Intraosseous Pressure Monitoring in Healthy Volunteers.

Study Objective: Invasively monitoring blood pressure through the IO device has not been thoroughly demonstrated. This study attempted to establish baseline values of IO pressure in a healthy human population.

Methods: This was a prospective, healthy volunteer, observational study.

Characteristics of demand oxygen delivery systems: maximum output and setting recommendations.

Background: Demand oxygen delivery systems (DODS) allot oxygen by interrupting the oxygen flow during exhalation, when it would mostly be wasted. Because DODS conserve oxygen by various methods, there are important performance differences between DODS. We studied certain performance factors that have not previously been carefully examined.
