1. In case of pulmonary embolism it is well known that ECG might not show changes of acute cor pulmonale.

2. Regarding blood gas studies - SPO2 might not be low if the embolus is very small.

3. Even when the patientís X-ray chest is normal, but the patient has a report of mis-matched ventilation perfusion scan - very often such findings are not due to pulmonary embolism.

Coming to the clinical diagnosis of pulmonary embolism ó

1. If the patient has got signs of deep vein thrombosis, specially involving the large veins.

2. If the patient is a known chronic cardiac case

3. Patient is a known case of any chronic lung or any other illness or is a post-operative patient-
If such a patient complains of acute pleural type of chest pain (one side of the chest)/or develop tachypnoea and dyspnoea, there are more than 90% chances that he has pulmonary embolism. The cough with a blood stained sputum may or may not be present. The attack may present as a syncope.

In short the clinical symptoms are more important than investigations worth thousands of rupees.
