Respiratory alkalosis is a loss of carbon dioxide (Pco2 <>2CO3) due to a marked increase in the rate of respiration. The two primary mechanisms that trigger hyperventilation are hypoxemia and direct stimulation of the central respiratory center of the brain.
Compensatory mechanisms include decreased respiratory rate (if the body is able to respond to the drop in Paco2), increased renal excretion of bicarbonate, and retention of hydrogen. It is the most frequently occurring acid-base imbalance in hospitalized patients, with the elderly at increased risk because of high incidence of pulmonary disorders and alterations in neurological status.

What is Respiratory Alkalosis?
Respiratory alkalosis is a medical condition characterized by a reduction in the levels of carbon dioxide (CO2) in the bloodstream, resulting in an imbalance in the body’s acid-base equilibrium. This leads to an increase in blood pH above the normal range (typically greater than 7.45). Respiratory alkalosis occurs when the respiratory system eliminates CO2 from the body at a faster rate than it is produced, causing a decrease in the concentration of carbonic acid (H2CO3) and subsequent alkalinity.
Causes of Respiratory Alkalosis
Respiratory alkalosis can be caused by various factors that increase breathing rate or decrease CO2 production, including:
- Hyperventilation: Breathing at an abnormally rapid rate, often due to anxiety, stress, pain, or high altitudes, leads to excessive elimination of CO2.
- Fever: Elevated body temperature can increase metabolic rate, leading to hyperventilation and lowered CO2 levels.
- Hypoxemia: Low oxygen levels, often due to lung diseases or high altitudes, can trigger increased breathing and respiratory alkalosis.
- Mechanical Ventilation: Overventilation during mechanical ventilation can result in excessive removal of CO2 from the body.
- Altitude: At higher altitudes, the partial pressure of oxygen in the air is lower, leading to hypoxia. The body compensates by increasing ventilation, which can result in respiratory alkalosis.
Symptoms of Respiratory Alkalosis
The symptoms of respiratory alkalosis can vary in severity and presentation. Here’s a list of common symptoms:
- Hyperventilation: Rapid and deep breathing, or hyperventilation, is a hallmark symptom of respiratory alkalosis. Increased ventilation causes excessive elimination of CO2 from the body, leading to a decrease in blood CO2 levels.
- Dizziness and Lightheadedness: Hyperventilation reduces the levels of CO2 in the blood, which can affect cerebral blood vessels and brain perfusion. The resulting constriction of blood vessels can lead to dizziness and lightheadedness.
- Tingling and Numbness (Paresthesia): Alkalosis can affect calcium ionization in the blood, which influences nerve cell excitability. This alteration in ionized calcium levels can result in sensations of tingling or numbness, often starting in the extremities and around the mouth.
- Muscle Spasms and Cramps: Decreased CO2 levels can result in the constriction of blood vessels supplying muscles. This can lead to muscle spasms, particularly in the hands and feet.
- Confusion and Anxiety: Altered pH and electrolyte imbalances can affect neurological function. Respiratory alkalosis can lead to confusion, anxiety, irritability, and difficulty concentrating.
- Chest Discomfort and Palpitations: Changes in blood pH can affect the electrical conduction system of the heart. This might lead to palpitations, chest discomfort, or a sensation of tightness.
- Increased Blood Pressure: Respiratory alkalosis can lead to constriction of blood vessels due to changes in ionized calcium levels, which might result in elevated blood pressure.
Nursing Care Plans and Management
Nursing care plans and management for respiratory alkalosis are integral aspects of patient care, especially in cases where individuals experience an imbalance in their body’s acid-base equilibrium.
Nursing Problem Priorities
Nursing care for patients with respiratory alkalosis involves addressing the underlying causes, managing symptoms, and restoring acid-base balance. Prioritizing nursing problems is essential to focus on the most critical issues for patient care. Here are nursing problem priorities for patients with respiratory alkalosis:
- Inadequate Gas Exchange: Rapid breathing and hyperventilation in respiratory alkalosis can disrupt the normal exchange of oxygen and carbon dioxide in the lungs. This can lead to decreased oxygen saturation, inadequate oxygen delivery to tissues, and impaired removal of carbon dioxide.
- Anxiety and Dyspnea: Patients experiencing respiratory alkalosis may feel anxious, agitated, and breathless due to the hyperventilation-induced decrease in CO2 levels. Addressing anxiety and alleviating dyspnea is essential for patient comfort and improved respiratory function.
- Electrolyte Imbalance and Neuromuscular Changes: Alkalosis can affect ionized calcium levels, leading to symptoms such as paresthesia (tingling or numbness), muscle spasms, and tetany. Addressing electrolyte imbalances is important to prevent complications like muscle weakness and arrhythmias.
- Patient Education and Breathing Techniques: Educating the patient about the causes of respiratory alkalosis, its effects, and the importance of managing breathing patterns is essential. Teaching relaxation techniques and proper breathing strategies can help control hyperventilation.
- Positioning and Comfort: Helping patients find comfortable positions will promote efficient breathing, ease anxiety and contribute to reducing hyperventilation.
- Nutritional Support and Maintenance of Calcium Levels: Providing proper nutrition and calcium intake can help maintain electrolyte balance and prevent complications associated with alkalosis-induced changes in calcium levels.
Nurses play a crucial role in assessing and diagnosing patients with respiratory alkalosis to identify underlying causes, monitor changes in respiratory status, and facilitate appropriate interventions. Thorough assessment and accurate diagnostic findings are essential for the effective management of the condition. Here’s a comprehensive overview of nursing assessment and diagnostic findings in patients with respiratory alkalosis:
- Health History: Assess for factors such as anxiety, stress, fever, pain, hyperventilation triggers, and underlying lung conditions that could contribute to hyperventilation and respiratory alkalosis.
