The Broselow tape is a length-based tool used for the rapid estimation of pediatric weight and was developed to reduce dosage-related errors during emergencies. This study seeks to assess the accuracy of the Broselow tape and age-based formulas in predicting weights of South Sudanese children of varying nutritional status. ⋯ The Broselow tape and age-based formulas selected for comparison were all markedly inaccurate in both the nonmalnourished and the malnourished populations studied, worsening with increasing malnourishment. Additional studies should explore appropriate methods of weight and dosage estimation for populations of low- and low-to-middle-income countries and regions with a high prevalence of malnutrition.

The objective was to assess whether respiratory depression and supportive airway measures occurring during procedural sedation are associated with changes in peripheral tissue oxygen saturation (StO2 ). ⋯ Patients with respiratory depression and the use of supportive airway measures had greater changes in StO2 during procedural sedation than in patients who did not. Peripheral tissue oxygen saturation monitoring may be a useful tool for assessing respiratory adverse events in patients undergoing procedural sedation in the ED.

Cardiac arrest is one of the leading causes of death in the United States and is treated by cardiopulmonary resuscitation (CPR). CPR involves both chest compressions and positive pressure ventilations when given by medical providers. Mechanical chest compression devices automate chest compressions and are beginning to be adopted by emergency medical services with the intent of providing high-quality, consistent chest compressions that are not limited by human providers who can become fatigued. Biosignals acquired from cardiac arrest patients have been characterized in their ability to track the effect of CPR on the patient. The authors investigated the feasibility and appropriate response of a biosignal-guided mechanical chest compression device in a swine model of cardiac arrest. ⋯ In this proof-of-concept study, a signal-guided chest compression device was demonstrated to be capable of responding to biosignal input and delivering chest compressions with a broad range of rates and depths.
