- Check your knowledge on gas laws and metrics
What is the flow of nasal cannula ?
(1 L - 6 L )/ min
Up to 60 L/min
6 L - 10 L / min
Up to 600 L / min
What is HFNC
New method for delivering heated and humidified oxygen gas through a nasal cannula.
Predict risk of intubation at 2, 6 and 12 hours in hypoxemic respiratory failure.
Provide oxygen at flow rates that are lower than patients' inspiratory demands
This is the most common method of delivery for home use and provides flow rates of 2 to 6 liters per minute (LPM)
ROX index is
The ratio of SpO2/FIO2 to respiratory rate is used to predict outcome of Nasal High Flow Cannula therapy (HFNC).
ROX score greater than or equal to 4.88 measured at 12 hours predicts lower risk of progressing to mechanical ventilation.
Optimal excitation of the ROX dye at ~575 nm and hence a strong ROX signal.
Treatment in which a storage tank of oxygen or a machine called a compressor is used to give oxygen to people with breathing problems.
How much value should ROX index predict to avoid intubation
ROX <4.88
ROX >4.88
ROX >2.82
ROX <2.82
Which law is For a given temperature the mass of a gas that dissolves (not chemically combine) in a specific volume of a liquid is directly proportional to the product of the partial pressure of the gas and its solubility coefficient
Daltonโs Law
Henryโ Law
Fickโs Law
Grahams Law
