## How do you calculate percent saturation of Haemoglobin with oxygen?

CcO2 = oxygen content of end-capillary blood; CvO2 = oxygen content of mixed venous blood; and CaO2 = oxygen content of arterial blood. Oxygen content (ml/dl) is calculated Page 7 as: (1.34 x Hb x SO2) + (0.003 x PO2) where SO2 is percent hemoglobin saturation with oxygen.

## When percentage saturation of Haemoglobin with O2 is plotted against the partial pressure of O2 on a graph the curve obtained is described as?

The relationship between the partial pressure of O2 (PO2) and percentage saturation of the Hb with O2 is graphically illustrated by a curve called oxygen dissociation curve.

## How do you measure hemoglobin saturation?

A pulse oximeter can measure oxygen saturation. It is a noninvasive device placed over a person’s finger. It measures light wavelengths to determine the ratio of the current levels of oxygenated hemoglobin to deoxygenated hemoglobin. The use of pulse oximetry has become a standard of care in medicine.

## Which blood vessel has the highest concentration of glucose after a meal?

hepatic portal veins

pulmonary artery

## How do you describe the sequence of oxygen carbon dioxide and blood flow in your own words?

Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.

## Which lung apex is higher?

The base of the lung is formed by the diaphragmatic surface. It rests on the dome of the diaphragm, and has a concave shape. This concavity is deeper in the right lung, due to the higher position of the right dome overlying the liver.

## How many lobes do you have in your lungs?

The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes.

## Why does the right lung have more lobes?

The right lung is five centimeters shorter than the left lung to accommodate the diaphragm, which rises higher on the right side over the liver; it is also broader. The volume, the total capacity, and the weight of the right lung is greater than that of the left. The right lung is divided into three lobes.

## What does Lingular mean?

The left lung, unlike the right does not have a middle lobe. However the term lingula is used to denote a projection of the upper lobe of the left lung that serves as the homologue. This area of the left lobe – the lingula, means little tongue (in Latin) and is often referred to as the tongue in the lung.

## How much water a day is lost through breathing?

Your body loses water every time you breathe. You lose about 1 cup of water each day, just from breathing!
