BT_PO 1.38 Define humidity and outline the importance of humidification
Not a riveting topic, but giving dry gas to a patient can cause problems, so you need to know something about it.
T/F at a relative humidity of 100%, a litre of gas at 21 degrees Celcius will contain the same amount of water as a litre of gas at 37 degrees Celcius
T/F In an awake person, during quiet nasal breathing, humidification of inhaled air occurs in the upper airway
T/F Airway lining fluid acts as heat and moisture exchanger during respiration
T/F Relative humidity levels need to be monitored and controlled in the operating theatre
T/F Administration of dry gases may impair surfactant activity
