Respiration rate describes how often you inhale and exhale in a minute. It is also a primary vital sign along with heart rate, blood pressure, and body temperature. Resting respiration rates are typically between 12-20 times per minute during rest and can be around 40-50 times per minute during intense physical activity. This increase in respiration rate reflects the increased oxygen demand for producing aerobic energy.
Aidlab uses a transthoracic impedance measurement method to determine the respiratory rate. During respiration, the electrical properties of the chest tissues change, so by measuring the changes in thoracic impedance, the respiratory rhythm can be determined.
