Abstract: Systems, apparatuses, and methods provide for determining whether an arterial blood pressure signal damping event is occurring and automatically flushing a catheter tubing in response to a determination that the arterial blood pressure signal damping event is occurring. In one example, the determination whether an arterial blood pressure signal damping event is occurring is based on a specific pattern change of the arterial blood pressure signal within a specified time window and beyond one or more specified threshold values. Additionally, or alternatively, a determination may be made as to whether the arterial blood pressure signal damping event is resolved in response to the automatic flush of the catheter tubing based on the arterial blood pressure signal.

Abstract: A technique for collecting environmental data from a remote region comprises use of a collector device with a sensor to collect environmental data and a memory to store the collected data. Collector devices are distributed to locations within the region, and the collector devices collect and store environmental data. Locations within the region are prioritized. Incentives are generated to transport environmental data based, at least in part, on the priorities. When a collector device is transported from the remote region to a location with connectivity to a host system, the stored environmental data is uploaded.

Abstract: Electrocardiography (ECG or EKG) is a technique where electrodes are attached to the outer surface of the patient's skin at certain places on the patient's torso in order to monitor the electrical activity of the heart. The electrodes are connected by lead wires to an external device, which records the electrical activity of the heart over a period of time as detected by the electrodes and produces an electrocardiogram. Proper electrode placement is essential to measure the heart's electrical activity accurately and diagnose and interpret cardiac abnormalities. However, improper positioning or placement of the electrodes, including accidental interchanging of electrodes, are common technical mistakes that negatively impact signal quality and usefulness. Accordingly, provided herein are augmented-reality systems and methods of providing real-time guidance in placing one or more electrocardiogram electrodes on a subject and verification of such placements.

Abstract: Methods and systems for intraoperatively determining alignment parameters of a spine during a spinal surgical procedure are disclosed herein. In some embodiments, a method of intraoperatively determining an alignment parameter of a spine during a surgical procedure includes receiving initial image data of the spine including multiple vertebrae and identifying a geometric feature associated with each vertebra in the initial image data. The geometric features each have a pose in the initial image data and characterize a three-dimensional (3D) shape of the associated vertebra. The method further comprises receiving intraoperative image data of the spine and registering the initial image data to the intraoperative image data. The method can then update the pose of each geometric feature based on the registration and the intraoperative image data, and determine the alignment parameter based on the updated poses of the geometric features associated with two or more of the vertebrae.
