Embodiment Construction

[0013] Various sensors, such as PPG sensors, can be used to detect patient vital signs, such as the patient's pulse and / or SpO 2 Absence / Presence of CPR, and monitor the patient's pulse rate during CPR. However, CPR techniques may require chest compressions to be performed. Movement of the patient's body caused by chest compressions can make noninvasive detection of reliable ROSC difficult, and interruption of chest compressions for accurate detection of ROSC can increase the likelihood of negative outcomes. Accordingly, Applicants have recognized and appreciated that it would be beneficial to provide techniques and devices that assist in detecting and / or monitoring a patient's vital signs during the performance of CPR. In view of the foregoing, various embodiments and implementations of the present invention relate to apparatus and methods for detecting vital signs of a patient during the performance of CPR.

Abstract

In various embodiments, an apparatus to aid in cardiopulmonary resuscitation ("CPR"), may include: a support structure (200, 300, 400) shaped to support a head and neck of a patient at respective positions suitable for opening an airflow of the patient during performance of CPR on the patient; one or more electromagnetic radiation sources (208, 308, 408) mounted on the support structure to emit electromagnetic radiation having a wavelength within a predetermined frequency range of wavelengths onto skin of the patient; and one or more electromagnetic or optical sensors (210, 310, 410) mounted on the support structure to detect electromagnetic radiation within the predetermined frequency range that is reflected from or transmitted into the patient's skin.

Description

technical field [0001] The present invention generally relates to health care. More specifically, various inventive methods and devices disclosed herein relate to detecting one or more of a patient's vital signs during the performance of cardiopulmonary resuscitation ("CPR"). Background technique [0002] Cardiopulmonary resuscitation ("CPR") is an emergency procedure performed on a patient in sudden cardiac arrest in an effort to create artificial circulation (ie, by manually pumping blood through the heart). CPR may be performed until further measures are taken to restore spontaneous blood circulation and breathing. CPR techniques may involve performing chest compressions of various magnitudes, such as at least 5 cm (2 in) deep, at various intervals, such as at least one hundred times per minute. In some instances, CPR may be discontinued when return of spontaneous circulation ("ROSC") is detected. Various tactile sensors, such as photoplethysmography ("PPG") sensors, c...
