Is Step Down Med-Surg?
Step-down nurses provide patient care in transitional units where patients are too sick for the med-surg floor but not sick enough for intensive care. Their comprehensive medical and nursing knowledge is supplemented by technical familiarity with advanced telemetry equipment, competence with emergent situations.

What is PCU material?
7.6 Polycarbonate Urethane (PCU) Polyurethane material was first used in humans as an acetabular cup by Dr Charles Townley in 1960 . With newer generation polyurethane materials, polycarbonate urethanes (PCU) are currently being considered as alternative materials for hard-on-soft bearings.
What is polyurethane fabric?
Polyurethane (PU) is a composite material made of: (1) one or more layers of polymer resins joined by urethane links; and (2) a woven or non-woven textile backing such as polyester, cotton, nylon, or ground leather. This makes the fabric water resistant, light weight and flexible.
Which is better polycarbonate or polyurethane?
Furthermore, there are many important properties of both these materials; polyurethane is important because of its flexibility, low density, durability, etc. and polycarbonate is important because of high impact resistance, low scratch resistance, transparent, can withstand high temperatures, etc.
What are the properties of polyurethane?
Polyurethanes possess high tear resistance along with high tensile properties.
- Resistance to Water, Oil & Grease.
- Electrical Properties.
- Wide Resiliency Range.
- Strong Bonding Properties.
- Performance in Harsh Environments.
- Mold, Mildew & Fungus Resistance.
- Color Ranges.
- Economical Manufacturing Process.
What is the disadvantage of polyurethane?
Short life is a major disadvantage of polyurethane products. Polyurethane has hydroscopic tendencies, i.e. water absorption characteristics. Mattresses made from polyurethane absorb water and gradually disintegrate and lose their quality of support. Polyurethane adhesives and sealants have the same problem.
Is polyurethane toxic to humans?
Polyurethane is the result of the chemical reaction between a polyol and a diisocyanate. Once the chemical reaction of its components has taken place, the result is a polyurethane foam that is completely inert and harmless to humans.
What are the mechanical properties of polyurethane?
Different kinds of polyurethane based coatings have been developed and used in different industries due to their superior properties, such as flexibility at low temperature, high abrasion resistance, high impact and tensile strength, high transparency, excellent gloss, color retention, corrosion protection properties.
