Accurate respiratory assessment forms the foundation of safe nursing care. Begin by observing the patient's breathing pattern, rate, and depth. Note any signs of respiratory distress, such as nasal flaring, use of accessory muscles, or pursed-lip breathing.
Auscultation of breath sounds requires a systematic approach, moving from the apices to the bases of the lungs, comparing side to side. Adventitious sounds like crackles, wheezes, or pleural friction rubs provide crucial clues about underlying pathology. Always pair physical findings with continuous pulse oximetry monitoring to track arterial oxygen saturation trends.
A clear airway is vital for adequate gas exchange. When patients cannot clear thick secretions independently, nursing intervention is required.
Never perform routine suctioning without clinical indication, as it can cause mucosal trauma and hypoxia. Pre-oxygenate the patient before suctioning whenever possible.
Oxygen is a medication and must be administered with care. Low-flow devices like nasal cannulas provide variable oxygen concentrations, while high-flow devices like Venturi masks deliver precise fractions of inspired oxygen (FiO2).
| Device | Typical Flow Rate | Approximate FiO2 |
|---|---|---|
| Nasal Cannula | 1 - 6 L/min | 24% - 44% |
| Simple Face Mask | 5 - 10 L/min | 40% - 60% |
| Venturi Mask | Specific to adapter | 24% - 50% |
| Non-Rebreather Mask | 10 - 15 L/min | 60% - 90% |
Monitor patients receiving oxygen therapy for signs of oxygen toxicity or drying of the mucous membranes. Humidification is necessary when delivering oxygen at higher flow rates to protect the airway epithelium.
Medications manage bronchospasm, inflammation, and infection in respiratory illness. Bronchodilators relax airway smooth muscle, opening narrowed passages. Short-acting beta-agonists like salbutamol provide rescue relief during acute asthma attacks, whereas long-acting agents maintain baseline control.
Anti-inflammatory agents, particularly inhaled corticosteroids, reduce airway edema and mucus hypersecretion in chronic conditions like asthma and chronic obstructive pulmonary disease. Teach patients the correct technique for using metered-dose inhalers and emphasize rinsing the mouth after corticosteroid use to prevent oral candidiasis.
Managing acute respiratory distress requires rapid, decisive action. Position the patient in high Fowler's or an upright forward-leaning posture to maximize chest expansion. Administer prescribed oxygen and stay with the patient to reduce anxiety, as panic worsens dyspnea.
For chronic conditions, care shifts toward energy conservation and preventing exacerbations. Teach pursed-lip breathing to prolong exhalation and keep airways open longer, reducing air trapping. Monitor fluid balance carefully, as dehydration thickens secretions while fluid overload worsens pulmonary congestion.
Long-term success in managing chronic respiratory diseases depends heavily on patient education. Teach individuals to recognize early warning signs of an exacerbation, such as increased fatigue, changes in sputum color, or worsening shortness of breath.
Pulmonary rehabilitation programs combine exercise training, breathing techniques, and nutritional counseling to break the cycle of breathlessness and inactivity. Encourage patients to pace their daily activities and use energy-saving methods. A supportive, knowledgeable patient manages their condition with greater confidence and fewer hospital readmissions.
