開放式呼吸計(open-flow respirometry)是測量生物能量代謝比較常用的方法，受到世界各國動物生理生態學、生物醫學等領域科學家的長久青睞。
北京易科泰生態技術有限公司代理的美國Sable Systems International品牌是世界上專業的動物能量代謝測量技術公司，其產品以高靈敏度、高分辨率等性能應用于很多特殊呼吸模式的野生動物、各種實驗動物及經濟動物等生物，如具有間歇式呼吸的昆蟲、爆發式呼吸的潛水動物、特定行為代謝的野生及實驗動物等，并有大量的研究文獻及實驗方法、案例供參考。
本案例僅有美國喬治?？怂勾髮W知名的動物能量學實驗室Powers Research Lab ~ Studies in Animal Energetics (http://www.dpowerslab.com/) 研究蜂鳥、蛇及蜥蜴為案例介紹動物能量學測量技術，包括針對不同的研究動物，選擇不同的SSI呼吸代謝監測模塊，以及特殊呼吸室的制作。
蜂鳥是世界上最小的鳥，體重甚至不足2克，能夠通過快速拍打翅膀而懸停在空中，也是是唯一可以向后飛的鳥。為維持極速飛行、上下翻飛、高速俯沖等日?；顒?，蜂鳥的能量消耗及食物利用效率是非常驚人的。
作為動物能量學研究特別是蜂鳥代謝研究的權威機構，dpowerslab實驗室選購了不同的SSI動物呼吸代謝監測系統以滿足不同動物研究的需要，如FOXBOX-C便攜式氣體分析儀，可直接帶到野外測量動物的代謝率;Field Metabolic Systems便攜式動物代謝儀，可監測動物能量代謝及水代謝;SSI模塊式動物呼吸代謝測量系統，可根據研究目的，選擇不同的差分式氧氣分析儀、高靈敏度及分辨率的溫度檢測儀等模塊，研究動物在不同行為狀態時的能量消耗。呼吸室的靈活性選擇使得SSI便攜式、模塊化代謝測量系統可以研究從單只果蠅到大型鯨魚的能量學研究。
以下為dpowerslab實驗室用于蜂鳥、蛇類及蜥蜴的SSI便攜式及模塊式動物代謝測量系統的圖片展示：
