33
Expressed consent
The patient acknowledges he or she wants you to provide care or transport.
2. To be valid, the consent that the patient provides must be informed consent, which means that you explained the nature of the treatment being offered, along with the potential risks, benefits, and alternatives to treatment, as well as potential consequences of refusing treatment.
34
Implied consent
Applies to patients who are:
a. Unconscious
b. Otherwise incapable of making a rational, informed decision about care
2. Implied consent applies only when a serious medical condition exists and should never be used unless there is a threat to life or limb.
3. The principle of implied consent is known as the emergency doctrine.
4. Try to get consent from a spouse or relative before treating based on implied consent.
35
Involuntary consent
Applies to patients who are:
a. Mentally ill
b. In a behavioral (psychological) crisis
c. Developmentally delayed
2. Obtain consent from the guardian or conservator
a. It is not always possible to obtain such consent.
b. Many states have protective custody statutes that allow these individuals to be taken, under law enforcement authority, to a medical facility.
36
Minors and consent
1. The parent or legal guardian gives consent.
2. In some states, a minor can give consent.
a. Emancipated minor: an individual under the legal age who is legally considered an adult
b. Many states consider minors to be emancipated if they are married, if they are members of the armed services, if they are parents, or if living away from home and no longer relying on parents for support.
3. Teachers and school officials may act in place of parents (in loco parentis) and provide consent for treatment of injuries that occur in a school or camp setting.
4. If a true emergency exists and no consent is available, treat the patient under implied consent.
37
Forcible restraint
Necessary for patients who are in need of medical treatment and transportation but are combative and present a risk of danger to themselves or others
2. Forcible restraint is legally permissible.
a. Consult medical control for authorization and utilize law enforcement on the scene.

e. Consider calling ALS backup to provide chemical pharmacologic restraint.
38
A do not resuscitate (DNR) order gives permission to
withhold resuscitation.
1. “Do not resuscitate” does not mean “do not treat.” Even in the presence of a DNR order, you are still obligated to provide supportive measures (oxygen, pain relief, and comfort) to a patient who is not in cardiac arrest, whenever possible.
2. Each ambulance service should have a protocol to follow in these circumstances.

VIII. The Respiratory System: Physiology
A. The respiratory system’s function is to provide the body with oxygen and eliminate carbon dioxide.
B. Ventilation and respiration are two separate, yet interdependent functions of the respiratory system.
1. Ventilation: the movement of air between the lungs and the environment
2. Respiration: the exchange of oxygen and carbon dioxide in the alveoli and in tissues of the body
C. Respiration
1. Oxygen and carbon dioxide move across the membrane between the capillaries and alveoli via diffusion.
a. Diffusion is a passive process in which molecules move from an area with a higher concentration of molecule to an area of lower concentration.
D. The chemical control of breathing
1. The brainstem controls breathing by monitoring levels of carbon dioxide in the blood and spinal fluid.
2. Breathing is automatically controlled if the level of carbon dioxide or oxygen in the arterial blood is too high or too low.
3. Breathing occurs as the result of a buildup of carbon dioxide in the cerebrospinal fluid which causes the pH to decrease.
a. The medulla oblongata stimulates the phrenic nerve causing the diaphragm to contract.
b. The primary reason for breathing is to lower carbon dioxide levels not to increase oxygen levels.
4. Hypoxic drive “backup” system to control respiration.
a. The stimulus to breathe comes from low oxygen levels.
72
The nervous system control of breathing
1. Medulla oblongata
a. Responsible for initiating the ventilation cycle
b. Primarily stimulated by high carbon dioxide levels
c. Helps control the rhythm of breathing, initiate inspiration, set the base pattern for respiration, and send the signal to the diaphragm via the phrenic nerve

80
Electrical conduction system
a. A network of specialized tissue that is capable of initiating and conducting electrical current runs throughout the heart
b. Electrical impulses begin high in the atria at the sinoatrial (SA) node, travel to the atrioventricular (AV) node and bundle of His, and then move through the Purkinje fibers to the ventricles.
c. This movement produces a smooth flow of electricity, producing a coordinated pumping action.

a. Palpated most easily at the neck, wrist, or groin
82
Capillaries
1. Tiny blood vessels that connect arterioles to venules(veins)
2. Oxygen and nutrients pass from blood cells and plasma in the capillaries to individual tissue cells through the very thin walls of the capillaries.
3. Capillaries allow blood to move through them one cell at a time.
83
Veins
