Study Notes
Management of Acute Exacerbation
- Evaluating Arterial Blood Gas (ABG) is the first step in determining if a patient requires intubation or mechanical ventilation.
- Principles for initiating non-invasive positive pressure ventilation include:
- Identifying suitable patients
- Reviewing equipment with the patient and explaining care
- Fitting an appropriate-sized mask
- Adjusting the ventilator initially at low pressure (8-10 cm H2O inspiration; 4-5 cm H2O expiration)
- Asking the patient to report comfort level and adjusting ventilator pressures accordingly
- Adjusting oxygen flow rates to meet target oxygen saturation levels
- Adjusting the mask to avoid leaks
- Monitoring the patient frequently and coaching breathing patterns
- Gradually increasing inspiratory pressures for maximal relief of dyspnea
Tracheotomy
- Patients are evaluated for tracheotomy after 7 days of intubation
- If successful extubation appears unlikely during the next several days, tracheotomy is performed to promote patient comfort and early weaning from ventilatory support
- Longstanding endotracheal tube causes stenosis in the trachea
Additional Therapies
- Broad-spectrum antibiotics are used in conjunction with chest physiotherapy
- Systemic steroids are also used
Palliative and End-of-Life Care
- Most patients at the terminal stage of COPD choose not to use ventilator support or to use it only for a time-limited span
- Patients may opt for competent relief of terrifying dyspnea
Management of Acute Exacerbation
- Evaluating Arterial Blood Gas (ABG) is the most important first step to determine if the patient needs intubation or mechanical ventilation.
Noninvasive Positive Pressure Ventilation
- Identify suitable patients for noninvasive positive pressure ventilation.
- Review equipment with the patient and explain the care process.
- Fit an appropriate-sized mask for the patient.
- Initially set the ventilator to low pressure (8-10 cm H2O inspiration; 4-5 cm H2O expiration) with the patient holding the mask in place.
- Adjust ventilator pressures based on the patient's comfort level.
- Adjust oxygen flow rates to meet target oxygen saturation levels.
- Ensure a proper mask fit to avoid leaks.
- Frequently monitor the patient and coach breathing patterns.
- Gradually increase inspiratory pressures to provide maximum relief from dyspnea.
Tracheotomy
- Evaluate patients for tracheotomy after 7 days of intubation.
- If successful extubation is unlikely, proceed to tracheotomy to promote patient comfort and early weaning from ventilatory support.
- Longstanding endotracheal tube use can cause tracheal stenosis.
Additional Therapies
- Administer broad-spectrum antibiotics and chest physiotherapy.
- Use systemic steroids as part of the treatment plan.
End-of-Life Care
- Most patients in the terminal stage of COPD choose not to use ventilator support or opt for time-limited ventilator support if they can be assured of competent relief from dyspnea.
