<prompt> Compensatory mechanism in acute hemorrhage?Decreased myocardial contractilityDecreased hea rateIncreased hea rateIncreased respiratory rate  <response>: Ans. is c i.e., Increased hea rate Compensatory mechanisms in acute hemorrhage In acute hemorrhage there is compensatory sympathetic stimulation which causes :? 1 Generalized vasoconstriction with increased total peripheral resistance TFR. 2 Increased hea rate tachycardia. 3 Increased cardiac contractility. 4 Increased renin release causing sodium and water retention through RAA system. 5 Shift of fluid from intracellular and interstitial space into vascular space.
