Comparison of supplemental oxygen delivery by continuous versus demand based flow systems in hypoxemic COPD patients - A randomized, single-blinded cross-over study.

Background: Supplemental oxygen is a recommended therapy option in stable hypoxemic COPD patients. Often, supplemental oxygen is provided by continuous flow (CF). However, demand oxygen delivery systems (DODS) that provide an oxygen bolus only during inspiration have gained increasing use as they prolong oxygen cylinder life (beside battery life).

Long-Term Follow-Up of Children after Venom Immunotherapy: Low Adherence to Anaphylaxis Guidelines.

Background: Data on the long-term outcome of children after specific venom immunotherapy (VIT) are limited. Therefore, we assessed sting recurrence and anaphylaxis relapse rates as well as adherence to anaphylaxis guidelines with regard to the availability of emergency equipment and education status.

Methods: For this long-term survey, data of 311 children with a history of anaphylactic reactions to hymenoptera stings were collected by chart review.
