Problems with the lungs prevent the body and organs from getting enough oxygen to the cells and functioning properly. Blood oxygen levels are low (hypoxemia). Oxygen deprivation can be life threatening. If your oxygen level drops below 88%, your healthcare provider will prescribe oxygen therapy. Pulse oximeter: This tiny device easily attaches to your finger, toe, or earlobe. Sensors in the device send light rays through the skin to measure oxygen levels in capillaries (small blood vessels). Many providers run this test regularly for each booking. You can also purchase a pulse oximeter (pulse oximeter) at a drugstore and use it at home. Arterial blood gas test: This test uses a blood sample taken from an artery to measure the levels of oxygen and carbon dioxide in the blood. This test is the most accurate method of determining lung function. Pulmonary function test: Pulmonary function tests, such as spirometry, measure how well a person inhales and exhales air. Some tests also measure the ability of the lungs to deliver oxygen to cells. Oxygen therapy can be done virtually anywhere. There are small oxygen systems that can be carried anywhere (portable oxygen). Oxygen occurs in gaseous or liquid form. Oxygen systems can be large and stationary for home use, or they can be small and portable. The bottle has a regulator that controls the flow of oxygen. Oxygen conserving devices deliver oxygen when you breathe in and stop the flow of oxygen when you breathe out. These tanks eventually run out of oxygen. A gauge indicates the oxygen content of the tank. Once the tank is empty, it is replaced by an oxygenator. You should always have a spare oxygen cylinder on hand. Releasing oxygen turns the liquid into a breathing gas. Small containers are portable for use outside the home. Oxygen concentrator: This electrical or battery powered device extracts air from the room. It then separates and compresses the oxygen from the air while removing the nitrogen. Inhale clean air. With a concentrator you will never run out of oxygen. A concentrator is the most portable system. Many models are also Federal Aviation Administration (FAA) approved, so you can bring them on the plane. Never smoke near oxygen cylinders. Also, when using oxygen, stay at least 5 feet away from flames such as gas stoves, candles, fireplaces, or fireplaces. Secure the oxygen cylinder upright on a stand or fixed object. Do not roll the oxygen cylinder. A falling or rolling tank can burst, creating pressure that can cause the tank to explode. This allows the small amount of oxygen that the tank continually releases to be released into the air instead of accumulating and becoming a fire hazard. Keep him at least 2.50 m from heat-producing devices such as heaters and appliances. Do not use flammable materials such as aerosol sprays, detergents, and oil (petroleum) products near oxygen cylinders. Choose cotton clothing and bedding over wool, nylon, and synthetic materials that can create static sparks. Make sure your smoke detector is working.
