Care of Patients with Cor Pulmonale and Lung Cancer Flashcards
Causes:
Right-sided HF: enlargement of RV due to high BP in lungs usually causes by chronic lung disease; increased pressure in pulm artery backs into RV and blood backs into SVC and backs up into body
Symptoms/Assessment/CM
Diagnostic
Treatment/Nursing Care
Cor pulmonale
Specifically Right sided heart failure caused by pulmonary disease (ex. emphysema or pulmonary hypertension)
When something damaging the lungs become fibrotic/fibrosis/pulm HTN in pulm artery when that happens and increased work that right side heart has do to pump blood out is cor pulmonale - increased work and right side heart can hypertrophy and can have issues
Increased vascular resistance in the lung causes the right side of the heart to work harder against the increased pressure
The right side of the heart enlarges and can cause a backflow of blood into the venous system - comes from body into rt side heart and when harder for heart pump out from RV backs up into body
Causes: - Cor pulmonale
Need be aware for when caring
Hypoxemia - see with lot resp diseases; hypoxia - decreased oxygenation to tissues
Dyspnea - common
Cyanosis - common
Vein distention - unique; specifically JVD; backflow of blood back into body from rt side of heart
Systemic edema - unique
Acidosis - see with emphysema and COPD pats
Fatigue - SOB and lack oxygen
Enlarged liver - unique; backflow of blood into body
Chest pain - common one with these pats
Symptoms/Assessment/CM - Cor pulmonale
Arterial blood gas (ABG)
Brain natriuretic peptide (BNP)
Echocardiogram
Right heart catherization
Ventilation Perfusion scan(V/Q scan)
Diagnostic - Cor pulmonale
Assess for hypoxia and hypoxemia and acidosis
Arterial blood gas (ABG)
Assesses the function of the heart; heart has do increased work and gets fluid overload BNP peptide that gets released; increased levels with increased work of the heart/worsening HF
<100 not diagnostic of HF; grade based on how high; 900-1000 sig HF
Commonly check for pats
For Cor pulmonale/any heart failure; lab value: serum blood draw
Brain natriuretic peptide (BNP)
Assess for heart function
US of heart
Looking at ejection fraction (EF): % volume in LV ejected with each contraction of the heart; indicative of how heart is pumping
Echocardiogram
Assess for pulmonary artery pressures
Imp for cor pulmonale - check pulm artery pressures; common cause of cor pulmonale; pulm artery HTN can occur without any predisposing factors but can also occur with lung disease
Right heart catherization
Compares how ventilating and how well tissues perfused; if mismatch in that could be indication that heart not pumping effectively and getting oxygenated blood to tissues
Ventilation Perfusion scan(V/Q scan)
Medications
Oxygen therapy
Heart/Lung transplant
Treatment/Nursing Care - Cor pulmonale
Big with them
Endothelin receptor antagonist - block vasoconstriction and allow vessels to dilate which means less resistance heart pumping against; common seen
Prostaglandin agents
Calcium channel blockers
Diuretics
Anticoagulants
Medications
Prostaglandin agents that dilate the pulmonary arteries are given on a continuous infusion that can not be stopped; decrease pressure rt side heart pumping against
Prostaglandin agents
Education required for patients and caregivers
Typ given at late stages of cor pulmonale and lot edu because if pumps ever stopped pat could die - make sure always kept going and anyone caring for them has all info needed regarding pump and how refill it
Pat gets lot info on it as well because have it at home as well
Prostaglandin agents that dilate the pulmonary arteries are given on a continuous infusion that can not be stopped; decrease pressure rt side heart pumping against
Vasodilate
Calcium channel blockers
Get kidneys get rid extra fluid on board
Diuretics
Sometimes if pat at risk for clots
Anticoagulants
Very common because decreased efficiency of heart; tissues not getting as much O2 so supplement
Oxygen therapy
Endstage HF esp if cor pulmonale caused by lung disease see have heart and lung transplant; need transplant both so not go back into cor pulmonale
Heart/Lung transplant
Leading cause of cancer deaths worldwide
One most common cancers die from - worst if diagnosed in later stage and already metastasized
Poor long-term survival due to late-stage diagnosis
Staged to assess size and extent of disease (metastasis)
2 Types:
Causes
Symptoms/Assessment
Diagnostic
Treatment/Nursing Care
Palliative treatment
Chest tubes
Lung cancer
Small cell lung cancer (SCLC) - treatment is chemo and pats not good outcome with that
Non small cell lung cancer (NSCLC) - typ pats have better prognosis because lend to more surgical interventions which have a better prognosis
2 Types: - Lung Cancer
Exposure to inhaled irritants over time - lot resp diseases like this
Cancer cells arise from the bronchial epithelium secondary to irritation/inflammation
Genetic predisposition
Causes - Lung Cancer
Chronic exposure causitive factor
Smoke, asbestos, coal, air pollution – any sort of pollutant/irritant can lead to lung cancer
Number pats no predisposing factors; irritants cause it because causes cancer cells to proliferate and because irritation to bronchial lining
Cigarette smoke is the most common
Exposure to inhaled irritants over time - lot resp diseases like this
Dyspnea - SOB; hypoxia and hypoxemia
Persistent cough or change in cough - might have cough if chronic lung disease; ask if change in cough; big one that lung cancers s/s unique is hemoptysis and hoarseness
Hemoptysis/Rust colored sputum
Hoarseness
Pain (chest, back, shoulder, pleuritic) - go along with once metastasize because tendency to metastasize to bone and brain; bone = start have pain in back and shoulder
Decreased lung sounds where mass is located and dullness when percussed; wheezing if there is obstruction - large enough tumor cause dullness during percussion; also have diminished lung sounds because not as much air moving in and out of lungs because tumor taking over too much of lung
Recurrent pleural effusions
Late signs: - like with any cancer
Symptoms/Assessment - Lung Cancer
Collection of fluid in the pleural space
Common in lung cancers - how diagnose
Thoracentisis (drain fluid) and run for cytology and come back for carcinoma; happen beginning and as progress at end stage have large ones that even if palliative care drain for symptom management with dyspnea
Recurrent pleural effusions
Weight loss; fatigue; dysphagia; anorexia; difficulty eating
Late signs: - like with any cancer
