Provided herein is technology relating to medical monitoring of physiologic parameters, and particularly, but not exclusively, relating to compositions, methods and systems for the measurement of venous and arterial oxygen saturation in the blood of blood-filled anatomical structures.

Compositions and methods for measurement of oxygen saturation in blood filled structures

An esophageal stethoscope includes a tubular flexible body having an acoustic input region. A carrier member, which is separate from the tubular flexible body, is selectively engageable with the tubular flexible body either proximally or distally of the acoustic input region. The carrier member carries one or more devices for providing esophageal recording, monitoring or stimulation functions. For transesophageal cardiac pacing, electrodes are mounted to the carrier member such that engagement of the carrier member with the tubular flexible body functions to convert the esophageal stethoscope to a pacing stethoscope. To carry out a sensing, recording or monitoring function, such as esophageal oximetry, one or more oximetry probes are mounted to the carrier member such that engagement of the carrier member with the esophageal stethoscope converts the stethoscope for use in an oximetry sensing application. A 'universal' stethoscope includes engagement structures at predetermined locations along the length of the tubular flexible body, for use in engaging a stimulation carrier and/or a recording/monitoring carrier with the esophageal stethoscope.

Carrier for mounting transesophageal recording, monitoring or stimulation devices to an esophageal stethoscope

Anatomical probe attachment

An esophageal probe for transesophageal cardiac stimulation or monitoring. The probe comprises an elongate member adapted to be positioned within the esophagus of a patient and having a distal end and a proximal end. A second elongate member is slidably mounted on the first and engages at least one electrode carrier for selectively displacing an electrode laterally relative to the elongate member for positioning the electrode at the optimal position for cardiac stimulation and monitoring of the patient.

Esophageal probe for transeophageal cardiac stimulation

An esophageal stethoscope comprises a tubular flexible body having a proximal end and a closed distal end, an acoustic region defined on the body and spaced from the closed distal end. First and second spaced apart electrodes are mounted on one side of the body and between the distal end and the acoustic input region. The electrodes are spaced from each other and the distance between the mid-point of the electrodes and the acoustic input region is about 5-10 cm. A second pair of electrodes are mounted between the distal end and the first electrode pair and are manually movable laterally into engagement with the esophageal tissue.

Esophageal probe for transesophageal cardiac stimulation

An esophageal probe comprising an elongated tubular body member with a distal portion that is insertible into an esophagus and a pair of oximeter sensors mounted in a spaced apart relation on the body for generating electrical signals functionally related to the fraction of hemoglobin in blood in the form of oxyhemoglobin.
