Facts Behind Hidden Facts and Figures of Covid19

Covid-19 Pandemic is showing its aggression on daily basis, more victims more casualties more death and more fear globally. Spread rate is multiply every single day, even death tolls are increased but some of the nations have to hide the actual figures of deceased persons, the purpose of this writing is to identify why that tool as a major indicator is not very correctly mentioned around the globe.

There may be many reasons for this, what I have observed are as follows.

Economic Crises:

The current war is just to strength economically and unfortunately this pandemic disease starts from china and first reach to the strong countries such as USA, UK, Spain, and European Countries, they have strong health system but this crisis has locked down them and halt for weeks, those who were having strong economic growth their systems are also shivering and it’s Shrinked.

They have huge number of death tolls, to control and stable economic crises and to decrease the fear of corona from people they show a smaller number of death and increase is number of recovered people but do you think it’s justified to hide the actual number? Hiding facts are never be so cool and ethically considered.

Health Care System:

Many of the Hospitals and Health care system are not trained nor built to handle sick and coronoid patients, due to fear of spread into their system and affect others, those who can accommodate sick patients they have less resources because they need isolation area to separate one from another which require huge place, temporary hospitals built, town halls and other areas convert into hospital setup, which is not enough to cater the big numbers.

Personal Protective Equipment’s PPE:

Health care workers have a biggest issue to have PPE, Mask, and Sanitizer, glasses, isolation kit and other PPE. The production is the biggest issue, each country needs them, the demand is very high against the productivity, most of the countries, flight operations are also halt to minimize the spread, this PPE issue also a fear for Doctors, Nurses, and other paramedics to work in the health system, as this deadly disease already affect healthcare workers and eaten many life’s of the healthcare heroes. We need to keep supply the PPE to our health care heroes so they can fight against this pandemic disease.

But question revolving around my mind is if there are patients with positive covid19 and isolation is not yet completed, those patients who are at high risk can get the disease from the community.

According to facts and figure which show the danger is not yet complete, it’s still in our community. If we take it seriously we will win otherwise we had to lose HOPE.

Medical Air Systems for Healthcare Facilities

Medical air systems are a vital element of all hospitals and most other healthcare facilities. The engineer must consider expense, capacity, physical size and weight, space limitations, and mechanical and electrical utility availability in choosing a system for a particular project. It is important to coordinate the equipment selections with the owner as well as other engineering and architectural disciplines.

The first priority is life safety. Medical air is used for respiratory therapy and calibration of medical devices for respiratory application. Providing clean, oil-free air is mandatory. The medical air system should not be used to supply air for any other purpose (e.g., hospital laboratory use) because of the opportunities for contamination of the distribution system. If a patient inhales medical air contaminated by oil from a defunct compressor or nitrogen from a brazing purge, the consequences could be irreversible. In addition, a utility or pipeline shutdown must be coordinated with the hospital staff to prevent an accidental service termination while patients are connected to the system. Engineers should be aware of the requirements before designing any medical gas system.

Distribution Systems

Medical compressed air systems must be designed to prevent the introduction of contaminants or liquid into the pipeline. Medical air systems must:

• be supplied from cylinders, bulk containers, or medical air compressor sources; or reconstituted from oxygen USP and oil-free, dry nitrogen

• meet requirements of the medical air

• contain no detectable liquid hydrocarbons

• contain fewer than 25 ppm gaseous hydrocarbons

• contain 5 mg/m3 or less of permanent particulates sized 1 micron or larger at normal atmospheric pressure.

In a typical fully functioning healthcare facility, the medical air is supplied by a high-pressure cylinder manifold system or a medical air compressor system. Manifold distribution systems typically are used in facilities that have very little demand for medical air. Medical air compressor plants typically are for larger facilities.

Existing facilities may choose to upgrade their equipment and associated pipeline or add medical air plants as the facility expands. When selecting a piece of equipment for a new facility, the possibility of future expansion should be considered. To allow for future growth, it is good practice to be conservative in sizing a system.

Duplex Medical Air Compressor Source Systems

An engineer usually has more options available when designing for a new facility than for a renovation or replacement project. Electrical and mechanical utilities can be more easily calculated, and chilled water, ventilation, and electrical services can be sized and adequately located. The ideal schematic design contains a well-ventilated, easily accessible mechanical room dedicated to medical gas equipment.

In selecting a medical air compressor for an upgrade, the engineer may have some trouble due to mechanical utility inefficiencies (e.g., poor chilled water quality, a poorly ventilated mechanical space). The local electric utility may not support the pump arrangement, or poor equipment access may require breakdown of equipment parts at a significant cost increase. It is imperative to conduct thorough surveys of the surrounding mechanical space and utilities before determining the best type of compressor for the project.

It is a good idea to select more than one type of compressor at the schematic design phase. You should develop a master plan that shows existing demand and estimated spare capacity. The owner may want to obtain a cost estimate before making a final decision.

Types of Compressors

All medical air compressors must be able to deliver compressed air that does not contain oil. This article specifically deals with medical air systems for Level 1 hospitals.

There are three acceptable types:

• Oil-free compressors: These reciprocating compressors have no oil film on surfaces exposed to air being compressed. They do have oil in the machine and require separation of the oil-containing section from the compression chamber by at least two seals. The interconnecting shaft and seals must be visible without disassembling the compressor.

• Oilless compressors: These reciprocating or rotary-scroll compressors do not have oil in the machine. Lubrication is limited to seal bearings.

