PISS (pin index safety system), ASSS, DISS (diameter index safety system), low, DISS, quick
_____ is the the indexing system for small cylinders; _______ is the system for large tanks (e.g H, K) based on thread types that joins a regulator and an H cylinder; The exit point of the regulator is a ___ connection designed for __ pressure connections; Station Outlets have a _____ connection (terminal point of a piping system) which are either ____ connect or threaded;
If the ball in a Thorpe tank rises quickly and then falls it is considered to be ____ _____
dry cracked skin around nose & lips, twisting of tubing, discomfort from tubing around ears; allows higher degree of mobility/freedom (allows the patient to continue to talk, eat and drink while receiving the therapy)
What are disadvantages of a Nasal Cannula? What are advantages?
O2 enriched gas, patient, warm, premature; temp, humidity, FiO2; servo mechanism, FiO2, entrainment, 40%

decompression sickness, air embolism, CO2 poisoning, smoke inhalation, anaerobic infections, skin grafts, and refractory osteomyleitis;
For what are patients treated via hyperbaric oxygen (7 things)?
total flow=addition of air:O2 ratio
(e.g. sum of 1 : 3.2 = 4.2) & divide by flow (L/min) given in problem
Formula for calculating total flow of air entrainment device?
100-Fi02/FiO2-21, then divide bottom # into top to get air ratio, oxygen is always 1; add the total parts of ratio (ex: 1:3.2=4.2) and multiply it by the L/min given in problem to get total flow
Oxygen to air ratio calculation?
Patients tidal volume and respiratory rate; whether breathing thru nose or mouth;
What influences FiO2 delivered to a patient using a NC?
infection from surgery; hemoptosis and subcutaneous emphysema
complications of transtrachial catheter?
6 l/m 60%, 7 l/m 70%, 8 l/m 80%, 9 l/m 80+%, 10 l/m 80+%
what is the FiO2 of PRB (partial rebreather?
PaO2=(Pb-PH20)Fi02-(PaC02*1.25), when FiO2 is >than 60%
What is the Alveoloar air equation? When do leave off the last part of the equation (*1.25) ?
intermittent postitive pressure breather (IPPB), Good fitting non rebreather mask attached to a reservoir bag, with flow high enough to prevent collapse of bag.
What type of O2 device is used to administer Heliox treatment to intebated patient? to non-intebated patient?
max flow is 6 liters and % is (.24 -.44' % -.21) / 4 liters
convert % to NC if patient is not tolerating a mask? Also go backwards with the conversion % (this will be liter flow on NC)?

Boyle's Law, P1xV1-P2xV2
the law that states: the volume that a gas occupies, when it is maintained at a constant temperature, is inversely proportional to the absolute pressure exerted upon it. What is the formula?
charles Law, V1/T1=V2/T2
the law that states: when a gas is held at a constant pressure, volume and temperature are directly proportional; What is the formula?
combined gas law, P1V1/T1=P2V2/T2
the law that explains: behavior of gases when any or all variables change simultaneously; What is the formula?
the law that states: when you decrease the radius of a tube by 1/2, the the resistance increases by 16x;
pressure that has dropped as fluid flows thru a constriction, can be restored to a preconstriction state by gradual dialation, distal to the constriction;
states that as velocity of a gas increases, the pressure on the lateral wall decreases
