solid- fat, tutor cells, atheromatous material, forming matter
liquid: amniotic fluid
gas: nitrogen bubbles, air
4

PE symptoms
A
if high clinical suspicion - pleuritic chest pain
- risk factors e.g. prolonged immobility, active/current cancer, previous VTE, sinus tachycardia
5
Q
PE management
A
if high clinical suspicion treat with DOAC e.g. rivaroxaban or apixaban or LMWH
this can be given before confirmation on CTPA
