Sinha and colleagues 7 found weak and non-significant association between VCO 2 and VR. They attributed this to the smaller and short-lived variation in VCO 2 compared with the larger variations of V D/V Tphys. However, we found that the effects of VCO 2 are more marked when VR is corrected for Q va/Q. The recognition that venous admixture (Q va/Q) and VCO 2 can change the absolute value of VR despite an unchanged dead space ventilation has several potential implications: (1) Changes in VR may not be attributed to a change in V D/V T if there are associated variations in oxygenation or VCO 2. This may affect the interpretation of the effect of therapeutic manoeuvres such as prone position, PEEP selection, or pulmonary vasodilators on the change in V D/V T. In these examples, changes in VR may be determined by a variable combination of reduction in Q va/Q and V D/V T– but not necessarily exclusively in V D/V T. (2) In patients with more severe disease, the variations in VR may be confounded by the effect of larger Q va/Q. In this case, interventions that affect Q va/Q may disproportionally affect VR and affect the assumption of the underlying pathophysiological mechanisms. (3) Prediction models using VR as a proxy of V D/V T can inflate the range and its prognostic effect. (4) Although VCO 2 disparities may appear a minor problem in general cohort, the VR dependency on this variable makes its use misleading in cases of abnormal VCO 2 or during extracorporeal support, where a substantial portion of CO 2 may be cleared by the membrane lung. In that setting, V D/V Tphys fully reflects the lung status, whereas VR may appear normal or even low. Ventilatory ratio was associated with mortality, but non-ventilatory variables were the chief contributors to high ventilatory ratio values associated with severe illness. It is, however, effective. I’m scared while playing Dead Space, though that feeling alternates with a droopy sense that I’m missing something, most likely the magic of 2008. I’m missing out on a PC to run those sooty, grainy graphics in someone’s dark dorm room. There are options for how you’d like to accomplish this. Maybe you prefer the Plasma Cutter, Pulse Rifle, or the Ripper, which shoots saw blades. I’ve become attached to the Force Gun, a Dead Space 2 acquisition, which uses the game’s gravity manipulation module, Kinesis, to blast away necromorphs until they become piles of rattled bones. I blast away necromorphs that look like overgrown bats and necromorphs that look like praying mantises while a “boss” necromorph lumbers toward me like an intimidating, headless bear. I pause it with Stasis, another gravity manipulation that you can recharge to put enemies in slow-mo—it goes down disappointingly easily with a few hits to the yellow pustules around its joints.

The reference value used for VR computation was 5.3 kPa 0.1 L min −1 kg −1, derived from patients during anaesthesia, 15 where 0.1 L min −1 kg −1 is assumed as the normal VE. To assess whether a similar reference value can be applied to critically ill patients, we selected among our 641 ICU patients 26 patients with ‘normal’ Pa co 2 and V D/V Tphys. The characteristics of this ARDS reference cohort are reported in Supplementary TableE1. The measured VE averaged 0.1 L min −1 kg PBW −1 and Pa co 2 averaged 5.3 kPa (0.4) – which were similar to those found in patients undergoing anaesthesia 5 , 15 and led to identical VR. where CaCO 2, CcCO 2, and CvcCO 2 are the CO 2 contents in arterial, pulmonary (ventilated) capillary, and mixed venous blood, respectively. Kuwabara and Duncalf 11 assumed that tensions and contents are in equilibrium and vary proportionately, and therefore the formula to correct dead space for shunt uses gas tensions instead of their contents. Although this assumption is not strictly accurate, using CO 2 contents or tensions provided similar results (see supplement). Therefore, despite its limitations, the Kuwabara equation is the bestavailable option to correct the dead space. The impact of Q va/Q on V D/V Tphys may be relevant at Q va/Q>0.2–0.3 ( Supplementary Fig.E1, panel A). Indeed, the ‘physiological’ dead space in pathological conditions represents the entirety of the gas exchange dysfunction, as it is influenced both by wasted ventilation (dead space ventilation) and wasted perfusion (Q va/Q). The major limitation of this work, beyond its retrospective design, is that VCO 2 was estimated rather than measured. The computation relies on the Harris–Benedict equation, which estimates the ‘standard’ VCO 2 production based on age, height, and weight (Supplementary material, equation [19]). In ICU patients, we may expect remarkable discrepancies between the actual and the predicted VCO 2. Yet, in the 176 patients in which VCO 2 was measured, the relationship with the computed VCO 2 was acceptable and the bias between measured and computed VCO 2 was –22 (48) ml, despite the large variability of their absolute values ( Supplementary Fig.E4). Any inaccuracy of VCO 2 estimation should affect the V D/V T (Supplementary material, Equation [2]), whereas it would not affect the calculation of VR. The measured and estimated V D/V Tphys values computed in 176 individuals, however, were similar (0.65 [0.13] and 0.59 [0.12], respectively). The physiological dead space (V D/V Tphys) reflects the severity of lung injury 1 and is a powerful prognostic factor in acute respiratory distress syndrome (ARDS). 2, 3, 4 Its use, however, is uncommon, as it requires measurement of mixed expired CO 2 and the simultaneous arterial blood sample to determine Pa co 2. The ventilatory ratio (VR) has recently emerged as an alternative measure of ventilatory efficiency. VR correlates strongly with V D/V Tphys, 5 does not require measurement of mixed expired CO 2, and can be easily calculated from a few routinely collected variables. 6 In addition, the unitless VR is easy to interpret, as it is normalised to a predefined ‘standard’ and quantifies the degree of impaired CO 2 elimination in relation to an expected reference value. However, VR may be affected by factors such as venous admixture (Q va/Q) and CO 2 volume expired per minute (VCO 2), which can alter the absolute value of VR despite an unchanged dead space ventilation. The potential effects of these two factors on VR, in particular Q va/Q, have been described but not quantified. 7 Specifically, there are no clinical data that establish the relative importance of measured Q va/Q on VR, nor the relative importance of VCO 2 on VR when the V D/V Tphys is adjusted for the degree of Q va/Q. These considerations are particularly important in patients with more severe disease, in whom the assumption that virtually all of the variations in VR are attributable to an increased V D/V Tphys 8 may be confounded by the effect of larger venous admixture.

