A monotone iterative technique with lower and upper solutions is presented to identify the regions of existence for the solutions of singular two-point Blood Pressure Kits boundary value problems without requiring the monotonicity conditions on f(x,y).Under an additional condition on f(x,y), uniqueness of the solution is also established.These exis
