Nitroglycerin-induced decrease of carbon monoxide diffusion capacity in acute myocardial infarction reversed by elevating legs

Passive leg raising predicts fluid responsiveness in the critically ill*

“…PLR induces a translocation of venous blood from the legs to the intrathoracic compartment (3,4), resulting in a transient increase in right ventricular (5) and left ventricular (6,7) preload. PLR as a "reversiblevolume challenge" (8) is attractive because it is easy to perform at the bedside, induces a reversible volume challenge that is proportional to body size, and does not result in volume overload in nonpreload-responsive subjects.…”

The Efficiency Of Preventing Hypotension By Passive Leg Raise Application In Pregnant Women Planned For Cesarean Section Under Spinal Anesthesia

“…Gebelerin 15°lik PBK öncesi ve sonrası sol lateral pozisyonda strok volümlerini ve kan basınçlarını ölçmüşlerdir. Sağlıklı gebelerde uygulanan 15° PBK manevrasının strok volümde, kalp hızında ve kalp debisinde değişikliğe yol açmadığını bulmuşlardır (48) .…”

Bilateral passive leg raising attenuates and delays tourniquet deflation-induced hypotension and tachycardia under spinal anaesthesia

“…13 PLR has also been shown to increase both the right and left ventricular preload, leading to an increase in stroke volume and cardiac output. [14][15][16] Second, PLR can increase systemic vascular resistance, 17,18 which may attenuate the tourniquet's deflation-related reduction in systemic vascular resistance. 8 Third, when the tourniquet is deflated while the legs are elevated, the normally abrupt shift in flow back to the raised legs will be slower, as gravity counteracts the blood flow.…”