MAX FACTORY

The main results of this study are: (1) the effect of Q va/Q on absolute VR becomes larger with increasing V D/V Tphys; (2) the effect of VCO 2 is also of major significance, particularly when VR is corrected for Q va/Q; (3) VR is a useful aggregate variable associated with outcome; however, it does not only reflect V D/V Tphys but also important contributions from VCO 2 ( Fig 1) and Q va/Q, reflected by Pa O 2/FiO 2 ( Supplementary FigureE2). These data suggest that VCO 2 and Q va/Q contribute to the high values of VR seen in the most severe categories of patients. VR has been proposed by Sinha and colleagues 5 as an estimate of ventilatory efficiency. A theoretical analysis 8 indicated that VCO 2 and V D/V Tphys are both determinants of VR. VR uses as a reference the product of ‘standard’ VE and the ‘standard’ Pa co 2. The standard VE was derived, more than five decades ago, from normal subjects undergoing anaesthesia. 15 Interestingly, we found similar values (0.1 kg PBW −1) in our subgroup of ARDS patients. VR values in the literature range from <1 in the anaesthetised cohorts (indicating the effects of normal V D/V Tphys and Q va/Q and reduced VCO 2) to >5 in ICU patients. The largest values of VR are unlikely to reflect the magnitude of dead space ventilation alone, and it is therefore unclear whether the higher absolute value of VR observed in severe ARDS reflects a worse dead space or the greater contribution of the Q va/Q. Our multivariable logistic regression indicates that VR alone is a useful aggregate variable associated with outcome with odds ratios similar to other studies. 7 Because of the relationship between VR and Pa O 2/FiO 2 ratio, particularly in severe disease, VR should be interpreted accordingly and not considered a bedside index to estimate purely dead space. The physiological dead space and VR have a near-exponential relationship whose level depends on VCO 2. Indeed, we found higher VR in patients with higher VCO 2 ( Fig 1). The association between VR and ICU mortality was examined through univariable and multivariable logistic regression models. To assess the association of VR with mortality when adjusted for covariates which could have a contribution to the VR, we performed a multivariable logistic regression including VCO 2, Pa O 2/FiO 2, and V D/V Tphys. To make an additional comparison of the ORs, we standardised all covariates by subtracting the mean and dividing by their sd. After standardisation, the ORs refer to a unit change in sd of each covariate – therefore giving all covariates numerically similar scales. Model coefficients are reported for standardised and non-standardised data. The aim of this multivariable analysis was not to find a model which included all the factors potentially associated to outcome (i.e. age, mechanical power), but to explore the effects of the physiological variables which contribute to the VR and its association to outcome once adjusted by these physiological confounders.

As for Dead Space, a debut at No.2 means that it has had a much better start in life than last year’s The Callisto Protocol. Widely considered a spiritual successor to Dead Space thanks to being helmed by the original game’s co-creator Glenn Schofield, some may have expected The Callisto Protocol to have made something of a splash. But despite that pedigree, it debuted at an underwhelming No.17 in the NPD sales charts for December 2022. In the entire cohort, V D/V Tphys, Pa O 2/FiO 2, and VR were independently associated with mortality. The OR for mortality of VR and V D/V Tphys were respectively 2.5 (95% CI, 1.8–3.5) and 7.04 (95% CI, 1.9–27.7). The area under the receiver operating characteristic (ROC) curve was 0.64 (95% CI, 0.59–0.68) for VR and 0.66 (95% CI, 0.62–0.71) for V D/V Tphys. When the effect of VR on mortality was adjusted – in a multivariable model – for variables proven to affect VR in the physiological modelling (i.e. V D/V Tphys, VCO 2, Pa O 2/FiO 2), VR was no longer independently associated with mortality, OR adj=1.2 (95% CI, 0.7–2.1). Quantitative chest CT scan and contemporaneous arterial and central venous blood gas samples were available in 153 patients ( Table2 It's all very deep-lore stuff, but the general consensus is that the references to events that occurred in later Dead Space games means EA is planning to remake those games, too—or is at least open to the idea. That theory is bolstered by the earlier discovery of another NG+ text log referring to the Sprawl, a space station on Titan that served as the setting for Dead Space 2. For love, maybe. Isaac wants to reunite with his girlfriend Nicole, a medical officer aboard the Ishimura who barely exists unless you pursue her optional side quest. But no, just as in 2008’s Dead Space, the first letters of the game’s chapter titles spell out N I C O L E I S D E A D, and love was never an option. In the game, it’s a token, something developers put in just so you’d be scared when you realized it wasn’t actually there.All continuous data are presented as means (standard deviation [ sd]) with comparisons between two means performed using with Student's t-test, and with analysis of variance ( anova) between more values. Categorical data were presented as counts and percentages, with comparisons between categories made using χ 2 tests. Linear regression was used to test associations among variables. Call it science fiction survival horror, but Dead Space does the genre proud with an engaging story; action that's tense, fast-paced and extremely violent; as well as atmospheric qualities that will get under your skin and make you jump. It may be a newcomer, but the seeds of an incredible franchise have been sown, and EA's in a great position to reap a phenomenal franchise full of scares. If you like survival horror, action or sci-fi, Dead Space needs to be on your radar. – Jeff Haynes, October 28, 2008 Score: 8.7
