Answer:
The best answer to the question: Recovery from a severe metabolic acidosis is most dependent on which of the following? would be, D: Arterial pH.
Explanation:
When a person reaches such a severe situation, as having metabolic acidosis, then it means that his body systems are not being able to use the mechanisms to restore the normal acid-base balance within it. Normally, a person needs to have an acid-base balance of 7.35 to 7.45. Drops below or above these numbers will result in acidosis or alkalosis and in severe problems. The way that the body can tell if there is something going on with the pH levels in the blood is through a series of chemoreceptors, especially in the neck, that constantly measures the amount of CO2 molecules in the blood and especially, the pH (acidity or alkalinity) given by the excessive presence, or absence, of acids in the blood. There is another ration that is important for the body, and it is the presence of bicarbonate ions, which will help balance out the amount of H+ ions produced by normal cell function, or increased cell function. In metabolic acidosis, the amount of H+ vs. bicarbonate ions is immense, H+ winning by far over bicarnonate, and a series of steps are taken by the body to restore the 20:1 ratio, and especially return the pH to its normal range. All mechanisms point towards that one measure: pH. Once the level of pH has been reached, we can tell a person is finally coming out of metabolic, or recovering from, metabolic acidosis.
um I suggest call the ambulance and parents right away...
Prior studies have not included trauma and postoperative patients, but it has been demonstrated that therapeutic hypothermia (TH) and targeted temperature management (TTM) improve outcomes in cardiac arrest survivors. We investigated the safety of TH/TTM in surgical and trauma patients. An adult patient who presented with a cardiac or traumatic arrest in the postoperative period and had been treated with either TH or TTM had a Glasgow Coma Scale of 8 when the patient was reviewed in a retrospective cohort study at a single level I trauma center. A patient's neurological recovery is deemed positive if they were released after obeying orders.
32 cardiac arrest patients in all, 14 of whom received TH treatment and 18 of whom received TTM treatment, with target temperatures of 33°C and 36°C, respectively, were included in the study. With 26 (81%) men, the cohort had a mean age of 60 13. There were 14 postoperative patients and 18 trauma patients. Pneumonia (13%), sepsis (6%), bleeding that required transfusion (22%), arrhythmias (6%), and seizures (9%), which are similar to earlier reported series, were among the complications. All survivors had good neurological recovery, and the overall survival rate (n = 13) to discharge was 41%. Patients who had previously been excluded from TH/TTM studies due to traumatic arrest and postoperative cardiac arrest appear to have an acceptable incidence of problems compared to conventional TH/TTM patients.
What is cardiac arrest ?
When the heart unexpectedly and unexpectedly stops pumping, cardiac arrest happens. If this occurs, blood supply to the brain and other important organs is interrupted. Certain arrhythmias that stop the heart from pumping blood result in cardiac arrests. A medical emergency is cardiac arrest.
