Study Notes
Postoperative Care and Respiratory Management
- Patients with chronic lung disorders typically receive oxygen at low levels, usually not exceeding 2 L/min to prevent complications.
- Coughing and deep breathing exercises aid in lung expansion and secretion clearance. These should be performed together, rather than separately.
- Huff coughing is effective for mobilizing secretions and maintaining airway patency.
Oxygen Transport and Diffusion
- Approximately 97% of oxygen is transported from the lungs to tissues by hemoglobin as oxyhemoglobin.
- The remaining oxygen is dissolved in plasma and cells.
- Carbon dioxide, produced by cellular metabolism, is mainly transported as bicarbonate within red blood cells (65%) or combined with hemoglobin (30%).
Breathing Patterns and Airway Management
- Various abnormal breathing patterns include tachypnea (rapid), bradypnea (slow), apnea (cessation), Kussmaul’s (deep and labored), and Cheyne-Stokes (alternating deep/slow breaths).
- Signs of an obstructed airway may include low-pitched snoring, extreme inspiratory effort without movement, or retractions of the chest muscles.
Nursing Interventions for Respiratory Function
- Key nursing interventions include ensuring a patent airway, proper positioning, adequate hydration, and teaching deep breathing and coughing techniques.
- Incentive spirometry promotes pulmonary ventilation, loosens secretions, and helps expand collapsed alveoli, counteracting the effects of anesthesia.
Oxygen Delivery Systems
- Nasal Cannula: Delivers 1-6 L/min (24%-45% oxygen) but is not advisable beyond 6 L/min due to air swallowing.
- Simple Face Mask: Delivers 40%-60% oxygen at 5-8 L/min flow rates.
- Partial Rebreather Mask: Delivers 60%-90% oxygen at 6-10 L/min, utilizing an oxygen reservoir bag for rebreathing exhaled air.
- Non-Rebreather Mask: Provides 95%-100% oxygen at 10-15 L/min, equipped with a one-way valve to prevent air re-entry.
- Venturi Mask: Delivers specified oxygen concentrations (24%-50%) based on flow rates (4-10 L/min) through an interchangeable jet adapter.
Complications and Risks in Respiratory Care
- Potential complications of suctioning include hypoxemia and airway trauma.
- Maintaining a patent airway and preventing secretions accumulation are crucial to avoid respiratory distress.
Circulating Nurse Responsibilities in OR
- The circulating nurse facilitates surgeries by counting instruments and supplies, keeping the operating area organized, and preparing sterile supplies.
- They should wash hands thoroughly at the beginning of the day and maintain cleanliness throughout the procedure.
- Correct handling of specimens is essential, ensuring that small specimens are not crushed and that any contaminated materials are discarded properly.
