Miscellaneous
The name of the sac surrounding the heart
What is the pericardium?
Where the right ventricle pumps blood in a normal heart
What is the pulmonary trunk?
Operates through CNS signals to manage vascular tone
What is central or extrinsic control?
What is represented by "PAO"?
What is the airway opening pressure?
fB X VT
What is minute ventilation?
What is the volume of gas measured during inspiration?
What is the tidal volume?
This brings deoxygenated blood from the heart to the lungs for gas exchange
What is the pulmonary artery?
Independently alters perfusion during normal conditions to meet the metabolic needs of the body
What is pleural pressure?
(PaCO2 - PECO2) / PaCO2
What is the modified Bohr equation or physiologic dead space?
A property or characteristic that alveoli overcome to inflate
What is surface tension?
Where systemic circulation ends
What is the vena cavas?
Where most of the central controls stem from
What is the medulla?
A increase in this for head injury patients is highly concerning
What is intracranial pressure?
The sum of all frictional forces opposing blood flow in systemic circulation
What is systemic vascular resistance?
What is defined as the "systolic force response"?
Contractility
Poor compliance makes the plateau pressure values...
What is increase?
Selected peripheral receptors work with the higher brainstem to manage metabolic demands under these conditions
What is exercise, pain, and significant bleeding?
A valuable measurement of the pressure in the arteries carrying blood from the heart to the lungs
What is pulmonary artery pressure?
HR X SV
What is cardiac output?
What is static?
Fibrosis makes the transpulmonary pressure required to achieve VT...
What is increase?
Local chemical changes in the blood and cerebral spinal fluid may alter these centers of control
What is medullary?
change in transalveolar pressure / change in flow
What is airway resistance?
