¿Qué características crees que deben tener los métodos anticonceptivos para ser eficaces en el control de la natalidad?
Tanzania [10]

Answer:

Los métodos anticonceptivos para ser eficaces en el control de la natalidad deben ser seguros para las personas que los utilizan, es decir, no tener efectos adversos, o al menos, la menor cantidad posible. Ser reversibles, es decir, que no generen infertilidad de por vida. Deben ser además fáciles de usar, cómodos y fáciles de conseguir, esto es, económicos. Además deben ser eficientes en su objetivo de evitar la concepción, que es para lo que fueron creados.

Explanation:

La tasa de eficacia de un método anticonceptivo se mide por la cantidad de embarazos que se producen cada 100. Esta parece ser la característica más importante, y si bien es una de las más importantes, hay que tener en cuenta todos los otros factores mencionados, es decir que la gente pueda acceder a ellos, sean cómodos, seguros y a un precio coherente.

Answer: A low pCO2 indicates respiratory alkalosis which may be primary or secondary to a primary metabolic acidosis. Bicarbonate is calculated from measured [H+] and pCO2 values. A high standard [HCO3- ] indicates either primary metabolic alkalosis or a compensatory response to a primary respiratory acidosis.

Explanation: an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis. The higher the minute ventilation, the more exchange and loss of PCO2 will occur inversely.
