What is Afebrile?
What is febrile?
- having or showing symptoms of a fever (adjective)
- Describes a fever
What is pyrexia?
Raised body temperature (noun)
Heat stroke is an example of positive feed back. True or false?
True! Failure of the hypothalamus to regulate body temperature. Meaning the body keep getting hotter and hotter. (Positive feed back)
What is Hypothermia?
This is when the body is unable to produce heat to maintain normal body temperature.
what is Dysrhythmias?
when the heart has an abnormal rhythm
Hypercatnic = ?
is when you have to much Carbon dioxide and that tell the body to breath
What is Eupnea?
Rregular, slow respiration (< 12/min)
Regular rapid respiration (> 20/min)
What is HYPERPNEA?
- gasping for air.
- rapid laboured, deep respiration
What is APNEA?
IT is the absence of breathing
Increased rate and depth of breathing. (to much carbon dioxide)
decreased rate and depth of breathing. (low levels of oxygen)
The pulse oximeter:
- Detects how much saturated the hemoglobin is with oxygen.
- Measures light wave emitted by Oxy. and CArbon dioxide
- Assesses arterial oxygen saturation
What is bloop pressure?
It is the force of blood pushing against he side of an artery.
is the maximum pressure exerted during ventricle contraction
Diastolic pressure is:
Is the pressure of heart at rest.
the action of listening to sounds from the heart, lungs, or other organs, typically with a stethoscope, as a part of medical diagnosis.
where do you apply the cuff when taking a patient blood pressure?
approx 2.5cm above the brachial artery
There are 5 phases in the series of sounds called "Korotkoff sounds"
- 1. Phase 1 - Tapping or thumping sound (systole blood pressure)
- 2. Phase 2 - occurs during deflation. A muffled or swishing sound.
- 3. Phase 3 - Blood flows freely through open artery. Sounds increases in crispness
- 4. Phase 4 - Sound becomes muffled again. (softer)
- 5. Phase 5 - Diastolic BP - Sound dissappers
- Is subjective (can not be seen)
- has an effect on VS (vital signs)
What are some physiological factors that control BP?
- Taking drugs. Ex - aspirin > thins blood > increases blood flow
- elasticity of vessel walls
- cardiac output
Pain assessment (P.Q.R.S.T)
- P = How did your pain start
- Q =what does your pain feel like? Quality of pain?
- R = Region/Radiation? does your pain go anywhere?
- S = signs and symptoms (redness/ swelling)
- T = time? (when did your pain start)
- U = Understanding (How do you interoperate your pain? have you felt this way before?
What are the FOUR phases of swallowing?
- 1. Oral Preparatory phase
- 2. Oral Phase
- 3. Pharyngeal phase
- 4. Esophageal phase
What is the oral prep phase
When the person eating is anticipated
what is the oral phase?
food collected and sealed between roof of mouth and tounge
what is the pharyngeal phase?
- This is where the epiglottis guides food past airways
- muscle of the pharynx contracts to move food towards the esophagus.
- food goes into esophagus
What happens in the esophageal phase?
contractions moving food along the esophagus towards the stomach
D.A.T = ?
Diet As Tolorated
what is Dysphagia
Different way to minimize aspiration risk?
- Check all plans and orders
- Diet texture
- bite size
- document in progress notes what you observed and who you told
What is Basal Metabolic rate
the rate at which the body uses energy while at rest to keep vital functions going, such as breathing and keeping warm.
What is the Valsalva manoeuvre?
the action of attempting to exhale with the nostrils and mouth, or the glottis, closed. This increases pressure in the middle ear and the chest, as when bracing to lift heavy objects, and is used as a means of equalizing pressure in the ears.
What is Orthostatic hypotension?
Low blood pressure occurring when someone stands up. (feeling of dizziness / head rush)
