Answer #1

When oxygen combines with hemoglobin in the blood it forms oxy-hemoglobin and it helps in transport of oxygen to different parts of the body where the oxygen then dissociates from the oxy-hemoglobin and enters the cells.

The oxygen-hemoglobin saturation/dissociation curve depends upon temperature, pH and Bi-phosphoglyceric acid (BPG).

When the temperature increases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and enters the cells of the tissues.

When the pH decreases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and thus enters the body cells.

When the concentration of BPG increases then more readily oxygen dissociates from hemoglobin due to which oxygen gets released from oxy-hemoglobin and oxygen enters the cells.

A pulse oxymeter determines a person’s oxygen saturation, that is what fraction of the hemoglobin in their bloodstream carries an oxygen molecule. Hemoglobin molecules that are carrying oxygen strongly absorb 940 nm waves, while hemoglobin without oxygen instead strongly absorbs 660 nm light. So, pulse oxymeters contain two light sources at 660 nm and 940 nm. Typically the device is (painlessly!) clipped onto person’s finger, and by comparing how much 660 nm and 940 nm light is transmitted through the...
