Purpose:

The objective is to record and measure ventilations and using a

pneumograph and air temperature transducer. This would allow how ventilation

related to temperature change when inhalation and exhalation occur.

Background:

Breathing is essential for survival without it our bodies wont have any other

way of taking in oxygen and releasing CO2. If the human body is not inhaling or

exhaling, then the body would become hypoxic and death would happen. The way

how our body would be handling breathing is essential for survival. The apneic

drive that allow a person to hold their breath volunteer is very helpful when

preventing bad smells, water going into lungs or being stealth for survival.

The human body is an open system and the outside environment is needed to

support life. Inhaling air is needed to transport oxygen inside the body and CO2 out.

When inhaling air, air usually is colder than the inside of the human body. Thus, the

body has to warm the air while it being inhaled internally. Temperatures would be

very different at different period of breathing. By testing the lung capacity and

temperature, the conclusion of a generalized respiratory cycle idea is given.

Procedure:

A test subject should be sitting in a chair, with the heat transducer properly

placed. The respiratory transducer is also properly placed. For 15 seconds have the

test subject be seated and relaxed and record. Then have the subject hyperventilate

for 30 seconds and a recover from hyperventilating for 30 seconds. Then allow the

subject to Hypoventilation for 30 seconds and then recover for 30 seconds. Have the

subject cough and read aloud for 60 seconds.

Discussions:

The subject that was used was a young man that was very fit and healthy.

This allowed me to achieve results of a healthy man which would be different from

an infant to an elderly person. The experiment was a bit hassle to handle with.

Having the TA explaining it easily to me allowed me to reach the optimum data. The

subject would be breathing in normal but a bit inaccurate since I had to inform him.

It is hard to achieve an optimum breathing cycling since once informed the subject,

he would consciously volunteer control his breathing. Thus, eupnea breathing

would be either a little above normal or little below due to consciously breathing.

The addition I would add to the experiment would be to not inform the patient to

breath normal to get accurate results.

The subject was located in a room with inadequate ventilation. Thus, had a

higher temperature then compared to an area with colder air. When a person

inhales air into the body. The highest air temperature is the last part of the exhale

since it stayed longer inside the body. The difference in temperature wasn’t as much

due to above average room temperature in the testing room. This would affect our

results by having a lower Delta Change.

Conclusions:

The experiment went extremely well. The use of a fit subject allowed to get

an accurate results of a healthy person lung capacity and breath cycles be. The

computer system used in this experiment was working very precious and great

numbers were achieved. Delta T of the temperature was a little off due to the fact

that the room was higher temperature then it should have been due to inadequate

ventilation. And lastly if there wasn’t any information given to the subject to breath

normal, more accurate results would have been recorded due to the volunteer

inhalation and exhalation the subject subconsciously thought.
