If a factor in raising the productivity of labor is not used in the production process, it is referred to as a reserve for increasing labor productivity. Reserves are classified according to their association with a particular production process, an economic sector, or the national economy.
Definition. 1  Urinary catheterization is the insertion of a catheter into a patient's bladder. The catheter is used as a conduit to drain urine from the bladder into an attached bag or container.
Catheterisation means to introduce a catheter into a body cavity to inject or remove fluid. Urinary catheterisation reduces the risk of infection and kidney damage by ensuring the bladder is emptied adequately continuously or at regular intervals. Catheterisation can be used on a temporary basis to help people retrain their bladder, and it may also be needed after certain kinds of surgery.
