Types of Spirometers & Technologies used
Spirometer is the instrument used to measure lung capacity and volume. The record obtained from spirometer is called a spirogram. There are a number of spirometers used in respiration volume measurements. In this article, we look at general types of spirometers according to their application and some of the technologies utilized in these spirometers. There…

Key Considerations in Respiratory Measurements & Instrumentation Involved
Airflow The airflow in the respiratory system is normally laminar. However, during heavy breathing or when there is an obstruction, the airflow may become turbulent. The airflow is laminar unless the Reynolds number of the flow becomes 50,000 or more. When the Reynolds number is small, the viscous force in the flow dominates over the…
