Arterial waveform upstroke reflects
Contractility and SVR
Upstroke on arterial waveform will be faster if
Increased contractility or decreased SVR
Invasive BP is usually how much higher than NIBP
20 mmHg higher
What agency specified the purity of medical gases?
Who is it enforced by
Purity by US Pharmacopoeia
Enforced by FDA
Who controls filling and manufacturing of cylinders
DOT
What is the most common contaminant of medical gas lines
Water
What volume on anesthetic vapor is produced by 1 ml of volatile anesthetic liquid
About 200ml of anesthetic vapor at 20C and 1 atm
What is the temperature and pressure in desflurane vaporizer
Heater to 39C
Pressurized to 2 atm (1300mmHg)
At high altitude what happens to des partial pressure
Partial pressure will be decreased in proportion to atmospheric pressure
Must increase concentration of dial for desired partial pressure
Alpha angle on capnography is decreased with
Obstructive lung disease
Beta angle on capnography will be increased with
Rebreathing
Malfunctioning inspiratory valves
Pressure limit for mask ventilation