- Patient Interview and History: Gain insights into potential triggers for hyperventilation, such as anxiety, stress, fever, pain, or recent altitude changes.
- Respiratory Rate and Pattern: Observe the patient’s breathing rate, depth, and pattern for signs of hyperventilation. Rapid and deep breathing indicates excessive ventilation.
- Cardiac Assessment: Monitor heart rate and rhythm for potential arrhythmias due to electrolyte imbalances caused by alkalosis.
- Neurological Assessment: Evaluate for symptoms of paresthesia (tingling/numbness) or muscle spasms, which can result from changes in ionized calcium levels due to alkalosis.
- Level of Consciousness and Anxiety: Assess for altered mental status, confusion, irritability, and signs of anxiety due to cerebral vasoconstriction from respiratory alkalosis.
- Arterial Blood Gas (ABG): ABG results will show an elevated blood pH (alkalosis) and decreased partial pressure of carbon dioxide (PaCO2) due to excessive ventilation.
- Calcium Levels: Blood tests might reveal decreased total or ionized calcium levels, contributing to symptoms like muscle spasms.
- Respiratory Monitoring: Continuous monitoring of respiratory rate, depth, and effort is crucial to assess hyperventilation and respiratory distress.
- Electrocardiogram (ECG): ECG results might show signs of arrhythmias related to alkalosis-induced electrolyte imbalances.
- Oxygen Saturation: Assess oxygen saturation to ensure adequate tissue oxygenation despite respiratory alkalosis.
Nursing care for patients with respiratory alkalosis focuses on addressing the underlying causes and improving respiratory function. Setting specific and measurable nursing goals helps guide patient care and ensures a holistic approach to managing respiratory acidosis. Here are the nursing goals for patients with respiratory alkalosis:
- The patient’s arterial blood gases (ABGs) will demonstrate a normalized PaCO2 and improved oxygen saturation.
- The patient will verbalize decreased feelings of anxiety and discomfort related to hyperventilation.
- The patient will demonstrate controlled and normalized respiratory rate and depth.
- The patient will verbalize decreased sensations of tingling and numbness, along with a reduction in muscle spasms.
- The patient’s serum calcium levels will remain within the normal range.
- The patient will demonstrate an understanding of relaxation exercises to manage hyperventilation and anxiety.
- The patient’s electrocardiogram (ECG) results will show a stable heart rhythm, and blood pressure will remain within acceptable parameters.
- The patient will identify factors that contribute to hyperventilation and explain techniques to manage or prevent it.
- The patient will adhere to prescribed interventions, medications, and therapies aimed at addressing the underlying cause of respiratory alkalosis.
Nursing Interventions and Actions
Nursing care for patients with respiratory alkalosis involves a range of interventions and actions aimed at addressing the underlying causes and improving respiratory function. Here is a comprehensive list of nursing interventions and actions for patients with respiratory alkalosis:
1. Promoting Effective Gas Exchange
Respiratory alkalosis leads to compromised oxygen-carbon dioxide balance in the bloodstream, impairing the body’s ability to efficiently exchange gases due to an altered respiratory rate. This disturbs the equilibrium between oxygen and carbon dioxide levels, hindering the normal gas exchange process in the lungs.
Assess the patient’s respiratory rate, depth, and effort. Observe for signs of hyperventilation, such as rapid and shallow breathing.
Close monitoring allows for early detection of hyperventilation episodes, enabling timely interventions to prevent severe respiratory alkalosis and its potential complications.
Continuously monitor oxygen saturation using pulse oximetry to ensure adequate oxygenation
Monitoring oxygen saturation levels helps identify any compromised gas exchange and enables prompt adjustments to interventions or oxygen therapy.
Assist the patient in finding a comfortable position, such as elevating the head of the bed or sitting upright. Provide pillows or supports to maintain proper alignment and lung expansion.
Proper positioning aids in optimizing lung expansion, allowing for improved air exchange and oxygenation, which is especially important in managing respiratory alkalosis.
Administer supplemental oxygen as prescribed
Oxygen therapy ensures adequate oxygen supply to tissues and supports respiratory efforts, particularly in cases where hyperventilation leads to oxygen imbalances.
Create a calming environment and offer emotional support to reduce anxiety and stress that can trigger hyperventilation.
Emotional distress can contribute to rapid breathing and alkalosis.
Encourage the patient to breathe slowly and deeply. Speak in a low, calm tone of voice. Provide a safe environment.
May help reassure and calm the agitated patient, thereby aiding the reduction of respiratory rate. Assists patient to regain control.
Instruct the patient to practice slow, controlled breathing exercises. Teach techniques such as diaphragmatic breathing, which can help normalize respiratory rate and prevent excessive carbon dioxide loss.
low, deliberate breathing helps counteract hyperventilation, reducing the risk of respiratory alkalosis by maintaining a more balanced acid-base state.
Collaborate with a respiratory therapist
Respiratory therapists can guide the patient in personalized breathing exercises and techniques to normalize respiratory patterns.
2. Reducing Anxiety
Anxiety in patients with respiratory alkalosis can arise from the physiological impact of hyperventilation, leading to decreased carbon dioxide levels, which can trigger cerebral vasoconstriction and heightened sympathetic nervous system activity, resulting in sensations of restlessness, palpitations, and feelings of apprehension or unease.
