Type 1 and 2 respiratory failure general cause?
Type 1 - failure of oxygenation
Type 2 - failure of respiration (pump)
What is FEV1?
Forced expiratory volume in 1 sec
Volume of air pt can expire forcibly in 1 second
What is FVC?
Forced vital capacity
The total volume of air a pt can expire in 1 breath

Method for interpreting CXR?
Name, date, type (PA or AP; erect; mobile)
RIPE
(Rotation, inspiration, penetration, exposure)
A - airway: trachea, carina, bronchii
B - breathing: lung fields, markings, vasculature
C - Cardiac: heart size, heart borders
D - Diaphragm: costophrenic angles; flattened; pneumoperitoneum
E - Everything else: BONES, apices, behind heart.
Method for interpreting AXR?
Name, date, type.
RIPE
A - air (bowel air) - air in bowel, type of bowel seen, faecal loading
B - Bones - lower ribs, vertebrae, pelvis
C - calcification - in bones/pancreas/liver/KUB
S - soft tissue - organs, liver, pancreas, stomach, kidneys
