Description
この方法は、目標CPR圧迫深さに関する情報を使用者に提供することを含み得る。
使用者に対する使用者により実施される胸部圧迫に関する周期的フィードバックは、使用者に対する圧迫深さに関するフィードバックを含み得る。
この方法はまた、患者の心活動に関する情報を受け取ること、及び画像ディスプレイに、胸部圧迫に関するフィードバックと共に、患者の心電図を表示することも含み得る。
使用者に対する胸部圧迫に関する周期的フィードバックは、複数の胸部圧迫の深さを表示する棒グラフと、目標圧迫深さのインジケータとを含み得る。
複数の胸部圧迫の深さに関する情報を取得することは、患者の胸骨と連動するように位置決めされた加速度計から、患者に対して実施される胸部圧迫に関するデータを取得することを含み得る。
携帯型演算装置は、タッチスクリーンタブレットコンピュータであってもよい。
この方法はまた、個人の生理学的パラメータに関する情報のグラフィック表現を表示することも含み得る。
この方法はまた、生理学的パラメータの値のトレンドに関連するトレンドデータを含む生理学的パラメータに関する情報のグラフィック表現を表示することも含み得る。
決定されたトレンドのグラフィック表現を表示することは、潜在的なトレンド方向を示す複数の矢印を提供すること、及び複数の矢印のうち1つに関連する視覚的指示であって、決定されたトレンドの方向を示す視覚的指示を提供することを含み得る。
第1の頻度は5秒以下の頻度であってよく、第2の頻度は10秒以上の頻度であってよい。
ボックス514に表示される胸部圧迫に関する情報はまた、灌流機能インジケータ(PPI)520も含む。PPI520は形(例えば、菱形)であり、その形の塗りつぶし量が異なることにより、圧迫の頻度及び深さの双方に関するフィードバックが提供される。CPRが適切に実施されている、例えば約100回圧迫/分(CPM)の頻度により、各圧迫が3.81cm(1.5インチ)より深い深さで実施されているときは、インジケータ全体が塗りつぶされる。頻度及び/又は深さが許容限度未満に低下すると、塗りつぶし量が減る。PPI520は、救護者がPPI520を完全に塗りつぶされた状態に保つことを目標とすることができるように、CPRの質の視覚的指示を提供する。
CPR深さ計920上に表示される深さバー928は、救護者によって施行された直近のCPR圧迫の圧迫深さを表し得る。例えば、CPR深さ計920は、直近10〜20回のCPR圧迫(例えば、直近10回のCPR圧迫、直近15回の圧迫、直近20回のCPR圧迫)の深さバー928を表示することができる。別の例において、CPR深さ計920は、特定の時間間隔(例えば、直前の10秒間、直前の20秒間)において施行されたCPR圧迫の深さバー928を表示することができる。
