RER = respiratory exchange ratio (VCO2/VO2) When normal values are plugged into the alveolar air equation it looks like this: An important point is that when air is inhaled into the lung oxygen …

2015年7月8日 · While reviewing a CPET I noticed the patient had a low PETCO2 throughout exercise and an elevated Ve-VCO2 slope. In addition the patient’s minute ventilation was on …

2014年1月1日 · The lungs are the gas exchange organ of the body. The mechanical aspects of the lung, which do of course have a bearing on gas exchange, can be assessed by spirometry …

High chronotropic indexes in the unfit and low in the well conditioned. I will agree however, that when you throw a gas exchange defect into the mix it may be more questionable. In this case …

2013年8月1日 · The VMax229 could be used as a metabolic measurement cart (VO2, VCO2, Ve etc) or as a standard pulmonary function testing system (spirometry, N2 washout lung volumes …
