Abstract

Quality of chest compressions (CC) is an important determinant of resuscitation outcome for cardiac arrest patients. To characterize the quality of CC performed by hospital personnel, evaluate for predictors of CC performance, and determine the effects of audiovisual feedback on CC performance. Seven hundred and fifty four individuals participated in a CPR quality improvement challenge at 30 US hospitals. Participants performed 2min of CC on a manikin with an accelerometer-based system for measuring both rate (CC/min) and depth (in.) of CC (AED Plus:ZOLL Medical). Real-time audiovisual feedback was disabled. A subset of participants performed a second trial of CC with the audiovisual feedback prompts activated. Mean depth of CC was below AHA minimum guidelines (<1.5in.) for 34% (1.30+/-0.14in.) and above maximum guidelines (>2.0in.) for 12% of participants (2.20+/-0.22in.). Depth of CC was greater for male vs. female (p<0.001) and younger vs. older (p=0.009) but did not differ between ACLS, BCLS, and non-certified participants (p=0.6). Predictors of CC depth included CC rate (r(part)=-0.34, p<0.0001), gender (r(part)=0.13, p=0.001), and age (r(part)=-0.09, p=0.02). Mean depth of CC increased, mean rate decreased, and variance i...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
