HYPed about O2
Low oxygen levels within the blood
Hypoxemia
Pressure in lungs during inspiration
Inspiratory pressure
How this amount in the blood is determined
ABG - arterial blood gas
6-10 LPM and FiO2 35-50%
Simple Mask (SM)
Humidification must be used at this level or greater
4 L
Low O2 levels in the tissues
Hypoxia
Amount of air left in lungs at expiration
Expiratory pressure
Positive _______ pressure decreases CO2
expiratory
10-15 LPM and FiO2 30-40%
Face Tent (FT)
Used most often for O2 administration and for 1-4 LPM
Nasal cannula
Some conditions that cause hypoxemia
COPD, asthma, PNA
Volume of air inspired and expired with each breath
Tidal volume
Decrease in __ _____ may increase build up of CO2
lung compliance
Mixes oxygen and ambient air to achieve desired FiO2 (24-60%) at a rate ranging from 5-15 LPM
Venturi Mask (VM) - has different colored valves specific for desired flow and FiO2
Remove O2 and continue to monitor; inform MD
Contributing factors to hypoxemia
smoking, aging, high altitude
Average tidal volume for adult
This mask allows CO2 to be exhaled freely
Nonrebreather (NRB)
Inflated bag with 100% oxygen, but not often used because the reservoir mixes O2 and exhaled air
Partial Rebreather (PR)
These should be stored in a cool, dry place and handled with a designated hand truck
Portable O2 tank
Signs of hypoxia
cyanosis, confusion, tachycardia, difficulty breathing
Percentage of oxygen in blood at capillary level
O2 saturation
Therapy for decreased lung compliance by administering O2 and decreasing CO2
Ambient air cannot enter reservoir but exhaled air can escape
Nonrebreather Mask (NRB)
Guidelines including "do not smoke in the home", "keep at least 10 feet away from heat sources", and "ensure smoke and carbon dioxide alarms are working properly" are examples of this.
