What is ARDS? - ARDS is an unexpected, catastrophic, pulmonary complication occurring in a person with no previous pulmonary problems. Clients are critically ill and are managed in an intensive care setting. The mortality rate is high (50%). Interventions to prevent complications of clients on mechanical ventilation with ARDS: - Elevate HOB to at least 30 degrees. Assist with daily awakening- "sedation vacation" Implement a comprehensive oral hygiene program. Implement a comprehensive mobilization program When do you suction? - Only when secretions are present Before drawing a sample for ABG's from the radial artery. what test do you perform? - Perform the Allen test to assess collateral circulation. Make the client's hand blanch by obliterating both the radial and ulnar pulses. Then release the pressure over the ulnar artery only. If flow through the ulnar artery is good, flushing will be seen immediately. The Allen test is then positive, and the radial artery can be used for puncture. If the Allen test is negative, repeat on other arm. If this is also negative, seek another site for radial puncture. The Allen test ensures collateral circulation to the hand if thrombosis of the radial artery should follow the puncture Cardinal signs of ARDS in children: - Restlessness, tachypnea, tachycardia, diaphoresis What levels signify respiratory failure with O2 and CO2? - PCO2 45, PO2 60 on 50% O2. How much oxygen should a child be on if in severe distress? - 100% O2 What are early signs of shock? - Agitation and restlessness resulting from cerebral hypoxia Describe what happens with severe shock and its pathophysiology
