Q

The Hazards of Oxygen

A

Oxygen supports combustion. Never allow combustible material (oil and grease) to touch the oxygen cylinder, the regulator, fittings, valves, or hoses, and keep the oxygen tanks away from all sources of fire while it is in use.

It must be used with caution with COPD patients (emphysema, chronic bronchitis, etc.). COPD patients have a low breathing stimulus. If large quantities of oxygen are administered to them, their stimulus to breathe will be removed – not allowing them to breathe properly. However, never withhold oxygen just start administering oxygen at low levels and increase as required.

Q

Postural (Orthostatic) Hypotension

A

Postural hypotension is a decrease in blood pressure. It occurs due to an abrupt change in position such as suddenly standing or sitting erect. It can also be caused by standing motionless in a fixed position and is common for the elderly and pregnant women. It can cause dizziness, syncope, blurred vision. If postural hypotension does occur treat as syncope.

Q

Possible Causes of Angina Pectoris..

A

This medical emergency is associated with insufficient blood supply to the myocardium and is usually due to the narrowing of coronary arteries (atherosclerosis). Other causes include coronary vasospasms, thrombus or anemia (a condition in which there is an inadequate supply of hemoglobin to carry oxygen). Angina pectoris is usually aggravated by exercise, tension, cold weather, or a large meal.

    Most common in adults
    Not due to allergic reactions
    Non-seasonal

Precipitating factors include emotional stress, inhaled fumes, viral infections, acetylsalicylic acid (ASA), cold air, strenuous exercise. Note: All patients are asymptomatic between attacks.

57
Q

Possible Causes of Hypoglycemia (Insulin Shock)

A

Hypoglycemia is most often caused by the treatment of diabetes, not the disease process itself. However, non-diabetics can also experience hypoglycemia if there is not enough sugar in the blood at a given time. Causes:

  • Perspiration
  • Increased anxiety
  • Possible unconsciousness
59
Q

Management of Hypoglycemia

  1. If the patient is conscious, ask when he or she last ate, whether he or she has taken insulin, and whether he or she brought insulin along to the dental appointment.
  2. Give oral glucose from emergency kit or a concentrated form of carbohydrate, such as a concentrated orange juice or soda pop. PURPOSE These substances will be absorbed rapidly into the bloodstream.
  3. Call for emergency assistance (9-1-1) if necessary.
  4. Provide basic life support (CPR) if the patient becomes unconscious.
  5. Monitor vital signs.
  6. Document emergency
60
