Front 1

How does the cardiopulmonary system compensate for hypoxemia?

Back 1

1)By increasing ventilation
2)By increasing cardiac output

Front 2

Respiratory signs of hypoxemia

Back 2

1)mild-tachypnea, dyspnea, paleness
2)severe-cyanosis, coma, clubbing

Front 3

Cardiovascular symptoms of hypoxemia

Back 3

1)Mild-tachycardia, mild hypertension, peripheral vasoconstriction
2)severe--hypertension and eventual hypotension

Front 4

Neurologic

Back 4

1)mild-restlessness, disorientation, headaches, lassitude
2)somnolence,confusion,distressed appearance, blurred/tunnel vision, loss of coordination, slow reaction time, manic-depressive activity

Front 5

Oxygen toxicity symptoms

Back 5

1)damage to capillary endothelium
2)damage to type one alveolar cells, exudative phase
3) Pulmonary fibrosis and hypertension

Front 6

FiO2 greater than 0.5

Back 6

Causes risk of absorption atalectasis

Front 7

Nasal cannula

Back 7

1) 2-8 L
2) FiO2 22-45 %

Front 8

Simple Mask

Back 8

1) 5-12 L/M
2) 35-50%

Front 9

Partial Rebreather

Back 9

1) 6-10 L/M
2)35-60%

Front 10

Nonrebreather

Back 10

1) 6-10 L/M
2)55%-70%

Front 11

Venti mask

Back 11

1) should be greater than 60 L/M
2)Fi02 24-50%

Front 12

Factors that INCREASE FiO2 in low flow systems

Back 12

1) Higher O2 input
2)closed mouth breathing on cannula
3)low inspiratory flow
4)low tidal volume
5)slow RR
6)small minute volume
7)Long inspiratory time
8) High I:E ratio

Front 13

Factors that DECREASE Fi02 in low flow systems

Back 13

1) Low O2
2)Open mouth breathing
3)High inspiratory flow
4)High tidal volume
5)Fast RR
6)Large minute ventilation
7)Short inspiratory time
8) Low I:E ratio

Front 14

Three types of resovoir masks

Back 14

1)simple mask
2) partial rebreather
3) non rebreather
