Described herein are methods, devices and systems for predicting ventilator associated pneumonia (VAP). In an example, data of a patient including one or more features useful in predicting VAPs are accessed and the features are extracted. A model is activated based on a time parameter associated with mechanical ventilation or length of stay in ICU. The extracted features are evaluated automatically by the activated model to determine a probability that a VAP will occur. If it is determined, based on the evaluating, that a VAP has a probability of occurring that exceeds a threshold, an indication that the VAP is predicted to occur may be provided. Other examples are disclosed and claimed.

This invention provides an antibacterial and anti-adhesion double-balloon tracheostomy cannula and its preparation method. The invention involves constructing a coating material co-loaded with a newly developed tetradecyl antibacterial agent and chondroitin sulfate on both the cannula's surface and inner wall. This coating possesses both excellent hydrophilicity and strong antibacterial properties. The hydrophilicity makes it difficult for secretions to adhere; the antibacterial properties kill bacteria through contact, minimizing the development of drug resistance; and the anti-adhesion properties reduce the basis for biofilm formation. These three properties work synergistically to achieve full-chain protection from the "source" to the "process," significantly reducing the risk of luminal obstruction and VAP (ventilator-associated pneumonia), while also reducing the frequency of suctioning and mucosal damage, thus improving patient comfort.
