Solution
Myocardial infarction leads to congestive heart failure and sudden cardiac death. Oxygen
supplimentation given to improve the blood oxigen saturation. In myocardial infarction there is
less release of oxigen from heamoglobin leads to tissue hypoxia.the inhalation of 100% oxigen at
high barometric pressure, called hyperbaric oxygen therapy.this causes increased the amount of
dissolved oxygen in plasma. Which is useful to relieve from ischemia. The osmolarity is the
number of osmoles per litre of solution. The solution that have same osmolarity as plasma are
said to be isotonic.e.g. 0.9% sodium chloride solution. We know that, when RBC are placed in
isotonic solution, they remain suspended in it, neither swell nor shrink because the osmotic
pressure of isotonic solution is equal to the osmotic pressure within the RBCs. Hence, by
injecting the istonic saline only extra cellular fluid volume Increase.the intra cellular fluid
volume and body osmolarity remains same. Since injecting fluid is isotonic it cannot cross the
membranes.
