摘要： A cardio-pulmonary resuscitation apparatus and method that provides mechanical compressions and oxygen delivery to a patient. The delivered oxygen quantity is based on the anterior to posterior distance of the patient. Tidal volumes of the delivered oxygen are calculated from the anterior to posterior distance. The compressions and oxygen may be delivered in sequences that enhance the circulation of the patient. The compressions may be sensed by a sensor to effect such sequences. Oxygen delivered based on the anterior to posterior distance may be further adjusted by airway pressure. Embodiments may include a tube with lumens to deliver oxygen, monitor airway pressure, and contain wires to activate the airway valve and monitor airway pressure. Embodiments may also include a carbon dioxide sensor and may use two tidal volumes, the larger one to sample the end tidal carbon dioxide. Also included in some embodiments is a safety relief valve.

摘要： A cardio pulmonary CPR device and method that provides enhanced circulation by an optimal combination and sequencing of maximal positive and maximal negative intrathoracic pressures, while maintaining a degree of passive ventilation to the patient. Namely, the embodiments of the invention provide for an optimal positive thoracic pressure compression state, with passively or actively filled lungs, achieved by either passive chest recoil with an open airway, or an active inflation mechanism. Said embodiments also provide for an optimal negative pressure decompression state, combined with actively emptied lungs (by chest compression).

摘要： Various different implementations of lead systems are disclosed for use with implantable stimulation systems. Generally, the lead systems incorporate, within an elongate lead body, one or more electrical conduits that connect to one or more distal electrodes, and a liquid-filled pressure transmission catheter lumen that extends proximally from a distal entry port. Use of the lead systems allows accurate pressure sensing at a location near where the electrodes are positioned. In addition, a defibrillator lead is disclosed having such features, and a system using that lead is capable of directly monitoring pressure within a heart chamber, and using that information to confirm the delivery of a defibrillation pulse.

摘要： Electrodes of a subcutaneous monitoring system receive body electrical signals that indicate both cardiac and non-cardiac muscle activity. In general, non-cardiac muscle activity is often correlated with physical activity, and physical activity is typically a strong indicator of patient health. Exemplary systems and methods that detect non-cardiac muscle activity information in sensed body electrical waveforms may provide a diagnostic tool for monitoring physical activity level over time in patients that have subcutaneous monitoring systems. In an illustrative embodiment, systems and methods for presenting patient activity information in a graphical format over intervals of time include processing ECG waveform information to identify and to accumulate non-cardiac muscular activity information during each of the intervals of time. In various implementations, number, intensity, and/or duration of the events that are identified during a time interval may be accumulated and stored for subsequent recall.
