The objectives of our study were (1) to implement intelligent respiratory alarms with a neural network; and (2) to increase alarm specificity and decrease false-alarm rates compared with current alarms. ⋯ Neural networks may be useful in creating intelligent anesthesia alarm systems.

Rapid and accurate core temperature measurement is vitally important in trauma patients, especially in those with accidental hypothermia. We tested a new aural thermometer to measure "tympanic" temperatures and assessed its accuracy during normothermic and hypothermic cardiopulmonary bypass. ⋯ The new tympanic thermoprobe is a simple, fast, and reliable device for measuring core temperature. The device was designed particularly for, and may be useful for, patients suffering from accidental hypothermia.

Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of intraarterial with continuous noninvasive blood pressure measurement in postoperative pediatric patients.
The purpose of this study was to estimate the accuracy, bias, and frequency response of continuous blood pressure monitoring using finger photoplethysmography in children. ⋯ Substantial measurement bias exits between this noninvasive blood pressure measurement technique and intraarterial blood pressure. Measurements of the intrapatient variability and frequency response analysis suggest that the noninvasive technique accurately tracks intraarterial blood pressure over the short term. This technique may have useful applications in settings where intraarterial monitoring is undersirable or unobtainable.
