  • Acute Respiratory Distress Powerpoint

    1. 1. BIEMS CEU Course <ul><li>Acute Respiratory Distress </li></ul>
    2. 2. Introduction <ul><li>ARD patients are a challenge for BLS technicians. </li></ul><ul><li>Many states limit the level of care that a BLS tech can provide. </li></ul><ul><li>Therefore, it is critical for basic EMS providers to have extremely sharp BLS level skills and to know when to pass the patient off to an ALS tech. </li></ul><ul><li>Much can still be done at the BLS level to save the patient’s life, as we’ll learn in today’s program. </li></ul>
    3. 3. Learning Objectives <ul><li>Identify and treat acute respiratory distress (ARD) secondary to congestive heart failure/pulmonary edema. </li></ul><ul><li>Identify and treat ARD secondary to chronic obstructive pulmonary disease (emphysema and/or chronic bronchitis) and asthma. </li></ul><ul><li>Identify and treat ARD caused by other common and not-so-common problems. </li></ul><ul><li>Discuss adjuncts of respiratory therapy commonly used by EMS provider with the ARD patient. </li></ul>
    4. 4.

    16. 16. Patient Medications <ul><li>Patient may already have respiratory nebulizers or atomizers. </li></ul><ul><li>EMS providers can usually assist patient with their prescribed inhaler. </li></ul><ul><ul><li>MAKE SURE THIS IS ALLOWED IN YOUR AREA. </li></ul></ul>
    17. 17. Recommendations for MDI or Nebulizer Assistance <ul><li>Examine the medications. </li></ul><ul><li>Ensure that the patient is alert enough to use the inhaler or nebulizer, and of significant importance is the patient’s tidal volume. </li></ul><ul><li>Shake the MID vigorously before use. Ensure it is not cold; room temperature is best. </li></ul><ul><li>Try and get the patient to exhale deeply before inhaling the medications. </li></ul>
    18. 18. Recommendations for MDI or Nebulizer Assistance (cont’d) <ul><li>After inhalation, see if the patient can hold his or her breath a bit for the medication to be absorbed. </li></ul><ul><li>The EMS provider's role is mainly “coaching” more than actually administering the medications. </li></ul><ul><li>Follow local protocol and consult medical direction as appropriate </li></ul><ul><li>REMEMBER: NEVER WITHHOLD OXYGEN! </li></ul>
    19. 19. Knowledge Assessment <ul><li>What is the “tool of choice” for providing ventilation to a patient in respiratory distress? </li></ul>

    30. 30. Learning Objective: Adjuncts of Respiratory Care <ul><li>Oxygen delivery equipment </li></ul><ul><ul><li>Come in various sizes </li></ul></ul><ul><ul><li>Must be tested every 5 years </li></ul></ul><ul><ul><li>NEVER USE ANY TYPE OF OIL NEAR O 2 EQUIPMENT </li></ul></ul><ul><li>“ D” cylinder – about 350 liters of oxygen (most commonly used by EMS providers) </li></ul><ul><li>“ E” cylinder – about 625 liters of oxygen </li></ul><ul><li>“ M” cylinder – about 3,000 liters of oxygen </li></ul>
    31. 31. Patient Care Equipment <ul><li>Nasal cannula </li></ul><ul><ul><li>Percentage of oxygen delivered is between 24 and 44 percent </li></ul></ul><ul><ul><li>Not to be used on hypoxic patients </li></ul></ul><ul><ul><li>Should be attached by inserting the prongs in the nostrils, around the ears and then under the chin; NOT in the nostrils and then back behind the head </li></ul></ul><ul><ul><li>Oxygen flow rates range between 4-6 liters per minute (LPM) but 2-3 LPM are not uncommon for patients on home oxygen via nasal cannula </li></ul></ul><ul><ul><li>Usually well tolerated by patients </li></ul></ul><ul><ul><li>Patients with inadequate tidal volume should NEVER have a nasal cannula applied for obvious reasons </li></ul></ul>
    32. 32. Non-rebreather Oxygen Mask <ul><li>Excellent 0 2 delivery tool </li></ul><ul><li>Important points: </li></ul><ul><ul><li>Should only be used in patients with adequate tidal volume. </li></ul></ul><ul><ul><li>Delivers between 80-90 percent oxygen. </li></ul></ul><ul><ul><li>Oxygen flow rates range around 12-15 LPM. </li></ul></ul><ul><ul><li>Always inflate the reservoir bag before applying to the patient by closing off the non-rebreather valve after turning on the oxygen flow. </li></ul></ul><ul><ul><li>Adjust flow rates to not allow bag deflation by more than one-third. </li></ul></ul>
    33. 33. Venturi Face Mask <ul><li>Used for long transport situations </li></ul><ul><li>Simple face mask with an adaptor </li></ul><ul><li>Adaptor accepts different color-coded inserts to control the percentage of oxygen </li></ul><ul><li>Oxygen tubing attaches to the insert </li></ul>
