2.2 Hieronder is ‘n prentjie wat ‘n baie belangrike proses illustreer. Alle lewende organismes benodig hierdie proses om te oorleef.  Bestudeer die prentjie en beantwoord die vrae wat volg.   OM DIE PRENTJIE TE SIEN, KLIEK OP DIE BLOKKIE, SODAT DIT IN ‘N NUWE VENSTER OOPMAAK:    

A patient with a reduced FEF 25-75 and an increased Total lung capacity and residual volume has which of the following conditions?

The % predicted pre-bronchodilator FVC:

For questions #29-32 – Using the chart provided below, answer the following. Pulmonary Mechanics Predicted Value Actual Value FVC 5.1 5.0 FEV 1               4.2 2.8 FEV1/FVC %              80% 56% FEF 25-75%               3.6 1.26 The patient is a 30-year-old, 6-foot male.  Using the chart, and assuming the spirometer corrects for BTPS, complete the following:   29.  The % predicted for FVC is:

A patient has a Vital Capacity of 3400ml.  His functional residual capacity (FRC) is 2000 ml and his expiratory reserve volume (ERV) is 1000 ml.  What is his residual volume?

If the FEV1/FVC % is 80-100%, we interpret this as:
