aScope Broncho Supporting Evidence
There are many reasons why choosing a single-use bronchoscope is beneficial — to the clinician, to the practice and, ultimately, to the patient. Our aScope™ Broncho Evidence Dossier explores the many health outcomes such as contamination and infection, health economics, product performance, and more. Just open one of the sections below to review full text and abstracts with links to their initial publication and research.

Experience with the use of single-use disposable bronchoscopes in the ICU in a tertiary referral center of Singapore
Marshall, D., et al.
The use of a single-use bronchoscope in the ICU led to a reduction in the number of staff required to perform a bronchoscopy, shorter time between identifcation of bronchoscopy need and procedure start, and reduced the use of resources.
