5. Accuracy of interpretation of arterial blood gases by emergency medicine doctors. (PubMed)

Accuracy of interpretation of arterial blood gases by emergency medicine doctors. It is not currently known how accurately emergency medicine (EM) doctors interpret arterial blood gases (ABG). The present study explores this question.A prospective, cross-sectional study of EM doctors was undertaken. An ABG interpretation test was completed by participants. Scores were compared with 'expert level' scores. Confidence with ABG interpretation and satisfaction with ABG training was investigated (...) using a 10 cm visual analogue scale.A total of 37 consultants and 43 EM trainees were analysed. Consultant's and trainee's ABG interpretation scores were 31 (95% CI 29-32.8) and 29.4 (95% CI 27.6-31.2), respectively ('expert level'=40). Consultants scored better than trainees for knowledge of ABG equations; with mean scores of 3.65 (95% CI 3.08-4.22) and 2.51/6 (95% CI 1.87-3.15), respectively, P=0.01. Trainee satisfaction with ABG training was moderate. Consultants were more confident with ABG

review of randomized controlled trials has failed to support this practice. Potential adverse effects from the use of IV SABAs are substantial and include dysrhythmias, hypertension, and hypokalemia.

12. Tales of the Bellevue Hospital Internal Medicine House Staff from the ?60s to Now

, some things about Bellevue have not changed: the Emergency Department and H building, the bright colors adorning the hallways, and the antiquated phones. Indeed, the Bellevue phones likely date back to the opening of the H building in 1975, and still require a measure of dexterity with the phone cords for adequate communication. Having experienced seven hospitals in New York, this writer for one finds it quite magical to work in a place so full of history, and with unquestionably the best ABG (...) syringes and phone interpreters around. Conclusion What struck me the most in this project was the consistency between my interviewees’ stories for each decade. I expected vastly different versions of the same events – à la Raymond Queneau’s Exercise in Style – that I would need to miraculously piece together. Instead, their uniformity nicely illustrates the spirit of camaraderie between residents; they lived the same experiences together. Hearing these stories from the house staff of the ‘60s through

16. BTS guideline for oxygen use in adults in healthcare and emergency settings.

who use oximeters must be trained in their use and made aware of the limitations of oximetry. (Oximetry is a valuable clinical tool but subject to artefact and errors of interpretation.) Arterial and Capillary Blood Gases For critically ill patients or those with shock or hypotension (systolic blood pressure <90 mm Hg), the initial blood gas measurement should be obtained from an arterial sample (see sections 7.1.3, 8.4 and 8.5 in the original guideline document). For most patients who require (...) blood gas sampling, either arterial blood gases (ABGs) or arterialised earlobe blood gases may be used to obtain an accurate measure of pH and PCO 2 . However, the PO 2 is less accurate in earlobe blood gas samples (it underestimates the PO 2 by 0.5-1 kPa) so oximetry should be monitored carefully if earlobe blood gas specimens are used and a repeat arterial specimen should be taken if there is any concern about the accuracy of a capillary sample ( grade D ). Local anaesthesia should be used for all

in the COPD cohort, despite continuing to manage these patients as such as this is the current recommendation. The 2010 Austin et al. study compared titrated oxygen saturations of 88 – 92% in COPD patients to non-titrated high flow oxygen saturations of unknown percentage. One of the limitations noted was the lack of ABGs to record values such as PaO2, which could have been sitting in the high hundreds. Based on the literature search on 5 previous articles, there was a preconceived notion in this study (...) ” simply to “oxygen”. This then results in other clinicians arriving to a MET call with a patient having oxygen saturations of 70% with 2 L/min via nasal prongs because “the doctor said the patient is a CO2 retainer and not to give them too much oxygen”. I think we need to be careful in how people may interpret “holding back” oxygen therapy in a COPD patient, as this is often interpreted as withholding oxygen therapy instead of the intended meaning of not overzealously treating.
