begins with the onset of contractions as the fetus enters the birth canal and ends with the cervix is fully dialated. Other signs may be bloody show or the rupture of the amniotic sac.
Second Stage of Labor
begins with the fetus begins to enter the birth canal and ends when the infant is born.
when the perineum begins to bulge significantly and the top of the infant's head begins to appear at the vaginal opening
Third stage of labor
begins with the birth of the infant and ends with the delivery of the placenta. This process may take up to 30 min.

symptoms. Headache, seeing spots, swelling in the hands and feet, anxiety and high blood pressue.
Treatment of eclampsia
lie the patient on her side - preferable her left side, maintain an airway, and provide supplemental oxygen; if vomiting occurs, suction the airway, provide rapid transport and call for ALS intercept.
supine hypotensive syndrome
Dizziness and a drop in blood pressure caused when the mother is in a supine position and the weight of the uterus, infant, placenta, and amniotic fluid compress the inferior vena cava, reducing return of blood to the heart and cardiac output.

an upright position in which the patient's head and chin are thrust slightly forward and the patient appears to be sniffing; most commonly seen in children
high or low pitched sound heard usually during expiration; indicates a partial lower airway obstruction
an "uh" sound heard during exhalation; reflects the pediatric patient's attempt to keep the alveoli open by increasing pressure in the chest cavity; indicated by inadequate oxygentation
Assessing Circulation Pediatric
a pulse may be difficult to palpate if it is weak, very fast or very slow. Infants palpate the brachial pulse or the femoral pulse, in children older then 1 hear palpate the carotid pulse. Strong central pulses indicate that the child is not hypotensive however this does not rule out the possibility of compensated shock
Less than 60 beats/min
Bradycardia is almost always and ominous sign in pediatric patients. If the heart rate is fast, you need to investigate the cause. If the heart rat is slow _________ or absent especially in an unconscious infant or child you must begin CPR immediately.

Early nerve agents which were developed by German scientists in the period after WWI and into WWII. There are three such agents: sarin, soman, and tabun.
A nerve agent that is one of the G agents; a highly volatile colorless and odorless liquid that turns from liquid to gas within seconds to minutes at room temperature.
A nerve agent that is one of the G agents; twice as persistent as sarin and five times as lethal; it has a fruity odor, as a result of the type of alcohol used in the agent, and is both a contact and inhalation hazard that can enter the body through skin absorption and through the respiratory tract.
A nerve agent that is one of the G agents; is 36 times more persistent than sarin and approximately half as lethal; has a fruity smell and is unique because the components used to manufacture the agent are easy to acquire and the agent is easy to manufacture.
V agent (VX)
One of the G agents; it is a clear, oily agent that has no odor and looks like baby oil; over 100 times more lethal than sarin and is extremely persistent.
is used to block the nerve agent from affecting the body, but because the nerve agent remains a long time 2-PAM chloride is used to eliminate the agent from the body.

Mechanism of Injury
This is one of the most crucial elements in history taking in assessing a trauma incident.
this type of injury is often seen in rear-end collisions, in which the head and or neck is not restrained by a headrest. The passengers body and torso are propelled forward and the head and neck are left behind.
This type of collision the movement is to the side and the passenger's shoulders and head whip toward the intruding vehicle. Key to remember that the cervical spine has little tolerance for lateral bending.

Signs and symptoms of internal bleeding
-pain, tenderness, bruising,guarding or swelling
-broken ribs, bruises over the lower part of the chest or a rigid, distended abdomen
signs of perfusion problems
a systolic blood pressure of less that 100mm Hg with a weak rapid pulse, cool, most skin that is pale or gray

-high blood pressure
-digital trauma (nose picking)
there is a break in the surface of the skin or the mucous membrane, exposing deeper tissues
the soft tissue damage occurs as a result from thermal heat, frictional heat, toxic chemicals or nuclear radiation
when an area of the body is trapped form longer than 4 hours and arterial blood flow is compromised. Can lead to renal failure and death
swelling that occurs whenever tissues are injured the cells then leak fluid and the interstitial pressure builds up enough to compress the tissue and cause further damage.
wound of the superficial layer of the skin caused by friction when a body part rubs or scrapes across a rough or hard surface
is a injury resulting from a sharp, pointed object, such as a knife, ice pick, splinter or bullet
rules for treating an evisceration
-do not touch or move the exposed organs.
-cover the wound with sterile gauze moistened with sterile saline solution and secure with an occlusive dressing.
rules for treating a impaled object
-do not attempt to move or remove the object, only if it is causing an airway obstruction or interferes with CPR.
-Remove clothing covering injury and control bleeding
-stabilize the object effectively
when enough air is sucked into a blood vessel, it can actually block the flow of blood in the lungs, sending the patient into cardiac arrest.
5 factors to determine burn severity
1. What is the depth of the burn
2. What is the extent of the burn
3. Are any critical areas (face, upper airway, hands, feet, genitalia) involved
4. Does the patient have any preexisting medical conditions or other injuries?
5. Is the patient younger then 5 year or older then 55 years.

brain injury refers to a multitude of processes that increase the severity of a primary brain injury and negatively impact the outcome.
when the brain slams into the rear of the skull creating a front-and rear injury
increased systolic blood pressure, decreased pulse rate, and irregular respiration. This triad is caused by cerebral edema and increased intracranial pressure.
bleeding occurs into the subarachnoid space where CSF circulates. It results in bloodly CSF and sings of meningeal irriation
known to be mild traumatic brain injuries. Generally a closed injury with a temporary loss or alteration of part or all of the brain's ability to function without demonstratable physical damage to the brain
more serious then a concussion because it involves physical injury to the brain tissue which may sustain long-lasting and even permanent damage.
injury of the spine that occures when the vertebrae are no longer aligned. Sometimes refered to as "step off" where the spinous process may be palpable on physical examination.
Rules for treating spinal injuries
-oxygen delivered by NR is always indicated for patients with head and spinal injuries.
-Pulse oximeter values should be maintained above 90%
increased blood pressure, decreased heart rate and irregular respiration (central neurogenic hyperventrilation and Biot respiration). Referred as a herniation syndrome where the intracranial pressure is so great that if forces the brain stem and the midbrain through the foramen mangnum.

-it prevents you from properly immobilizing the spine
-it allows excessive head movement or the patient is in cardiac arrest
Muscles controlled by C6 and C7 spinal nerves
muscles extending between the ribs, intercostals, that allow the chest to expand on contraction and allow ventilation to occur are controlled by these nerves

damage to the spine below this point a patient will lose the power to move the intercostal muscles but the diaphragm will still contract
Damage at or above C3
damage to the spine at this point can cause patients to lose their ability to breath entirely
an abnormality associated with multiple fractured ribs, in which one segment of the chest wall moves opposite the remainder of the chest (often referred to as flail segment)
commonly called a collapsed lung. accumulation of air in the pleural space through a hole in the chest wall or the surface of the lung as the patient attempts to breath causing the lung on that side to collapse.

any pneumothorax that does not result in major changes in the patient's physiology. (commonly the result of blunt trauma)
A life-threatening collection of air within the pleural space; the volume and pressure have both collasped the involved lung and caused a shift of the mediastinal structures to the opposite side.
accumulation of blood in the pleural cavity (the space between the lungs and the walls of the chest)
when the protective membrane around the heart (pericardium) fill with blood or fluid, perhaps from a ruptured, torn or lacerated coronary artery or vein.
paradoxical motion, the detached portion of the chest wall moves opposite of normal. Occurs when ribs are fractured in more than one place or the sternum is fractured along with several ribs.
when the pulmonary alveoli become filled with blood and the fluid accumulates in the injured area, leaving the patient hypoxic.

2. Apply the appropriate splint and elevate the extremity
3. If swelling apply cold packs
4. Prepare for transport
Function of splinting
-prevents further damage
-prevents laceration of the skin by broken ends
-restriction of distal blood flow from pressure of bone ends on blood vessels
-excessive bleeding of the tissue at the site can be controlled
-reduces risk of pain by movement of bone ends
-reduces risk of paralysis of extremities resulting from a damaged spine.
Area a splint should be applied
- in fracture of the shaft of any bone, be sure to stabilize the joints above and below the fracture
-in injuries around the joint be sure to stabilize bones above and below.
Splinting the hand and wrist
1. cover all wounds with a dry, sterile dressing
2. support the injured limb, from the injured hand into the position of function
3.Soft roller bandage into the palm of the hand
4. secure the entire length of the splint with a soft roller bandage.

5 types of body heat loss
conduction- direct transfer of heat from a part of the body to a colder object
convection- occurs when heat is transferred to a circulating air
evaporation- conversion of any liquid to a gas
radiation- transfer of heat by radiant energy (invisible light)
respiration- causes body heat to be lost as warm air in the lungs is exhaled into the atmosphere and cooler air is inhaled.
it is diagnosed when the core temperature of the body and or organs falls below 95 degree F (35 degree C)
when the core temp is between 90 and 95. the patient is usually alert and shivering. Movement to create heat. pulse and respiratory rate are usually rapid. Skin appears red, may have blue lips or finger tips.
when the core temp is less than 90, the patient's shivering stops and muscular activity decreases, fine muscular activity ceases and as temp fall further all muscle activity stops.
exposed body parts become very cold but not frozen (also called chilblains, immersion foot). Skin is pale and cold to touch, not painful.

can be transmitted by contact (direct or indirect) , are either airborne, food-borne, or vector-borne
consent given verbally or otherwise that acknowledges that he or she desires care.
permission for treatment given by a competent patient after the potential risks, benefits, and alternatives have been explained
when a patient who is unable to give consent is given treatment under the legal assumption the he or show would want treatment
patients who are mentally ill, behavioral crisis, developmentally delayed- incompetent and unable to give informed consent (law officials can give consent for this)
physically preventing an individual from initiating any physical actions. Medical control must authorize this or local law enforcement
Right to refuse treatment
adults how are conscious, alert, and appear to have decision making capacity have the right to deny treatment or withdrawal from any treatment
Ex. Do Not Resuscitate (DNR). Valid written documentation from a physician giving permission to deny treatment.
Vaild Advance directives
Clear statement of patients medical problem
signature of patent or legal guardian
signature of one or more physicians
expiration date and must be 12 months valid
Initiating Care with the sign of death
absence of DNR and
body is still warm and intact except for case of hypothermia
blood settling to the lowest point of the body, causing discoloration of the skin
individual that has expressed a wish to donate organs, treat in same way that you would treat any other patient
unilateral termination of care by the EMT without the patients consent and with out making provisions to another medical professional with equivalent or higher skills
factors determining competence
intellect, age, drug impaired, significant pain, language and rational of a patient.
Good Samaritan law
Statutory provision enacted by states that protect citizens from liability and errors in giving good faith emergency care
open ended questions
questions in which the patient needs to provide some level of detail to give an answer.
close ended questions
question with short one word responses. Important when patients are unable to provide long or complete answers
Patient Care Report (PCR)
pre-hospital care report, the legal document used to record all aspects of the care your patient received, from initial dispatch to arrival.
Components of PCR -patient care report
level of consciousness
Refusal of Care Documentation
-indicate persuasion to go to hospital
-make sure pt. is informed of decision
-willingness to return
-sign refusal form
written documents that have been signed by the EMS system's medical director outlining specific directions
supine position, only lower extremities are elevated 6" to 12" to increase blood flow to the brain.
passive process in which molecules move from an area with higher concentration to an area of lower concentration
back up system for the CO2 receptors in the brain stem. Areas in the brain, wall of aorta and corotid arteries act as O2 sensors
special stretch receptors in the chest wall which are able to detect if the lungs are too full or too empty.
pulse at radial artery
pulse at brachial artery
posterior tibial artery pulse
dorsalis pedis pulse
steps of patient assessment
1. Scene size up
2. Primary Assessment
3. History Taking
4. Secondary Assessment
Components of Primary Assessment
Level of consciousness
Patient priority and transport
Common test evaluates patients ability to remember four things:
Person, Place, Time and Event
Glasgow coma scale
rating system that provides baseline data on the patients overall neurological status
Primary assessment of airway
rhythm, regular or irregular
quality/character of breathing
depth- tidal volume
congested breath sounds presense of mucus in lungs. Low pitched, noisy sounds that are most prominent on expiration
indentations above the clavicles and n the spaces between the ribs with use of the accessory muscles
chief complaint, all times of assessments and interventions, age, sex, past medical history, patient condition and current health status
Signs and symptoms
Past medical history
last oral intake
Events leading up to injury or illness
Provoke or palliation (pain better or worse)
Quality of pain
Radiate - does pain radiate
Severity - scale from 1 to 10
to perform a systematic physical examination of the patient, head to toe full body scan or systematic focusing on one area
is a noninvasive method that can quickly and efficiently provide information on a patient's ventilatory status
when only one section of the chest rises on the inspiration while another area of the chest falls
exchange of oxygen and carbon dioxide between the systemic circulatory and the cells of the body
metabolism that does not require oxygen but will result in less ATP and build of lactic acid
blood entering the lungs from the right side of the heart bypasses the alveoli and returns to the left side of the heart in an unoxygenated state
life-threatening collections of air within the pleural space; volume and pressure have both collapsed the involved lung causing a shift of the mediastinal structures to the other side
respirations that are irregular respiratory patterns in which patient breaths with an increasing rate and depth of resp. followed by period of apnea
Contradiction for a Nasopharyngeal Airway
severe head injury with blood draining from the nose
history of fractured nasal bone
Indication for Oropharyngeal Airway
unresponsive pt. without a gag reflex
apeic patient being ventilated with bag-mask
Indication for Nasopharyngeal Airway
semiconscious or unconscious patients with a intact gag reflex
patients who would not tolerate a oropharyngeal airway
Rules for suctioning
never suction the mouth or nose for more than 15 seconds
apply suction in circular motion as you withdraw catheter
preferred way of giving oxygen in a prehospital setting to patients who are breathing adequately but show signs of hypoxia
delivers oxygen directly through the nostrils. Patients who can breath through mouth and may require humidification
bag mask device
oxygen delivery device that should be used when you need to deliver high concentrations of oxygen to patient who are not ventilating adequately 1 squeeze every 5 sec
Continuous Postive Airway (CPAP)
breathing apparatus indicated for patients experiencing respiratory distress who own compensatory mechanisms are not enough to keep up oxygen demand. typically pulmonary edema or obstructive pulmonary disease
Rules for dental applicances
leave dentures in place to provide more structure unless they become loose in which they should be removed
Routes of Administration
IV - intravenous
SC - sub cutaneous
IM - intramuscular
