A patient is receiving gas containing 14 mg/L of water vapor at 20°C. The maximum capacity at 20°C is 17 mg/L.    

Which of the following factors increase evaporation in a humidifier? Higher gas temperature Greater surface area Longer contact time Greater thermal mass  

Which of the following are indications for humidity therapy? Dry medical gases Bypassed upper airway Bronchospasm caused by cold air Thick secretions  

Which statements regarding thermal mass are true? A greater volume of water increases thermal mass. Larger thermal mass improves heat transfer. Greater thermal mass helps maintain a stable gas temperature. Smaller thermal mass stores more heat.

A gas at 20°C contains 15 mg/L of water vapor. Maximum capacity at 20°C is 17 mg/L. Calculate the relative humidity.

Which factor has the greatest effect on the amount of water vapor a gas can hold?  

Which statements regarding bubble humidifiers are true? They contain a pressure-relief valve. Foam diffusers produce smaller bubbles than open-lumen tubes. Smaller bubbles improve humidification. They are ideal for mechanically ventilated patients.
