CV 2
- Most common type of heart failure
- Failure of the left side of the heart
- 2 Categories
- Systolic Heart Failure
- LV contractility is not great enough to maintain CO
- Early Stage Compensation
- Decreased CO
- Decreased BP
- RAAS stimulation
- Increased Na+ reabsorption
- Increased blood Osm
- Increased ADH
- Increased H2O absorption
- Thirst
- Increased fluid intake
- Increased BV
- Increased blood entering the heart per beat
- Heart wall stretches
- Increased Angiotensin II
- Arterial vasoconstriction
- Increased TPR
- Increased sympathetic output
- Increased contractility
- Increased SV
- Increased CO
- Increased BP
- Arterial vasoconstriction
- Increased TPR
- Diastolic Heart Failure
- 3 Effects
- 1 Decreased LV compliance
- 2 Increased resistance
- 3 Backflow into pulmonary circulation
- Principle Sign
- Pulmonary Edema
- Fluid build up w/i lungs
- 4 Consequences
- 1 Decreased gas dexchange
- 2 Dyspnea
- 3 Cyanosis
- 4 Respiratory acidosis
- Decreased blood pH due to increased CO2
- Blue skin due to decreased O2
- 4 Treatments
- 1 Diuretics
- 2 Inotropic Drugs
- Increase contractility
- 3 Intra-aortic Balloon Pump
- Helps push blood through systemic
circulation to reduce workload on heart
- 4 LV Assist Device
