Decreased HB Levels In People With Anemia?
Good evening, I want to ask. I have a task for nursing care for animea patients. And based on the data, the Hb tn.D level has dropped from normal to 7.5 but the respiration is normal 22x / min. Can that happen? Even if the oxygen level decreases due to low Hb r n r nThen does high blood pressure always affect the rate of pulse rate / heart rate? R nBased on the data that there are TD patients tn.D 150 / 100mmHg but HR is only 94 and it’s still in the normal category (60-100) why not above 100, so it’s already high. Please explain. Thanks 🙂
Good afternoon, Thank you for the question Anemia is a state of reduced red blood cells or hemoglobin concentration (Hb) below the normal value according to age and sex. Hemoglobin has the function of carrying oxygen to tissues to be used as metabolic material at the cellular level. When oxygen transports to the tissue decreases, there will be a cardiovascular compensation mechanism to overcome oxygen deficiency at the cellular level. The process of delivering oxygen to organs or tissues is influenced by hemodynamic factors in the form of cardiac output, the ability to transport oxygen in the blood, namely Hb concentration, and oxygen extraction, which is the difference in oxygen saturation between arterial and venous blood. When one of the problems, then other factors will increase its work so that oxygen supply can be maintained. When oxygen delivery decreases, venous return will increase as compensation aimed at increasing the amount of oxygen circulating in the blood, resulting in a stroke volume which will also increase. Cardiac output will also increase because cardiac output is influenced by venous return and HR frequency (CO = SVR x HR). Blood pressure rises in response to increased cardiac output (BP = CO x SVR). The whole compensation guarantees sufficient oxygen to the peripheral tissues. In chronic cases the compensatory mechanism is no longer effective so that heart failure can occur due to heavy heart work in a long time, so that the symptoms obtained include rapid breathing. What happens in these patients is an increase in blood pressure due to an increase in cardiac output. Other vital signs are still within normal limits because they are still in a compensated condition. So, hopefully can help you, Dr. Farah
