Peak flow meter

http://www.mayoclinic.com/health/asthma/MM00399
A peak flow meter helps monitor respiratory conditions such as asthma, by measuring maximum airflow out of your lungs.
Procedure to use a peak flow meter?
1Slide the red piston to the bottom of the scale, next to the mouthpiece
2 Inhale deeply
3 then place your mouth over the mouthpiece and blow forcefully. Make sure your lips act as a seal over the mouthpiece so that no air escapes.

The red piston will slide up the scale. This is the reading.
Which reading do you record for a peak flow reading?
Take 3 readings, record the date time and the highest of the 3 readings
Peak flow readings are used for?
to MONITOR asthma, not to diagnose it. Spirometry's used to diagnose asthma.
Spirometry test?
http://www.youtube.com/watch?v=6kbgZWS5wH0
1 Put on a nose piece.
2 Inhale as much as can
3 Exhale into mouthpiece as fast as you can in the 1st second and make sure you exhale completely
x 3 times (for reproducibility)
How should the results of the spirometry test be reported?

http://www.nursingtimes.net/nursing-practice-clinical-research/procedure-for-the-assessment-of-lung-function-with-spirometry/205400.article
The best FEV1 and FVC results should be selected from three reproducible blows (these need not be from the same manoeuvre as long as results are within 100ml and five per cent of each other). The FEV1/FVC ratio should be calculated from the best VC reading, whether this is a relaxed or a forced manuver. Reference values and ranges should be reported. 3-8 tries. 30 sec b/t each.
Spirometry's helpful in diagnosing conditions such as?
helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD.
Reversibility test, or a post bronchodilator test (Post BD)?
Sometimes, to assess the reversibility of a particular condition, a bronchodilator is administered before performing another round of tests for comparison.
Important part in diagnosing asthma versus COPD.
A restrictive pattern affects lung expansion and is characterised by a ____ FEV1, a____ FVC and a _____ FEV1/FVC ratio?
A restrictive pattern affects lung expansion and is characterised by a LOW FEV1, a LOW FVC and a HIFH FEV1/FVC ratio..
An obstructive pattern is one which affects the rate at which air can be expelled from the lungs and is characterised by a ______ FEV1, _____ FVC and a _______ FEV1/FVC ratio.
An obstructive pattern is one which affects the rate at which air can be expelled from the lungs and is characterised by a REDUCED FEV1, NORMAL FVC and a LOW FEV1/FVC ratio.
Forced vital capacity (FVC)
represents the total amount of air exhaled at force from a maximum inhalation (total lung capacity) to maximum exhalation (residual volume), measured against time.
Tidal volume (TV)
is the volume of air inspired or expired in a single breath at rest
Total lung capacity (TLC)
is the maximum volume of air present in the lungs.
