Mae'r Prif Swyddog Meddygol hefyd yn ysgrifennu at ymarferwyr cyffredinol i dynnu sylw at yr hyn a ddysgwyd o gyfnodau cynnar y pandemig ac i annog mwy o ddefnydd o ocsimetreg pwls fel rhan o'r asesiad clinigol. I gefnogi hyn, bydd rhai miloedd o ocsifesuryddion pwls yn cael eu dosbarthu i dimau gofal sylfaenol ledled Cymru i'w helpu i wneud mwy o ddefnydd o’r dull hwn.
The Chief Medical Officer is also writing to general practice to highlight the learning from the early phases of the pandemic and encourage a greater use of pulse oximetry as part of the clinical assessment. In support of this, several thousand pulse oximeters will be distributed to primary care teams across Wales to support them to undertake more pulse oximetry.
