Acute respiratory failure is a critical condition where the respiratory system fails in oxygenation, carbon dioxide elimination, or both. Hypoxemic respiratory failure, specifically, is characterized by inadequate oxygen exchange, leading to hypoxia. For nurses, prompt recognition and intervention are vital. This article delves into nursing diagnoses for acute respiratory failure with hypoxia, providing a comprehensive guide for effective patient care.
Understanding Acute Respiratory Failure and Hypoxia
Acute respiratory failure is not a disease itself but a consequence of various underlying conditions that impair lung function. It’s broadly categorized into hypoxemic and hypercapnic respiratory failure.
Hypoxemic Respiratory Failure (Type 1), also known as oxygenation failure, occurs when the lungs cannot adequately oxygenate the blood. The hallmark of hypoxemic respiratory failure is a partial pressure of arterial oxygen (PaO2) less than 60 mmHg, while the partial pressure of arterial carbon dioxide (PaCO2) is normal or low. Hypoxia, a condition of inadequate oxygen supply to tissues, is a direct consequence of hypoxemic respiratory failure.
Hypercapnic Respiratory Failure (Type 2), or ventilatory failure, involves inadequate carbon dioxide removal. PaCO2 is greater than 45 mmHg, leading to respiratory acidosis. While this article primarily focuses on hypoxemic respiratory failure with hypoxia, it’s important to differentiate it from hypercapnic failure.
Nurses play a crucial role in identifying at-risk patients, monitoring for early signs of respiratory distress, and implementing timely interventions. Effective nursing care is essential to stabilize the patient, address the underlying cause, and prevent further complications.
Nursing Assessment for Acute Respiratory Failure with Hypoxia
A thorough nursing assessment is the foundation of effective care. It involves gathering subjective and objective data to identify the patient’s condition and guide nursing diagnoses and interventions.
Review of Health History
1. Evaluate General Symptoms: Hypoxia and acute respiratory failure manifest through a range of symptoms:
- Changes in respiratory rate, depth, and rhythm (tachypnea, dyspnea, shallow breathing)
- Altered mental status (confusion, restlessness, lethargy, anxiety)
- Cyanosis or pallor (skin, nail beds, mucous membranes)
- Adventitious breath sounds (wheezing, crackles, stridor)
- Use of accessory muscles for breathing
- Decreased oxygen saturation (SpO2) levels
2. Determine the Underlying Cause: Several conditions can lead to acute respiratory failure with hypoxia:
- Pulmonary conditions: Pneumonia, acute respiratory distress syndrome (ARDS), pulmonary embolism, asthma exacerbation, chronic obstructive pulmonary disease (COPD) exacerbation, pneumothorax, hemothorax.
- Cardiac conditions: Heart failure, cardiogenic pulmonary edema.
- Neuromuscular disorders: Guillain-Barré syndrome, myasthenia gravis, spinal cord injury affecting respiratory muscles.
- Sepsis: Systemic infection leading to widespread inflammation and organ dysfunction, including the lungs.
- Trauma: Chest trauma, rib fractures, lung contusion.
- Drug overdose: Opioids, benzodiazepines causing respiratory depression.
3. Identify Risk Factors: Patients with pre-existing conditions are at higher risk:
- Pre-existing lung diseases: COPD, asthma, cystic fibrosis, interstitial lung disease.
- Heart conditions: Heart failure, coronary artery disease.
- Neuromuscular disorders: Conditions affecting respiratory muscle strength.
- Immunocompromised states: HIV/AIDS, organ transplant recipients, patients on immunosuppressants.

- Neuromuscular diseases (Guillain-Barré, myasthenia gravis)
- Connective tissue diseases (systemic lupus erythematosus, rheumatoid arthritis affecting lungs)
- Sleep apnea
7. Immune System Status: Immunocompromised patients are more susceptible to infections leading to respiratory failure.
8. Surgical History: Recent surgery, especially involving anesthesia or chest/abdominal procedures, increases the risk of:
- Atelectasis
- Pneumonia
- Pulmonary embolism
- Aspiration
Physical Assessment
1. Comprehensive Physical Examination: Observe for signs of hypoxia and respiratory distress across body systems:
- Central Nervous System (CNS): Altered mental status (restlessness, confusion, agitation, lethargy, coma), anxiety, seizures, diaphoresis.
- Head, Eyes, Ears, Nose, and Throat (HEENT): Central cyanosis (around lips and mucous membranes), blurred vision.
- Cardiovascular System: Tachycardia, arrhythmias, hypertension or hypotension, chest pain.
- Respiratory System: Dyspnea, tachypnea or bradypnea, shallow breathing, irregular breathing patterns (Cheyne-Stokes, Kussmaul’s), paradoxical breathing, pursed-lip breathing, use of accessory muscles, nasal flaring, retractions, grunting, cough (productive or non-productive), hemoptysis, abnormal breath sounds.
- Gastrointestinal System: Decreased appetite, nausea, vomiting, abdominal distension.
- Extremities: Peripheral cyanosis, digital clubbing (chronic hypoxia), peripheral edema, asterixis (flapping tremor indicating hypercapnia and metabolic disturbances).
2. Auscultation of Lungs: Carefully listen to breath sounds:
- Crackles (rales): Fluid in small airways or alveoli (pulmonary edema, pneumonia).
- Rhonchi: Secretions in larger airways (bronchitis, pneumonia).
- Wheezes: Narrowed airways (asthma, COPD exacerbation).
- Stridor: Upper airway obstruction (emergency).

Diagnostic Procedures
1. Arterial Blood Gas (ABG) Analysis: Gold standard for diagnosing respiratory failure and hypoxia.
- PaO2: < 60 mmHg indicates hypoxemia.
- PaCO2: Provides information on ventilation status.
- pH: Assesses acid-base balance.
- HCO3-: Bicarbonate level, part of acid-base assessment.
2. Blood Tests: To identify underlying causes and assess overall status:
- Complete Blood Count (CBC): Detect anemia (contributing to hypoxia), infection (elevated WBC).
- Electrolyte Panel: Imbalances can exacerbate respiratory failure.
- Cardiac Enzymes (Troponin, CK-MB): Rule out myocardial infarction as a cause.
- Brain Natriuretic Peptide (BNP): Assess for heart failure.
- D-dimer: Rule out pulmonary embolism.
- Sputum Culture and Sensitivity: Identify infectious agents in pneumonia.
3. Chest X-ray: Essential for visualizing lung pathology:
- Pneumonia (infiltrates)
- Pulmonary edema (Kerley B lines, cardiomegaly)
- Pneumothorax (pleural air)
- Pleural effusion (fluid in pleural space)
- ARDS (bilateral infiltrates)
4. Bedside Lung Ultrasound (BLUE Protocol): Rapid, non-invasive diagnostic tool in emergency settings for dyspnea and hypoxemia.
5. Electrocardiogram (ECG): If cardiac etiology is suspected; detect arrhythmias, ischemia.
6. Pulmonary Function Tests (PFTs): Once stable, to assess lung volumes and capacities, helpful in chronic conditions.
7. Bronchoscopy: For direct visualization of airways, obtain samples, remove foreign bodies, in selected cases.
Common Nursing Diagnoses for Acute Respiratory Failure with Hypoxia
Based on the assessment findings, several nursing diagnoses may be appropriate for a patient with acute respiratory failure and hypoxia. These diagnoses guide the development of individualized care plans. Key nursing diagnoses include:
- Impaired Gas Exchange: Related to alveolar-capillary membrane changes, ventilation-perfusion mismatch, disease processes, evidenced by hypoxemia (PaO2 < 60 mmHg, SpO2 < 90%), hypercapnia (PaCO2 > 45 mmHg), altered mental status, cyanosis, and abnormal breathing patterns.
- Ineffective Breathing Pattern: Related to respiratory muscle fatigue, neuromuscular impairment, pain, anxiety, evidenced by dyspnea, tachypnea, bradypnea, altered depth of respiration, use of accessory muscles, nasal flaring, and abnormal ABGs.
- Ineffective Airway Clearance: Related to excessive secretions, decreased energy/fatigue, impaired cough reflex, airway spasm, evidenced by adventitious breath sounds (rhonchi, wheezes, crackles), ineffective cough, inability to remove secretions, and dyspnea.
- Activity Intolerance: Related to imbalance between oxygen supply and demand, generalized weakness, evidenced by exertional dyspnea, fatigue, weakness, abnormal heart rate or blood pressure response to activity.
- Anxiety: Related to hypoxia, fear of suffocation, dyspnea, threat to physiological integrity, evidenced by restlessness, irritability, apprehension, verbalization of fear, and physiological symptoms of anxiety (tachycardia, tachypnea).
These are primary nursing diagnoses directly related to the respiratory compromise. Depending on the individual patient’s condition and underlying causes, other diagnoses may also be relevant, such as:
- Risk for Aspiration: Related to decreased level of consciousness, impaired cough/gag reflex, presence of feeding tubes.
- Deficient Fluid Volume or Excess Fluid Volume: Related to underlying conditions (heart failure, renal failure), and management of respiratory failure.
- Imbalanced Nutrition: Less Than Body Requirements: Related to increased work of breathing, decreased appetite, and underlying illness.
- Risk for Infection: Related to invasive procedures (intubation, mechanical ventilation), suppressed immune system.
- Disturbed Sleep Pattern: Related to dyspnea, anxiety, hospital environment, and medical interventions.
- Powerlessness: Related to inability to control breathing, dependence on mechanical ventilation, critical illness environment.
- Compromised Family Coping: Related to patient’s critical illness, uncertain prognosis, and emotional distress.
Nursing Interventions for Acute Respiratory Failure with Hypoxia
Nursing interventions are directed at correcting hypoxemia, supporting ventilation, treating the underlying cause, and preventing complications.
1. Optimize Oxygenation:
- Administer Oxygen Therapy: Start with the least invasive method (nasal cannula) and escalate as needed (simple face mask, non-rebreather mask, high-flow nasal cannula, mechanical ventilation). Titrate oxygen to maintain SpO2 of 90% or greater and PaO2 > 60 mmHg.

- Monitor Oxygen Saturation and ABGs: Regularly assess response to oxygen therapy and adjust accordingly.
- Positioning: Elevate head of bed (semi-Fowler’s or high-Fowler’s) to promote lung expansion. Prone positioning may be considered in severe ARDS.
- Breathing Exercises: Teach and encourage deep breathing and coughing exercises to improve ventilation and clear secretions (if appropriate and patient is able).
2. Support Ventilation:
- Mechanical Ventilation: Prepare for and assist with intubation and mechanical ventilation if non-invasive methods are insufficient to correct hypoxemia or hypercapnia, or if the patient has respiratory muscle fatigue or altered mental status.
- Non-Invasive Ventilation (NIV): Consider NIV (CPAP, BiPAP) for selected patients with COPD exacerbation, cardiogenic pulmonary edema, or obesity hypoventilation syndrome, if appropriate and before intubation becomes absolutely necessary.
- Ventilator Management: Collaborate with respiratory therapists to optimize ventilator settings, monitor for complications (ventilator-associated pneumonia, barotrauma), and wean as appropriate.
3. Promote Airway Clearance:
- Suctioning: Perform oropharyngeal or tracheal suctioning as needed to remove secretions and maintain a patent airway.
- Humidification: Ensure adequate humidification of inspired air to prevent drying of mucous membranes and facilitate secretion removal.
- Chest Physiotherapy and Postural Drainage: Consider chest physiotherapy and postural drainage to mobilize secretions (if appropriate and patient is stable).
- Encourage Coughing: Assist and encourage effective coughing techniques.
4. Treat Underlying Cause:
- Administer Medications: Administer medications as prescribed to treat the underlying cause of respiratory failure, such as antibiotics for pneumonia, bronchodilators and corticosteroids for asthma or COPD exacerbation, diuretics for pulmonary edema, thrombolytics or anticoagulants for pulmonary embolism, and reversal agents for drug overdose.
- Manage Cardiac Conditions: Optimize cardiac function if heart failure is contributing to respiratory failure.
- Sepsis Management: Implement sepsis protocols, including antibiotics, fluid resuscitation, and source control if sepsis is the cause.
5. Optimize Hemodynamics and Fluid Balance:
- Fluid Management: Monitor fluid balance carefully. Fluid overload can worsen pulmonary edema, while dehydration can compromise cardiac output and tissue perfusion.
- Hemodynamic Monitoring: Monitor blood pressure, heart rate, and other hemodynamic parameters. Consider invasive monitoring (arterial line, central venous catheter) in unstable patients.
- Medications: Administer vasoactive medications (vasopressors, inotropes) as prescribed to support blood pressure and cardiac output.
6. Provide Comfort and Psychosocial Support:
- Pain Management: Assess and manage pain effectively. Pain can increase respiratory distress.
- Anxiety Management: Address anxiety related to dyspnea and critical illness. Provide reassurance, calm environment, and consider anxiolytics as prescribed.
- Communication: Communicate clearly and effectively with the patient and family. Explain procedures and treatments.
- Emotional Support: Provide emotional support to the patient and family during this stressful time. Consider involving social work and pastoral care services.
7. Prevent Complications:
- Ventilator-Associated Pneumonia (VAP) Prevention: Implement VAP prevention bundle (HOB elevation, oral care, suctioning, sedation vacation, DVT/stress ulcer prophylaxis).
- Deep Vein Thrombosis (DVT) Prophylaxis: Administer pharmacological or mechanical DVT prophylaxis.
- Skin Care: Prevent skin breakdown, especially in patients with decreased mobility or edema.
- Nutritional Support: Provide adequate nutritional support (enteral or parenteral) to meet metabolic demands and promote healing.
