Table 2 Part of process models for stroke diagnosis and treatment

1

CT and blood glucose should be tested before IV thrombolysis

 < precedence, CT examination, thrombolysis, > and < precedence, blood glucose test, thrombolysis, > 

2

The door-to-needle time (DNT) should be within 60 min

 < precedence, admit, thrombolysis, ψ(1,1) > 

ψ(1,1) = [complete time, complete time,60, <]

3

BP need to be kept less than 180/100 mm Hg

 < precedence, vital_signs test, antipyretic, ψ(3,) > 

ψ(3,) = [systolic pressure, 180, <]&[diastolic pressure, 100, <]

4

For patients who have received a treatment dose of low-molecular-weight heparin within 24 the previous hours, IV alteplase should not be carried out

 < Not coexistence, heparin injection, thrombolysis, > or < precedence, heparin injection, thrombolysis, ψ(1,1)> 

ψ(1,1) = [complete time, start time, 24*60, >]

5

For dispensing drugs, at least two nurses should execute a double check

 <existence, dispensing drugs, ψ(6,6)> 

ψ(6,6) = [executor, proofreader, ! =]
