有控制式緊急游泳上升(CESA)是開放水域潛水員 課程中最複雜的技巧。這也是應該學習的重要緊急 程序。成功完成平靜水域的技巧後就應用在開放水 域,能使新手潛水員產生信心面對不太可能發生的 狀況時,像是沒有備用或多餘的氣源時遇到緊急狀 況,他知道還有別的選擇。

規劃技巧使學員達到在開放水域中後勤準備的 要求。這裡澄清幾個重點,幫助你順利設定好這個 技巧。

在 PADI 教練手冊 中開放水域潛水員課程教練 指引提到:


使用繫在水面浮具上的垂直控制繩。確認繩 子牢牢綁在水底,或是以足夠的重量固定在 水底,讓你隨時能單手握住或單腳纏住繩子、 另一手抓住潛水學員來停止上升。一次指導一 名學員進行這項技巧,在這項技巧中,你會同 時與學員和控制繩維持身體接觸。

使用牢固的垂直繩索的目的是提供你儘可能更好的 控制上升速率、減壓停留或減緩上升,並監督學員 的呼氣,看看是否有壓力過大的跡象。為了能夠更 好的控制,你必須同時抓住學員和繩索。或是用手 握住繩子,或是用單腳纏住的方式保持與繩子的 接觸。 50 kata lagi
