anesthetic equipment Flashcards
how are oxygen tanks attached
by a yoke
what does the pin index system do
ensures propor gas tank was attached to the machine
what does the 02 pressure gauge do
indicates how much 02 is in cylinder
psi of 02 entering the flow meter
40-50 psi
what does the flow meter do
reduces pressure further to 15 psi
where is the ball indicator read
center
what is 02 rate read in
L/min
what does the oxygen flush valve do
allows 02 to flow into the breathing circuit without going through the vaporizer
what can happen if too much pressure enters the lungs
emphysema
where is the precision vaporizer used
out of the circle
what are two positives to rebreathing circuits
keeps patient warm, low flow rates
can the machine be operated with broken flutter valve
no; must use a rebreather
PPV
positive pressure ventilation
how often should the pt. be “bagged”
every 5 minutes
what pressure reading is too high in lungs
50cm/H20
