Overview

Pulmonary embolism (PE) is associated with the presence of tachycardia and tachypnea. Signs of right ventricular failure include jugular venous distension, a right sided S3, and a parasternal lift. These signs are often present in cases of massive and submassive pulmonary emboli, also known as intermediate-risk and high-risk respectively.^[1]^[2] Since PE most commonly occurs as a complication of deep vein thrombosis (DVT), the physical examination should include an assessment of the lower extremities for erythema, tenderness, and/or swelling.

Physical Examination

Appearance of the Patient

The patient may appear anxious due to difficulty breathing. More severe cases may be associated with cyanosis.

Vital Signs

Temperature

The patient may have a low grade fever

Pulse

Rate

Tachycardia is present in 26% of the cases.^[2]

Rhythm

The pulse is regular.

Strength

The pulse may be weak if the patient is in shock.

Symmetry

The pulses are symmetric.

Respiratory Rate

Tachypnea is present in 70% of the cases.^[2]
Hypoxia may be present, but the hyperventilation associated with pulmonary embolism may actually drive down the PCO2.

Blood Pressure

The patient may be hypotensive secondary to circulatory collapse in cases of massive pulmonary embolism.^[1] The state of shock may progress to sudden cardiac arrest and or pulseless electrical activity in the absence of immediate management. Approximately 5% of all sudden cardiac arrest cases are attributed to pulmonary emboli.^[3]

Skin

Cyanosis may be present in the setting of massive pulmonary embolism.
Edema may be present in case of right heart failure.

Neck

Jugular venous distension may be seen in cases of massive pulmonary embolism.

Heart

Inspection

Parasternal heave secondary to the development of right ventricular failure may be present in massive PE.

Auscultation

Prominent P2 component of second heart sound may be present due to elevated pulmonary pressures.^[1]
Right sided S3 may be present in cases of a massive pulmonary embolism secondary to the development of right ventricular failure.
A murmur due to tricuspid regurgitation may be heard on auscultation.
Graham-Steell murmur is suggestive of pulmonary regurgitation.

Lungs

Reduced breath sounds may be present.
Rales may be present.
Crackles may be present.
Pleural friction rub may be present.
Pulmonary hypertension and RV overload are commonly seen during the physical exam and diagnosis.

Extremities

Signs of deep vein thrombosis may be present among patients with PE.^[1]

Unilateral calf or thigh tenderness
Unilateral calf or thigh pitting edema
Unilateral calf or thigh swelling
Difference in calf diameters > 3 cm (the calf circumference is measured 10 cm below the tibial tuberosity)
Difference in thigh diameters (the thigh circumference is measured 10-15 cm above the patella)
Unilateral calf or thigh warmth
Unilateral calf or thigh erythema
Palpable cord (a thickened palpable vein suggestive of thrombosed vein)
Dilatation of unilateral collateral superficial veins
Localized tenderness upon palpation of the deep veins
- Posterior calf
- Popliteal fossa
- Inner anterior thigh

Supportive Trial Data

The Prospective Investigation Of Pulmonary Embolism Diagnosis II (PIOPED II) study identified the following signs to be present in the majority of patients with a confirmed pulmonary embolism diagnosed by angiography.^[1]

Tachypnea (~54%),
Signs of deep venous thrombosis (~47%),
Tachycardia (~24%),
Rales (~18),
Reduced breath sounds (~17%),
Prominent P2 component of second heart sound (~15%),
Jugular venous pressure (~14%).
