    Abstract: Systems, apparatuses, and methods directed to the collection and analysis of data related to a patient during an emergency advanced airway management process. The collected data may be obtained using various types of sensors, with the data collection process being managed or coordinated by a suitable system, such as a combination monitor-defibrillator. The monitor-defibrillator (alone or in combination with other system elements, such as a wired or wireless communications capability, a processor, data storage, etc.) may include a capability to process some or all of the acquired data, and in response indicate to a user when some of the collected data may be unreliable.

    Abstract: A remote patient monitoring system having a main patient monitor and a remote patient monitor. The main patient monitor is configured to receive and collect one or more patient physiological parameters and to provide an alarm in response to an alarm trigger. The alarm trigger includes a determination that at least one of the collected patient physiological parameters has reached a predetermined value. The remote patient monitor has an alarm reset and is configured to be carried by a caregiver. It is also configured to receive a signal from the main patient monitor in response to the alarm and to transmit an indication about the alarm trigger. The indication includes one or more of a notification that the patient is being attended to, a request by the caregiver for additional help, or a message about resolution of the alarm trigger.

    Abstract: Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.

    Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received, derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. In some embodiments, a penalty value can be determined for at least one of the pauses, from at least one control factor unrelated to a constant linear dependence on the pause duration. An indicative value can be derived from the penalty value. In some embodiments, at least some of the pauses are classified in one or more pause groups, depending on how well they meet one or more classification criteria. The indicative value can be derived for one of the pause groups. The indicative value can be output, and/or an alarm can be emitted if it exceeds a threshold. CPR quality assessment can be improved in real time, and provide feedback for training.

    Abstract: In embodiments, an external medical device is intended to care for a patient. If it receives an input that signifies that ventilation artifact is present in a signal of the patient, it transmits a corrective signal responsive to the received input. In further embodiments, a patient signal is received, which is generated from a patient while the patient is or was receiving chest compressions at a frequency Fc, and also receiving ventilations at frequency Fv. At least one filter mechanism may be applied to the patient signal to substantially remove artifacts at a) frequency Fc, b) a higher harmonic of frequency Fc, and c) a third frequency substantially equaling frequency Fc plus or minus frequency Fv, while substantially passing other frequencies between them. As a result, the patient signal can be cleaner, for diagnosing the patient's state more accurately.
