Oxygenation & Respiratory Function Flashcards
(59 cards)
Some chronic conditions result in loss of elasticity of the lungs causing air to get trapped in alveoli. Certain breathing exercises can strengthen the accessory muscles of respiration and result in better oxygenation
Effective Breathing
creates a smaller opening to air outflow and thus increases resistance to exhalation slightly. The end result is that the expiratory phase is lengthened, which helps prevent alveoli from collapsing while maximally expelling air from the lungs. Exhalation should take twice as long as inhalation. Teach patient to breathe in through nose (count “1…2…”) and exhale through pursed lips (count “1…2…3…4…”).
Pursed Lip Breathing
to strengthen the accessory muscles of respiration, which reduces air trapping and promotes complete emptying of the lungs. Have patients exhale with their hand on their abdomen, feeling for the inward motion of the abdomen. Have them work to increase their “push” with the abdomen by tightening the muscles to facilitate complete emptying.
Diaphragmatic breathing
One of the main benefits of Diaphragmatic breathing techniques is helping the patient
to “gain control” over breathing
Breathing is almost always easier in an
upright position
When a patient is having difficulty breathing, IMMEDIATELY
raise the head of the bed
Helps to remove secretions and keep alveoli open
Coughing
may be contraindicated for patients who have had eye, brain, or spine surgery because of the possible increase in intraocular or intracranial pressure.
Coughing
a set of techniques to help loosen and drain secretions from the lungs.
Chest Physiotherapy
is a gentle shaking pressure applied to the chest wall only during exhalation to shake secretions into larger airways.
Vibration
Used in conjunction with postural drainage. Rhythmic clapping on the chest wall over the area to be drained forcing secretions into larger airways so they can be expectorated. Hand is “cupped”
Chest percussion
Most commonly performed by Respiratory Therapist
Chest percussion
You use vibration most often with patients with
cystic fibrosis
A device that encourages deep inspiration (and, consequently, full expansion of alveoli) by providing a visual goal. The most common type is a disposable plastic device in which slow steady inspiration causes a ball to rise in a graduated plastic column.
Incentive Spirometry (IS)
Why are medications given by inhalation
The alveolar-capillary network absorbs medications rapidly
Deliver precise doses of medication directly to the lungs, dispersed through an aerosol spray, mist, or powder that penetrates lung airways. These devices consist of a mouthpiece and actuator into which a medication canist
Pressurized Metered-Dose Inhalers (pMDIs)
Used for asthma, emphysema, COPD, and bronchitis.
Pressurized Metered-Dose Inhalers (pMDIs):
are short acting and provide immediate relief for acute respiratory distress. They are for relief of symptoms.
“Rescue” medications
are used daily at scheduled times to prevent acute respiratory distress. Many of them are corticosteroids. They treat the underlying pathology
“Maintenance” medications
Patients may use a _______ with pMDIs.
spacer
allow the particles of the medication to slow down and break into smaller pieces therefore leading to improved drug absorption in the patient’s airway
Spacers
hold medication in a powdered form and create an aerosol when the patient inhales through the reservoir holding the medication. This requires less hand-breath coordination. The device is activated when the patient breathes; no spacer is needed
Dry Powder Inhalers (DPIs)
releases medication when the patient lifts a lever, but the medication doesn’t flow out until the patient inhales. Useful for patients with hand-breath coordination issues, or patients who have so little hand strength that they can’t push the actuator down enough to release the dose.
Breath-Actuated Inhaler (BAI)
If patient is using a bronchodilator (rescue) AND a steroid inhaler (maintenance), instruct the patient ______________FIRST (to open the airway) and then use the steroid inhaler
to use the bronchodilator
