ReviewReview article: Non-invasive assessment of cardiac output with portable continuous-wave Doppler ultrasound.
Cardiac output is considered an important parameter when assessing the cardiovascular status of a critically ill patient. Both non-invasive (e.g. bioimpedance, echocardiography) and invasive methods (Swan Ganz catheter) have been used to measure cardiac output. ⋯ In this short review article, we will introduce this new technique, discuss the required skills and compare it with methods already in use. In particular, a critical comparison with the 'gold standard', the invasive measurement of cardiac output with the pulmonary artery catheter, will be given.

Comparative StudyStreaming by case complexity: evaluation of a model for emergency department Fast Track.
To evaluate a patient flow streaming system within a teaching hospital's ED, using functional principles to separate patients into two streams on the basis of complexity rather than acuity, severity or disposition. ⋯ Key features in the success of the system included use of dedicated senior staff for Fast Track patients, and quarantining of clinical resources. The ED aiming to improve their waiting times and throughput should consider using complexity as a key criterion for triaging patients into separate streams. A low-complexity patient stream in the ED provides an ideal focus for advanced nursing practice.

Comparative StudyVariables that predict admission to hospital from an emergency department observation unit.
To determine factors predictive for patients requiring ongoing hospital admission from the emergency department observation unit (EDOU). ⋯ Variables exist that predict a 'failed' short stay admission. These might be used to identify patients less suitable for admission to the EDOU and better suited to admission directly under a hospital team.
