Chapter 10 Flashcards
The movement of gases from an area of high concentration to an area of low concentration
Diffusion
The diffusion of oxygen and carbon dioxide that takes place between the alveoli and circulating blood
Pulmonary respiration
The diffusion of oxygen and carbon dioxide that takes place between the cells and circulating blood
Cellular respiration
COPD
Chronic obstructive pulmonary disease
Anemia
A disease that causes low amounts of hemoglobin in the blood
The exchange of gases
Respiration
The exchange of gases between alveoli and the blood
External respiration
Gas exchange Between the blood and the cells
Internal respiration
Low levels of oxygen
Hypoxia
Chemoreceptors
Special sensor in the cardiovascular system detect increasing levels of carbon dioxide as well as low levels of oxygen
The production of breathing to the point where oxygen intake is not sufficient to support life
Respiratory failure
When breathing completely stops
Respiratory arrest
Adequate breathing
Need supplemental oxygen due to a medical or traumatic condition
Respiratory failure interventions
Assisted ventilation pocket mask bag valve mask or FROPVD
Respiratory arrest interventions
Artificial ventilation pocket mask bag valve mask FROPVD
10-12 breaths per min adult
20 breaths per min infant or child
FROPVD
Flow restricted oxygen powered ventilation device
Signs of adequate breathing
Look -Adequate an equal expansion of both sides of the chest on inhale, expose and visually inspect the chest
Listen-listen for air entering and leaving the nose mouth and chest should be present in equal on both sides free of gurgling gasping crowing beating snoring and stridor
Feel-Air moving out of the nose or mouth
Adequate breathing rates
Adult 12 to 20 per minute
Child 15 to 30 per minute
Infant 25 to 50 per minute
Rhythm-regular
Depth-adequate
Major causes of Hypoxia
A patient trapped in a fire Emphysema Overdoses on drug depressing effect on respiratory system Patient heart attack Stroke Shock
Forcing air or oxygen into the lungs when a patient has stopped breathing or has in adequate
Positive pressure ventilation artificial ventilation
Side effects of positive pressure
Decrease in cardiac output dropping blood pressure
Gastric distention
Hyperventilation
Gastric distention
Filling stomach with air through the esophagus
Side effects vomiting and restriction of movement of the diaphragm
Hyperventilation
Ventilate to quickly causes too much carbon dioxide to be blown off vasoconstriction can limit blood flow to the brain
Adequate ventilation
Rise and fall of chest
Appropriate rate 10 to 12 per minute for adults
20 per minute in children
minimum of 20 per minute in infants
