Spirometry
Spirometry measures the breathing capacity of the lungs using an instrument that measures expired lung volumes and flow-volume curves.
Bedside Airway Evaluation | TIME to FILL Is More Important Than Noise Level
At the bedside of a patient with suspected upper airway obstruction, inspiratory noise can be striking—but misleading. A more reliable indicator is the TIME required to fill the lungs using Dr. Bastian’s “empty-to-full” breathing test.
Here, Robert Bastian explains the concept and demonstrates it with a patient example.
