Oxygen Delivery & Aerosol Therapy Products
Oxygen Delivery is the most important single ability in animal biology. Oxygen constitutes nearly 50% of the mass of our planet, 21% of the air we breathe, 50% of rock and 89% of water. Yet it took man a surprisingly long time to discover the significance of oxygen in terms of combustion, respiration and animal metabolism. Oxygen is essential for normal respiration in aerobic organisms.
Upon entering the lungs, O2 molecules dissolve in the lipid and aqueous phase of tissues and diffuses across alveolar membranes and into alveolar capillaries. The vast majority of oxygen is bound to haemoglobin and only a small fraction, less than 2% is dissolved in the plasma. Following the transport to various tissues, oxygen diffuses into the cells for metabolism.
Oxygen therapy is the administration of oxygen as a medical intervention, which can be for a variety of purposes in both chronic and acute patient care. Oxygen delivery is essential for cell metabolism, and in turn, tissue oxygenation is essential for all normal physiological functions.
High blood and tissue levels of oxygen can be helpful or damaging, depending on circumstances and oxygen therapy should be used to benefit the patient by increasing the supply of oxygen to the lungs and thereby increasing the availability of oxygen to the body tissues, especially when the patient is suffering from hypoxia and/or hypoxaemia.
