Accepted 20 May 1996 Sunl K Snha, Joanne J Ncks, Steven M Donn Wth the ncreasng complexty of neonatal respratory care, pulmonary mechancs testng s emergng as a valuable tool to ad clncal decson makng n the management of ventlated nfants. Although there are as yet no publshed randomsed controlled clncal trals to suggest that pulmonary mechancs testng reduces mortalty or morbdty, t has-n conjuncton wth clncal, radologcal, and blood gas montorng-changed neonatal ventlaton from "good judgment" to "nformed judgment."' It s not surprsng that pulmonary mechancs testng s ncreasngly becomng an essental element n the assessment of patent status, therapeutc evaluaton, and management gudance of nfants wth ventlator dependence. A workng knowledge of pulmonary mechancs also mproves understandng of pulmonary physology and pathophysology and ther responses to mechancal ventlatory support.2 Unfortunately, these graphcal data contnue to be addtonal nformaton that the average bedsde clncan s currently unsure how to nterpret. The purpose of ths artcle s to dssemnate the nformaton on ths technque based on our experence usng the Brd Graphc Montor (Brd Products Corporaton, Palm Sprngs, Calforna, USA), whch n conjuncton wth ts Partner II Montor and VIP Brd Infant/ Pedatrc Ventlator, provdes a contnuous dsplay of graphc representaton of pressure, flow, or volume waveforms, or relatons between pressure-volume and flow-volume n the form of loops. It also gves numercal values for pressure, tdal volume, and flow, and can be used for establshng trends up to 24 hours. All the above graphcs can be obtaned as prntouts when used wth a standard computer prnter. Background Pulmonary mechancs montorng conssts of measurements of several varables whch defne dfferent aspects of lung functon. Although t has become popular to refer to ths type of analyss as "pulmonary functon testng," measurements of functonal resdual capacty (FRC) are not ncluded. Devces are becomng avalable to determne FRC at the bedsde, usng ether ntrogen washout or helum dluton technques, but at present the methodology s extremely expensve and mpractcal. Many dfferent pulmonary mechancs tests can be performed on ventlated nfants; only a few are commonly used n clncal practce. Specfcally, clncans are nterested n the pressure necessary to cause aflow of gas to enter the arway and ncrease the volume of the lungs. From these varables, several other measures of pulmonary mechancs can also be derved, such as pulmonary complance and resstance, and resstve work of breathng (energetcs). Complance s the term used to descrbe the relaton between a change n volume and the pressure requred to produce that change: C=AV/P. It gves nformaton about the elastcty of the lungs. Resstance s a result of frcton of gas flow aganst the ar conductng system. It s roughly measured as the change n transpulmonary pressure dvded by change n ar flow, and s an ndcator of arway functon. The product of complance and resstance determnes the tme constant, whch s a measure of how quckly the lungs can nhale or exhale, or how long t takes for the alveol and proxmal arway pressure to equlbrate. From these mechancs, whch can be dsplayed as numercal values or as graphc sgnals, useful nformaton can be obtaned and used for dagnosng specfc lung pathology, evaluatng dsease progresson, and determnng therapeutc nterventons. Although the facltes to montor arway pressure, tdal volume, and gas flow n ventlated nfants have exsted for some tme, ther applcaton has been mostly lmted to research purposes. However, recent advances n mcroprocessor technology for on-lne analyss of pulmonary mechancs have made such evaluatons easly avalable for bedsde clncal applcaton."4 Indeed, most of the new ventlators ether come wth, or have an opton for, a graphcal dsplay, and ths has become an essental feature of the newer ventlators avalable for nfant/paedatrc use. These on-lne systems obvate the need for nterruptng ventlaton. In addton, because of technologcal advantages, the sensors are very lght n weght and add mnmal dead space to the ventlatory crcut. Ths permts ther applcaton to even the smallest preterm nfants. Putatve advantages The ratonale of pulmonary mechancs testng n ventlated nfants s based on the assumpton that early dentfcaton of pulmonary prob- Arch Ds Chld Fetal Neonatal d: frst publshed as /fn.75.3.F213 on 1 November Downloaded from on 24 November 2018 by guest.

Methods -I The two forms of respratory graphcs most wdely utlsed n clncal practce are scalar waveforms and loops, both showng smultaneous relatons between pressure, volume, and ar flow. Although the software program whch montors and plots these graphs can also gve numercal values for each varable and calculated parameter, n practce, most of the useful nformaton can be derved by the vsual nspecton of ther morphology. Ths vares, accordng to specfc respratory functon status, provded allowance has been made for errors arsng from naccurate calbraton and artefacts. It s beyond the scope of ths paper to detal the specfc methods through whch the basc sgnals of flow, volume, and pressure undergo transducton to graphc or numerc dsplays, and several references are avalable for such purpose.78 However, the same mcroprocessor based technology used to provde patent trggered ventlaton s used n conjuncton wth hghly senstve transducers generally placed close to the endotracheal tube connector.

