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.
