Description
1.1システムの全体構成
この発明の一実施形態による心拍再開の可能性を判断する装置の機能ブロック図を、図1に示す。心電図取得手段2は、心臓停止状態における被験者に対する心臓マッサージ中の心電波形データを取得する。なお、被験者は心静止(asystole)状態等であるため本来の心電図は平坦であるが、心臓マッサージによるノイズを観測することができる。ここでは、このようなノイズも含めて、心電波形と呼んでいる。
図2に、この発明の一実施形態による心拍再開の可能性を判断する装置をCPU10を用いて実現した場合のハードウエア構成を示す。CPU10には、ディスプレイ12、操作部14、メモリ16、ハードディスク18、A/D変換器20が接続されている。
図3に、判断プログラム26のフローチャートを示す。CPU10は、ステップS1において、メモリ16に蓄積された心電波形データを取り込む。心電波形データは、電位の変化を所定時間ごとにサンプリングしたディジタルデータであり、模式的に示すと図4のようになる。
2.1システムの全体構成
図9に、この発明の第二の実施形態による心拍再開の可能性を判断する装置の機能ブロック図を示す。心電図取得手段2は、心臓停止状態における被験者に対する心臓マッサージ中の心電波形データを取得する。
ハードウエア構成は、第一の実施形態と同様である。ただし、ハードディスク18に記録されている判断プログラム26の処理内容が異なっている。
図10に、判断プログラム26のフローチャートを示す。CPU10は、ステップS1において、メモリ16に蓄積された心電波形データを取り込む。取り込まれたデータを模式的に示すと、図4Bのようになる。ピークの間隔が、心臓マッサージの胸部圧迫の間隔に対応している。
(1)上記実施形態では、各誘導における、バンドパスフィルタの出力の振幅の平均値に基づいて、蘇生可能性を判断している。しかし、バンドパスフィルタ出力のピーク値、波形積分値などに基づいて判断を行うようにしてもよい。
Claims (3)
- 心臓停止状態における被験者に対する心肺蘇生処置としての心臓マッサージ中に、当該被験者の心電波形データを取得する心電図取得手段と、
取得した心電波形データを受けて、P波の周波数成分のみを通過する帯域フィルタ手段と、
帯域フィルタの出力が所定値を越えているかどうかを判断し、越えている場合には心拍再開の可能性があると判断する蘇生可能性判断手段と、
蘇生可能性判断手段の判断結果を出力する出力手段と、
を備えた心拍再開の可能性を判断する装置。 - コンピュータによって心拍再開の可能性を判断する装置を実現するためのプログラムであって、コンピュータを、
心臓停止状態における被験者に対する心肺蘇生処置としての心臓マッサージ中に、当該被験者の心電波形データを取得する心電図取得手段と、
取得した心電波形データを受けて、P波の周波数成分のみを通過する帯域フィルタ手段と、
帯域フィルタの出力が所定値を越えているかどうかを判断し、越えている場合には心拍再開の可能性があると判断する蘇生可能性判断手段と、
蘇生可能性判断手段の判断結果を出力する出力手段として機能させるためのプログラム。 - 請求項1の装置または請求項2のプログラムにおいて、
前記帯域フィルタは、10Hz〜15Hzの周波数成分を通過するものであることを特徴とする装置またはプログラム。
