World Health Organization ECG relationship first heart sound is produced just after QRS Complex of ECG duration 0.15 2th that and heart sound this sound is produced by the evaporation associated with the closure of the the loner always just after the end of cooler electrocardiogram introduction electrocardiography is the technique of recording the electrical activity of the heart they according
World Health Organization itself is called and electrocardiogram the first ECG machine was designed by bhai Instagram ECG is composed the normal ECG racing show deflection or wave and is your electric pregnant the wave deflection may be positive or negative above or below the zero line respectively when depolarization Followed by the different region Of the art the ECG can be divided into
World Health Organization three types of recording which consist of complexes or waves interval and segments Basic fact about ECG ECG is a technique for recording the electrical activity of the heart Composed of T wave QRS Complex T wave and u wave if P wave occurring due to Tu hemorrhage Bleeding technically known as ageing or aging insertion and differences the loss of blood or solid as cap from the circulatory system can occur internally where blood leak World Health Organization
from blood vessel inside the body or externally The Other through a natural opening such as the mouth nose air for another hour through operate in the second the complete loss of blood is referred to as aggregation and
aggregation is simple 8 loss typically a healthy person under a load of 10 to 15% of the total blood well volume without serious medical difficulties and blood donation typically takes 8 to 10 of the donor blood
volumePhysiological anatomy of the respiratory system the respiratory system consists of the nose brown tree and long from our clinical point of view is divided into upper and lower respiratory tract Raha Diffusion of gases Respiratory system membrane Oxygen and Carbon dioxide move across the respiratory membrane between the the the pulmonary
capillaries by diffusion diffusion is the movement of molecules from the area of higher concentration to the area of lower concentration by random motion as sun as the lungs filled with air oxygen diffuses from the the only into the blood so the interest lived and finally into the sun on the other hand carbon dioxide diffuse is in the opposite direction from the cell
through the the interest due to the the early before the this version of the PN of gas is the layers of the disparity membrane disparity unit this is used as a unit where gas exchange is take place this is composed of the following structure respiratory membrane pulmonary membrane the membrane of the unit through which exchange of gases take place is collectively called the pulmonary of respiratory membrane layer of respiratory membrane nude and perfect and player and we all were there each layer of the
respiratory membrane is externally in the thickness of the respiratory membrane in some area in as little as 0.2 nanometre with an average of 0.6 NM of oxygen dpn of oxygen from and we’re into pulmonary blood partial pressure of oxygen in the the alveolar is 104 millimetre HG where the Rio 2 of the blood in train the capillary is an average 14 millimetre at g find a
large amount of of O2 has been removed from plant as it passes through the principal tissue the initial pressure difference that cause is oxygen to diffuse into the pulmonary capillary is 104 to 14 is equal to 64 metre HD of at O2 from calories into interest it’ll played partial pressure of otto in the the trial and of the capillary is 95 miniminter HG while in interest retail played it is is 40 and millimetre HG they are far at O2 diffuses from RCM
and of capillary into interstitial fluid transport of O2 in blood transport of respiratory gases between the lungs and body tissue is the main function of blood normally 97 percentage of the oxygen transported from the lungs to the tissue is career in chemical combination with a red oxygen carrying
pigment Mangal login while the remaining 3 % is carried by physically PMT sold in plasma transport of O2 by chlorine globin is an important oxygen carrying pigment when it combines with oxygen the compound formed is called oxyhaemoglobin the amount of O2 their yard in the coloured in
oxyhaemoglobin depend upon the amount of haemoglobin present in the blood equation HB + O2 Arrow HBO 2 the important factors which determine how much oxygen combine with HB when the ohmic login deoxy generated HB is convinced to HBO is the Co2 when the PO to is Hai it band with the hemoglobin but when the Co2 is low or two is released from HP transport adore carry age of Co2 life depend on oxidative process large
amount of Co2 is constitutionally produced in the body under normal resting condition each hundred millimetre of of the oxygenated blood contain or am a lot of Co2 which is carried in the blood in a Farm transport of Co2 dissolved in plasma a small portion of carbon dioxide is transported in the dissolved state to the lungs as we now the pco2 of venous blood is is 45 mm HG and the EC o2o for trial blood is important m m h g for the
amount of Co2 dissolved in the blood at 45 mmhg is 2.7 ml DL on the other hand the amount of Co2 dissolved at 40 mm HG is about 2.4 ml the
difference between 2.7 and 2.4 is only 0.3 ml from the above this causes it is noted that about 0.3 and CO2 is transported in the form of dissolved CO2 by age 100 ml of blood is about 7 % of all CO2 is transported in this form
