The FRC‚ the amount of air left in the lungs after complete exhalation‚ decreased by .7 L because expiration is occurring much more forcefully. This leaves less air behind on the lungs. ERV+RV=FRC.

PRACTICAL 1 Aim: To use a spirometer to investigate the effects of exercise on lung volume. Spirometer Spirometry is the most basic and frequently performed test of pulmonary (lung) function. A device called a spirometer is used to measure how much air the lungs can hold and how well the respiratory system is able to move air into and out of the lungs. A spirometry test is done with a spirometer‚ which consists of a mouthpiece and disposable tubing connected to a machine that records the results

silent for a second before the Doctor looks up at me and replies‚ “your results have come back...I’m sorry Jason; it seems you have lung cancer”. “Currently there is nothing we can really do and I’ve discussed your case with specialist in the field and we have predicted that you may not have that long left”. Two words‚ two words are all it took to destroy my life‚ lung cancer .My body instantly became numb and my stomach felt as if it had exploded. I stared at the ground my eyes becoming out of focus

Using a spirometer to investigate human lung function The purpose of this activity is: • to show how a spirometer can be used to find the vital capacity of lungs and to calculate important subdivisions of this capacity. • to show how to interpret the trace resulting from use of a spirometer • to consider how to use a spirometer to estimate metabolic rate. Procedure SAFETY: Do not use a spirometer unless supervised by a teacher. If you are using the spirometer and you experience

out during normal breathing is about 500 mL‚ this volume of air is called the tidal volume.In addition‚Vital capacity is the largest volume of air an individual can move in and out the lungs.Human Lung capacity can be measured in many different ways‚ one way of measuring human lung capacity is by using a ballon.The purpose of this experiment is to determine the vital capacity of your lungs and to understand the relationship between tidal and reserve respiratory volumes.

Plethysmography is used to measure changes in volume in different parts of the body. This can help check blood. The test may be done to check for blood clots in the arms and legs‚ or to measure how much air you can hold in your lungs. Lung plethysmography: You will breathe or pant against a mouthpiece. Clips will be put on your nose to shut off your nostrils. Depending on the information your doctor is looking for‚ the mouthpiece may be open at first‚ and then closed. You will be breathing
