Mo's Monday Minute: Factors Worsening Orthostatic Hypotension for Nurses

Understanding Orthostatic Hypotension

• 🎯 Orthostatic hypotension is a condition that can lead to a patient being at high risk for falls and injury.
• 💡 This episode focuses on specific factors that can exacerbate orthostatic hypotension, making it crucial for nurses to be aware of them.

Factors Causing Vasodilation and Reduced Cardiac Output

• 🌡️ Hot weather can worsen orthostatic hypotension because blood vessels dilate to dissipate heat, which can lower blood pressure.
• 💧 A fluid volume deficit, whether from decreased intake, diuresis (e.g., furosemide), or fluid losses from vomiting, diarrhea, or weeping wounds, significantly exacerbates the condition.
• 🍻 Alcohol intake contributes by having a diuretic effect and causing vasodilation, both of which can worsen orthostatic hypotension.

Impact of Immobility and Prolonged Postures

• 🚶 Prolonged standing can lead to blood pooling in the lower extremities, weakening vein valves and increasing venous distension, which can worsen orthostatic hypotension.
• 🛏️ Prolonged bed rest contributes to cardiovascular deconditioning and impaired hormonal responses to blood pressure changes, making patients more susceptible when they do get up.

Key Takeaways for Nurses

• 📌 Nurses should be aware that hot weather, fluid volume deficits, alcohol intake, prolonged standing, and prolonged bed rest are key factors that can worsen orthostatic hypotension.
