Clinical 1 Quiz 3
Aerosol, IS, Pulse Ox
| Term | Definition |
|---|---|
| Common Indications for Aerosol Treatment | -Moblize secretions -Improve alveolar ventilation -Administer specific medication to lower/upper airways |
| Aerosol Medications include | -Bronchodilators (anticholinergics/beta andrenergics) -Antibiotics, Antiviral, Antifungal -Anti Inflammatory (corticosteroids) -Surfactant -Vasoconstrictors -Mucolytics |
| Precautions and Hazards of Aerosol Treatment | - Complication of Administration - Bronchospasm with hyperreactive airways -Exposure to Therapist (EX Ribavirin) -Under/Overdosing |
| Small Volume Nebulizers | 3-5ml dose Flow 6-8 Lpm MMAD of 1-5 microns Only about 10% of the actual dose of the nebulized medication reaches lower airways |
| Assessments | Pre/During/Post WOB (Accessory Muscles?Patter?RR?) HR Breath Sounds (Reduction?Increase Wheeze?) Cough Frequency/Production FEV1 or PEF |
| MDI Indications | -Administration of inhaled medications to intubated and non-intubated patients -Transition patient from aerosolized medication -Enhance patient convenience and compliance with use of inhaled medications |
| MDI Precaustions/Hazards | Bronchospasm Paroxysmal coughing Poor technique resulting in inadequate dosing of medication Increased airway resistance and air-trapping from airway collapse Adverse reaction to medication, propellants, or additives |
| Always use MDI with what additional device? | Valve Holding Chamber |
| What does a Valvue Holding Chamber do? | Reduce impaction of the drug more inhaled drug Improve hand to breath coordination Reduce undesirable taste Reduce cold aerosol induced hyper-reactivity of the airways Decrease risk of fungal infection oral candidiasis |
| Propellant | In MDI a substance with a high vapor pressure that propels the metered dose of medication out the actuator nozzle for dispersal into the airway |
| MDI Technique | 1. Shake Canister 2. Puff into air if not recently used 3. Hold canister vertical and connect to VHC which is horizontal 4. Exhale and bring MDI to lips 5. Begin slow deep inspiration and actuate canister 6. Hold for 10 seconds then exhale |
| How long should a patient wait between MDI puffs? | 30sec-1 minute Decreases side effects and allows for absorbance |
| DPI Indications | Dry Poweder Inhaler Maintenance drugs Portibale Convenience Patient is sensitive to cold aerosols |
| DPI Precaustions/Hazards | Generate enough flow (40-50) High humidity causes clumping of powder |
| DPI Technique | 1. Exhale bring DPI to mouth 2. Break capsule by release button on DPI 3. Inspire fast and deep |
| Pulse Ox Indications | To monitor the adequacy of oxygenation To determine a patient’s response to oxygen therapy To satisfy requirements for reimbursement by health care insurers |
| Pulse Ox Precautions/Hazards | Over/Underestimate HgB in presence of abnormal HgB, excessive light, dyes, anemia Poor perfusion, motion, nail polish |
| Spectrophotometry | 2 lights used to determine Sp02 by abosrbance and pulse flow |
| Photoplethysmography | Changes in the puslitile flow graphed/traced on monitor (aka pleth) |
| Oxygenated HgB attracts what light? | infrared light |
| Deoxygenated HgB attracts what light? | red light |
| Functional HgB Saturation | Pulse Oximeter Found by dividing by concentration of HgB capable of carrying o2 |
| Fractional. HgB Saturation | CO-Oximeter Found by dividing by 4 forms of HgB (O2Hb, HHb, COHb and MetHb) |
| Pulse Oximeter values are within what percent of actual arterial saturation? | 3-5% |
| If pulse ox is below ____% pulse ox cannot be relied on and a therapist can validate Sp02 accuracy by _________________. | 80% Arterial Blood Gas |
| Pulse Wave/Amplitude Bar | 5 bpm is normal Shown on monitor or with bars |
| Probe Types | Finger Ear Adhesive Wrap |
| Pulse Ox Assessment | Therapist finding a pulse, assuring strong correlation with pulse ox Patient’s color WOB Patient statements |
| Important! | Never believe a pulse oximeter value that isn’t consistent with the clinical appearance of the patient. |
| IS Indications | Atelectasis Mobilize secretions Post Surgical Restrictive lung defect Dysfunction of the diaphragm |
| IS Precautions/Hazards | Excessive muscle weakness Hypoxemia Unstable incisions Neuromuscular weakness Vital Capacity less than 10ml/kg of IBW Inspiratory Capacity less than 1/3 of predicted value |
| Incentive Spirometry, Coughing, and deep breathing techniques require the patient to be __________ in order to be successful | Alert and oriented. Able to follow simple directions |
| Incentive Spirometry goal | get patients to breath more deeply 5-10 maximal inspirations qh |
| IS Technique | 1. Set goal based on chart values 2. Patient takes a slow deep inspiration 3. Take best of 3 attempts |
| IS Assessments | Breath Sounds WOB HR Improved oxygenation (↑PaO2, ↑SpO2 and ↓P(A-a) O2) Restoration of pre-operative vital capacity or inspiratory capacity Chest x-rays comparison |
