Study Notes
Generalized Wheezing and Assessment Findings
- Symptoms include tachycardia, retractions, restlessness, and anxiety.
- Respiratory signs encompass inspiratory stridor, expiratory wheezing, hypoxemia, hypercapnia, and cough with sputum production.
- Expiratory prolongation and cyanosis indicate severe respiratory distress.
- Elevated pulsus paradoxus: systolic blood pressure during expiration exceeds inspiration by over 10 mmHg.
Diagnostic Studies
Laboratory Assessments
- Arterial oxygen level (PaO2) may decrease during asthma attacks, while early arterial carbon dioxide level (PaCO2) may be low; late stages show an increase in PaCO2.
Peak Flow Monitoring
- Peak flow meters measure airflow during forced expiration.
- Color-coded zones for peak flow results:
- Green Zone: 80%-100% of personal best.
- Yellow Zone: 60%-80%.
- Red Zone: less than 60%, requiring immediate action.
Status Asthmaticus
- Episodes can lead to respiratory failure and potential complications like pneumothorax.
- Increasing PaCO2 indicates worsening condition, a primary concern in status asthmaticus.
Medical Management
- Close monitoring of the patient and therapy responses is crucial.
- Treatment typically involves:
- Short-acting beta2-adrenergic agonists (e.g., albuterol).
- Systemic corticosteroids prescribed for severe cases.
- Supplemental oxygen is usually administered during acute attacks.
Respiratory Distress Syndrome and ARDS
- Refractory hypoxemia is a key feature of ARDS, where hypoxemia persists despite oxygen administration.
- ABG tests show hypoxemic conditions with decreased PaO2.
- Pulmonary function tests reveal reduced lung compliance and vital capacity.
Mechanical Ventilation Strategies
- Indicated if non-invasive ventilation (NIV) fails to support oxygenation or ventilation.
- Ventilation strategies include lung protective ventilation (tidal volume: 4-8 mL/kg).
- Continuous renal replacement therapy (CRRT) or sustained low-efficiency dialysis (SLED) for patients with acute kidney injury.
Vaccination for SARS-CoV-2
- Vaccines such as BNT162b2 (Pfizer/BioNTech) are recommended to prevent symptomatic COVID-19 infection.
- Assess exposure to COVID-19 cases within defined timeframes to evaluate risk.
Cultural Sensitivity in Patient Assessment
- Cultural beliefs and norms play a significant role in patients' responses to illnesses and should be considered in healthcare delivery.
