Respiratory

14 linked conditions

•Pattern of cough, dyspnea, and pleuritic pain
•Oxygen saturation and respiratory rate
•Auscultation findings and imaging pattern

How Doctors Distinguish Likely Causes

→Character of pain and exertional trigger
→Hemodynamic instability, pulse pattern, and blood pressure
→ECG and cardiac biomarkers trend
→Pattern of cough, dyspnea, and pleuritic pain
→Oxygen saturation and respiratory rate
→Auscultation findings and imaging pattern
→Pain location and relation to meals
→Stool pattern (watery, bloody, greasy) and vomiting profile
→Associated systemic signs such as fever or jaundice
→Temporal relationship with psychosocial stressors

What Changes the Differential

Age modifiers

•Age changes baseline risk: pediatric, adult, and older patients have different top causes.

Severity and acuity

•Severe or sudden-onset presentation immediately increases urgency and narrows toward dangerous causes.
•Red-flag triage first: rule out urgent causes such as Hypertensive Emergency and Pulmonary Embolism.

Timing and pattern

•Pattern "after Exercise" changes pre-test probability and guides targeted testing.
•Pattern "— Sudden Onset" changes pre-test probability and guides targeted testing.
•Pattern "at Night" changes pre-test probability and guides targeted testing.
•Pattern "with Fever" changes pre-test probability and guides targeted testing.

Associated symptoms

•Associated symptom clusters (e.g., Chest pain + Shortness Of Breath, Chest pain + Fatigue, Chest pain + Palpitations) materially alter the differential.

When Testing Is Needed

Immediate testing when red flags are present

•Vital signs and focused triage examination
•Pulse oximetry and ECG
•Basic blood panel (CBC, CRP, electrolytes, glucose)
•Immediate imaging based on dominant red flags

Group-directed workup

•ECG
•Troponin
•Blood pressure in both arms
•Echocardiography when indicated
•Pulse oximetry
•Chest X-ray
•CRP / CBC
•Spirometry in stable setting
