Scenario 6 : Right Ventricle Strain

45yr woman is 10days staus post partial small bowel resection for Chron Disease and has been recuperating at home . She suddenly develops severe shortness of breath , becomes weak, and her Blood pressure drops to 80/40 from earlier 130/80. Pulse oximetry @ 89% on room air. While waiting for the Emergent medical service (EMS) to arrive, the APRN places EKG leads and the EKG demonstrates right ventricular Strain

Question: Explain Why a large pulmonary embolus causes right ventricular strain.

Please the answers should be 2-4 sentences NOT paragraphs.please provide intext citations used.

Answer 1

• Pulmonary embolism leads to increased right ventricle elevation which results in increased right ventricular tension.
• The right ventricle dysfunction reduces the right coronary artery blood flow and leads to increased oxygen demand.
• Decreased blood flow and increased oxygen demand leads to increased right ventricle wall tension.
• If it continues results in right ventricular strain.
