Ambient air Ventilation Cardiac output Oxygen transport
100
What is oxygen
This gas comprises 21% of ambient air at sea level
100
What is the brainstem
This is where the stimulus for spontaneous ventilations originates
100
What is cardiac output
The amount of blood ejected from the left ventricle in 1 minute
100
What is hemoglobin
This molecule is the way oxygen is primarily transported
200
What is nitrogen
This gas comprises 78% of ambient air at sea level
200
What is Boyles law
A gas law that states the pressure of a gas and its volume are inversely proportional
200
What is Stroke volume
The amount of blood ejected with each contraction
200
What is blood plasma
This is the way carbon dioxide is transported through the body
300
What is hypoxia
A patient in a low oxygen environment is in danger of suffering from this type of -oxia
300
What is inspiration
The active phase of ventilation in which the diaphragm contracts and the external intercostal muscles
300
What is preload
The pressure or "load" in the left ventricle at the end of diastole
300
What is the alveoli
where is AMBIENT air oxygen exchanged with blood
400
What is increasing the concentration of oxygen
doing this is a way to improve cellular oxygenation
400
What is hypoxic drive
This the main ventilation stimulus for COPD patients, and other patients who are less sensitive to changes in CO2
400
What is afterload
The resistance in the aorta that must be overcome by the left ventricle to eject blood into the body
400
What is the capillaries
Oxygen in the blood stream is exchanged in these structures for aerobic metabolism
500
What is 0.03%
This is the percentage of carbon dioxide in the ambient air at sea level
500
What is accessory muscles
The usage of these muscles, which are not normally used in ventilation is usually sign of respiratory distress
500
What is Hydrostatic pressure
The force or pressure exerted on a vessel or capillary bed by the contraction of the heart
500
What is respiration/metabolism
the chemical cellular process for creating ATP
