Abstract: Methods and apparatus for delivering therapeutic hypothermia to a patient are provided which may include any number of features. One feature is a hypothermia system comprising a fluid source, a heat exchanger assembly, a catheter in fluid communication with the fluid source, and a pump system configured to infuse hypothermic fluid into a patient cavity and extract hypothermic fluid from the patient cavity. The hypothermia system can infuse and extract fluid automatically from the patient cavity. In one embodiment, the patient cavity is a peritoneal cavity. A safe access device to gain access to the patient cavity is also provided.

Abstract: Methods and apparatus for monitoring core temperature of a patient receiving intraperitoneal hypothermia or hyperthermia are provided which may include any number of features. One feature is placing a monitoring device having a sensor into a non-intraperitoneal cavity of a patient. The non-intraperitoneal cavity can be a urethra, a rectum, an anal sphincter, a stomach, an esophagus, the peripheral vasculature, or a vagina, for example. Another feature is sensing core temperature of the patient with the sensor.

Abstract: A non-invasive method for the early detection and assessment of the severity of various pathological conditions in pregnancy including pregnancy-induced hypertension, preeclampsia, premature uterine contractions and intrauterine growth retardation. The carbon monoxide or end-tidal carbon monoxide concentration is measured in a pregnant woman's breath and compared to thresholds for determining the likelihood of onset or actual onset of these pathological conditions. The measurements can be made in a clinic, hospital, physician's office, or any other location easily accessible to pregnant women using any of a number of devices for measuring breath carbon monoxide. One solution is to measure end-tidal breath carbon monoxide using the Natus® CO-Stat® End Tidal Breath Analyzer, manufactured and sold by Natus Medical Inc. of San Carlos, Calif.
