This equation defines mean arterial pressure.
What is MAP = CO × SVR?
This equation is used to calculate alveolar oxygen tension.
What is the alveolar gas equation?
This IV induction agent causes dose-dependent hypotension via decreased SVR and contractility.
What is propofol?
Normal cerebral perfusion pressure is defined as the difference between these two pressures.
What is MAP - ICP?
An increase in preload primarily affects this variable on the pressure-volume loop.
What is stroke volume?
This property best predicts the speed of induction and emergence for volatile anesthetics.
What is blood–gas solubility?
Hyperventilation decreases intracranial pressure primarily by lowering this variable.
What is PaCO₂?
Positive pressure ventilation decreases venous return primarily by increasing this pressure.
What is intrathoracic pressure?
Increasing PEEP improves oxygenation primarily by increasing this lung volume.
What is functional residual capacity?
This neuromuscular blocker is contraindicated in patients with upregulated acetylcholine receptors.
What is succinylcholine?
The context-sensitive half-time of this opioid increases significantly with prolonged infusion.
What is fentanyl?
Loss of cerebral autoregulation is most likely when MAP falls below this approximate threshold.
What is 50 mmHg?
This diuretic class commonly causes metabolic alkalosis and hypokalemia.
What are loop diuretics?
In severe aortic stenosis, maintaining this variable is most critical to preserve coronary perfusion.
What is diastolic blood pressure?
This physiologic change during one-lung ventilation is the primary mechanism that limits hypoxemia.
What is hypoxic pulmonary vasoconstriction?
