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.

The answer for this would be option 3. Based on the topographic map given above which shows three drumlins, the direction of the advancing ice movement that created these drumlins and the arrangement of sediments is <span>south to north ice movement, and unsorted sediments. Hope this answer helps.</span>
If you come acrosson-scene of a 56-year-old female patient
experiencing cardiac arrest. The first airway you should administer is the Oropharyngeal
airway. Oropharyngeal airway or oral airway for short is known as a medical
device considered to be an airway adjunct, which is used to open a patient’s
airway and refrain it from being obstructed by the tongue. It prevents the
tongue from covering the epiglottis, which could hinder the patient from
breathing, when a person turns unconscious, the muscles in the jaw relaxes and
allows the tongue to block the airway.
I would say from a forward straight answer to describe very specific identitys like, the type of lizard, color, length, what it likes to eat, etc. :)
