Study Notes
Acid/Base Balance Monitoring
- pH value below 7.35 indicates acidosis.
- pH value above 7.45 indicates alkalosis.
- Measurements used for acid-base balance include arterial blood gases (ABGs) and PaCO2 levels; non-specific assessments do not apply.
- PaCO2 level reflects carbon dioxide retention, often associated with respiratory disorders.
- PaO2 value below 60 mmHg indicates severe hypoxemia, requiring urgent intervention.
- Adequacy of alveolar ventilation is gauged through the measurement of ETCO2 levels.
- Hypoventilation raises concerns for respiratory failure, requiring immediate evaluation.
Respiratory Syncytial Virus (RSV)
- Common symptoms of RSV include wheezing, coughing, and difficulty breathing.
- Peak incidence of RSV occurs in infants during the winter months, particularly affecting those under 1 year old.
- Leading cause of hospitalization in children under 1 year old is bronchiolitis caused by RSV.
- Primary management option for RSV bronchiolitis is supportive care, including hydration and monitoring.
Status Asthmaticus Management
- Common symptoms of status asthmaticus include severe shortness of breath, chest tightness, and rapid breathing.
- Medications used in management include:
- Inhaled beta-agonists to relax bronchial smooth muscles, with common side effects like tachycardia and tremors.
- Magnesium sulfate to reduce airway edema and enhance anti-inflammatory responses; target level is monitored closely.
- Adjunct therapies also include systemic corticosteroids.
- Non-management options do not include certain sedatives that could worsen respiratory function.
Other Considerations
- ETCO2 levels may increase due to hypoventilation, while conditions like hyperventilation can lead to decreased ETCO2.
- Research shows strong control of respiration is mediated by both central and peripheral chemoreceptors.
