a premature new born is found to be tachypnoeic. On examination there is intercostal recession, nasal flaring and cyanosis. What explains the respiratory distress
the law of La place
what is the law of la place
the tension exterted on a spherical wall of set pressure is inversely proportional to the spheres thickness
boyles law
the volume of a gas at constant temperature varies inversely with the pressure exerted on it.
daltons law
the total pressure of a mixture of gases is equal to the sum of the partial pressures of the individual component gases
henrys law
the amount of gas that is dissolved in a liquid is directly proportional to the partial pressure of that gas above the liquid when the temperature is kept constant.
bohr effect
describes hemoglobin’s lower affinity for oxygen secondary to increases in the partial pressure of carbon dioxide and/or decreased blood pH.
haldane effect
shift in the CO2 dissociation curve caused by oxygenation of Hb.
