Resp Mechanics Lab 1

Respiratory mechanics 1 Note at that place is an phantasm in your testing ground book The scratch radius for the pay heed pipework diameter should be 5mm in each look into and NOT 6mm. Use your computer touch on to ADAm for this part of this weeks lab. You argon also responsible for the PowerPhys lab report. Measuring Normal Respiratory Volumes 1) estimate the minute respiratory passel apply the tidal volume and breaths per minute (pump rate). 2) desex the following terms a. Respiration- The act of breathing, inhaling and exhaling. b. Alveoli- turn up at the ends of the bronchiole, send sacs in the lungs where the change of oxygen and carbon dioxide takes place. . Diaphragm- the partition separating the pectoralcavity from the abdominal cavity. http//dictionary. reference. com/browse/ stoppage In the following table are the information calculated during a dependant air course test. Use these data to answer the following questions. FEV1 as % of full of life elec trical capacity Radius FEV1 Vital Capacity FEV1 (%) 5 3541 4791 73. 9 4. 5 2503 3143 73. 3 4 1422 1962 72. 4 3. 5 822 1150 71. 4 3 436 621 70. 2 3) What affect does bring down the radius of the air flow tube on respiratory volumes? Reducing radius of the air flow tube decreases respiratory volume.personal effects of Surfactant on Respiratory Volumes 4) How does bed wetter affect the tidal volume? It minimizes push through stress in the alveoli which makes it easier for the alveoli to increase come forth field of operations for gas exchange. 5) How does addition of bed wetter affect the total air flow into the lungs? It affects the total airflow because it allows the air flow into the lungs to be increased because resistance is lowered. 6) why does surfactant have the affect that it does on total air flow? It minimizes the tension at the surface, which allows the alveoli to increase surface area for gas exchangewe force out occur more and easily. ) Emphysema is a lung stipula tion that results in a(n) in the tidal volume of the lungs. d. Emphysema decreases tidal volume of the lungs. Effects of Thoracic Cavity Puncture 8) What happens in pneumothorax? Pneumothorax is also called a collapsed lung. A collapsed lung can occur for a number of reasons. It could be a result of an injury, a health check condition, or it can happen without reason. It occurs when there is a build up of air around the lungs, and this causes pressure, which keeps the lung from expanding to its normal capacity when breathing.
