|
Rate Pressure Product |
Measures the workload, or oxygen demand, of the heart, and reflects hemodynamic stress |
|
|
Difference Between Restrictive and Obstructive Lung Pathologies |
restrictive: the compliance of the lung is reduced. Common causes: pulmonary fibrosis, pneumonia and pulmonary edema.
obstructive: airway obstruction causes an increase in resistance. Common obstructive diseases include asthma, bronchitis, and emphysema. |
