Application of impedance pneumoplethysmogram and impedance respirogram to investigate pulmonary heart disease correlation with diaphragmatic muscle fatigue / 中国组织工程研究

ABSTRACT

Objective To investigate correlation of pulmonary heart disease (PHD)with the diaphragmatic muscle fatigue(DMF). Methods Impedance Pneumoplethysmogram(IPG) and Impedance respirogram(IRG) were detected in 64 cases of patients with PHD,and investigate DMF rheogram positive rate,also analysed various parameters of IPG in positive and negative groups. Results (1)The positive rate of DMF.Rheogram in PHD with and without respiratory failure are 75％ and 21.9％ respectively.(2)The positve rate in PHD with and without heart failue are 80％ and 46.3％ respectively.(3)The mean values of various parameters of IPG in positive and negative DMF rheogram have no significant difference.Conclusion Respiratory failure and heart falure in PHD are closely correlated with DMF. However,the occurance of DMF are not parallel with the severity degree of PHD.
