ARDS
This term describes the characteristic chest xray findings in ARDS
What is "white out" or ground glass opacities
Normal PH range for ABGs
What is 7.35 - 7.45
This ventilator setting helps regulate the amount of oxygen being given to the patient with each breath.
What is FiO2
The most important position to promote oxygenation and maximize lung expansion
What is high Fowler's position
This low flow oxygen device is commonly used for patients needing 1-6L/min of oxygen
What is nasal cannula
This is one of the key features of ARDS, which causes fluid accumulation in the alveoli impairing oxygen exchange
What is pulmonary edema
A PaCO2 >45 mmHg indicates this type of imbalance
What is respiratory acidosis
This ventilator setting controls the number of breaths per minute
What is rate (respiratory rate)
This intervention involves tapping on the chest to loosen mucous in patients with pneumona or cystic fibrosis
What is chest physiotherapy
This face mask can deliver 60-100% oxygen and has a reservoir bag
What is a non-rebreather mask
Name two common causes of ARDS?
What are sepsis and aspiration
What is the normal range for HCO3
What is 22-26 mEq/L
This ventilator parameter refers to the amount of air delivered per breath and is typically based on the patient's weight
What is tidal volume
Early sign of hypoxia
What is restlessness or confusion
This noninvasive ventilation method provides different pressures for inhalation and exhalation
What is BiPAP (Bilevel positive airway pressure)
This is a key lab marker or indicator used to monitor oxygenation in ARDS
What is the PaO2/FiO2 ratio
Identify the compensation pH 7.38, PaCO2 50, HCO3- 30
What is fully compensated respiratory acidosis
In patients with ARDS this ventilator setting can be adjusted to help prevent atelectasis by keeping pressure in the lungs positive at the end of expiration
What is PEEP (positive end expiratory pressure)
This intervention is essential to prevent ventilator associated pneumonia (VAP)
What is performing oral care every 2-4 hours
Before starting a patient on BiPAP, this lab value is especially important to evaluate the patient's acid-base and ventilation status
What is an ABG (arterial blood gas)
This patient positioning strategy, often used in severe ARDS, can improve oxygenation by enhancing ventilation-perfusion mismatch and reducing lung compression
What is prone positioning
ABG: pH 7.20, PaCO2 60, HCO3- 22. Interpret
What is uncompensated respiratory acidosis
The high-pressure vent alarm is sounding. List one potential cause and nursing intervention
What is airway obstruction e.g. secretions. Suction patient and assess for kinks in the tubing
A patient with a high respiratory rate on Bipap shows signs of fatigue and rising PaCO2. This intervention must be anticipated
What is intubation and mechanical ventilation
Name one key nursing responsibility when caring for a patient on CPAP or BiPAP
What is ensuring mask fit and skin integrity, or monitoring for aspiration risk