Top tracng shows neffectve spontaneous breaths; lower tracng shows mproved tdal volume delvery durng spontaneous breathng. OV the resstance and the complance, but because of the small dameter endotracheal tubes used n neonates, resstance s a more mportant determnant for ts confguraton. The expratory waveform can be used to observe changes n expratory resstance (fg 3) and the presence of gas trappng (fg 4). Normally, expratory flow reaches a zero flow state before the next breath begns. If the expratory tme s too short, the expratory flow fals to reach a zero flow state before the next breath starts, thus suggestng that gas trappng may be occurrng. A smlar appearance as shown n fg 4 can happen due to a large leak around the endotracheal tube, but ths can be dfferentated ether by usng the pressure-volume loops whch fal to close, or by montorng the dfference between nspratory and exhaled tdal volume. VOLUM AND PRSSUR WAVFORMS Measurement of tdal volume s becomng ncreasngly mportant n ventlatory management. The desred nspratory tdal volume for a ventlated breath ranges between ml/kg9 whle a tdal volume of ml/kg for spontaneous breaths generally ndcates sutablty of the nfant for weanng, provded ths s matched by satsfactory arteral blood gases whch reman the best ndex of ventlatory adequacy. Mnute ventlaton (tdal volume x respratory rate) s also currently beng evaluated as one of the predctor of weanng ( ml/kg/mnute),'0 especally n small nfants who have short nspratory tmes and a hgher respratory frequency. Unlke flow waveforms, both the nspratory and expratory phase of volume and pressure waveforms are postve and are therefore plotted above the abscssa. Breath-to-breath varablty and longer term trends are useful n selectng the mode of ventlaton and ndvdualsed adjustments to customse ventlator parameters for each patent. Fgure 5 shows dfferences n tdal volume delvery between mechancal and spontaneous breaths durng synchronsed ntermttent mandatory ventlaton (SIMV). The top waveform ndcates that spontaneous tdal volumes nbetween mechancally delvered breaths are neffectve. On the bottom graph, the nfant has much hgher spontaneous tdal volumes suggestng readness to wean. Pulmonary mechancs loops The loops are commonly used to demonstrate correlatons between arway pressure and volume, and arflow and lung volume (fg 6). Recently, attempts have also been made to produce a flow-pressure loop, but t s not yet avalable n clncal practce. At present, there s no agreed conventon regardng the manner n whch the loops are generated. Some devces draw them clockwse, others antclockwse. Some label upward deflectons as negatve, others postve.

Devces such as VIP Brd have an automatc scalng functon whch serves to reference the curve such that normal complance lne should be about 45. Over-dstenson s mpled when lttle or no change n volume occurs as ncreasng pressure s delvered. One way to recognse ths s to look at the termnal (upper) porton of the 25 pressure-volume loop and see how much tdal volume s beng delvered per unt of pressure change. Ths has been schematcally demonstrated n fg 8 created from a test lung for ze nstructve purposes. A useful parameter n ths case s the "C20."" Ths can be estmated by calculatng total complance of the lung n relaton to the complance of the last 20% of the breath (by dvdng tdal volume by peak pressure). If the complance of the last 20% s less than 80% of the total complance, t s suggestve of over-dstenson, and the ventlator should be adjusted to reach a C20 value hgher than 80%. Ths may be accomplshed by decreasng peak nspratory pressure, nspratory tme, and n some nstances, postve end L expratory pressure Pulmonary complance s a measurement of the dstensblty of the lung and s n a sense an ndcator of the functon of the lung parenchyma. Dsease processes that make the lung stffer and thus decrease pulmonary complance n neonates nclude surfactant defcency states, pneumona, pulmonary oedema, and pulmonary hypoplasa. Increased resstance, 45r such as that seen n bronchopulmonary dysplasa, causes a "bowng" or hysteress around the complance lne, and s an ndrect measure of the work of breathng (by ether the nfant or the mechancal ventlator) to move j the lungs.

The lower porton of the loop represents nspratory data; 5 the upper lmb descrbes the expratory correlaton. (Because there s no agreed conventon on drecton of nspratory and expratory lmb among varous manufacturers, t s mportant to become famlar wth the drecton of the er flow-volume loop on ndvdual machnes.) A flow-volume loop depcts changes n nspratory and expratory flow aganst volume changes, and s useful n detectng flow restrcton from arway abnormaltes. Under condtons of hgh arway resstance, flow s lower for a gven volume. Flow wll be lower on nspraton wth hgh nspratory resstance, or lower on expraton wth hgh expratory resstance.

Ths could also happen as a result of hgh ventlatory pressure or mprovement n lung functon after an mprovement n respratory dstress syndrome.

Lke radographs, graphcs should only be taken as suggestve of a condton rather than beng defntve. Pulmonary graphc waveforms can be msshapen because of nherent naccuracy of the measurement system (from calbraton dfferences between nspraton and expraton), or from temporary artefacts arsng from patent poston or mpedance to the gas flow by condensaton n the ventlatory crcut. It s mperatve to correct these ptfalls before acceptng the fndngs of graphcs as a gudance to change ventlatory settngs or assess the patent's clncal condton.'4 In ths partcular respect, the "trends" over a perod of tme seem to be of more value than ndvdual breath analyss. Although there are few data showng a benefcal or more cost effectve approach to neonatal ventlaton by the contnuous use of pulmonary mechancs montorng, the development and mplementaton of ths technology should make some studes feasble n the near future. Concluson On-lne pulmonary graphc analyss represents another major advance n respratory technology whch promses to mprove the safety and effcacy of neonatal mechancal ventlaton. Clncans are now afforded a breath-to-breath vew of pulmonary mechancs and respratory waveforms. Ths permts constant survellance of condtons such as ar trappng before they become clncally obvous, and the fne tunng of ventlator settngs to customse management accordng to the problems and responses of the ndvdual patent.
