On the other hand , oscillometric method - based nibp devices with single cuff have received complaints due to doubtable systolic accuracy 普通單袖帶示波法血壓產品由于收縮壓的準確性受到質疑而在臨床上表現(xiàn)出很大的局限性。
The patented dual - cuff nibp measurement technique owned by jumbor combines oscillometric method and conventional korotkoff sounds method , yielding more accurate systolic number Fig1單袖帶血壓測量,收縮壓難以確定fig2雙袖帶血壓測量技術,收縮壓很容易確定
The following charts are typically obtained from single - cuff and dual - cuff nibp measurement . the waveforms from dual - cuff method has obvious advantage compared to that from single - cuff method fig 比較普通單袖帶示波法圖1和雙袖帶血壓測量技術取得的波形圖2 ,可以很清晰地看出后者的優(yōu)越性。
According to this technique , two cuffs are applied to the patient s arm during the period of nibp measuring . the upper cuff supplies varied pressure to the arterial vessels , meanwhile the lower cuff acts as a stethoscope to detect pulse signals 雙袖帶血壓測量技術建立在傳統(tǒng)血壓測量技術的基礎上,結合柯氏音和示波法測量的優(yōu)點,讓自動準確的測量成為可能。
