- conjunctiva
- membrane lining eyelids
- cyanosis
- blue-gray skin from reduced blood oxygen
- diaphoretic
- profuse sweating
- hyper/hypotension
- high/low BP
- stridor
- harsh inspiratory sound w/ upper airway obstruction
- tachycardia
- HR > 100 BPM
- bradycardia
- HR < 60 BPM
- hypoxic drive
- oxygen sensors that modulate respiration; less sensitive than CO2 sensors in brain stem
- agonal respiration
- gasping, inadequate breaths--should follow CPR protocol
- epiglottis
- prevents food/liquid from entering trachea
- priapism
- continual erection due to spinal injury
- hypoxia
- tissues receive inadequate oxygen
- pulmonary edema
- fluid accumulation in lungs; oxygen transfer to blood less efficient
- retractions
- skin pulling around ribs on inhalation
- apnea
- lack of spontaneous breathing
- contusion/ecchymosis
- bruising
- epistaxis
- nosebleed
- hematoma
- blood in soft tissue
- hematemesis
- blood in vomit
- hemophilia
- lack of blood clotting factors
- edema
- fluid between cells, causing swelling
- dyspnea
- difficulty breathing
- aneurysm
- swelling of a portion of artery, causing weakening of arterial wall
- syncope
- fainting
- emphysema
- loss of elasticity around air spaces. can cause spontaneous pneumothorax
- pulmonary embolism
- blood clot from lower body lodges in pulmonary artery--no gas exchange in areas of blocked blood flow
- COPD
- dilation of alveoli because of chromic bronchial obstruction
- ischemia
- insufficient oxygen causes chest pain
- emesis
- vomiting
- asystole
- cessation of heart contractions
- atherosclerosis
- plaque in arterial walls narrows lumen--> MI or cardic arrest
- thrombosis
- clotting of cerebral arteries
- dysarthria
- slurred speech, often associated with right hemisphere stroke
- gastric distention
- stomach inflates with air
- pneumothorax
- pleural space fills with air, pressure can collapse lung
- chest compliance
- chest's ability to expand on inhalation
- cardiac arrest
- no pulse--begin CPR
- subcutaneous emphysema
- air around thorax
- comminuted fracture
- bone broken into many pieces
