what are the 3 reason O2 is given?
decrease WOB, Tx hypoxemia, decrease myocardial work
Radiolucent
dark air pattern
radiodense
white pattern solid fluid
infiltrate
any ill defined radio density
consolidation
solid white area
hyperlucency
extra pulmonary air
vascular markings
Lymphatic vessels lung tissue ( increased markings in CHF, decreased markings with pneumothorax)
diffuse
spread throughout
opaque

honeycomb (reticulondular)
ARDS/IRDS/ILD
,air bronchogram
pneumonia/ edema
Peripheral wedge-shaped infiltrate
pulmonary embolism
concanve superior interface/ border
pleura effusion
Basilar infiltrates with meniscus
pleura effusion
bleb
air filled pocket > 1 cm
bullae
air filled pocket < 1 cm
white/gray sputum
asthma/ chronic bronchitis
bright red sputum (Hemoptysis)
fresh blood, tumor, TB
yellow sputum
increased WBC, bacterial infection
brown/ dark sputum

normal PaO2 range
80-100 mm Hg
, Mild Hypoxia range
60-80 mm Hg
moderate hypoxia range
40-60 mm Hg
severe hypoxia range
<40
calculation for total room air
100-x/x-21 (< or equal to 40% FiO2)
100-x/x-20 (> 40% FiO2)
calculation for total flow
