FOCUS may lower PE diagnosis in ED patients with suspected PE and abnormal vitals

A study published in Academic Emergency Medicine found that Focused Cardiac Ultrasound (FOCUS) can significantly lower the likelihood of pulmonary embolism (PE) diagnosis in ED patients with suspected PE and abnormal vital signs. The results suggest that FOCUS can be an important tool in the initial evaluation of these patients.

Study: Actually, potted plants don't improve indoor air quality

Researchers from Drexel University review a decade of studies on the air-purifying effects of potted plants and find that natural ventilation is far more effective at cleaning the air than plants. To compete with building air handling systems, it would take between 10 to 1,000 plants per square meter of floor space.
