It is a basic need; alkaline; dry gas and flammable.
Oxygen
It is the act of breathing; inhalation(inspiration), exhalation(expiration).
Movement if air insie ad iutside the lungs.
Ventilation
It is the passive movement of oxygen between the air in the alveoli and the capillaries.
Diffusion
It is the movement of the oxygenated blood to the lung tissue.
Perfusion
It measures the oxygen saturation (O2 concentration;amt.of oxygenated blood n the arterial blood).
Pulse oximetry
What is the normal O2 saturation?
95-100%
<70 is life threatening
It is a painless but tiring procedure that measures the lung volume and capacity. Used in asmathic patient.
Pulmonary function test
In lung scan, what solution is inserted through IV and recorded as it circulates through the lungs.
Radioisotope- tagged albumin
It is used to assess the pulmonary vascular system. Used ti assess pulmonary emboli.
Pulmonary angiography
It allows direct visualizationof the larynx and bronchi. Tissue samples may also be taken.
Laryngoscopy and bronchoscopy.
In laryngoscopy and bronchoscopy, before the fiberoptic scope is inserted, a local anesthetic is sprayed on the pharynx preventing what condition?
Gagging
What are the common medication used during oxygenation?
Bronchodilators- reduses bronchospasms
Expectorants- liquefy mucus, making it esier to expectorate
Cough suppressants- are used when constant coughing interrupts sleep.
What is the position of the patient during oxygenation?
Semi-fowler’s or high fowler’s position.
Part of the O2 tank that adds water vapor to the air in the form of cool mist, to prevent drying and irritation of mucuos membrane and loosen secretions.
Humudifier
