Cardiopulmonary resuscitation

The rescue breaths are made by pinching the victim's nose and blowing air mouth-to-mouth. This fills the lungs, which makes the chest to rise up, and increases the pressure into the thoracic cavity. If the victim is a baby, the rescuer would compress the chest with only 2 fingers and would make the ventilations using their own mouth to cover the baby's mouth and nose at the same time. The recommended compression-to-ventilation ratio, for all victims of any age, is 30:2 (a cycle that alternates continually 30 rhythmic chest compressions series and 2 rescue breaths series). Victims of drowning receive an initial series of 2 rescue breaths before that cycle begins. 3607:, revolutionized the field of emergency medical care. Introduced in the early 20th century, this technique involved positioning the patient in a supine position (lying flat on their back) and the performer of the technique kneeling beside or above the patient. The Holger Nielsen technique utilized a manual resuscitator, commonly referred to as the "Holger Nielsen bag," to administer rescue breaths. The performer would place a mask or the bag's mouthpiece over the patient's mouth and nose while manually compressing the bag. This action would deliver a controlled flow of air into the patient's lungs, aiding in oxygenation and facilitating the exchange of gases. 1467:, survival varies even more across the US, from 3% in Omaha to 45% in Seattle in 2001. This study only counted heart rhythms which can respond to defibrillator shocks (tachycardia). A major reason for the variation has been delay in some areas between the call to emergency services and the departure of medics, and then arrival and treatment. Delays were caused by lack of monitoring, and the mismatch between recruiting people as firefighters, though most emergency calls they are assigned to are medical, so staff resisted and delayed on the medical calls. Building codes have cut the number of fires, but staff still think of themselves as firefighters. 827:

the patient's jewels or piercings, but it should be avoided placing the patches of the defibrillator directly on top of them. The patches with electrodes are put on the positions that appear at the right. In very small bodies: children between 1 and 8 years, and, in general, similar bodies up to 25 kg approximately, it is recommended the use of children's size patches with reduced electric doses. If that is not possible, sizes and doses for adults would be used, and, if the patches were too big, one would be placed on the chest and the other on the back (no matter which of them).

Another study, of advanced cancer patients, found the same 10% survival mentioned above. A study of Swedish patients in 2007–2015 with ECG monitors found 40% survived at least 30 days after CPR at ages 70–79, 29% at ages 80–89, and 27% above age 90.

1349:(ROSC), all organs can be considered for donation. If the patient does not achieve ROSC, and CPR continues until an operating room is available, the kidneys and liver can still be considered for donation. 1,000 organs per year in the US are transplanted from patients who had CPR. Donations can be taken from 40% of patients who have ROSC and later become brain dead. Up to 8 organs can be taken from each donor, and an average of 3 organs are taken from each patient who donates organs. 38: 727: 12523: 11092: 574: 483: 11104: 735: 438: 107: 287: 495: 3355:

One study found that members of the public having received CPR training in the past lack the skills and confidence needed to save lives.

Peter Nagele of Washington University in St. Louis. A study published Oct. 6 in the Journal of the American Medical Association found that bystanders who applied hands-only CPR were able to boost survival to 34% from 18% for those who got conventional CPR or none at all. In addition, the percentage of people willing to provide CPR rose from 28% in 2005 to 40% in 2009.

944:, where manual compressions are difficult, and they allow ambulance workers to be strapped in safely rather than standing over a patient in a speeding vehicle. However the disadvantages are cost to purchase, time to train emergency personnel to use them, interruption to CPR to implement, potential for incorrect application and the need for multiple device sizes. 393:(AHA) guidelines of 100–120 compressions per minute, this can cause a net decrease in venous return of blood, for what is required, to fill the heart. For example, if a compression rate of above 120 compressions per minute is used consistently throughout the entire CPR process, this error could adversely affect survival rates and outcomes for the victim. 1456:(CARES). CARES reports CPR results from a catchment area of 115 million people, including 23 state-wide registries, and individual communities in 18 other states as of 2019. CARES data show that in health care facilities and nursing homes where AEDs are available and used, survival rates are double the average survival found in nursing homes overall. 7631:"Practice guideline update recommendations summary: Disorders of consciousness: Report of the Guideline Development, Dissemination, and Implementation Subcommittee of the American Academy of Neurology; the American Congress of Rehabilitation Medicine; and the National Institute on Disability, Independent Living, and Rehabilitation Research" 3602:
