Arterial blood gases, ABGs, Discovery Health:"Arterial blood gases, called ABGs, are a series of blood measurements that are ordered as a single test. This test is used mainly to check lung function and acid levels in the body." ******************************************************
Blood Gasses, The Doctor's Doctor:"A blood gas is exactly that...it measures the dissolved gases in your bloodstream. This provides one of the best measurements of what is known as the acid-base balance. The body is an active chemical reaction, requiring a precise balance of the acids and bases, a measurement known as pH. The normal pH is 7.40. There are four parameters which are measured:
Oxygen (O2)
Carbon Dioxide (CO2)
Bicarbonate (HCO3-)
pH" ******************************************************
Arterial Blood Gases (ABG's), Emergency Clinical Guide:"Normal arterial pH is 7.40. pH is one of the most tightly regulated values in the body - homeostaic mechanisms are in place that maintain the pH to within very tight tolerances. Any variation of more than 0.02 in either direction is a sign of poor control. Blood is considered acidic at values below 7.38 and alkaline at values above 7.42.
The primary processes involved are acidosis and alkalosis - meaning that something is happening to cause the condition in the blood of acidemia or alkalemia. They love to pimp you on the difference between acidosis and acidemia - remember that the first is a process and the second is the resulting condition." ******************************************************
Arterial Blood Gases (ABGs), Lab Tests Onine UK:"Why get tested? To determine if you have an imbalance in the amount of oxygen gas (O2) or carbon dioxide gas (CO2) in your blood or an acid-base imbalance (i.e. if your blood is too acidic/ alkaline), which may indicate a respiratory (lung/breathing), metabolic, or kidney disorder." ******************************************************
Arterial blood gas, Lungsonline.com:"Arterial blood gas levels can tell your doctor many things about your lungs. More commonly referred to as ABG's, arterial blood gasses are normally obtained to see the oxygen, carbon dioxide, pH, and bicarbonate level in the blood.
How are blood gas samples obtained?
Blood Gases are normally obtained from an artery because arterial blood will give your doctor the best idea of how well your lungs are working. The blood sample is obtained in much the same way that a standard blood sample is taken. The only difference is that most blood samples are taken from a vein and this sample will come from an artery. The amount of discomfort should be about the same as any blood sample that you have given in the past. This blood is usually drawn from your wrist or the inside of your arm just opposite." ******************************************************
Blood gases, Medline Plus:"The test is performed by collecting a sample of blood from an artery. Using a small needle, the sample may be collected from the radial artery in the wrist, the femoral artery in the groin, or the brachial artery in the arm. Before blood is drawn, the circulation to the hand may be tested (if the wrist is the site). After the blood is drawn, pressure must be applied to the puncture site for at least 5 minutes to completely stop the bleeding. The test must be sent to the laboratory for analysis immediately, or the accuracy of the results cannot be guaranteed." ******************************************************
Introduction, Mad Scientist Software's Blood Gases tutorial software:"Two p.m., Bayside Community Hospital, the emergency room. A 29-year old female is complaining of chest pain and shortness of breath. The intern tells you her PaO2 is normal. Anxiety and hyperventilation, he says. Entering the room, you see a hyperventilating young lady with a cast on her right leg and a pack of cigarettes sticking out of her purse. On the chart, you see “Meds: BCP.”
A quick calculation of the Aa gradient tells you that this patient’s “normal” oxygen is not normal at all — it’s depressed for her level of hyperventilation. Suspecting pulmonary embolism, you order a lung scan." ******************************************************
arterial blood gasses, Patient UK:"arterial blood gasses - also known as or related to abg - arterial blood gas analysis, abg., arterial gases, bg - blood gases, arterial blood gases, arterial blood gases reference intervals." ******************************************************
Arterial Blood Gas, Wikipedia:"Arterial blood gas measurement is a blood test that is performed to determine the concentration of oxygen, carbon dioxide and bicarbonate, as well as the pH, in the blood. Its main use is in pulmonology, as many lung diseases feature poor gas exchange, but it is also used in nephrology (kidney diseases) and electrolyte disturbances. As its name implies, the sample is taken from an artery, which is more uncomfortable and difficult than venipuncture."

Management of Airway Emergencies, AARC Clinical Practice Guideline:"Management of airway emergencies (MAE) for the purpose of this guideline encompasses all care necessary to deal with sudden and often life-threatening events affecting natural and artificial airways and involves the identification, assessment, and treatment of patients in danger of losing or not being able to maintain an adequate airway, including the newborn. This includes (1) identification of the causes of airway emergencies; (2) management of airway emergencies prior to tracheal intubation; (3) use of adjunctive equipment and special techniques for establishing, maintaining, and monitoring effective ventilation; (4) translaryngeal tracheal intubation, including nasal and oral tracheal intubation; (5) transtracheal catheter ventilation, (6) percutaneous dilational cricothyrotomy, and; (7) surgical cricothyrotomy."
