Question

DO FOR 21 th dissociation curve and label and number the ne. Be sure to Please use a ruler toplot points in the correct places the c he to 30 40 0 1 0 0 20 Po What would happen to your patient's %02 sat if he has it condition that would cause arterial pO2 to decrease from 100 mm Hg to 90 mm He? 11. What would happen to O2 sat if po2 dropped to 40 mm Hg? 12 What do the two previous questions and the O2-hemoglobin dissociation curve suggest to you about the re- lationship between a patient's 02 content and O2 saturation of hemoglobin? Explain the TWO different parts of this graph

Answer 1

1) Patient %oxygen saturation will decrease when partial pressure of oxygen is decreased from 100 mmhg to 90 mm Hg. This will happen more probably the patient suffers from hypoxia. Type of hypoxia is histotoxic hypoxia. Oxygen carrying capacity of blood will decrease.

2) Percentage saturation would decrease further when partial pressure of oxygen reduced to 100 mm Hg. Most probably condition are - stagnant hypoxia. Condition in which blood flow to tissue is so low that adequate oxygen is not delivered.

3) from the previous two questions it confirm that when there is decrease in partial pressure of oxygen then percentage saturation of oxygen or Hb will decrease.

percent saturation of Hb or oxygen decreased, main reason is hypoxia. There are many types of hypoxia like hypoxic, anaemic, stagnant, histotoxic hypoxia. Here basically are histotoxic and stagnant hypoxia. In both condition the oxygen carrying capacity of blood decreased.
