opiod analgesics

opiods are substances that act on opiod receptors and produce morphine like effects.these are generally used to relieve pain.the drugs are derived from opium alkaloid.these drugs mainly includes synthetic and semisynthetic drugs such as hydrocodon,oxycodon and fentanyl.antagonist drugs such as naloxone. besides used as pain reliever these are used for treating cough also                                       medical uses: pain,acute pain,chronic non cancer pain etc.                                                                      other:cough,diarrhoea and shortness of breadth                                                                                 adverse effects:nausea and vomitting,drowsiness,itching,constipation,respiratory depression,opiod induced hyperalgesia.                                                                                                                                    

                                   

DOP/PAO Test

What is a DOP/PAO Test ?

DOP/PAO testing is a very quick process that tests the integrity of the HEPA (High Efficiency Particulate Air) filter using DOP or PAO solutions in their operational conditions.

These solutions generate a gas type smoke and then generate gas particles that will be greater than .03 microns. The test will certify the HEPA filter is fully functioning and there is no leakage or damage.

Meaning of DOP?

DOP (Dispersed Oil Particulate) is a dispersed aerosol used to test the integrity of HEPA filters.

Meaning of PAO?

PAO (Poly Alpha Olefin) is a non-carcinogen liquid which is a most common replacement for DOP.                                                                                                                                              When to do DOP test

Any equipment that has a HEPA filter should be tested every time the equipment is moved or going to be used on a new project (every four weeks if on same project). For the best results testing should be done on-site to ensure that the units have not been damaged due to transportation or daily activities at the work site.

 this is very useful  for clinliness.

Also rough handling of the equipment can cause the filter seals to become loose from around the HEPA filter therefore causing leakage and making them unsafe for workers who are counting on them while working in hazardous conditions.

What is a HEPA Filter?

HEPA filters are composed of usually fiberglass fibers randomly arranged. To qualify as HEPA the air filter must remove at least 99.97% of all airborne particles greater than 0.3 micrometers in diameter from the air that passes through it.

what is congestive heart failure?

congestive heart failure: CHF occurs when the heart is unable to pump suffieciently to maintain blood flow to meet the body's needs.
