Critical info, for critical care
This is just to find out what molecules are the right size for what sort of extracorporeal removal, if at all. These weights are (mostly) just an approximation, especially as they get into the tens of thousands. Have a go. I found it interesting, hopefully you might, too. NB: Haemodialysis generally removes molecules <20kDa in … Read more
The approach is graphically summarised here. It’s based on Alex Yartsev‘s awe-inspiring Deranged Physiology post, as well as Cohen et al (2016), Lundy & Fischer (2010) and Evenson (2016). The final decision-loop ignores the third possibility, which is that the patient is stable enough to go on living with a chronically-discharging ECF. I had to draw the line … Read more
Select the intervention / condition / study from the drop downs and hit search. alternatively just start typing in the ‘search’ box and it’ll udpate live. If you want all ACS-related stuff, type ACS into the search bar. If you want just the ACS stuff related to NSTEMI, consider the dropdown instead. Search ICU Trials … Read more
Calculate airway or vascular cross-sectional area to understand device proportional occlusion, flow dynamics and resistance.
Convert between tube diameter, gauge, and French size for airway and procedural equipment.
Compare oxygen delivery across devices including low flow, high flow, and non-invasive support.
Estimate physiological shunt to quantify impairment in oxygenation.
Estimate the alveolar–arterial oxygen gradient to assess gas exchange and identify causes of hypoxaemia.
What a stupid name. Nonetheless it’s what we’re stuck with. It is the ratio of LVOT VTI to AV VTI. Given that ALL ratios are dimensionless, you can see my chagrin. VTI LVOT / VTI AV LVOT is measured with pulse wave, to localise it to the LVOT AV VTI is measured with continuous wave, … Read more
What follows is a curated distillation of the ANZICS Statement on Death and Organ Donation. Donation after Circulatory Determination of Death (DCDD) Maastricht classification – only 3 & 4 used in Aus/NZ Category Context Warm ischaemic time Degree of control Category 1 Dead on arrival Unknown Uncontrolled Category 2 Failed resuscitation (ED or ICU) Known … Read more
