实验动物肺功能检测系统(PFT系统)


与人类肺功能检测原理类似,PFT可对麻醉动物进行一系列成组实验,自动检测并实时数据分析,获得相应肺功能生理参数。FRC检测要求动物保持自主呼吸状态,其它测试均可在使用呼吸机辅助呼吸或动物自主呼吸状态下进行。

主要测试:

  • 气道阻力和动态肺顺应性(RC测试)。

  • 波义耳定律(Boyle’s Law)功能残气量(FRC测试)。

  • 准静态肺部容积与肺部压力关系曲线(Pressure-Volume测试)。

  • 呼吸流速与肺部容积关系(FLow-Volume测试)。

主要参数:FRC功能残气量、FEVx第X秒用力呼气流量、FVC用力肺活量、Cchord准静态肺顺应性、气道阻力RI和动态肺顺应性Cdyn、TLC肺容积、VC肺活量等。

适用动物种属:小鼠、大鼠、豚鼠、兔、犬、猴或其它大动物模型
