1️⃣ Lungs do not actively expand
• Lungs have no muscles of their own.
• They are like soft balloons.
• They expand only because the chest cavity expands.
• So lungs follow the movement of the chest — they don’t work by themselves.

⸻

2️⃣ Diaphragm contraction pulls air into lungs
• The diaphragm is the main breathing muscle.
• When it contracts, it moves downward.
• This increases chest space and creates negative pressure.
• Air automatically flows into the lungs (like suction).

👉 Relaxed diaphragm = breathing out
👉 Contracted diaphragm = breathing in

⸻

3️⃣ Pulmonary embolism can mimic anxiety
• Pulmonary embolism (PE) = blood clot in lung vessels.
• Symptoms may include:
• Sudden breathlessness
• Chest tightness
• Fast heartbeat
• Sweating
• Feeling of panic
• These symptoms look like anxiety, so PE is often missed.

⚠️ Treating it as “just anxiety” can be dangerous.

⸻

4️⃣ Sudden dyspnea is always an emergency
• Dyspnea = difficulty in breathing
• If breathlessness comes suddenly, it may indicate:
• Pulmonary embolism
• Pneumothorax
• Acute asthma
• Heart failure
• Sudden breathing trouble means oxygen delivery is at risk.

🚑 Immediate medical evaluation is mandatory

⸻

5️⃣ Oxygen saturation may be normal in early PE
• In early PE:
• Some lung areas still exchange oxygen normally
• Pulse oximeter may show normal SpO₂
• This gives false reassurance.
• Patient may still have a life-threatening clot.

📌 Normal SpO₂ ≠ PE ruled out

⸻

6️⃣ Breathlessness should never be ignored
• Breathlessness is a warning symptom, not a disease.
• It can signal problems in:
• Lungs
• Heart
• Blood
• Brain
• Early evaluation can save life and lung function.
