Diagnosis Guidelines

Question 1

CV Pump (Aerobic Capacity)

Answer 1

1. Abnormal vital sign response (flattened)
2. EF < 40%
3. BNP > normal values
4. > 2 mm ST elevation or depression
5. Angina
6. Onset of ventricular ectopy with increasing workload (> 7 PVC per minute) with hemodynamic compromise

Question 2

Deconditioning (Aerobic Capacity)

Answer 2

1. Bedrest for 24-48 hours

2. Exaggerated vital sign response to activity: greater than expected increase for the workload (HR, BP, RR, RPE)

Question 3

Gas Exchange

Answer 3

1. SPO2 < 97% (depending on age)
2. PaO2: abnormal for age at rest or in response to activity
3. PaCO2: abnormal at rest or in response to activity

Question 4

Ventilatory Pump

Answer 4

1. PFTs: Obstructive or restrictive
2. Significantly decreased MIP/MEP
3. Accessory muscle use at rest
4. Abnormal/uncoordinated or paradoxical breathing pattern at rest or in response to position change or activity
5. Increased AP diameter, 1:1 ratio, flat sub-costal angle on exam or chest film

Question 5

Airway Clearance

Answer 5

1. Abnormal/adventitious breath sounds or voice sounds indicative of secretions
2. Ineffective cough or effective cough not able to clear volume of secretions present
3. Chest film with evidence of infiltrate of consolidation
4. Mediate percussion note that confirms presence of retained secretions/consolidation
5. Pathology with chronic retained secretions: CF, chronic bronchitis, bronchiectasis

Question 6

Peripheral Ischemia

Answer 6

1. Claudication with ambulation

2. ABI < 0.5
