Hypoxia and Hypoxemia – Nursing is a profession within the healthcare sector focused on the care of individuals, families, and communities so they may attain, maintain, or recover optimal health and quality of life. Nurses may be differentiated from other healthcare providers by their approach to patient care, training, and scope of practice. Nurses practice in many specialisms with differing levels of prescriber authority.
Many nurses provide care within the ordering scope of physicians, and this traditional role has shaped the public image of nurses as care providers. However, nurses are permitted by most jurisdictions to practice independently in a variety of settings depending on training level. In the postwar period, nurse education has undergone a process of diversification towards advanced and specialized credentials, and many of the traditional regulations and provider roles are changing.
Nurses develop a plan of care, working collaboratively with physicians, therapists, the patient, the patient’s family, and other team members, that focus on treating illness to improve quality of life. Nurses may help coordinate the patient care performed by other members of an interdisciplinary healthcare team such as therapists, medical practitioners, and dietitians. Nurses provide care both interdependently, for example, with physicians, and independently as nursing professionals.
Hypoxia and Hypoxemia
Definition of Hypoxia:
Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level.
or
Hypoxia is a condition of insufficient oxygen anywhere in the body from the inspired gas to the tissues.
or
The term hypoxia is a condition where the tissues are not oxygenated adequately, usually due to an insufficient concentration of oxygen in the blood.
S/S/Clinical Features of Hypoxia:
The signs and symptoms of hypoxia can vary between different people, and by how long the symptoms have been present. Some of them include:
1. Dizziness or fainting (syncope)
2. Shortness of breath (dyspnea)
3. Confusion, lethargy, and/or lack of judgment
4. Headache 5. Rapid heart rate (tachycardia)
6. Elevated respiratory rate (tachypnea)
7. Euphoria and a sense of well-being
8. Tingling, warm sensations
9. Elevated blood pressure (hypertension)
10. Lack of coordination
11. Visual changes, such as tunnel vision
12. Elevated red blood cell count (polycythemia) in people with chronic hypoxia
13. A bluish tinge to the lips and extremities (cyanosis)
Types of Hypoxia:
As noted above, there are different types of hypoxia, or reasons that there is not enough oxygen in the tissues of the body. These include:
1. Hypoxic hypoxia (hypoxemic hypoxia)
2. Anemic hypoxia
3. Stagnant hypoxia (circulatory hypoxia)
4. Histiotoxic hypoxia
5. Metabolic hypoxia
Definition of Hypохетіа:
Hypoxemia (also known as low oxygen desaturation) is defined as an abnormally-low partial pressure of oxygen in the arterial blood.
or
Hypoxemia is an abnormally low level of oxygen in the blood and the more general term hypoxia is an abnormally low oxygen content in any tissue or organ.
