title: New noninvasive technologies in emergency medicine.
abstract: Noninvasive technology offers many present and future benefits for emergency patients, including the painless, instantaneous and real-time tracking of oxygenation, ventilation and perfusion, as well as the quick and reliable detection of esophageal intubation. Other noninvasive technologies, such as echocardiography, are also being increasingly studied in the Emergency Department. In the future a host of new and innovative concepts, such as transthoracic bioimpedance, pulsed Doppler flowmetry, and laser Doppler velocrimetry may permit continuous and accurate noninvasive cardiac output.
