Reduced compliance and pulsatility in severe PH support further validation of noninvasive plethysmography; should not yet change practice.
Can N2O body plethysmography be used to estimate pulmonary arterial compliance and capillary flow pulsatility in patients with pulmonary hypertension?
N2O body plethysmography provides a reliable noninvasive method to assess pulmonary arterial compliance and capillary flow pulsatility, which are markedly reduced in severe pulmonary hypertension.
