I'm not sure about a shorkie weight chart I will try and find out. With small breed dogs they generally stop growing between 6 - 9 months. My guess is about 12lbs for Marley.
The present paper aims to assess the effect of a brief standardized normobaric hypoxia in healthy subjects on the frequency of PB-EPCs, and to evaluate early molecular events implicated in the activation and/or recruitment of these cells.he induction of hypoxia was confirmed by Alveolar Oxygen Partial Pressure (PAO 2) and Spot Oxygen Saturation decreases. Heart rate increased, but arterial pressure and respiratory response were unaffected. The change in PB-EPCs percent from T0 to T1 was inversely related to PAO 2 at T1.
A patient with a 50% shunt breathing 100% inspired oxygen will only get a PaO2 of about 60 mmHg, but doubling their ventilation will maintain normocarbia. Low V/Q ratio. Areas of lung with lower-than-normal ventilation cause hypoxaemia. The blood leaving these areas is part-way between alveolar and mixed venous.
