WebbThe Low Flow PV Loop in the Evita Infinity® V500 serves as an automatic lung recruitment maneuver and can be used to optimize ventilator settings7). You can set start pressure, … Webb3 nov. 2024 · PV is the way to define the storage data, such as storage classes or storage implementations. Unlike ordinary volumes, PV is a resource object in a Kubernetes cluster; creating a PV is equivalent to creating a storage resource object. To use this resource, it must be requested through persistent volume claims (PVC).
