This article has reviewed some of the current airway management practices as well as technologic advances in adult tracheal tube design in the critically ill patient. Although the primary goals of airway protection and facilitation of positive pressure ventilation remain unchanged, a better understanding of the limitations of tracheal tubes, as well as strategies for optimized airway management, is critical. Such information is needed in order to reduce or avoid potential complications associated with tracheal tubes or similar airway devices.

Pulse oximetry is one of the most commonly applied technologies in acute and critical care. It has the potential to continuously monitor pulmonary function, avoid unnecessary blood gases, and alert clinicians to hypoxemic events that are not readily apparent by physical assessment. Due to these advantages, pulse oximetry has a firm place in health care. ⋯ In addition, oximetry has the potential to be misused owing to its widespread application. In order to obtain the maximum benefits from this technology, clinicians must be educated about the strengths and limitations of oximetry. If this education effectively changes clinicians' behavior, pulse oximetry will provide an excellent clinical advantage in patient assessment as well as moderate cost benefits.

Review Case ReportsCapnography. A key underutilized technology.
Based on the multiple applications and the potential cost savings, every ICU should have enough capnography for all intubations and probably for all mechanically ventilated patients. Of the multiple clinical applications of capnography, most attention should be focused on its use with intubation and resuscitation. Other applications, such as blood gas and ventilation-perfusion scan reduction, should be instituted after the primary areas have been implemented. While capnography modules may appear to be expensive at first glance, an analysis of their clinical application reveals they can save the hospital hundreds of thousands of dollars beyond the purchase price.

ReviewAdvances in continuous, noninvasive hemodynamic surveillance. Impedance cardiography.
In the current climate of shrinking health care reimbursement and increasing importance of patient centered care, impedance cardiography is one method of enhancing quality of patient care and appropriate use of resources. Hemodynamic and thoracic fluid status data may be obtained quickly, accurately, and without risk, providing a global clinical perspective. ⋯ Application of a technology assessment model to impedance cardiography illustrates the utility of this method of hemodynamic monitoring. Careful review and critique of the literature differentiates the available impedance technologies, supports use in areas not traditionally associated with hemodynamic monitoring, such as the home and emergency department, and validates the use of impedance cardiography in place of, or as an indication for, pulmonary artery catheterization.

With the expansion of higher acuity patients in noncritical care areas, the perceived need for arrhythmia monitoring has also escalated. For institutions pursuing this expansion, many factors must be kept in mind, including patient criteria for telemetry initiation and discontinuation, staff competency of ECG interpretation, safety, technology required, usability, and cost effectiveness. All of these issues must be addressed according to the individual institution's needs and the needs of the patient populations they serve.
