Ch 9 Flashcards
Minute volume
The amount of air moved into and out of the lungs per minute
MV=TV•RR
Ventilations
The process of breathing in and out or artificial provisions of breaths
Dead air space
The remaining air that occupies the trachea, bronchioles, and other parts of the airway
Acrobat ventilation
The amount of air that reaches the alveoli
Diffusion
Movement of gases from high to low concentration area
Pulmonary respiration
Diffusion of oxygen and carbon dioxide that takes place between the alveoli and the circulationg blood
Cellular respirations
The diffusion of oxygen and carbon dioxide that takes place between the cells and circulating blood
Mechanical failures in the cardiopulmonary system
Mechanics of breathing disrupted, gas exchange interrupted, circulation issues
Respiration
Exchange of gases between the alveoli and the blood and between the blood and cells
Hypoxia
Low levels of oxygen
Major causes of hypoxia
Patient is trapped in a fire
Patient has emphysema
Pt. OD’s on drug that has a depressing effect on the respiratory system
Patient has a heart attack
Respiratory distress
Increased work of breathing; sensation of SOB
Respiratory failure
Reduction of breathe to the point where hypoxia gets to the extent where it cannot support life
Respiratory arrest
When breathing completely stops
Assess breathing
Look listen feel
