Which imbalance results when systemic arterial blood co2 levels raise to abnormal values?

Which condition may result in respiratory alkalosis?

Any lung disease that leads to shortness of breath can also cause respiratory alkalosis (such as pulmonary embolism and asthma).

Which of the following is a common cause of metabolic alkalosis?

Metabolic alkalosis is primary increase in bicarbonate (HCO3) with or without compensatory increase in carbon dioxide partial pressure (Pco2); pH may be high or nearly normal. Common causes include prolonged vomiting, hypovolemia, diuretic use, and hypokalemia.

Which of the following is the most common cause of respiratory acidosis?

Common causes of respiratory acidosis

Respiratory acidosis is usually caused by a lung disease or condition that affects normal breathing or impairs the lungs’ ability to remove CO2. Some common causes of the chronic form are: asthma. chronic obstructive pulmonary disease (COPD)

What is the main factor that determines water loss?

Various environmental factors such as temperature, humidity, radiation, and atmospheric pressure affect mainly sweating and urinary water loss, while physical exercise affects, in addition, increased respiratory water loss from the increased expiratory volume and frequency of breathing.

What are the signs of acidosis or alkalosis?

Symptoms of alkalosis can include any of the following:

  • Confusion (can progress to stupor or coma)
  • Hand tremor.
  • Lightheadedness.
  • Muscle twitching.
  • Nausea, vomiting.
  • Numbness or tingling in the face, hands, or feet.
  • Prolonged muscle spasms (tetany)

What happens if your blood is too acidic?

If an increase in acid overwhelms the body’s acid-base control systems, the blood will become acidic. As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing (respiratory compensation).

How do you correct metabolic alkalosis?

Metabolic alkalosis is treated by replacing water and mineral salts such as sodium and potassium (electrolytes) and correcting the cause. Respiratory alkalosis is treated by correcting the cause.

How do I know if I have metabolic alkalosis?

Metabolic alkalosis is diagnosed by measuring serum electrolytes and arterial blood gases. If the etiology of metabolic alkalosis is not clear from the clinical history and physical examination, including drug use and the presence of hypertension, then a urine chloride ion concentration can be obtained.

What is the most common cause of metabolic alkalosis quizlet?

This occurs between RBC and blood plasma as the blood level of carbon dioxide increases or decreases. This is the most abundant mineral in the body. This imbalance results when systemic arterial blood CO2 levels raise to abnormal values. This is the most common cause of metabolic alkalosis.

What causes high PCO2 levels?

The most common cause of increased PCO2 is an absolute decrease in ventilation. Increased CO2 production without increased ventilation, such as a patient with sepsis, can also cause respiratory acidosis. Patients who have increased physiological dead space (eg, emphysema) will have decreased effective ventilation.

How do you reverse respiratory acidosis?


  1. Bronchodilator medicines and corticosteroids to reverse some types of airway obstruction.
  2. Noninvasive positive-pressure ventilation (sometimes called CPAP or BiPAP) or a breathing machine, if needed.
  3. Oxygen if the blood oxygen level is low.
  4. Treatment to stop smoking.

How does the body compensate for an increase in CO2?

In addition, the body uses other specific mechanisms to compensate for the excess carbon dioxide. Breathing rate and breathing volume increase, the blood pressure increases, the heart rate increases, and kidney bicarbonate production ( in order to buffer the effects of blood acidosis), occur.

What is the major hormone that regulates water loss?

The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys.

Which hormone most affects the osmolarity of blood?

Neurons containing antidiuretic hormone (ADH, vasopressin) (Table 30.2) are influenced primarily by fluctuations in the osmolarity of the blood. The relative concentration of sodium chloride in blood plasma is normally about 300 mOsm. This osmolarity is largely a function of how much water is retained within the body.

Which of the following occurs between RBC and blood plasma as the blood level of carbon dioxide increases or decreases?

Fluid and Electrolyte Balance
