Covestro polycarbonate selected for innovative airway monitoring device

Clearing the air


VentRight Monitor from Certus Critical Care aims to empower healthcare providers to manage patient-ventilator asynchrony. Makrolon® polycarbonate selected for biocompatibility and impact strength needed for this demanding application.


A common challenge in mechanical ventilation is maintaining synchrony between a patient’s respiratory demand and the ventilator's delivery of air. Patient-ventilator asynchrony (PVA) occurs frequently and can lead to ventilator-induced lung injury, patient discomfort, and may increase the risk of death.

Certus Critical Care is developing the VentRight Monitor (VRM), an airway monitoring medical device, to improve patient care in critical situations requiring mechanical ventilation. The VRM uses multiple sensors and advanced algorithms to accurately identify multiple types of PVA along with clinical decision support to assist providers in effectively managing these PVAs. By offering precise detection and monitoring, the VRM aims to empower healthcare providers in emergency departments, intensive care units and medical transport with the information needed to optimize patient care in real-time. For this innovative technology, Covestro is supplying Certus Critical Care with its Makrolon® 2458 polycarbonate, used in the water trap and airway chamber. Makrolon® 2458 offers biocompatibility and impact strength with the appearance of glass, which is necessary in critical care environments. Certus Critical Care also has plans for a supporting monitor, which will use Covestro material for its housing.

Makrolon® 2458 polycarbonate is a medical grade thermoplastic material that meets ISO 10993-1 and USP class VI. Available in transparent and translucent colors, this material offers biocompatibility and impact strength with the appearance of glass. Bayblend® M850 XF PC+ABS, a medical grade thermoplastic material, offers rugged durability and high chemical resistance for challenging medical environments.

“The VentRight Monitor is a technological advance that will help answer an unmet need in the healthcare market,” said Mark Nichols, Healthcare Key Account Manager, Covestro LLC. “We are working closely with Certus Critical Care to provide a high-quality, proven material that meets the rigorous requirements of this potentially life-saving product.”

Covestro was selected as a partner because of its reputation for producing high-quality, durable engineering plastics, according to Certus Critical Care. ”Their materials not only met but exceeded our needs for durability, resistance to sterilization processes, and compliance with biomedical standards,” said Jared Spendlove, Director of Operations and Manufacturing, Certus Critical Care.

“Utilizing Covestro's materials allowed us to design a product capable of withstanding the demanding conditions of critical care environments, providing a reliable tool for healthcare professionals, and setting a new standard in patient-ventilator monitoring.”

Attendees at MD&M West, February 6-8 in Anaheim, California, can visit the Covestro booth (#2221) to learn how the company’s materials are pushing boundaries in healthcare applications.
