BACKGROUND
Pulmonary embolism(PE) is the third greatest causeof mortality from cardiovascular disease, aftermyocardial infarction and cerebrovascular stroke.
At least 600,000 persons have been estimated tohave a pulmonary embolic event each year in theUSA.
Because pleural effusions occur in about 30% ofpatients with pulmonary emboli, 180,000 cases ofpleural effusion from pulmonary emboli shouldoccur annually
![Page 3: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/3.jpg)
PULMONARY EMBOLISM(PE)
Pulmonary embolism is a clinically significant obstruction of part or all of the pulmonary vascular tree usually caused by thrombus from distant site.

PULMONARY EMBOLISM
![Page 5: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/5.jpg)
PATHOPHYSIOLOGY OF PE
-The majority of clinically significant pulmonary embolibegin in the pelvic or lower extremity veins.
Initiated by
• Platelet aggregation around venous valvesinuses.
• Activation of the clotting cascade• Virchow's triad
venous stasis,injury to the vessel wall,and increased blood coaguability

DIAGNOSIS OF PULMONARY EMBOLISM(PE)
Clinical picture. Signs and symptoms Risk or predisposing factors for DVT Ventilation-perfusion mismatch Diagnostic Tests for PE.
-A chest radiograph -ECG-Ventilation-perfusion scanning (V/Q scanning). -Angiography-Spiral CT-D-dimer

Ventilation-perfusion Mismatch
By calculating A-a O2 gradient = PaO2 (alveolar) -PaO2 (arterial)
Normal A-a O2 gradient is 5-20 and increases with age.
-Elevated in 80% to 90% in PE
-Normal in 10% to 20% in PE
PAO2 (alveolar) = 150 - 1.2(PaCO2), assuming patient breathing room air
150 - 1.2 (40) = 102 150 –1.2 (35) = 108

Figure 1 Figure 2
Atelectasis
Atelectasis and parenchyma densities are quite common. Most of these densities are caused by pulmonary haemorrhage and edema
![Page 12: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/12.jpg)
Pleural Effusion
Pleural effusions are common and most often unilateral
occupying less than 15% of a hemithorax
![Page 13: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/13.jpg)
Elevated diaphragm
A diaphragm may be elevated, reflecting
volume loss in the affected lung.

Treatment of Pulmonary Embolism
Manage as for Respiratory Distress
- O2 monitoring,
- Fluid resuscitation for secondary right-sided heart failure,
- Inotropic Drugs.
Anticoagulant :Oral anticoagulant and LMWH.
Thrombolysis.
Caval Interruption.

PREVENTION OF PE
Postoperative DVT Prophylaxis
If not given prophylaxis, 15% to 30% of patients with abdominal surgery will develop a DVT.
DVT prophylaxis after surgery is cost effective and reduces the incidence of DVT and PE.
![Page 17: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/17.jpg)
Only low-molecular-weight heparin, intermittent pneumatic compression
devices and graded compression stockings have been shown to reduce
the incidence of pulmonary embolism.
![Page 18: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/18.jpg)
Pleural Effusionis the accumulation of abnormal volumes (>10-20ml) of fluid in the pleural space; the fluid-filled space that surrounds the lungs. Excess amounts of such fluid can
impair breathing by limiting the expansion of the lungs during respiration.
![Page 19: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/19.jpg)
PLEURAL EFFUSION DUE TO PULMONARYEMBOLISM
Pathophysiology
-The mechanism is usually increased interstitialfluid in the lungs as a result of ischemia or therelease of vasoactive cytokines or inflammatorymediators (e.g vascular endothelial growth factor) The excessive interstitial lung fluid traverses the visceral pleural
and accumulates into the pleural space
![Page 20: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/20.jpg)
PLEURAL EFFUSION DUE TO PULMONARY EMBOLISM
ON CHEST IMAGING Pleural effusions occur in 20–50% of patients with
pulmonary embolism Worsley and associates reviewed thechest radiographs of 383 patients in the ProspectiveInvestigation of Pulmonary Embolism Diagnosis (PIOPED I)study with angiographically proven pulmonary emboli andreported that 36% had a pleural effusion.
Two large multicenter studies comprising 2319 and 4033patients with pulmonary embolism reported that theincidence of pleural effusion was 23 and 21%, respectively,when assessed by chest radiograph.

Chest physiotherapy percussion
vibration
segmental deep breathing exercise
forced expiratory exercise
coughing techniques
![Page 38: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/38.jpg)
Physiotherapy management
Mechanism of CTTD drainage
Gravity as long as the chest drainage system is placed below the level
of the patient’s chest
Expiratory positive pressure from the patient push air and fluid out of the chest (e.g. incentive spirometer,
cough, Valsalva maneuver)
![Page 39: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/39.jpg)
Physiotherapy management
Care of CTTD
Ensure dependent drainage
Avoid kinks or obstruction
Avoid tube distraction or dislodgement
Observe volume and character of drainage during physiotherapy
Ambulation is advised when feasible
![Page 40: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/40.jpg)
Physiotherapy management
Brisk walking
Marching on the spot
Treadmill
Bicycle ergometry
Reduces fatigability and improves cardiopulmonary endurance
![Page 41: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/41.jpg)
PHYSIOTHERAPY INTERVENTION
It helps drain the excess fluid in the pleural space
Improves the lung function
Alleviate the breathlessness
Patient is ambulant with improve cardiopulmonary endurance and reduce fatigability
![Page 42: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/42.jpg)
Progression of management
TALK TEST is a method used for measuring exercise intensity. By judging your ability to talk during your work out at a low moderate pace(around a level 4-5 on the perceived exertion scale) if you are breathless, you are working out at a harder pace(around level 8-9)
AFTER 2WKS Patient was able to completely recite “the plegde” while
exercising at a low moderate pace AFTER 3WKSSerous fluid draining reduced in amountThe homogeneous opacity on x-ray also diminishing AFTER 4WKSPatient was able to workout at harder pace with less fatigue and
easily tiring out
![Page 43: Rehabilitation of patient with pleural effusion](https://reader034.fdocuments.net/reader034/viewer/2022042723/587ae4051a28ab542b8b6efd/html5/thumbnails/43.jpg)
CONCLUSION
Pleural effusions secondary to pulmonary embolism are mostly small and unilateral, but may become loculated if diagnosis is delayed.
Physiotherapy management and intervention is key to restoring patient back to fitness and functional independence
