Coranary artery bypass graft. Unspecified complication of cardiac and vascular prosthetic device, implant and graft
Conditions
Interventions
Intervention 1: A blood pressure cuff on the upper arm and the second cuff on the thigh will be applied. In Group I, upper arm tourniquet cuff will be inflated rapidly to 100 mmHg over the initial sy
Prevention
A blood pressure cuff on the upper arm and the second cuff on the thigh will be applied. In Group I, upper arm tourniquet cuff will be inflated rapidly to 100 mmHg over the initial systolic blood pre
In group II when the upper limb cuff is deflated the lower limb cuff will be inflated and vice versa.
In the third group, or control group, none of the cuffs will be inflated.
