Study Notes
Respiratory Disorders
- Vital signs are monitored during procedures like arterial blood gas sampling and chest tube insertion.
- Supplemental oxygen is provided if needed, and the patient should be observed for signs of distress.
- Placing the patient in a sitting position with raised arms or a side-lying position can improve breathing.
Pulmonary Failure
- A life-threatening condition where the lungs fail to meet the body's oxygen needs.
- Characterized by low oxygen levels in the blood (PaO2 < 50 mmHg), high carbon dioxide levels (PaCO2 > 50 mmHg), and an arterial pH below 7.35.
- Causes include decreased respiratory drive due to brain injury, sedation, or metabolic disorders, dysfunction of the chest wall, impairment in gas exchange, and acute respiratory distress syndrome (ARDS).
Acute Respiratory Distress Syndrome (ARDS)
- A sudden and progressive form of respiratory failure with severe dyspnea, persistent low blood oxygen levels, and widespread lung inflammation.
- It progresses through three stages: exudative, proliferative, and fibrotic.
- Early signs include restlessness, dyspnea, low blood pressure, confusion, and extreme tiredness.
- Late signs include severe difficulty breathing, shortness of breath, tachycardia, thick frothy sputum, cyanosis, abnormal breath sounds, and decreased carbon dioxide levels.
- Risk factors include direct pulmonary trauma, indirect pulmonary trauma, pneumonia, and sepsis.
Chest Tube Insertion
- The insertion site is typically in the triangle of safety, located in the mid-axillary line between the 4th or 5th intercostal space.
- The procedure is performed under sterile conditions and with close monitoring of the patient's vital signs.
- After the procedure, the patient is placed in a side-lying position with the unaffected side down for at least an hour.
- The chest tube is connected to a drainage system, which can be a one-bottle, two-bottle, three-bottle, or Pleurovac system.
Chest Tube Drainage System
- The drainage system uses gravity, underwater seal, and suction to remove air, fluid, and blood from the pleural space surrounding the lungs.
- The principles of chest tube drainage include gravity to drain fluid, underwater seal to prevent air from entering the pleural space, and suction to help re-expand the lung.
Ventilator-Associated Pneumonia (VAP)
- Common complication in patients on mechanical ventilation.
- Caused by colonization of invasive devices with bacteria.
- Prevention strategies include avoiding cross-contamination, decreasing aspiration risk, maintaining a closed system setup for ventilation circuitry, and ensuring adequate nutrition.
Allen’s Test
- Evaluates the arterial blood flow to the hand, typically for the ulnar or radial artery.
- The procedure involves clenching the fist, applying pressure to both the ulnar and radial arteries, releasing pressure on the ulnar artery, and observing for the return of circulation to the skin within 5-10 seconds.
Modes of Ventilation
- Spontaneous ventilation occurs when the patient breathes independently without machine assistance.
- Controlled ventilation is where the machine controls the patient's breathing, overriding their spontaneous effort.
- Synchronized Intermittent Mandatory Ventilation (SIMV) allows the patient to breathe spontaneously while receiving preset breaths from the machine.
- Assist-controlled ventilation is when the machine assists the patient's breaths, triggered by their inspiratory effort.
