Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, incorrect connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if reverse flow conditions or other error conditions exist. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The methods can be implemented at the humidifier side, at the gases source side, or both.

Abstract: Techniques for implementing a last known good (LKG) client-side cache for DNS resiliency are disclosed. A first DNS request is submitted to a DNS server. A first DNS resolution that resolves an IP address for a domain name is received. A service stores the first DNS resolution in an LKG cache residing on the local host. A second DNS request is sent, where the second DNS request again requests to resolve the same domain name. In response to determining that a second DNS resolution for the second DNS request has not been received, the service obtains the IP address for the domain name from the LKG cache.

Abstract: Various control methods can indirectly determine incorrect connections between components in a respiratory therapy system. For example, errors in the connections can occur between a patient interface, a humidifier and/or a gases source. The methods can indirectly detect if a reverse flow condition exists or other error conditions. A reverse flow condition can occur when gases flows in a direction different from an intended direction of flow. The detection of the reverse flow condition can be indicative of likely errors in connections between the humidifier, patient interface and/or gases source.

Abstract: Moisture conditions in a conduit, particularly a gases supply system conduit for supplying respiratory or surgical gases, can be detected using an electrical property of the conduit. Moisture conditions can also be detected in another component of the gases supply system. The detected moisture conditions can be managed to reduce and/or remove excess moisture in the system.
