Excerpts from restart.com:
Starting next week, the Rockford Fire Department is implementing a new policy aimed at improving outcomes for victims of sudden cardiac arrest. Dispatchers will now ask two critical questions when receiving emergency calls: Is the person conscious? Is their breathing normal?
If the answer to both questions is no, the dispatcher will immediately instruct the caller to take action. Instead of asking whether they're comfortable performing CPR, the caller will be guided step-by-step through administering chest compressions. The goal is to ensure that the victim receives around 100 compressions per minute, which can significantly increase their chances of survival.
This initiative is being rolled out by Rockford's 42 dispatchers, who will play a pivotal role in guiding callers through these life-saving steps. Their efforts are part of a broader strategy to boost the city's out-of-hospital cardiac arrest survival rate, which stood at 46.2% in 2015. Chief Derek Bergsten and Dr. Jane Pearson, an emergency medicine specialist from OSF Saint Anthony Medical Center, unveiled the program at the Rockford Fire Department headquarters. They aim to reach a 50% survival rate within the next year.
“In moments of crisis, people often feel overwhelmed and unsure of what to do,†explained Chief Bergsten. “By providing clear instructions and pacing them through the process, we hope to empower callers to act quickly and confidently.†Dr. Pearson, who trains dispatchers, noted that the national average for out-of-hospital cardiac arrest survival hovers between 20-30%. In contrast, King County in Washington state, home to Seattle, boasts one of the highest rates, at over 62%.
Cardiac arrest occurs when the heart suddenly stops functioning, and each year, more than 420,000 such incidents occur across the United States. Since late 2014, Rockford has seen steady improvement in its survival statistics, largely due to a renewed focus on high-quality chest compressions. Firefighters responding to emergencies are now extending their on-scene CPR efforts to approximately 20 minutes—nearly triple the previous average of six minutes—before transporting patients to hospitals.
“Our success isn't just about numbers,†emphasized Dr. Pearson. “It's about ensuring that survivors return to full functionality. That means being able to live independently without assistance.†She credited the collaborative approach among dispatchers, emergency medical technicians (EMTs), and hospitals as key to achieving these results. “When everyone works together, we create a seamless system where every link contributes to saving lives.â€
Introduction to GENT direct expansion wshp
GENT direct expansion wshp is a Direct Expansion Air Conditioning that uses natural water sources at normal temperature, such as surface runoff, groundwater, etc., and refrigerant as the medium to achieve indoor cooling and heating through direct heat exchange between indoor air and water.
How the unit works?
After the unit uses a water pump to take water from the preset water intake point, the direct-expansion Water Source Heat Pump uses the fan, refrigerant and compressor in the unit to blow air directly into the room to achieve indoor space cooling and heating. Therefore, this unit is a direct expansion device that can achieve its purpose without the assistance of indoor terminals. The water after heat exchange is discharged back to the water intake point by the water pump, and is not continuously circulated in the direct expansion water source unit.
From this, it can be seen that the water source dx Air Conditioning is actually a deformation of the water source heat pump. The water source used by water source heat pump is also the natural water at normal temperature, and the water involved in the heat exchange does not circulate continuously within the unit.
The difference between the two units lies in the different output forms. The dx water source heat pump directly produces cold air or hot air, while the water source heat pump produces cold water or hot water. If indoor cooling and heating are to be achieved, the assistance of indoor terminals is also required.
Therefore, the special feature of GENT water source direct expansion ac system is that it does not require the installation of indoor terminals. This can effectively reduce the initial equipment investment cost and installation difficulty.
What are the restrictions of using the unit?
The unit needs to be close to the water source.
Because the unit needs to continuously take in water and drain water during operation, the unit should be installed close to the water source. If the unit is far away from the water source, the long water source transportation distance will increase the cost of laying pipes and cause a certain degree of heat loss, which will affect the operation effect of the unit. Therefore, users who intend to use this unit need to ensure that there is a sufficient amount of corresponding water source around the preset use site for the unit to use.
In summary, this unit has both advantages and disadvantages. This unit does not require the installation of additional indoor terminals, but it also has the common pain point of water source heat pump, that is, the unit needs to be installed close to the water source. If there is no available water source around the installation site of the unit, the high-efficiency and energy-saving characteristics of the unit will not be brought into play, and even the unit will not be able to operate normally, which greatly limits the installation range of the unit.
Then, users who need to control the initial equipment investment cost and have available water sources around are very suitable for this unit. This unit can save you costs to the maximum extent while ensuring the heating and cooling effects. Interested users are welcome to communicate with us for consultation.
