A ventilator mudziyo unowanzo shandiswa pakurapa unobatsira kana kutsiva kufema kwemurwere.Munguva yekushandiswa kweventilator, kune akawanda modhi yemechani yekufefetera yekusarudza kubva, imwe neimwe iine chaiwo zviratidzo uye zvakanakira.Ichi chinyorwa chichasuma nzira nhanhatu dzakajairwa dzekufemesa kwemechani uye kuongorora mashandisirwo avo ekiriniki.
Intermittent Positive Pressure Ventilation (IPPV)
Intermittent Positive Pressure Ventilation inzira yakajairika yekufemesa kwemechani uko chikamu chekufemera chiri kudzvanywa kwakanaka, uye chikamu chekufema chiri pa zero pressure.Iyi modhi inoshandiswa zvakanyanya mukugadzirisa varwere vane chisingaperi chinovharidzira pulmonary chirwere (COPD) uye kumwe kutadza kufema.Nekushandisa kudzvanywa kwakanaka, iyo IPPV modhi inogona kuvandudza gasi kuchinjana uye kufefetera zvakanaka, kuderedza basa rekuita pamhasuru dzekufema.
Intermittent Positive-Negative Pressure Ventilation (IPNPV)
Intermittent Positive-Negative Pressure Ventilation ndiyo imwe nzira yakajairika ye mechanical ventilation apo chikamu chekufema chiri chakanaka, uye chikamu chekupera simba chisina kunaka.Kushandiswa kwekumanikidza kwakashata panguva yekupera kwechikamu kunogona kutungamirira kukuputika kwealveolar, zvichiita kuti iatrogenic atelectasis.Nokudaro, kuchenjerera kunorayirwa paunenge uchishandisa IPNPV mode muchipatara chekudzidzira kudzivirira zvinogona kuipa.
Continuous Positive Airway Pressure (CPAP)
Continuous Positive Airway Pressure imodhiyo yekufefetedza kwemuchina iyo inoshandisa kuenderera mberi kwakanaka kune nzira yemhepo apo murwere achiri kukwanisa kufema zvake.Iyi modhi inobatsira kuchengetedza airway patency nekushandisa imwe nhanho yekumanikidza kwakanaka mukati mese kutenderera kwekufema.CPAP modhi inowanzoshandiswa kurapa mamiriro akadai sehope apnea syndrome uye neonatal kufema kunetsekana syndrome kuvandudza oxygenation uye kuderedza hypoventilation.
Kupindirana Kunosungirwa Kufefetedza uye Synchronized Intermittent Mandatory Ventilation (IMV/SIMV)
Intermittent Mandatory Ventilation (IMV) imodhi iyo mhepo inofefetera isingade kufema kunoitwa nemurwere, uye nguva yekufema kwega kwega haisi nguva dzose.Synchronized Intermittent Mandatory Ventilation (SIMV), kune rumwe rutivi, inoshandisa chigadziro chekufananidza kuendesa kufema kunofanirwa kumurwere zvichibva pane zvakagara zvarongwa zvekufema uye zvichibvumira murwere kufema pasina kukanganiswa kubva kumhepo inofema.
IMV / SIMV modes inowanzoshandiswa mumamiriro ezvinhu apo maitiro ekufema akaderera anochengetwa ane oxygenation yakanaka.Iyi modhi inowanzobatanidzwa nePressure Support Ventilation (PSV) kuderedza basa rekufema uye kushandisa oxygen, nekudaro kudzivirira kupera simba kwetsandanyama.
Mandatory Minute Ventilation (MMV)
Mandatory Minute Ventilation imodhi iyo inofefetera inopa kuenderera mberi kwakanaka pasina kuburitsa kufema kunosungirwa kana kufema kwemurwere kwega kwega kunodarika kufemesa kweminiti yakatarwa.Kana kufema kwemurwere kwega kwega kunosvika pakufemerwa kweminiti yakatarwa, mhepo inofefetera inotanga kufema kunosungirwa kuwedzera mhepo yemhepo kusvika padanho rinodiwa.MMV modhi inobvumira kugadziridzwa kunoenderana nekufema kwemurwere kunosangana nezvinodiwa zvekufema.
Pressure Support Ventilation (PSV)
Pressure Support Ventilation inzira ye mechanical ventilation inopa yakafanotemerwa nhanho yekumanikidza tsigiro panguva yega yega yekusimudzira yekuedza kunoitwa nemurwere.Nekupa yakawedzera kukurudzira kumanikidza rutsigiro, PSV modhi inosimudzira kudzika kwekufemerwa uye vhoriyamu yemvura, kuderedza basa rekufema.Inowanzo kusanganiswa neSIMV modhi uye inoshandiswa sechikamu chekurumura kuderedza basa rekufema uye kushandisa oxygen.
Muchidimbu, nzira dzakajairika dze mechanical ventilation dzinosanganisira Intermittent Positive Pressure Ventilation, Intermittent Positive-Negative Pressure Ventilation, Continuous Positive Airway Pressure, Intermittent Mandatory Ventilation, Synchronized Intermittent Mandatory Ventilation, Mandatory Minute Ventilation, uye Pressure Support Ventilation.Imwe neimwe modhi ine chaiyo zviratidzo uye zvakanakira, uye vashandi vezvehutano vanosarudza nzira yakakodzera zvichienderana nemamiriro emurwere uye zvaanoda.Munguva yekushandiswa kwemhepo inofefetera, varapi uye vanamukoti vanoita gadziridzo nenguva uye ongororo zvichienderana nemhinduro yemurwere uye zviratidzo zvekutarisa kuti ive nechokwadi chakakwana mechanical ventilation rutsigiro.
