(For more, see the What is being tested? section.) A hemoglobin test may be used to: Screen for, diagnose, and measure the severity of anemia (low RBCs, hemoglobin and hematocrit) or polycythemia (high RBCs, hemoglobin and hematocrit) Monitor the response to treatment of anemia or polycythemia.
Calcium channel blockers prevent calcium from entering into the heart muscle cells, and into the smooth muscle cells that cause blood vessels to constrict. This relaxing effect results in the dilation of blood vessels, and a reduced force of contraction of the heart muscle.
Serious calcium channel blocker (CCB) overdoses are nasty cases to manage often requiring a number. of prolonged and aggressive critical care interventions. It is not uncommon for small hospitals to run. out of calcium as well as vasopressor and intotropic drugs during the course of managing a CCB. poisoned patient.
