Pulmonary function with expiratory resistive loading in healthy volunteers
Fig 3
Rectangular area ratio group data and a representative participant.
Panel A Rectangular Area Ratio (RAR) measured with and without imposed expiratory loading (F[1.855, 77.90] = 3.711, p<0.05). Panel B A representative participant without any loading in which the RAR = 0.54. Panel C The same participant in which the loading of 7 cmH2O resulted in RAR = 0.49. Panel D The same participant in which the flow-volume relationship was at 11 cmH2O loading resulted in RAR = 0.45. *Different from control (p<0.05).
