Assessing and monitoring blood gas levels is the most accurate means to identify a state of respiratory compromise in patients. ABG testing does however require an arterial blood sample, which is more invasive and uncomfortable for patients than a pulse oximetry reading that uses a reading based on light and color.
Typically, infections cause 75% or more of the exacerbations; bacteria can roughly be found in 25% of cases, viruses in another 25%, and both viruses and bacteria in another 25%. Airway inflammation is increased during the exacerbation resulting in increased hyperinflation, reduced expiratory air flow and decreased gas exchange. [1] [2]
Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia ; a rise in arterial carbon dioxide levels is called hypercapnia .
Any deviation from this value is considered a V/Q mismatch. Maintenance of the V/Q ratio is crucial for preservation of effective pulmonary gas exchange and maintenance of oxygenation levels. A mismatch can contribute to hypoxemia and often signifies the presence or worsening of an underlying pulmonary condition. [3]
This leads to impaired gas exchange, most often leading to shortness of breath which can progress to hypoxemia and respiratory failure. Pulmonary edema has multiple causes and is traditionally classified as cardiogenic (caused by the heart) or noncardiogenic (all other types not caused by the heart). [2] [3]
Because gas exchange is impaired, signs of low blood oxygen saturation, such as low concentrations of oxygen in arterial blood gas and cyanosis (bluish color of the skin and mucous membranes) are commonly associated. [6] Dyspnea (painful breathing or difficulty breathing) is commonly seen, [6] and tolerance for exercise may be lowered. [7]
France established buprenorphine’s effectiveness years ago. Between 1995 and 1999, the country reduced overdose deaths by 79 percent as buprenorphine use in treatment became widely accepted. The medication, along with methadone treatment and needle exchange initiatives, also helped cut in half the HIV rate among intravenous drug users.
This plan is specific to each patient and focuses on achievable outcomes. Actions involved in a nursing care plan include monitoring the patient for signs of change or improvement, directly caring for the patient or performing necessary medical tasks, educating and instructing the patient about further health management, and referring or ...
