Prompt treatment of the chest pain patient in the emergency department (ED) is crucial. To ensure prompt treatment, identification of factors that delay flow of these patients through the department is essential. To identify factors that delay patient flow through the ED, the authors conducted a prospective study of all chest pain patients, using a time-flow analysis. ⋯ Additional findings confirmed the efficacy and role of the triage nurse in patient flow. Nursing and medical education and staffing needs were addressed. The use of the community's emergency medical services was examined by analyzing the disposition of patients arriving at the ED by ambulance.

The accident rate for emergency medical service (EMS) helicopters is thought to be approximately twice the rate for other commercial (Part 135) helicopters. This observation has led to numerous news reports and to the publication of conclusions of a National Transportation Safety Board investigation. The data for these reports come from investigations of EMS helicopter accidents and incidents. ⋯ The single most important factor identified was the number of flights made by the program during the study period: busy programs had an eightfold lower accident rate (P less than .0005) and a three-fold lower total mishap (accidents + incidents) rate (P less than .0005) than less active programs. Programs with the ability to fly under instrument flight rules (IFR) at the pilots discretion had no mishaps (P = .044) during the study period. Multivariate analysis shows this IFR capability to be marginally significant as an independent factor (P = .099).

The authors present three patients who developed a tension pneumothorax while receiving emergent hyperbaric oxygen therapy for acute carbon monoxide poisoning. Each patient was intubated and received closed chest compressions for cardiac arrest prior to hyperbaric oxygenation. ⋯ These cases illustrate the need for vigilance in detecting and addressing pneumothorax prior to hyperbaric decompression in obtunded patients. Serial physical examinations, arterial blood gas determinations, properly positioned chest radiographs, and a high index of suspicion for pneumothorax in the setting of emergent hyperbaric therapy are recommended.
