291 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Terminology Mandatory breaths – controlled entirely by ventilator –Inspiration –Expiration –Volume/pressure of gas delivery

292 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Types of Ventilation Volume – clinician controls tidal volume; pressure can vary – can set rate, set volume Pressure – clinician controls pressure; tidal volume can vary - set rate, set pressure, need to monitor minute volumes No clinical consensus on preferred type

293 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Common Ventilator Modes Mode: describes the pattern of breath delivery Common modes –Assist control mode (ACM) –Synchronized mandatory intermittent ventilation (SIMV) –Pressure support (PS or PSV) –Pressure controlled ventilation (PCV)

294 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Assist Control Mode ACM delivers a preset volume or a preset pressure for each breath Patient can trigger a breath or the breath can be time triggered (CMV, A/C) Commonly used in care of in the postoperative patient

295 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Assist Control Mode Nursing Implications of ACM –As patient awakens, she or he may begin initiating breaths –Machine may not have time to deliver set volume –Patient can become hypoxic by attempt to breathe faster, stacking breaths –Pressure builds; lungs may be injured

296 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Assist Control Mode Nursing Implications of ACM –Nurse must monitor to assure that patient and machine are working together

297 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Synchronized Intermittent Mandatory Ventilation Very common mode in US SIMV sets the mandatory respiratory rate (V E ) Ventilator will deliver a set volume or pressure Patient can also initiate a breath –Ventilator waits for the patient, to breathe –Synchronizes delivery of breath in concert with the patient

298 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Synchronized Intermittent Mandatory Ventilation Nursing Implications of SIMV –Desirable for patient to “overbreathe” the machine; i.e. breathe faster than the V E –In SIMV, patient may initiate breaths, some are assisted and some are not –Team should evaluate V E, level of sedation or analgesia

299 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Pressure Support PS is a form of assisted ventilation Requires stable respiratory effort from patient IF ventilator senses negative pressure on inspiration –THEN ventilator supports the patient-initiated breath

300 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Pressure Support Does not control the rate or tidal volume –Therefore, usually used with SIMV, CPAP mode –PS not triggered unless patient breathes above the V E (mandatory rate)

301 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Pressure Support Nursing Implications of PS with SIMV –If patient does not “overbreathe” the machine, no benefit from PS –The nurse should assess the patient and talk to the team to determine a course of action

Wraa Pressure Control Ventilation Clinician sets rate and pressure Tidal volume is allowed to vary Usually reserved for patients with noncompliant lungs, difficult to ventilate and oxygenate Gas delivery distinguishes PCV from PS –Breath triggers rapid delivery of gas to reach set pressure, then the flow is decelerated

303 Copyright ©2010 by Pearson Education, Inc. Upper Saddle River, New Jersey All rights reserved. Medical Surgical Nursing: Preparation for Practice Kathleen S. Osborn | Annita Watson | Cheryl E. Wraa Pressure Control Ventilation Nursing Implications of PCV –The nurse should trend the V E and the expiratory volume over time –Volume decrease may indicate lungs are becoming less compliant –Adjust Pressure to Achieve the Same Volume
