Blood Pressure Management in End-of-Life Care

The Bloodpressure Program™ By Christian Goodman The procedure is a very basic yet effective method to lessen the effects of high blood pressure. To some people, it sounds insane that just three workouts in a day can boost fitness levels and reduce blood pressure simultaneously. The knowledge and research gained in this blood pressure program were really impressive.

In end-of-life care, blood pressure (BP) management becomes less focused on achieving specific numerical targets and more centered around comfort, symptom relief, and quality of life. Patients at the end of life, especially those with advanced chronic illnesses such as heart failure, cancer, chronic kidney disease, or advanced age, may experience fluctuations in BP due to organ failure, medications, and progressing disease processes. The goal of blood pressure management in this context shifts from aggressive treatment to maintaining comfort and dignity during the patient’s final days.

1. Importance of Blood Pressure Monitoring in End-of-Life Care

Although aggressive BP control may not be a priority in end-of-life care, monitoring BP remains important for the following reasons:

Assessing symptom burden: BP fluctuations can be associated with symptoms such as pain, dyspnea (difficulty breathing), or lightheadedness. Monitoring BP helps assess the progression of these symptoms.
Managing comfort: Sudden drops in BP can cause discomfort, such as dizziness, confusion, or weakness, which can be alleviated with appropriate interventions (e.g., fluid management, pain control).
Identifying clinical deterioration: Significant changes in BP can indicate worsening clinical conditions, such as cardiovascular collapse, sepsis, or organ failure, prompting decisions about end-of-life care planning and interventions.
Guiding treatment decisions: BP readings can help guide decisions about whether interventions (e.g., vasopressors, IV fluids) are appropriate, depending on the patient’s overall goals of care.

2. Blood Pressure Changes in End-of-Life Patients

As patients approach the end of life, BP typically decreases due to several factors:

Decreased cardiac output: As the heart weakens, especially in conditions like heart failure or advanced cancer, the ability to maintain a normal BP diminishes.
Multisystem failure: In patients with multiple organ failures (e.g., liver, kidneys, heart), BP may fluctuate or progressively fall.
Autonomic dysfunction: The body’s ability to regulate BP may be impaired, especially in advanced neurological diseases such as Alzheimer’s disease, Parkinson’s disease, or spinal cord injuries.
Medications: Opioids, sedatives, and other medications used in palliative care can affect BP by causing hypotension, sedation, or bradycardia.

3. Target Blood Pressure in End-of-Life Care

In end-of-life care, the target BP is less about achieving specific readings and more about managing symptoms and comfort:

Hypotension: A gradual decrease in BP, particularly in the terminal stages, is common and often expected. The focus is not to raise the BP to normal levels unless there is evidence of severe discomfort or life-threatening symptoms (e.g., acute coronary syndrome or septic shock).
Hypertension: If elevated BP is present due to pain, anxiety, or fluid retention, the goal is to treat the underlying cause to improve comfort rather than aggressively managing BP with medications.
Comfort and symptom control: The treatment approach should aim for palliation (symptom relief) rather than cure or aggressive treatment. Blood pressure management should be tailored to the patient’s comfort, preferences, and goals of care.

4. Managing Blood Pressure in Specific Scenarios

A. Severe Hypotension (Low Blood Pressure)

If BP drops significantly, especially in the terminal phase, the response is focused on comfort:

IV fluids may be administered to increase intravascular volume, but the emphasis is on managing any underlying symptoms (e.g., nausea, dizziness) rather than correcting BP to normal ranges.
Vasopressor medications (e.g., norepinephrine, dopamine) may be considered in cases of shock or severe symptomatic hypotension, but these should be used sparingly and in alignment with the patient’s goals of care, especially if they are in a do-not-resuscitate (DNR) or comfort care plan.
Positioning the patient (e.g., elevating legs or using a head-down tilt) may help improve BP and comfort, but the overall goal remains alleviating discomfort.

B. Hypertension (High Blood Pressure)

Elevated BP in end-of-life patients may be a result of pain, fluid overload, or stress:

Pain management with opioids, such as morphine, is often used to relieve the pain and anxiety that can elevate BP.
Diuretics may be administered if fluid retention is contributing to elevated BP, but care should be taken to avoid excessive fluid shifts.
In cases of terminal cancer, neurological disorders, or heart failure, antihypertensive medications may be adjusted or withheld, as aggressive BP reduction may not align with the goals of care and could lead to unnecessary side effects.

C. Medications and Comfort

Medications used to manage BP in palliative care should focus on comfort rather than strict BP control:

Opioids: Commonly used for pain and symptom relief, opioids may lower BP and should be carefully titrated to balance pain relief with hypotension risks.
Sedatives/Anxiolytics: Drugs like benzodiazepines (e.g., lorazepam) may help relieve anxiety and distress, potentially lowering BP in the process.
Antiarrhythmics and Inotropes: These are used selectively if there is cardiac instability or life-threatening arrhythmias, but they should be avoided if they do not align with comfort-oriented care goals.

5. Patient and Family-Centered Care

In end-of-life care, the emphasis is on honoring the patient’s wishes and goals for treatment. Discussing BP management with the patient (if possible) and their family or healthcare proxy is essential:

Advance directives and palliative care plans should be reviewed regularly to ensure that BP management is in line with the patient’s values and preferences.
Communication is critical: healthcare providers should ensure that families understand that BP is no longer the primary target for treatment but rather the relief of symptoms, improvement in comfort, and respect for the natural process of dying.

6. Conclusion

Blood pressure management in end-of-life care should focus on comfort, symptom management, and quality of life rather than aggressive interventions to normalize BP. Although monitoring BP is important, interventions should be tailored to the patient’s goals, the progression of their illness, and their symptom burden. The primary goal in this setting is to manage discomfort—whether that be from pain, dyspnea, or nausea—and to ensure that the patient is able to pass with dignity and as little distress as possible. Patient autonomy and the involvement of the healthcare team in making these decisions are critical to delivering compassionate and effective end-of-life care.
