12 Questions
What is the recommended threshold for hypoxemia in adults based on PaO2 levels?
Less than 60 torr
In which type of patients is poor oxygenation common, leading to a suspicion of hypoxemia?
Postoperative patients
When is O2 therapy alone considered insufficient to treat hypoxemia?
When the P/F ratio drops below 200
What is the main recommended treatment when O2 therapy alone is insufficient due to shunting?
Applying CPAP or PEEP
Which method can help raise the PaO2 level in patients with refractory hypoxemia?
Using patient positioning to decrease shunting
What is the defining factor when considering the use of CPAP or PEEP in treating hypoxemia?
$PaO_2$ levels
What is the primary goal when titrating FIO2 (fraction of inspired oxygen) in patients?
To maintain a PaO2 of 80-100 torr with saturation ≥ 92%
In emergency settings for conditions like carbon monoxide poisoning, acute pulmonary edema, or myocardial infarction, what is the recommended FIO2?
Provide the highest possible FIO2
For patients with chronic hypercapnia, what is the recommended target range for PaO2?
55-60 torr
What is the recommended target range for PaO2 in low-birth-weight or preterm neonates at risk for retinopathy of prematurity (ROP)?
50-80 torr
When suctioning a patient on invasive ventilatory support for hypoxemic respiratory failure/ARDS, which method is recommended to prevent ventilator disconnection?
Both an inline/closed catheter system and a bronchoscope ventilator adapter are recommended
What is the recommended duration for each suctioning attempt when suctioning a patient?
10-15 seconds
Learn about the signs and symptoms of hypoxemia that indicate the need for starting oxygen therapy, as well as the criteria for documented hypoxemia. Understand the threshold for initiating oxygen therapy and the potential hazards associated with it.