• Liquid ring pump: These rotary air compressor pumps have a water seal. It is recommended that a heat exchanger be utilized to conserve seal water.

Medical air compressor plants should be sized to serve peak calculated demand when the largest compressor is out of service. In an efficient design of a larger system (i.e., three pumps or more), each compressor is sized to handle an equal percentage of the peak demand and create redundancy. There never should be fewer than two compressors.

Accessory Equipment

Several pieces of mechanical equipment accompany the medical air compressor system:

• Intake: The compressor’s air intake must be located outdoors, above roof level, and at least 10 ft from any door, window, other intake, or other opening. Intakes must be turned down, screened, and equipped with intake filter mufflers. These filters remove large amounts of particulates (microscopic particles of solid or liquid matter suspended in the air) and contaminants at the compressor inlet.

• Air receiver: The role of the air receiver is to store air and balance pressure variations. It must have a full-size bypass as well as a manual and automatic drain to remove any collected condensate. It must meet American Society of Mechanical Engineers ( https://asme.org ) Section 8 boiler and pressure vessel construction standards. The receiver is sized based on system demand, compressor size, and compressor running times.

• Compressed air dryer: The dryer is used to remove water vapor from the air stream. At a minimum, it must be a duplex system valved to allow one unit to be serviced. Dryers should be of the desiccant twin-tower type, sized for 100% of calculated load at design conditions. They should be rated for 32°F (0°C).

• Duplex final filters: These should be rated for 100% system capacity, with a minimum of 98% efficiency at 1 micron or greater. The filter must be equipped with a visual indicator showing the remaining filter element life.

• Medical air regulators: Regulators control the pressure of the air system. They should be sized for 100% of the system’s peak calculated demand at design conditions. Pressure regulators should be set to provide the most distant outlet with 50-psig medical air.

• Alarm sensors: A medical air compressor must have alarm sensors located nearby where they can be continuously monitored by hospital personnel. Typical alarms are for high pressure, low pressure, and other trouble (e.g., lead/lag pump operation, high temperature, high dew point, carbon monoxide). Additional alarm signals can be added depending on the type of compressor and the owner’s preference.

• Anti-vibration mountings: These should be provided for the compressors, receiver, and dryers, as required by the manufacturer.

Piping

Medical air piping is sized according to the calculated flow rate in cubic feet per minute (cfm). Compressed air piping is constructed of brazed type-L copper prepared for oxygen service. The piping must be pitched toward the central plant, have drains at low points and it must be valved and identified.

Epidemic Covid-19 (Corona) Vs Humanity

My condolence to those who lose their love once, also with them who lost their jobs in this pandemic situation, today I feel I am living in a country where all are one hand weather to help each other or together to fight against all the disasters situation.

We are UNITED

We were United and

We will be

Global economic crises affected the under developing and 3rd world country, their foreign employees are losing their jobs, families and lives are affected but nobody care, think about them, supports or empathized with them it seems we all living life of animals like in jungle where nobody knows each other, powerful trying to eat helpless if fortunately you survived you have to swim all alone just to be alive

so many citizens of my country (Pakistan) lost jobs, and now waited for governmental support to bring them back, all of them are loyal citizens, many choose to work for their own country besides having good monetary compensation advantage and other picked as well but they choose to serve their own country but what they got hunger, poverty corruption to get job in their own country and those who left for their future after earning some of them compare their abroad earning with native country, let’s not discuss, no matter the purpose behind their leaving. The prime minister of Pakistan to come back and serve their own country and he is still trying to help them and it’s a good gesture.

Corona battle against mankind spread its dark clouds, change a day into night, we look towards almighty ALLAH. We see rising of sun and we get back into our life with this hope that the setting sun bring up a good news of ending corona

WHO (World Health Organization) and so many Health Organization at International, National, Provincial District and area level take the responsibility to educate people so that they maintain social distancing, hand washing and avoiding unnecessary travel, work and routine activities.

one after one another country affected with corona, lock down and even curfew become the solution to control the disease because nobody has medical solution for this, till today its affected China, Spain, United Kingdom, Italy and currently on peak at United States with highest death tolls, poor countries such as South Asian regions and African countries, their peoples don’t have even basics necessaries of living, no proper water supply, food supply and health facilities available

I live in Karachi Pakistan, where we have huge population in Karachi, no proper water supply, people’s basic income is very low even they cannot afford the lock down. WHO hand washing guideline cannot work, because they don’t have water to drink, how it’s possible to social distance, in a single room where 7-10 family members are living in a single room how can we make a distance of 1-3 meter, peoples are living in temporary shelters for social distancing

The reason is not Pakistan, the reason is rest of the rich countries their lobbies and political science and so called policies; make poor counties more unstable and poorer moreover make them living below the line of poverty and we all know who are responsible for that.

May ALLAH forgive all the sins of the mankind, protect sick and aged population that are vulnerable. In this battle young doctors, nurses, hospital staff, social volunteers, housekeeping staff, rescue teams, ambulance staff, and so many which might not in my words, off course in my memory but in my prayers lost their lives or their love ones, they can’t stay home, they were in the field to defeat corona.

Mankind always remember this 3rd world war which killed so many but our Nurses, Doctors and Paramedical take charge to stop it. We salute them and I wish medical solution get successful cure so by the grace of Almighty ALLAH all other remaining are cure
