A group of occupational-related lung diseases characterized by inflammation, infection, and bronchitis, caused by inhaling substances in the workplace is called <u>Occupational asthma.</u>
<h3>Occupational asthma:</h3>
A specific form of asthma called occupational asthma is brought on by inhaled irritant exposure during work. Since occupational asthma frequently has a reversible course, avoiding the triggers may cause the symptoms to go away.
Inhaling compounds referred to as triggers might cause asthma symptoms in people with sensitive airways. Several industrial chemicals can cause asthma symptoms, which can result in occupational asthma. The most frequent triggers include chemicals, fungi, animal dander, wood dust, grain dust, or grain dust.
Symptoms of occupational asthma include wheezing, shortness of breath, runny nose, nasal congestion, eye discomfort, and tightness in the chest. When exposed to the irritant(s) at work, these symptoms may develop worse.

Answer:
ECG paper is a grid where time is measured along the horizontal axis.
Each small square is 1 mm in length and represents 0.04 seconds.
Each larger square is 5 mm in length and represents 0.2 seconds.
Voltage is measured along the vertical axis.
10 mm is equal to 1mV in voltage.
The diagram below illustrates the configuration of ECG graph paper and where to measure the components of the ECG wave form
Heart rate can be easily calculated from the ECG strip:
When the rhythm is regular, the heart rate is 300 divided by the number of large squares between the QRS complexes.
For example, if there are 4 large squares between regular QRS complexes, the heart rate is 75 (300/4=75).
The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10.
For example, if there are 7 R waves in a 6 second strip, the heart rate is 70 (7x10=70).
Answer:
