the blockage of the coronary arteries
use when there is potential for danger
Necessary to move patient: With altered level of consciousness, With inadequate ventilation, In shock, In extreme weather conditions, Rapid extrication technique requires a team of knowledgeable EMTs.
used when both scene and patient are stable
Non urgent move
used in difficult to reach areas
useful for confined spaces. Does provide immobilization
immobilize seated patients
Alternative to backboards for immobilizing geriatric and pediatric patients
remove patients from remote locations
Position of comfort for chest pain and respiratory problems
is both the mechanical weight-bearing base of the spinal column and the fused central posterior section of the pelvic girdle.
How does oxygen reach body tissue?
through breathing and circulation
What Structures help us breathe?
diaphram, chest wall muscles, accessory muscles of breathing, nerves from the brain and spinal cord to those muscles
What does the upper airway consist of ?
nose, mouth, jaw, oral cavity, pharynx, larynx
What is the main function of the upper airway?
Warm, filter and humidity air as it enters the body
filters out dust and small particles, warms and humidifies air as it enters the body
Lower airway function
deliver oxygen to the alveoli
Lower airway includes
trachea, bronchi, lungs
the pace between the lungs
these systems work together to ensure a constant supply of oxygen and nutrients is delivered to cells.
Respiratory and cardiovascular system
the physical act of moving air into and out of the lungs
active, muscular part of breathing, the diaphragm and intercostal muscles contract.
passive process, diaphragm and intercostal muscles relax, smaller thorax compresses air into the lungs
infections, allergic reaction, unresponsiveness (tongue obstruction)
trauma, foreign body airway obstruction
atmospheric pressure, partial pressure of O2
pneumonia, pulmonary edema, COPD/ emphysema
Cheyne stokes often seen in patients with
stroke or head injury
irregular or unidentifiable pattern, may follow serious head injuries
deep, rapid respirations, common in patients with metabolic acidosis
