To determine whether the alveolar dead space volume (V(D)alv), expressed as a percentage of the alveolar tidal volume (V(D)alv/V(T)alv), can predict the degree of vascular occlusion caused by pulmonary embolism (PE). ⋯ The V(D)alv/V(T)alv correlates with the lung perfusion defect and the pulmonary artery pressures in subjects with PE. These findings show the potential for V(D)alv/V(T)alv to quantify the embolic burden of PE.

To estimate the benefit of routine electrocardiographic (ECG) telemetry monitoring on in-hospital cardiac arrest survival. ⋯ Cardiac arrest is an uncommon event among telemetry ward patients, and monitor-signaled survivors are extremely rare. Routine telemetry offers little cardiac arrest survival benefit to most monitored patients, and a more selective policy for telemetry use might safely avoid ECG monitoring for many patients.

Comparative Study
Evaluation of protocols allowing emergency medical technicians to determine need for treatment and transport.
To determine whether emergency medical technicians (EMTs) can safely apply protocols to assign transport options and to assess agreement between groups of providers on application of the protocols. ⋯ From 3% to 11% of patients determined on scene not to need an ambulance had a critical event. Emergency medical services systems need to determine an acceptable rate of undertriage. Further study is needed to determine whether better adherence to the protocols might increase safety.

Many rural communities have difficulty maintaining a medical director for their emergency medical services (EMS). Local physicians may be overwhelmed, be hesitant to take on additional responsibilities, and feel unskilled in providing the necessary leadership. Without a medical director, rural EMS agencies are frequently forced to shut down, thus depriving the community of local out-of-hospital care. ⋯ This unique program enables local EMS agencies to continue their service while providing clear educational benefit for the EM residents. This paper demonstrates how this program has been working successfully in the state of Colorado by placing residents in four distinct rural and mountainous communities.
