Embodiments of the present invention relate to a system and method for determining a physiologic parameter of a patient. Specifically, embodiments of the present invention include methods and systems for correcting a pulse oximetry plethysmographic waveform variability measurement based on parameters that may influence the waveform variability. The corrected measurement may be used to estimate intravascular blood volume and/or fluid responsiveness of a patient.

Medical device for assessing intravascular blood volume and technique for using the same

A physiologic condition sensor comprises a sensor body including an optical assembly housed in a sensor housing. The optical assembly is configured to include a head portion, a tail portion, and an intermediate portion connecting the head portion and tail portion. The head and tail portions are wider than the intermediate portion to prevent longitudinal deformation of the sensor housing around the optical assembly.

Pulse oximetry sensor

An electrocardiogram (ECG) electrode patch for attachment to a neonatal or infant patient. The ECG electrode patch includes a plurality of at least three electrodes coupled to a substrate. The plurality of at least three electrodes includes at least one electrode capable of measuring the electrical activity of the right side of the patient's heart. A plurality of electrical conductors are coupled to the plurality of electrodes and to the substrate.

Electrocardiogram electrode patch

A flexible multiple electrode assembly includes at least one fixed electrode; at least one extendible electrode; and electrically conductive interconnections coupling the at least one fixed electrode and the at least one extendible electrode to a common connector. The at least one extendible electrode is adapted to be physically separable from the at least one fixed electrode while remaining electrically coupled to the common connector. In one embodiment, an array of fixed and extendible electrodes is configured for the acquisition of electrical pulses from a heart for transmission to an electrocardiograph (EKG or ECG) device.
