Pereira, Ehab Daoud","doi":"10.53097/JMV.10003","DOIUrl":"https://doi.org/10.53097/JMV.10003","url":null,"abstract":"Background: Quantification of the patient’s respiratory effort during mechanical ventilation is very important, and calculating the actual muscle pressure (Pmus) during mechanical ventilation is a cumbersome task and usually requires an esophageal balloon manometry. Airway occlusion pressure at 100 milliseconds (P0.1) can easily be obtained non-invasively. There has been no study investigating the association between Pmus and P0.1. Therefore, we aimed to investigate whether P0.1 correlates to Pmus and can be used to estimate actual Pmus Materials and Methods: A bench study using lung simulator (ASL 5000) to simulate an active breathing patient with Pmus from 1 to 30 cmH2O by increments of 1 was conducted. Twenty active breaths were measured in each Pmus. The clinical scenario was constructed as a normal lung with a fixed setting of compliances of 60 mL/cmH2O and resistances of 10 cmH2O/l/sec. All experiments were conducted using the pressure support ventilation mode (PSV) on a Hamilton-G5 ventilator (Hamilton Medical AG, Switzerland), Puritan Bennett 840TM (Covidien-Nellcor, CA) and Avea (CareFusion, CA). Main results: There was significant correlation between P 0.1 and Pmus (correlation coefficient = - 0.992, 95% CI: - 0.995 to -0.988, P-value<0.001). The equation was calculated as follows: Pmus = -2.99 x (P0.1) + 0.53 Conclusion: Estimation of Pmus using P 0.1 as a substitute is feasible, available, and reliable. Estimation of Pmus has multiple implications, especially in weaning of mechanical ventilation, adjusting ventilator support, and calculating respiratory mechanics during invasive mechanical ventilation.

Recent report suggested two different phenotypes of patho-physiology (type L and type H). Type L is characterized by low elastance and low ventilation-perfusion mismatch ratio (V/Q), while type H is more consistent with the classic acute respiratory distress syndrome (ARDS) characterized by high elastance, and increased right to left shunt. The role of perfusion deficits has been clearer with the discovery of micro and macro vascular thrombi in the lung vascular endothelium. Prone position has gained interest in research and guidelines as a maneuver capable of improving ventilation and perfusion. Airway pressure release ventilation (APRV) can theoretically improve hypoxemia due to ventilation/perfusion mismatch in patients with COVID-19 compared to other conventional strategies. From this perspective, we may have to consider perfusion as the major problem in the disease process more than just ventilation. More studies are required to explore the role of perfusion and the different ventilatory strategies to best manage those patients.

Due to this shortfall, the surge of increasing number of patients to limited resources of mechanical ventilators has reinvigorated the interest in the concept of split ventilation or co-ventilation (ventilating more than one patient with the same ventilator). However, major medical societies have condemned the concept in a joint statement for multiple reasons. Materials and Methods: In this paper, we will describe the history of the concept, what is trending in the literature about it and along our modification to ventilate two patients with one ventilator. We will describe how to overcome such concerns regarding cross contamination, re-breathing, safely adjusting the settings for tidal volume and positive end expiratory pressure to each patient and how to safely monitor each patient. Main results: Our experimental setup shows that we can safely ventilate two patients using one ventilator. Conclusion: The concept of ventilating more than one patient with a single ventilator is feasible especially in crisis situations. However, we caution that it has to be done under careful monitoring with expertise in mechanical ventilation. More research and investment are crucially needed in this current pandemic crisis.","PeriodicalId":73813,"journal":{"name":"Journal of mechanical ventilation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43319368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
