From the Guidelines
Management of tachypnea in a ward setting requires a systematic approach focusing on identifying and treating the underlying cause while ensuring adequate oxygenation, and instituting mechanical ventilation if oxygen supply becomes ineffective in correcting tachypnea and dyspnea, as recommended by the 2019 WSES guidelines 1.
Initial Assessment and Management
The first step in managing tachypnea is to assess the patient's vital signs, oxygen saturation, and work of breathing. Provide supplemental oxygen via nasal cannula (2-6 L/min) or face mask (5-10 L/min) to maintain oxygen saturation above 94% in most patients. Position the patient upright to optimize respiratory mechanics. Perform a focused history and physical examination to identify potential causes such as pneumonia, pulmonary embolism, heart failure, asthma, COPD exacerbation, or anxiety.
Investigations and Targeted Therapy
Order appropriate investigations including chest X-ray, ECG, arterial blood gases, complete blood count, and basic metabolic panel. For specific causes, initiate targeted therapy:
- for bronchospasm, administer salbutamol 2.5-5mg via nebulizer or 4-8 puffs via MDI with spacer every 20 minutes for three doses;
- for heart failure, give furosemide 40-80mg IV;
- for suspected infection, collect cultures and start empiric antibiotics like ceftriaxone 1-2g IV daily plus azithromycin 500mg daily.
Escalation of Care
Monitor the patient's response to treatment with serial vital sign checks and oxygen saturation measurements. If the patient shows signs of respiratory distress despite initial management, escalate care by calling for senior help or rapid response team. Institution of mechanical ventilation is recommended if oxygen supply becomes ineffective in correcting tachypnea and dyspnea, with a preference for lung-protective strategies 1. Non-invasive ventilation can be used, but invasive ventilation is mandatory when bronchial secretions clearance becomes ineffective and/or the patient is tiring or predicted to tire.
Additional Considerations
Non-pharmacological interventions such as education, respiratory training, and optimal positioning can be beneficial in managing dyspnea 1. Opioid usage as first-line treatment for dyspnea is recommended, with sedation with benzodiazepines or propofol considered as second line if dyspnea is not resolved with adequate doses of opioids 1. The use of non-medical strategies to decrease respiratory distress, such as optimal positioning and increased ambient air flows, should also be considered.
From the Research
Management of Tachypnea in a Ward Setting
The management of tachypnea, or rapid breathing, in a ward setting involves several key steps:
- Accurate measurement of respiratory rate as a fundamental part of assessment, as tachypnoea is one of the first signs of patient deterioration 2
- Assessment and management of tachypnoea, which is crucial in preventing further complications 2
Treatment Options
Treatment options for tachypnea may include:
- Oxygen therapy, with oxygen titration to no more than 94-96% for most acutely ill medical patients and to 88-92% in patients with acute chronic obstructive pulmonary disease (COPD) exacerbation 3
- Administration of medications such as albuterol, which has been shown to improve symptoms and peak flow rates in patients with bronchospastic disease 3
- Use of non-invasive positive pressure ventilation (NIPPV), which has been shown to be safe and effective in the treatment of respiratory distress due to acute pulmonary edema, bronchospasm, and other conditions 3
Airway Management
Airway management is a critical component of tachypnea management, and involves:
