Answer:
anecdotal evidence
Explanation:
Anecdotal evidence has to do with evidence gotten in an informal which is backed up by personal testimony and it may not be regarded as a piece of scientific evidence because it has to do with word of mouth.
Therefore, having critical thinking about media reports of research needs the researcher to be familiar with this anecdotal evidence as it relies on personal testimony.
Some examples of an anecdotal evidence is
- Wow! This wonder drug completely cured me of cancer.
- I drank heavily for years but my kidney is fine. I'm sure alcohol does not affect the kidney.
Answer:
A peak expiratory flow (PEF) measurement
Explanation:
The peak expiratory flow (PEF), or peak expiratory flow rate (PEFR), is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breath out air. It measures the airflow through the bronchi and thus the degree of obstruction in the airways. Peak expiratory flow is typically measured in units of liters per minute (L/min).
Measurements may be based on 1 second or less but are usually reported as a volume per minute. Electronic devices will sample the flow and multiply the same volume (Liters) by 60, divided by the sample (seconds) for a result measured in L/minute: (sample volume*60)/sample time.
Peak flow readings are often classified into 3 zones of measurement according to the American Lung Association, green, yellow, and red.
Green zone: 80 to 100 percent of the usual or normal peak flow readings are clear. A peak flow reading in the green zone indicates that the asthma is under good control.
Yellow zone: 50 to 59 percent of the usual or normal peak flow readings. Indicates caution. It may mean respiratory airways are narrowing and additional medication may be required.
Red zone: less than 50 percent of the usual or normal peak flow readings. Indicates medical emergency. Severe airway narrowing may be occurring and immediate action needs to be taken. This would usually involve contacting a doctor or hospital.
