Study Notes
Short-Acting Inhaled Beta2-Adrenergic Agonists (SABA)
- SABAs like albuterol and levalbuterol provide quick relief during acute asthma symptoms by relaxing smooth muscle.
- Accessory muscle use and engorged neck veins indicate respiratory distress, worsening can lead to absent wheezing, suggesting impending respiratory failure.
- Anticholinergics such as Ipratropium help reduce airway vagal tone but do not provide immediate relief as SABAs do.
- Corticosteroids are the most potent anti-inflammatory medications for asthma management amid acute exacerbations.
Oxygen Therapy
- Supplemental oxygen is frequently used in status asthmaticus, delivered via mask, nasal cannula, or endotracheal tube.
- Early recognition of refractory hypoxaemia is crucial; it is the hallmark of Acute Respiratory Distress Syndrome (ARDS).
- Oxygen therapy should be administered to maintain adequate saturation, with progression to high flow nasal oxygen or mechanical ventilation if necessary.
Critical Care in COVID-19 Patients
- Continuously monitor airway patency, oxygen saturation (>90%), vital signs, and indicators of infection.
- Positioning patients in semi-Fowler's helps improve breathing; patient repositioning every two hours minimizes complications.
- Administer oxygen to achieve target SpO2, escalating from nasal cannula to non-invasive or invasive ventilation as required.
- Elevate the foot of the bed and encourage isometric exercises to prevent pressure sores.
Pneumonia
- Pneumonia is characterized by lung inflammation caused by various microorganisms including bacteria and viruses.
- It is classified into types: Community-Acquired Pneumonia (CAP), Healthcare-Associated Pneumonia (HCAP), Hospital-Acquired Pneumonia (HAP), and Ventilator-Acquired Pneumonia (VAP).
- Clinical manifestations include acute chills, fever, productive cough, and chest pain; older patients may show atypical signs.
Diagnostic Tests for Pneumonia
- Chest X-ray identifies fluid, infiltrates, and atelectasis in lung tissue.
- CT scans provide detailed imaging for diagnosis.
- Monitoring for respiratory distress is critical as it can indicate worsening pneumonia.
Pulmonary Embolism (PE)
- Most commonly caused by blood clots; other emboli may include air, fat, or amniotic fluid.
- Symptoms include pain in extremities, warmth, and redness. Assessing health history is key for risk evaluation.
- Monitor vital signs and lab results during thrombolytic therapy to avoid complications.
Management of Pain and Nursing Care
- Positioning patients in semi-Fowler's and frequent repositioning can help with pain management.
- IV catheters should not be left in place for extended durations to prevent infection.
- Fluid intake, nutrition, and completion of prescribed medications should be emphasized for recovery.
Health Education for Home Care
- Importance of adhering to medication regimens and recognizing activity limitations to prevent exacerbations.
- Encouragement of fluid intake to facilitate mucus clearance, along with nutritional support for overall health recovery.
