methods: This was a randomized controlled trial with a baseline period and an intervention period. Tests were randomized to a control arm or an active arm.
Background: Phlebotomy is a significant cause of iatrogenic anemia in the critical care environment. It is estimated that one-third of all transfusions of packed red blood cells in intensive care units (ICU) result from phlebotomy. The aims of this study were to determine if utilizing the 1mL blood gas syringe for an adult population would impact the rate at which specimens were acceptable for testing and result reporting based on lab specimen rejection criteria; and to compare blood utilization between the 2 different syringes.
