Think heliox

Today’s respiratory therapists should remain knowledgeable about heliox and how it can be adapted for use in patients with moderate to severe airway obstruction, argues Tina Pitt, BPS, MPS, RRT, RRT-NPS, Le Bonheur Children’s Hospital in Memphis, in a recent issue of AARC Newsroom. Pitt cites a successful case of heliox use administered to an infant through high-flow nasal cannula in severe acute respiratory distress syndrome (ARDS) caused by COVID-19.

Smart suture for deep surgical sites

Researchers at the National University of Singapore have developed a smart suture that is battery-free and can wirelessly sense and transmit information from deep surgical sites. The suture incorporates an electronic sensor that can monitor wound integrity, gastric leakage and tissue micromotions while providing healing outcomes that are equivalent to medical-grade sutures. During the stitching of the wound, the insulating section of the suture is threaded through the electronic module and secured by applying medical silicone to the electrical contacts. The entire surgical stitch then functions as a radio-frequency identification (RFID) tag and can be read by an external reader, which sends a signal to the smart suture and detects the reflected signal. A change in the frequency of the reflected signal indicates a possible surgical complication at the wound site.

EUAs after the emergency

The U.S. Food and Drug Administration is proposing that it give medical device makers half a year’s notice before terminating emergency use authorizations (EUAs) post-pandemic, reports Mass Device. The FDA said its draft guidance on the topic is intended to help manufacturers prepare for an orderly and transparent transition to the eventual resumption of normal operations in a post-pandemic world, and proposed that the agency publish the advance notice of termination of each EUA declaration 180 days before it is officially terminated.

RTs and advanced diagnostic bronchoscopy

Respiratory therapists should view advanced diagnostic bronchoscopy as an opportunity for the profession to train, develop and lead the path forward, says Jaspal Singh, MD, MHA, MHS, FCCP, FCCM, FAASM, professor of medicine at Carolinas Medical Center and Atrium Health in Charlotte, North Carolina, in the Dec. 29 issue of the AARC Newsroom. Technological advances (e.g., linear and radial endobronchial ultrasound, new-generation bronchoscopes, adjunctive imaging modalities) as well as evolving anesthesia and sedation practices for bronchoscopy are driving the volume and breadth of work in bronchoscopy.
