fast respirations
What does hyperpnea mean?
deep respirations
What does apnea mean?
no respirations
What is blood pressure?
BP is the pressure required to move oxygenated blood through the heart. The pressure depends on the energy needed for the heart to pump, the elasticity of its arterial walls, and the volume and viscosity of the blood.
What is the formula for blood pressure?
BP= Cardiac output (CO) X Peripheral Resistance (PR)
What is the formula for cardiac output (CO)?
CO= Stroke volume + Heart rate
What does systolic mean?
Maximum pressure at the end of the stroke output (emptying) of the left ventricle
What does diastolic mean?
Minimum pressure at the end of left ventricular filling (resting) of the heart
What nonpharmacologic factors decrease blood pressure?
-Dehydration
What is orthostatic hypotension?
significantly lowered blood pressure upon standing, associated with dizziness/fainting
What nonpharmacologic factors increase blood pressure?
- Lack of sleep
- Pain
- Stress
- Smoking
- Licorice

What is air conduction hearing?
uses the bones of the middle ear to amplify sound waves
What is bone conduction hearing?
uses sound waves traveling on the surface of the bones of the skull to transmit sound to the cochlea without using the ear canal

(sclera) lines the surface of the eyeball and inner part of the lids
What is the retina?
thin film that lines the inner globe and is composed of billions of nerve endings that respond to light and color
