Abstract:
The present disclosure includes a medical monitoring hub as the center of monitoring for a monitored patient. The hub includes configurable medical ports and serial ports for communicating with other medical devices in the patient's proximity. Moreover, the hub communicates with a portable patient monitor. The monitor, when docked with the hub provides display graphics different from when undocked, the display graphics including anatomical information. The hub assembles the often vast amount of electronic medical data, associates it with the monitored patient, and in some embodiments, communicates the data to the patient's medical records.
Abstract:
A method of storing streaming physiological information obtained from a medical patient in a multi-patient monitoring environment includes receiving identification information, retrieving parameter descriptors, creating a round-robin database file, receiving a data stream, and using a predetermined data rate to map the data stream to locations in the round-robin database file.
Abstract:
Automated critical congenital heart defect (“CCHD”) screening systems and processes are described. A caregiver may be guided to use a single or dual sensor pulse oximeter to obtain pre- and post-ductal blood oxygenation measurements. A delta of the measurements indicates the possible existence or nonexistence of a CCHD. Errors in the measurements are reduced by a configurable measurement confidence threshold based on, for example, a perfusion index. Measurement data may be stored and retrieved from a remote data processing center for repeated screenings.
Abstract:
An alarm notification system can enable a clinician to respond to an alarm notification received via a computing device, which may have more advanced functionality than a pager. The clinician's device can include a notification client which can respond to alarm notifications. The notification client can also provide one or more user interfaces that enable the clinician to view information about an alarm, such as information about a patient's status, physiological parameter values, trend data, audio/video of the patient, combinations of the same, or the like. Further, the notification client can provide functionality for a clinician to respond to an alarm, annotate an alarm, and/or indicate that the clinician can or cannot respond to the alarm, among other features. In addition, the clinician device can also (or instead) include an admit module that provides for automatic association of a patient to a device or location.
Abstract:
A portable spot-check system configured to assess the validity of a measured physiological parameter. The spot-check device can take into consideration a variety of factors to determine whether a valid measurement exists. For instance, the considerations can include signal stability, interference, signal IQ, patient movement, sensor position, timing of that measurement, comparison to previous or acceptable measurements, cancellation of measurement by the patient, confidence of the measurement, etc. The spot-check device can track a number of valid measurements. In some instances, the spot-check device is configured to provide a specified number of available measurements. If a valid measurement is recorded, the spot-check device can decrement the remaining number of available measurements.
Abstract:
This disclosure describes example alarm notification systems that can enable a clinician to respond to an alarm notification received via a computing device, which may have more advanced functionality than a pager. The clinician device may be a mobile device, such as a cellphone or smartphone, tablet, laptop, personal digital assistant (PDA), or the like. The clinician device may communicate with a remote server to obtain patient data generated by a patient device at the point-of-care (such as a bedside device or patient-worn monitor). This patient data may be continuous monitoring data for one or more patients. A mobile application (optionally a browser application) on the clinician device can enable the clinician to view continuous monitoring data for multiple patients, as well as view and respond to alarms and alerts, all from the clinician device, regardless of location.
Abstract:
A patient monitor can diagnose whether its speaker is blocked, malfunctioning, or at a volume that is too low. For example, the monitor can include a processor that can diagnose the speaker by recording a microphone input signal. The processor can compare the microphone input signal to an expected alarm signal that should be output by the speaker. If the two do not match or reasonably correspond to one another, then the processor may increase the volume of the alarm to determine whether doing so can overcome an obstruction, noise, or potential malfunction. The microphone can again detect the speaker output, and the processor can again make another comparison or analysis of the input with the speaker output. If the speaker output as detected via the microphone is still insufficiently loud, then the patient monitor may output an indication that the speaker has a problem.
Abstract:
A medical communication protocol translator can be configured to facilitate communication between medical devices that are programmed to communicate with different protocol formats. The medical communication protocol translator can receive an input message formatted according to a first protocol format from a first medical device and to output an output message formatted according to a second protocol format supported by a second medical device using a set of translation rules. For example, a medical communication protocol translator can receive an input message from a hospital information system formatted according to a first HL7 protocol format and output an output message formatted according to a second HL7 protocol format based on a comparison with the set of translation rules.
Abstract:
Medical monitoring systems and methods for reducing the frequency of notifications of transient alarms are disclosed. A medical monitoring system can collect a signal representative of the physiological condition of a patient and can determine a physiological parameter using the collected signal. The medical monitoring system can detect an alarm condition for the physiological parameter. The medical monitoring system can then delay notification of the alarm condition until it persists for a predetermined alarm notification delay time.
Abstract:
A device for obtaining physiological information of a medical patient and wirelessly transmitting the obtained physiological information to a wireless receiver.
