Respiratory Acidosis
Clinical presentation:
- Cardiovascular:
Hypotension
Delayed cardiac conduction that can lead to heart block, peaked T waves, prolonged PR intervals, and widened QRS complexes
Peripheral vasodilation with thready, weak pulse
Tachycardia
Warm, flushed skin
- Respiratory:
Dyspnea, may have hypoventilation with hypoxia
- CNS:
Headache, seizures, altered mental status, papilledema, muscle twitching, drowsiness -> coma
-Diagnostics:
Decreased pH, elevated PaCO2
Hyperkalemia.
- Compensation:
Increased rate and depth of respirations to blow off CO2
Kidneys eliminate H ions and retain HCO3
HCO3 levels rise when body attempts to compensate
With partial compensation, pH remains decreased
With full compensation, pH returns to normal
- Priority Nursing Diagnoses:
Ineffective breathing pattern R/T hypoventilation
Impaired gas exchange R/T alveolar hypoventilation
Sensory-perceptual alterations R/T acid-base alterations
Anxiety R/T breathlessness
Risk for injury R/T decreased LOC
Risk for decreased CO R/T dysrhythmias
- Management:
Treatment directed at underlying cause and improving ventilation
Implement pulmonary hygiene measures
Provide adequate fluid intake
Administer supplemental oxygen cautiously in client with chronic respiratory acidosis
Mechanical ventilation if necessary
- Planning and Implementation:
Assess respiratory rate and depth
Monitor for complications and response
Assess for tachycardia and irregularities
Monitor ECG for dysrhythmias
Monitor serum electrolytes and ABGs
Administer oxygen as indicated and ordered
- Planning and Implementation:
Administer medications as ordered and indicated:
Bronchodilators to decrease bronchospasm
Antibiotics to treat infections
Respiratory agents to decrease viscosity of secretions
Anticoagulants and thrombolytics
Provide good oral hygiene frequently
Maintain safe positioning
- Planning and Implementation:
Keep a calm, quiet environment
Assess for cyanosis
Orient confused client frequently
Position to facilitate maximum lung expansion
Provide adequate fluid intake
