Kev ntsuam xyuas ntawm brachial artery teb: pinch lub siab pob ntawm tes thiab simulate brachial artery pulse 1.Simulation txheem qhib airway zaub
2. Artificial tes hauv siab compressions tswb: (1) qhia lub teeb pom kev zoo (2) suab prompting (3) Digital counter display siv qhov tseeb (1-2 cm) thiab tsis ncaj ncees lawm (<1cm lossis>2cm) compression; tswb ntawm tsis ncaj ncees lawm compression
3.Artificial respiration (inhalation): cov cuab yeej tso saib thiab lub tswb nrov (1) Inhalation <30ml lossis> 50ml, qhov taw qhia tsis raug teeb pom kev zoo thiab lub tswb nrov; (2) Inhalation ntawm 30-50ml txoj cai qhia lub teeb pom kev; (3) Kev nqus tau sai heev lossis ntau dhau ua rau huab cua nkag mus rau hauv plab; qhov taw qhia teeb pom kev thiab lub tswb nrov
4. Qhov sib piv ntawm compression thiab ua pa ua pa: 30: 2 (ib tus neeg) lossis 15: 2 (ob tus neeg)
5. Kev khiav hauj lwm lub voj voog: ib lub voj voog suav nrog tsib zaug ntawm 30: 2 lossis 15: 2 piv ntawm compression thiab ua pa ua pa.
6. Kev ua haujlwm zaus: tsawg kawg yog 100 zaug hauv ib feeb 7. Kev ua haujlwm: kev ua haujlwm qoj ib ce 8.kev ua haujlwm: 220v.
