用导管测血压有两种类型,一是导管式血压计(换能器在体外),另一是导管前端型血压计(换能器植入体内)。前后受导管共振等影响波形失真较大,后者由于换能器接触
There are two types of catheter blood pressure measurement, one catheter-type sphygmomanometer (transducer in vitro), and the other is a catheter tip-type sphygmomanometer (transducer implanted in the body). Before and after the catheter resonance caused by larger waveform distortion, the latter due to transducer contact
