Reduces risk of death from agitated delirium

Question 4

Answer 4

Benzos

Question 5

Poiseuille’s law

Answer 5

Principal that volume of a fluid is directly proportional to pressure differences between its ends and to the fourth power of its internal radius
Inversely proportional to its length

Question 6

Flow increases with

Answer 6

Decreased length
Increased pressure differential
Increased radius (4th power)

Question 7

IO medication exceptions

Answer 7

Chemotherapeutic agents
TPN
Long term infusion of hypertonic agents

Question 8

IO flow rate

Answer 8

1. Proximal humerus: 5L/hr, central circulations within 2 seconds
2. Proximal tibia: 1L/hr, femoral circulation within 22 seconds
3. Sternum: 125 cc/min under pressure, heart within 2 seconds

Question 9

Lidocaine dose for analgesia in IO

Answer 9

2% cardiac dose pi
20-40 mg follow by 10 cc flush
For Peds: 0.5 mg/kg

Question 10

Most reliable assessment of pain

Answer 10

Self reporting scales

Question 11

Boyles law

Answer 11

Gas pressure and volume are inversely proportional

Question 12

Boyles law considerations

Answer 12

Barotrauma
PTX
Balloon in ET tube

Question 13

Daltons law

Answer 13

Total barometric pressure = sum of partial pressures (partial pressure is total pressure x % gas)

Question 14

Effect on O2 with ascent

Answer 14

As you ascend, percentage of oxygen remains constant, but partial pressure decreases
Leads to decreasing O2 availability

Question 15

Henrys Law

Answer 15

Amount of gas dissolved in a liquid is a function of applied pressure

Question 16

What law is associated with decompression sickness

Answer 16

Henrys law

Question 17

Grahams law

Answer 17

Gases diffuse from higher to lower concentration
lower density gases diffuse better

Question 18

Gay-Lussac’s law

Answer 18

Pressure and temperature are directly related when volume of gas is constant
(pressures in O2 tank decrease as temp increases)

Question 19

Who is affected in isolation syndrome

Answer 19

Family members for those with chronic diseases
