| As anyone whose had a general anaesthetic will know, you have to cough and expectorate hard pretty much as soon as you come round to clear the anaesthetic out of your lungs. |
| Besides, who could like an instrument where all you do is expectorate into metal tubes! |
| Intake of these fluids will promote adequate hydration and help thin out mucus secretions, making it easier to cough up and expectorate. |
| A major advantage of sputum induction, however, is that patients who are normally unable to expectorate can almost always produce sputum after inhaling hypertonic saline. |
| According to an independent survey on spitting this year showed that 300 million Chinese expectorate in public. |
| If accidental contact occurs, flush mucosa with plenty of water and expectorate water. |
