194ml/min
What is the Hamburger effect?
Red cells get bigger in the tissues
What is hematocrit
Percent of packed red blood cell volume in whole blood
For any patient, which hematocrit is higher - arterial or venous?
Venous
How big is a red blood cell
8 microns
What class of NMBs are reversed by sugammadex?
Aminosteroids
Dose of sugammadex if patient has TOF 2/4
2mg/kg
Dose of sugammadex if patient has TOF 0/4
4mg/kg

DEA schedule for Versed
Schedule IV
DEA schedule for fentanyl

DEA schedule for ketamine
Schedule III
If pus is accumulated in the chest cavity, what is the name of the material being drained?
Empyema
How does 100% FiO2 affect the distention of the airways?
100% O2 can cause atelectasis, adding air into fresh gas flows adds nitrogen to the lungs which helps distend the alveoli
Definition of emphysema
A subset of COPD in which the alveolar walls break down and become enlarged, causing less O2 to diffuse into the blood and SOB/difficulty breathing
Definition of chronic bronchitis
A subset of COPD in which over-exposure to irritants in the airway causes inflammation and increase in mucus production, creating a decrease in airflow

Patient’s height
Most numerous cation in the cells
K+

660 and 940nm
Most common transfusion associated infection
