Oxygenation Flashcards
Airway, Respiration ventilation
Hemoglobin can carry_O2 molecules
4
The process of loading oxygen molecules onto hemoglobin molecules in the blood stream
Oxygenation
A noninvasive device that measures the amount of oxygen that is bound to hemoglobin in the blood
Pulse Oximetry
The process of cells converting glucose into energy with the presence of oxygen
Aerobic metabolism
bluish or purple coloration of the skin or mucous membranes.
cyanosis
When does cyanosis occur
When the blood in the body does not carry enough oxygen, lack of oxygen can be due to obstruction, lung disease, or hypoventilation apnea
normal breathing rate in adults
12-20
Active process. Muscles in the chest expand at the same time the diaphragm contracts in a downward motion. This increases the size of the chest cavity and creates negative pressure. This pulls air through the glottic opening and inflates the lungs.
Inhalation
A sign of chronic hypoxia in older and younger people
Digital clubbing
What are three causes of incorrect reading on the pulse oximeter
Nail Polish cold extremities, Carbon monoxide poisoning
How does oxygen enter the blood stream
Within the alveoli oxygen rich air inhaled through the lungs meets capillaries while oxygen molecules are able to attach red blood cells and travel back to the heart.
What does pulse oximeter measure?
Hemoglobin in arterial blood.
Normal breathing rate in children.
15-30 BPM
What drive is responsible for breathing control? What is the backup system?
The carbon dioxide drive- increased CO2 levels to stimulate the body to increase the respiratory rate.
As a backup, the hypoxic drive will stimulate breathing when low O2 levels are sensed.
Normal breathing rate in infants
25-50 BPM
